It is the Skydeck orobservation platform 300 metres high on the 88th floorof the Eureka Tower in Southbank. It claims to be thehighest public vantage point in the Southern Hemisphere.REC Chris Bakes was involved over a considerable timeinstalling power, lighting control, sound and visual effectsfor this exciting, and possibly scary for some, attraction.You can read about Chris and the project and view someother great pictures in the centre pages of this issue.The front cover photo and some of the others are byAlan Beard.fromtheeditor.Welcome to 2008 and the slightly new lookenergysafe. After 10 issues and more thantwo years of the same style and design wethought it was time for a “refresh” of themagazine’s look – nothing too drastic buta change anyway. After all things cannotremain the same.We hope you like the look of the magazine.Whether you approve or not, please let us know.Talking about things not staying the same,there are probably some in the electrical tradeswho wished the Wiring Rules had stayed thesame and are now trying to come to terms withthe new version, AS/NZS 3000:2007, whichhas introduced a large number of changes tothe way RECs, LEIWs and LEIs work.Because the introduction of the new edition ofthe Wiring Rules impacts so many in such a largeway, we make no apologies for giving the topicsome extensive coverage again in this issue ofthe magazine.The centrepiece is the comprehensive four page,easy to read summary of the changes which ispresented as an insert in this issue. Hopefully itwill be of great use to all who need it. It is printedon thicker stock compared to the rest of themagazine to ensure a longer life. It may even beworth laminating.We believe this four page insert is the bestsummary of the new Wiring Rules yet produced.It was prepared by industry experts and firstappeared in the Institute of Electrical Inspectorsofficial publication at the end of last year.Thanks to the Institute for allowing us to publishthis essential information.ESV accepts that coming to terms with the newWiring Rules and adopting the provisions is notan easy matter. Many readers may by now beaware that ESV in conjunction with NECA hasarranged more than 20 information sessionsfor the trade across Australia over the next fewmonths. We have information on the sessionsand the booking form in this issue.The article on page 3 regarding enforcementof the new provisions is essential reading. Thechanges came into force when the new Ruleswere issued in November last year and ESVexpects the trade to work to them as soon aspracticable, but be compliant by 30 June 2008.ESV will exercise discretion if it detects breachesof the provisions up until then.Of course there is a lot more reading in thisissue. For instance there is an article on the newpolicy proposed by ESV in relation to the issuingof the ‘L’ or Supervised Workers Licence – theaim being to encourage holders to progress tobecoming ‘A’ grade electricians. ESV is currentlyconsulting with industry on the proposed policy.Recent electricity and gas “events” involvingsafety are also covered in this issue. For instancea young man is lucky he was not electrocutedwhen a powerline fell on the roof of a front endloader. Similarly two people – one of them an 89-year-old woman – received serious burns in gasrelated incidents.We have a report on the fire which destroyed theRSL hall at Broadford and with it much valuablememorabilia. It is ESV’s conclusion that the fireresulted from an electrical fault.Recently ESV issued infringement notices againstthe suppliers of unapproved Christmas lightingproducts and has been instrumental in recalls ofelectrical products. We have details in this issue.There are of course a number of comprehensivearticles providing electricity and gas relatedtechnical information.There is now another way of seeing Melbourneand its surrounds – 300 metres up in theSkydeck of the Eureka Tower on Southbank.The story of how the power, lighting control,sound and visual effects were installed on thenew observation deck on the eighty-eighth floorof the tower makes very good reading.Hopefully you will agree that there is somethingfor everyone.David Guthrie-Jonesdguthriejones@esv.vic.gov.auadvertisenow!For advertising information and bookings contact Barry Telfer of Barry Telfer Media Services onPh: (03) 9579 7787, Fax: (03) 9579 7782 or by email at btms@patash.com.auBookings are now being taken for the next and subsequent issues of energysafe.Our attractive advertising rates are as follows:Full page > $5000 Half page > $2500 One third page > $1700 Quarter page > $1500Authorised by: Energy Safe Victoria Building 2, 4 Riverside Quay, Southbank, Victoria 3006 Ph: 03 9203 9700Printed by: Energi Print, 2-4 Emily Street, Murrumbeena, Victoria 3163Copyright.

New Wiring Rules –what ESV is doing aboutinforming the tradeabout the changesnew edition mandated from 1 July 2008Director of EnergySafety, Ken Gardner,has re-iterated that thenew edition of the WiringRules – AS/NZS 3000:2007– will be mandated from1 July this year.Ken told energysafe: “When it comes toenforcing the new Rules, ESV’s position mustbe clearly understood by the electrical trades.“Strictly speaking the new Rules apply fromtheir date of publication, which was November12 last year. Therefore, ESV expects the tradeto work to them as soon as practicable, but becompliant by 30 June 2008.an outlineof changesto as/nzs3000:2007,Wiring Rules“We accept that the adoption of the new Rulesfrom a practical and commercial perspective isnot an easy task. Therefore between now and1 July 2008, where breaches of the Wiring Rulesare detected, we will exercise our discretionwhen considering enforcement.”Ken said ESV was also fully aware that becauseof changes to clauses and the structure ofthe new edition, updates have to be madeto the current Electricity Safety (Installation)Regulations 1999.“For instance some of the terms in theregulations do not correlate with the new WiringRules. So work is underway at ESV in matchingthe regulations to the Rules.“Because of the amount of work involved inupdating the regulations, the new version willnot come into force until next year.”This edition of energysafe contains a handy,easy to read and digest four page insert whichexplains the changes that have been madeto the new Wiring Rules. It is a must read foreveryone involved in the electricity industry.The article has been prepared by industryexperts, and is published by kind permissionof the Institute of Electrical Inspectors -http://www.iei.org.auThe article first appeared in the Summer2007 edition of the Institute’s official journal,ELECTRICAL INSPECTIONS.ESVinformationsessionson the NewWiring RulesESV has arranged more than 20information sessions at venues acrossVictoria to enable licensed electricalinspectors, registered electricalcontractors and licensed electricalworkers to get “up to speed” on the manychanges resulting from the introductionof the new edition of the Wiring Rules– AS/NZS 3000:2007.Director of Energy Safety, Ken Gardner, toldenergysafe that while copies of the new Ruleshave been available since the end of last year,it is in 2008 that they will become enforceablefrom a practical perspective.“There are of course many changes in the newedition compared to the previous AS/NZS3000:2000, and ESV accepts that the industrywill need both assistance and time to come toterms with all the new provisions.”ESV is working with NECA in arranging thesessions. Sessions for LEIs will last four anda half hours, while the sessions for RECs andLEIWs will last two and a half hours. Details andthe booking form for REC and LEIW sessionscan be found on page 27.Both the times of the sessions – first thing inthe morning or late in the afternoon - and thevenues for them have been arranged so thatthey are as convenient as possible for the trade.While ESV has organised the sessions andselected the venues, NECA is taking thebookings and helping to publicise the sessions.There will be a total of 21 sessions for RECsand LEIWs between the middle of March andlate May. The selected venues – up to threesessions are being held at some sites – arePreston, Holmesglen, Ballarat, Bendigo,Geelong, Warrnambool, Bairnsdale, LatrobeValley, Wodonga, Shepparton, Mildura, SwanHill and Horsham.The three sessions for LEIs are being held atPreston, Holmesglen and Bendigo.Ken said: “I would urge everyone involved in theelectrical trades to attend one of the sessionswhich have been arranged to assist everyonewho needs to work to the Wiring Rules.“I also want to make it clear that all attendeesat the information sessions will need to haveobtained their copies of the Wiring Rules andto be reasonably familiar with the contentsbeforehand.”There is a nominal charge of $30 per personfor each session.3SUMMER/AUTUMN 2008 ISSUE 11

4www.energysafe.vic.gov.auesv probes salesof appliancesthrough ebayESV is currently investigating the sale of a number ofgas cookers through EBay that have not been certified.What seemed to be a bargain has turned out to be a nightmarefor customers who are now around $1000 out of pocket.Luckily, observant installers recognised the lackof Australian approval labels and refused to fitthe cookers.ESV has also followed up on uncertified waterheaters being offered for sale on EBay assuitable for use with caravans. ESV’s opinionis that they are unsafe and a potential incidentwaiting to happen. The sellers have beenwarned off but tend to reappear some monthslater.It is ESV’s advice that people in the market forgas or electrical appliances must check thatthey have full Australian approval. They shouldalso make their friends and relatives awareof the dangers of purchasing unapprovedproducts.Make sure the seller is properly identified asa company with contact details that are morethan an EBay account name working out of aPO Box.Plumbers and gasfitters engaged to installuncertified appliances should refuse to doso and inform ESV immediately.An unapproved cooker purchased through EBayfor a Victorian home.energysafe advertorial – an article supplied by NecaThe National Electrical and CommunicationsAssociation’s (NECA) EcoSmart Electriciansprogram is a unique industry training andaccreditation scheme for electrical contractorsand their electrical staff.This innovative and ground-breaking programis designed to educate electrical contractorsand their staff about energy efficient products,services and technologies. It aims to equipelectricians with the latest knowledgeand skills to be able to advise customers(domestic, commercial and industrial) on themost energy efficient product and designoptions available, with a view to influencingtheir decision-making towards moreenvironmentally-sustainable solutions andreducing greenhouse gas emissions.EcoSmart Electricians was developed byNECA for implementation initially for Victoriaand then nationally but recent developmentshas seen it released in New Zealand. InVictoria, it has seen an amazing responsefrom contractors wanting to access therapidly growing sustainability market. Forecastto reach 1600 electrical contractors andelectricians, influencing an estimated 30,000households and businesses by the end of2010, the currently listed program is fillingvery fast according to NECA’s Philip Green.“Victoria is leading the way in accessing thismarket and the results for some of thosecontractors who have been at the forefronthave been very encouraging. Clients arelooking for more options these days and it isnot simply about money. Many want to activelyesv consultswith industryon new guidelinesfor issuing “L”licencesESV has commenced a round of industryconsultations with the intention ofintroducing a new policy on the issuingof L class – supervised workers –licences. The policy will also reiteratethat the L class is a three-year one-offlicence which in most instances willnot be renewed.The L licence is aimed at former apprenticeswho have not completed their training after thefour years but wish to remain in the trade.Because they have not qualified, their workneeds to be supervised.The new guidelines call for the licences tobe only issued to former apprentices whodemonstrate an aptitude and commitmentto becoming an A grade electrician, and havecompleted some essential safety modulesand work requirements.Continue on next page.going green is more than trainingreduce their carbon footprint and the firstplace they look is their energy consumption.”EcoSmart Electricians is unique in contentdepth and scope, drawing from the technicalexpertise of major manufacturers andsuppliers in the industry as well asgovernment and community groups.The key to the program, as it is described,is that it is a lot more than just a trainingcourse. “We have deliberately designed thisto provide contractors and their staff withongoing support and information, not just inproducts and technology, but with marketingsupport,” he says. “This last area hastraditionally been a weakness and a negativefor many contractors because it is not coreto their skill set. But what we provide in theprogram is proving to be a major assistancein helping the contractors with their dealingswith their customers.”Information regarding the programcan be obtained by visitingwww.ecosmartelectricians.com.auOr call 03 9645 5533Training commencement datesand locations for 2008Sunshine 1 April >Wodonga 2 April> Mildura 6 May > Berwick 7 May >Warrnambool 20 May South Melbourne4 June > Book early as Placesare limited

During early industry consultation, both NECAand the ETU have indicated support for thepolicy.The policy proposes that the following essentialsafety modules should be obtained before an Llicence is granted. These modules are;> NBB02 Occupational Health and Safety> NE 172 Electrical Wiring and Equipment 1> NUE044 Electrical Safe Working Practices> NUE408 Electrical Installations-testing& VerificationAn ESV discussion paper on the policy saysthat, as an apprentice’s formal training wouldnormally be completed in the first three yearsof an apprenticeship and they would have hadan additional year to catch up and completemodules, it is not acceptable for them to havecompleted less than 60% of their formal training.“There is an argument that if a student is thatfar behind with their studies they either do nothave the ability or they are not serious aboutbecoming an electrician.“A minimum partial completion would be thatthe applicant has satisfactorily completed atleast 15 modules including case units NBB02,NE172, NUE044 and NUE408.“It is not intended that a supervised worker’slicence be an on going licence therefore anapplicant needs to supply with the applicationdetails of how they will satisfactorily completethe outstanding competencies.The licence would be issued subject to theoutstanding units of competencies beingcompleted to the agreed timetable.“Applicants who have satisfactorily completedthe outstanding competencies but have notpassed the LEA will be able to hold a supervisedworkers licence for a maximum of two years,”says the discussion paper.ESV Recommendations1. That before a supervised workers licence isissued the applicant will have satisfactorilycompleted at least 15 modules includingNBB02, NE172, NUE044 and NUE408 andpassed the Safe Work Practice assessment.In addition they will need to present atimetable to show how they will completeall units of competencies within the term ofthe licence.2. Existing holders of a supervised worker’slicence will not be issued a new licenceunless they comply with the above.3. This policy will not apply to those who helda supervised worker’s licence as a result ofholding a B Class licence under the SEC Actwho will be able to continue to renew theirlicence.ESV records show that there are approximately570 L Class licence holders. Of these 49 expirebefore the end of June 2008, a further 95 expirein the second half of 2008 and the rest expire insubsequent years.It is proposed to introduce the policyprogressively. ESV will write to all L classlicence holders and explain the process asit applies to them.There will be further information on theproposed changes in due course.safety advicewhen workingnear powerlinesTwo drivers and a farmer were electrocutedon Victorian farms in 2006 when the traysof trucks delivering lime and fertiliser hitpowerlines. The incidents occurred at WoorakWest near Nhill, Bena in South Gippslandand at Mudgeegonga, near Myrtleford.The following tips should be observed atall times:> Identify all areas where powerlines crossproperties> Obtain a copy of the “No Go Zone” rulesand regulations and study them closely;> Identify all electrical hazards before startingwork. If in any doubt contact the localelectricity distribution company;> Monitor weather conditions. Powerlinescan sag in extreme heat and sway in strongwinds;> Powerlines can be difficult to see at dawnand dusk;> Remember that electricity can jump gaps;> Ensure an ESV registered spotter is on handwhen working anywhere near overheadpowerlines;> Never raise the tray of tipper trucks whenunderneath powerlines;> Relocate bulk delivery storage sites to a safearea away from powerlines;> Display “LOOK UP AND LIVE” stickers onany machinery or equipment which is raisedoverhead.5Power & Gas ServicesBilfinger Berger Services (BBS) is a specialistcontractor with a reputation for deliveringhigh quality, cost effective operations,maintenance and augmentation servicesto owners of major infrastructure assetsincluding power, gas, communications andwater.Power Services:• Electrical & safety inspections• Safety & compliance auditsGas Services:• Maintenance & installation• Leak Detection• Asset construction & commissioningEngineeringDesignConstructionTelecommunicationsMaintenanceMeteringAsset CommissioningSafety AuditsSUMMER/AUTUMN 2008 ISSUE 11Leak DetectionBilfinger Berger Services Power 75 Acacia Road Ferntree Gully VIC 3156 T +61 3 9294 8300 F +61 3 9294 8333Bilfinger Berger Services Gas Level 3, 570 St Kilda Road Melbourne VIC 3004 T +61 3 9946 4900 F +61 3 9946 4950www.bbsaa.com.au

gas industryidentity callsit a day after51 yearsWell known gas industry identity Allen Peacock hasretired after a long and distinguished career lastingmore than 50 years. Since the establishment of ESVmore than two years ago, Allen has been InstallationManager – Gas.Allen Peacock– retiring after51 years6www.energysafe.vic.gov.auAllen became a familiar figure around Victoria with his work, on the onehand in his role as the gas installation inspector in Melbourne’s centralbusiness district for 16 years and then his travels around the statepresenting at training seminars – sometimes as many as 50 in a year.Allen started work as an apprentice plumber and gasfitter at the Gas andFuel’s Fitzroy yard in what was a totally different era to that experiencedtoday. He recalls being part of a team of two who used bicycles to travelaround North Melbourne installing gas appliances and consumer piping.They had to take their materials with them on the bicycles, and if theyforgot anything they would need to ride back to Fitzroy to get it. Whathappened when it rained? “We just got wet,” he said.After graduating to work maintaining gas appliances, Allen was theninvolved for six months in 1962 converting Castlemaine from towns gassupply to tempered liquefied petroleum gas.In 1968 Allen joined the Colonial Gas Company in Box Hill as amaintenance fitter and out-of-hours emergency fitter. In those days,the phones were switched to the fitters’ homes and it was often theirwives who took calls when their husbands were out on other jobs –and sometimes had to endure customer abuse for their trouble!Two years later Allen became an installation inspector and when theColonial Gas Company merged with the Gas and Fuel Corporation in1972, Allen found himself back where he started – at the Fitzroy yard.It was then that he became the installation inspector for the CBD. It wasa busy time – the oil scare was on and most buildings were switchingfrom oil to gas for heating supplies.With the split up of the G&FC Allen worked for the northern region andwhen the chance came to join the newly established Office of Gas Safetyas a gas inspector he took it. He became Installation Manager in 2001and made the switch to ESV in August 2005.Allen is such an expert in his field that his advice and experience is oftenappreciated around Australia – for example, recently he was requested toprovide training seminars in Darwin.“I have enjoyed my time and I am going to miss a lot of it. I certainlyenjoyed travelling and talking to people at the training seminars – it’ssomething I have been doing for more than 30 years. It used to get busyon the training side when new codes and standards were introduced.Sometimes we would be conducting more than one seminar a week,”he told energysafe.Modest about his sporting achievements, Allen did admit to playingfootball at a reasonably high level against the likes of Barry Davis andFraser Evans in their junior days.Later tennis became a passion and he played to a high standard until justa couple of years ago. He was also in charge of the courts at Viewbank forthe Under 16 Australian Championships when it featured the likes of PatCash, Mark Kratzman and Elizabeth Minter.He also admits to being “an old rocker” from way back and is veryproficient on the electric guitar. “Bill Haley And The Comets and their‘Rock Around The Clock’ was my downfall,” he said.ESV and the gas industry wishes Allen a long and happy retirement,which he richly deserves.89-year-old receives burnsin gas cooker incidentESV has investigated an incident atBelmont, near Geelong, in which an 89-year-old woman received burns injuriesfrom her cooker on the same day thather time expired gas meter was changedover.The victim was taken to hospital after herhair caught fire and she received burns to herface, left hand and wrist. She has lived at theproperty for some 60 years while the uprightcooker in question – the only gas appliance inthe house – was installed about 45-years-ago.In a statement provided to ESV, the victim saidshe had been informed by the gas companythat the meter was about to be changed over.Early in February she found a notice in hermail box explaining that the work had beencarried out.She said she rang the telephone numberprinted on the notice and an operator at the gascompany explained the process for turning onthe valve at the gas meter. After doing so, thevictim went back into the house and turned ona gas burner and ignited the flame with a match.As the burner flame was burning correctly sheimmediately turned off the gas control knob.A short while later she placed a lunch packsupplied by the Meals on Wheels service intothe oven, and then turned the thermostatto around mark 350. She ignited the ovenburner with a match. Later she turned off thethermostat knob and opened the oven door.It was then that a flame rolled out settingfire to her hair and causing the burns injuries.The victim told ESV she closed the oven doorand immediately placed a pack of frozen peason her face.She was taken to Geelong Hospital byambulance and returned home after treatment.ESV’s investigations are so far inconclusive.Tests have been carried out on the cookerbut any similar flame roll out has not beenrecreated.

esv assistsinvestigations into firesinvolving evaporativeair conditionersVictoria’s fire authorities - the MFB andCFA - have reported significant increasesin the number of air conditioner andevaporative cooler fires in Victorianhomes over recent months.ESV is working with the authorities investigatingpossible problems with evaporative airconditioners, some of them roof mounted,following increased reports of both fires andincidents where smoke has entered homes.“While these reports are of concern to ESV andthe fire authorities, investigations are at an earlystage and we do not have enough at this timeto ascertain if there is a significant problem withevaporative coolers,” said Director of EnergySafety, Ken Gardner.damaged rooftop evaporative airconditioner examined by ESV recentlyESV has met with CFA and MFB representativesand agreed to investigate as many of thefire reports as possible. In some incidents,investigators have found that fan motor start/runcapacitors have ruptured and produced smokebut not caused fires.“Meanwhile we appeal to all electricians calledout to work on evaporative air conditioners tocheck the state of capacitors to determine ifthere is any deterioration and/or damage, andinform ESV of their findings,” said Ken.“We will of course continue to review thesituation and take whatever action is deemednecessary.”A ruptured fan motor start/runcapacitor detected in one air conditionerElectricalEngineeringManager> Regulate the Safety of Victoria’s electricitysupply infrastructure> Salary range $96,000 – $104,000 plus11% superannuation and vehicle> Southbank locationEnergy Safe Victoria is a statutory authoritythat is responsible for ensuring the safe andefficient supply and use of electricity, gasand the safety of pipelines in Victoria.

8www.energysafe.vic.gov.aunew campaignwarns of thedangers ofoverheadpowerlinesAn extensive public awareness campaign will be conducted byESV across regional Victoria during March warning of the needto “Look Up And Live” when in proximity to overhead powerlines.The campaign is being supported by electricity distributioncompanies, SP AusNet and Powercor.There was a similar campaign in 2007 to coincide with the start of themain season for deliveries of bulk supplies of fertiliser, lime and othermaterials to farms. It followed the three deaths which resulted fromvehicles touching powerlines on rural properties in 2006.Centrepiece of the campaign will be the television commercial producedby ESV in late 2006 and shown for the first time in early 2007 whichdirectly targets truck drivers and farmers. A corresponding radio versionwill be aired across regional stations.“Look Up And Live” brochures, stickers and posters are continually beingdistributed throughout the State to maintain awareness of the dangerswhen working near powerlines.The overriding message of the brochure is: “Be Alert, Be Aware –Overhead Powerlines Are Always There.” One of the stickers, which canbe placed on the inside of windscreens, details the safe working distanceswhich must be observed between trucks, machinery and power poles.A scene from ESV’s “Look Up And Live”television commercialSupplies of stickers and brochures are available from ESV bytelephoning 9203 9700 or 1800 800 158. Alternatively send anemail to info@esv.vic.gov.auDirector of Energy Safety, Ken Gardner, told energysafe that everyoneinvolved in the delivery of materials to farms must exercise the appropriateduty of care.“Farmers and truck drivers need to always ‘Look Up And Live’. Butfarmers have the added responsibility of ensuring that the drop off pointfor deliveries is located well clear of powerlines. Similarly if truck drivershave concerns they should refuse to make the deliveries.”“If as a very last resort there is no alternative but to deliver materialsnear powerlines, then everybody involved has to be fully aware of theprecautions required.“Responsibility for safety must be extended beyond the farm yard.Suppliers of farm materials should ascertain when orders are taken thelocation of the delivery point, the proximity of powerlines and what safetyprecautions are in place should there be powerlines in the vicinity.“Unfortunately, experience shows that everyone – particularly truckdrivers, property owners and farm workers - involved in the delivery oflime, fertiliser and other bulk material to farms is at risk from electrocutionbecause of trucks touching powerlines,” said Ken.

A front end loader dislodged apower pole and the cable droppedonto its roof in a recent incidentat Thomastown.young man’slucky escape inpowerline incidentA young man received a serious electric shockand burn when a powerline fell onto a front endloader at Thomastown recently. He was luckynot to have been electrocuted in the incident.It was reported that the man and two otherswent to visit a friend at a work site which was apaddock covered in mud, large mounds of soiland building rubbish.By all accounts their car got bogged and a frontend loader was used to drag the vehicle out ofthe mud.A chain was connected to the car and thebucket of the excavator and the operation toremove the car was completed successfully.The young man in question then removed thechain from the car and went to remove it fromthe bucket of the excavator.It was at this point that the excavator startedto roll back and in so doing hit a power pole.This caused a 22000 volts conductor to fall andcome to rest on the top roof of the excavator.The victim was taken to hospital by ambulanceafter he received the electric shock and a burnto the inner thigh on his left leg.The electrical protective device operated andisolated the fault.9handy safety hint. tell your customers:Never leave an electrical appliance where it can fall into the bath or basin.Don’t leave unattended with children.

10www.energysafe.vic.gov.auswitching toenergy efficientlightingAn article supplied to energysafe by the Departmentof the Environment, Water, Heritage and the Arts.Lighting plays a very important partin the design of Australian homes andoffices. Demand for both effective andenergy efficient lighting systems by homeowners can at times leave electricalcontractors and electricians wonderingjust what lighting products will createthe best lighting outcome in the mostcost-effective manner.While there are a number of lighting optionsfor today’s consumer, not all of them arecost-effective or the best choice in terms ofefficient energy use. One of the biggest energyoffenders is the incandescent or General LampService (GLS) (pear shaped) bulb, which is aform of incandescent lamp.The GLS light bulb has been available for morethan 125 years, and while inexpensive to buy,typically fails after only 1,000 hours of use andconsumes excessive amounts of electricity,leading to high running costs. In fact almost allof the electrical energy going into these bulbs isconverted to heat rather than light.In February 2007 the Australian Governmentannounced plans to phase-out these bulbs andother inefficient incandescent light bulbs by2009-10. The initiative is expected to reduceAustralia’s greenhouse gas emissions by severalmillion tonnes over the next few years, and cuthousehold lighting costs by up to 66 per cent.GLS bulbs will be phased-out first with otherincandescent lights (including the least efficientof halogen down lights) following in a plannedapproach of phasing-out inefficient lightingwhere effective and efficient alternatives areavailable.Lighting alternatives include compactfluorescent lamps (CFLs) that use around 20per cent of the electricity to produce the samelight, and last four to 10 times longer than theGLS bulb. Compatibility of CFLs with installeddimmers should be checked carefully. Halogenlights that meet the new efficiency standards willalso become available.The Australian Government will use minimumenergy performance standards (MEPS) basedon Australian and New Zealand standards, toensure that only those lighting products thatmeet the specified energy efficiency levels willbe sold in Australia.Standards for CFLs will also apply to ensurethat only good quality products will be sold inAustralia. Aspects covered will include: run-uptime, colour appearance, mercury content, andlamp lifetime.It’s also worth noting, that despite popularmyths, low voltage halogen down lights are NOTan efficient choice for lighting of medium to largespaces. For example, installing ten x 50 wattdown lights will lead to energy consumption ofmore than 500 watts. In many cases, the samejob could be done with CFLs which would useless than 100 watts in total.It’s clear that using more energy efficient lightingis beneficial on a number of levels: both incutting energy bills and reducing impacts tothe environment (less electricity means lessgreenhouse gas emissions).As an electrical professional please rememberthese considerations when next advising yourclients on their lighting needs, ensuring thatwhat you advise and install meets the upcomingAustralian Government requirements.

12letters tothe editorWorking in hazardous areasI refer to the most recent edition of theenergysafe magazine, page 24- MoreCommonly Asked Electricity Questions - c)relating to license requirements to work inhazardous areas.The response given is correct. However itcould have been more specific and addedthat Australian Standard AS4761:2003 -Competencies for working with electricalequipment in hazardous areas (EEHA)addresses the specific competencies requiredto perform hazardous area work and specificallythat Competencies UTE NES 010B, 012B,107B and 214B are the minimum knowledgebase required for installation and maintenanceactivities.“Keep up the goodwork with themagazine - it is reallyvery informative.”I raise this as my work is primarily relatedto design and supervision of installationsin Hazardous Areas and I hold all requiredcompetencies. I find that most electricianswho have not had formal training to theCompetencies stated do not have thenecessary skills and knowledge to performthe work to the required AS2381 installationstandards and many do not know how to fitoff a barrier gland which is fundamental.Perhaps in the interests of promotingcompliance with Australian Standards andencouraging those who would performhazardous area work to do so safely and tothe applicable standards, you could makemention of AS4761 in the next edition.Thank you for your attention.David LittleLegal requirements underthe O.H.&S. ActOn page 24 of the current issue of energysafean answer is given to a question aboutelectrical work in hazardous areas. Theanswer, in part, says ...’Many industriesrequire........ when working in hazardous areas’.Electricians, reading this, could assume that itis an optional requirement/a good idea etc.I think that some mention should havebeen made of the legal requirements underthe O.H.&S. act. There are two separaterequirements:1. Employers (including contractors andsub-contractors) must ensure that theiremployees have proven competence.2. Employees have a legal obligation not tocarry out work on equipment/installationsunless they are demonstrably competent.In practice, if an electrician carries out workin a hazardous area without having provencompetency, they leave themselves open toprosecution. For their protection could youadd something about this in your next edition?There is another legal pathway to enforcingthe use of competent workers.AS/NZS 3000, clause 7.7.2.4.2 mentionsHAW competencies and mandates the useof AS/NZS 2381.1. Clause 1.7 of this standardmandates the use of competent workers.It may even mention the competenciesdescribed in AS/NZS 4761.Keep up the good work with the magazine -it is really very informative.Peter Turnerwww.energysafe.vic.gov.au

Remnantsof SERF type fuses were located below theoriginal switchboard location. A close inspectionfurther revealed that four single 40-wattfluorescent light fittings were also located inthe north west area of the structure.“It is understood that these fittings wereoriginally located within a pelmet structurefor the illumination of a memorabilia displaylocated on the north wall. One of the light fittingsindicated clear evidence of 1/.064 active andneutral copper conductors. Pendulous bulbs ofmolten copper were clearly visible where theywere positioned over the fluorescent’s ballast.“It appears extremely likely that this mayhave been the origin of the fire. The insulationafforded the conductors was not able to beverified as all cable insulation were destroyedduring the fire – none was evident at thislocation.“It has not been established whether the lightfittings were energised at the time immediatelyprior to the time of the conflagration,” said theESV report.The Age reported on the day after the fire thatthe memories of generations had turned to ashin the blaze. Military medals, photos, flags andweapons were among the items destroyed orleft blackened by the fire.RSL sub-branch president Ron Johnsonwas quoted as saying that the 65 memberswere devastated by the loss of the hall and itspriceless memorabilia. “It’s like losing an oldfriend,” he said. “It’s real bad.”Military medals for bravery had been amongthe pieces on display, their ceremonial ribbonsburnt by the flames. Some of them dated backto World War 1.A report in the Herald Sun said three-quartersof the building was destroyed by the fire withthe damage bill estimated at $300 000.13SUMMER/AUTUMN 2008 ISSUE 11

Chris Bakes, REC and Director of OzSpark, has a good head forheights. Which is lucky, because his recent job was about 300metres above the ground: installing power, lighting control,sound and visual effects for Eureka Skydeck 88, Melbourne’snew observation deck on the eighty-eighth floor of theEureka Tower.The Eureka Tower is the world’s tallest residential tower and the Skydeckis the highest public vantage point in the Southern Hemisphere.Chris was involved in the Skydeck project right from the concept stage; infact it was three and a half years before he stepped on site, and two yearsbefore he even saw the drawings. The Skydeck was an ambitious project,with a complex set of highly orchestrated LED sound and vision effectsdesigned by architects and lighting designers to enhance the viewingexperience for visitors.The real fun started when it was finally time to install. The very firstchallenge for Chris and his team was to get all the equipment up to thesite. “There was just a tiny service lift. Any decent-sized switchboards hadto be cut up to fit,” says Chris. “We estimated that there was one guy inthe lift for five weeks, once we added it all up.”When they reached the top, the OzSpark team realised they were aboutto start work, 300 metres up, before the windows went in. “There wasplenty of chicken wire keeping us from the edge,” says Chris.“With the wind and the noise up there, it wasn’t as much fun as it sounds.We worked in August when it was 3 degrees on the ground, and it wasabout minus 6 up there.”“With rigorous safety procedures, even though we were working 88 floorsabove the ground, it wasn’t any less safe than working on the groundfloor.”Installation of the three floors of the observation deck, the retail, café andfunction areas took 10 months, 6 days a week.This was such a challenging job, says Chris, because one of the maindesign objectives was to conceal the complex lighting effects behindceiling baffles. This meant completing just one section of the room ata time. “There were plumbers, builders, electricians and plasterers allworking together, at height,” says Chris.With 35 large panels, each with 256,000 LEDs, the light shines up atthe ceiling and is reflected back down through metallic air ducts andceiling panels, something never done before in Melbourne. With eachlight costing around $3000, this was a major expense and a major partof the installation.“They wanted to keep people guessing,” says Chris. “All the wallschange colour, but you can’t see where the colour change comes from.”The result is a space jam-packed with atmosphere. LED signs thatdetail interesting facts about Melbourne flash across the walls and floors,propelling you around the room as you read them. As you make yourway around the 360-degree windows, ogling at the view, the lights seemto follow. Daylight sensors trigger lights where you are standing, makingit feel even higher than you really are. The lights are matched by audioeffects that echo the sounds of Melbourne so, as you look out at FlindersSt, for example, you hear the trains and the crowds at the station and thetrams rumbling along Swanston Street.These effects are run through a computerised system called Dynalight.Light levels are all pre-programmed. The actual power installation waspretty basic, but the computer control was a highly involved process, saysChris. “There was an extra 40 people behind the scenes just to get thelighting right.“If you don’t feel giddy enough gazing down at tall buildings, then TheEdge “ride” is for you: an elevator-like cube moves 3 metres out from thebuilding so you are suspended for a few minutes over the city. Just asyou get used to the view, the frosted glass on all six sides of the cubesuddenly goes clear, and it appears that there is only a thin layer of clearglass between you and the world below you.Chris is happy to give away a couple of trade secrets: “The glass ismade up with LED panels, so when there is a current run through theglass, it gives the perception that it is cloudy and frosted. When it isde-energised, it goes clear. That was a basic switching program runthrough the computer.”MAINTENANCE OFFICER GRAHAM SKINNER WITH THE DIESELGENERATOR THAT WAS, UNTIL ABOUT 18 MONTHS AGO, THE BACKUPPOWER SUPPLY FOR THE ROYAL CHILDREN’S HOSPITAL.“We worked in August when it was3 degrees on the ground, and it wasabout minus 6 up there.”“It was a very simple idea with a very complex execution. A lot of thehard work was done in the drawings and working out the relays.”This is one project Chris Bakes certainly won’t forget. “The view wasincredible and working up there certainly gave us a different perspectiveof Melbourne. The hot air balloons floating around you was a nice way ofstarting the morning, and seeing the Commonwealth Games fireworksbelow us was fantastic.”Eureka!> Eureka Tower took 4 years to completeand cost approximately $500 million.> The tower used 110,000 tonnes of concreteand weighs 200,000 tonnes.> The top of the tower can flex up to 600mm inhigh winds.

Live antenna mounting bracketwarning from esv:metering antennamounting bracketfound to be “live”Late last year ESV issued a Safety Alert after a licensedelectrician received a shock while working nearelectrical metering communications equipment.At the time he was installing cables in a metal duct located next to theelectrical metering panel, and made simultaneous contact with theduct and a “live” metallic antenna mounting bracket associated withthe metering equipment.The antenna mounting bracket was fixed to the meter panel with two23mm self-tapping metal screws.The screws protruded though the front and the rear of the meter paneland penetrated into the single insulation cables within the meteringenclosure, therefore allowing the screws and the metal bracket tobecome “live”.This method of installation is contrary to the fundamental safetyrequirements of AS/NZS 3000:2000 in that the bracket should havebeen attached with insulated screws.As a result of the screws penetrating the single insulated cable, theantenna mounting bracket was measured to be “live” at 247.9 VAC.Warning: metallic antenna mounting brackets fixed with metal screwsshould be treated as “live”.ESV estimates there are more than 5000 sites across Victoria wherethere may be similar installations.17handy safety hint. tell your customers:Do not use a portable electrical radiator in the bathroom.A permanently installed heater is much safer.energysafe advertorial – an article supplied by Protectfund administration software a winnerA six month independent research projecthas documented the importance of Protect’sdecision to commission purpose built, leadingedge fund administration software.Rosy Buchanan & Associates draft reportsets out the effectiveness of the administrationsoftware and the subsequent savings toemployers.In place since July 2006, the administrationsoftware allows employers to work online– to lodge both paperwork and paymentelectronically.“Information …… from …… businesses ……overwhelmingly endorse the time savings ……”,the report says.“…… 90% provided feedback that the timespent on monthly returns had been reducedby between 50% - 80%”, the report added.With both industrial and commercial obligationsto provide paperwork and payment withinbusiness rule guidelines, the administrationsoftware is proving a winner for employersand Protect.1,250 employers provide monthly contributionsfor 27,000 employees.

18contents.amendments tothe ElectricitySafety Act toensure unsafework is rectifiedThe Electricity Safety Amendment Bill 2007 – the subjectof two articles on page 14 of Issue 10 of energysafe –has become law.The new Act amends the Electricity Safety Act 1998 to:> mandate submission of and, once approved, compliance with electricitysafety management schemes by major electricity companies, namelyelectricity transmission and distribution owners or operators;> harmonise the safety management scheme regime in the ElectricitySafety Act 1998 with the gas safety case regime in the Gas SafetyAct 1997;> require registered electrical contractors and licensed electrical workersto rectify their defective electrical work that is unsafe;> improve the representation of the railway and tramway industrieson the Victorian Electrolysis Committee.As a reminder for readers on what the legislation contains, the Actprovides that Energy Safe Victoria may, by written notice, require aregistered electrical contractor or licensed electrical worker that carriedout unsafe work to rectify it at no additional expense to the customer.Penalties apply for non-compliance with a rectification notice.However, an REC or LEIW can avoid a notice under the bill, and the riskof a penalty for non-compliance, by rectifying unsafe work promptly -as he or she would be contractually bound to do anyway.By providing for the issue of rectification notices, the Act ensures thatdefective work that is unsafe is made safe as soon as possible, andregardless of whether the consumer chooses to enforce his or hercontractual rights.Compliance with a notice from ESV to rectify unsafe and defective workis subject to the right of review by the Victorian Civil and AdministrativeTribunal.The rectification work is to be at no additional expense to the customer.Rectification of unsafe defective electrical work may include the labellingof switchboards, the securing and protection in position of cables and thesecure installation of equipment, said the Minister.The Act also makes it mandatory for Victoria’s electricity transmission anddistribution network operators to submit electricity safety managementschemes (ESMS) to ESV every five years.An ESMS specifies the assets or operations to which it applies, thehazards and risks to persons and property arising from those assets oroperations, and the safety management system to be followed to minimiseas far as practicable those hazards and risks.The benefits include lower compliance costs under the ESMS regimecompared to prescriptive regulations and improved safety performance.By aligning, where appropriate, the gas and electricity safety regimesthe Act reduces the regulatory burden for those entities operating inboth the electricity and gas industries.The Act enables ESV to conduct audits to determine compliance withan ESMS.www.energysafe.vic.gov.auALL YOUR DOWNLIGHTPROTECTION COVEREDInsulguard Enclosure & Retro Downlight Covers.The simple and effective way to protect downlights.InsulguardDimensions:310mm(W)x200(D)x220(H)Insulguard -Downlight Enclosure● Protects downlights & transformersfrom thermal insulation● Treated with non-toxic fire retardant● Made from environmentally friendlyrecycled pulp● Complies with wiring rules (AS/NZ3000:2007) Recessed luminaries -clause 4.5.2.3 method (b)● Tested to AS1530-Part 2 (FlammabilityTest)● Independently heat tested to 600°c● Packs flat for easy storage● Pre-cut 70 - 90mm downlight holeRetro -Downlight Cover● Complies to new electrical wiring rulesfor downlights● Retrofit existing downlights● Small and compact● Can be placed through existingdownlight hole● Two sizes to cover most downlightinstallations: 70mm & 90mm● Metal perforation for air circulation● Transformer attachment includedCatalogue No. DLGRetroCatalogue No. DLCL (90mm), DLCS (70mm)Note: does not includetransformer or downlightomegapower.com.ausales@omegapower.com.auVIC(03) 9793 6111NSW(02) 9734 9944QLD(07) 3216 2799SA(08) 8340 9200WA(08) 9475 0777

esv fines two importersfor supplying unapprovedChristmas lightsESV has issued Infringement Noticesagainst two importers for supplying oroffering to supply unapproved Christmaslights. The offences were detectedduring regular ESV compliance audits atthe premises of the parties concerned.ESV served a $2,202 Infringement Noticeagainst a company and a $440 Notice againstan individual - in accordance with Part 11A ofthe Electricity Safety Act. .Both the company and the individual were alsorequired to provide a written statement to ESVadvising:>why these Christmas Lights were being soldwithout Australian electrical safety approval;>actions they are taking to ensure that allprescribed electrical equipment withoutelectrical safety approval and any unsafeelectrical equipment, is immediately withdrawnfrom supply;> detailed list of all retail outlets they havesupplied unapproved Christmas Lights toduring 2007;> actions they are taking to retrieve and destroyall unapproved and unsafe Christmas Lightsthat they and the retailers they supplied stillhave in stock;> reason(s) why they should not conduct arecall of the already sold unsafe ChristmasLights; and>that they understand the requirements ofSections 54, 57(2), 63 & 65 of the Act.They were also warned that ESV will continueto monitor equipment supplied by them andmay issue other Infringement Notices or otherUnapproved Christmaslighting productsdetected during ESVauditspenalties for each breach of the ElectricitySafety Act 1998.ESV indicated to both parties that it wasparticularly concerned that the wiring on manyof their Christmas Lighting products did nothave adequate insulation thickness for safeoperation at 240Vac and could result in theuser receiving an electric shock.In one instance, the individual had suppliedabout 200 units of one unapproved set ofChristmas lights before ESV directed it to stopsales.Both importers were advised that, under Section57(2) of the Electricity Safety Act 1998:“A person must not supply or offer to supplyelectrical equipment prescribed under subsection(1) unless the equipment –(a)is approved by ESV and is marked asprescribed; or(b) is approved by a prescribed authority or,under the regulations, is deemed to beapproved; or(c) is certified in accordance with a prescribedmethod or prescribed process.”Decorative Lighting Outfits (including ChristmasLights & Rope Lights) and components(including Plug, Supply Cord and ControlDevices) have been prescribed classes ofelectrical equipment for many years with themost recent prescription being on 7 August2003 by notice published in the VictorianGovernment Gazette No. G31, on 31 July 2003.Both the company and the individual hadpreviously been advised on two occasions byESV in recent years not to supply unsafe andunapproved prescribed electrical equipment.fireauthoritiesjoin esvin warningon unsafeChristmas lightsThe MFB, CFA and ESV received positivecoverage when they warned the community in amedia release issued in December 2007 againstbuying cheap decorative lighting products whichhave not been approved for supply by Australia’selectrical safety regulatory authorities.Unapproved lights can be dangerous with thepotential to start fires in homes and causepeople to receive electric shocks, the authoritieswarned in the release.The extensive coverage included an interviewwith ESV’s Executive Advisor Communicationsand Public Relations, David Guthrie-Jones, onRadio 3AW’s top rating Ernie Sigley program.The release said Christmas tree lights and otherelectrical products are only approved for salein Australia once they have been exposed torigorous testing by accredited test agencies.The media release also asked people aware ofunapproved products being offered for sale tocontact ESV.Handy safety hint.Tell your customers:Even if you consider yourselfto be handy around the home,DO NOT attempt electricalwork of any kind.

20Qsand Ascontents.Q Can I use two flexible hoses from a coppermanifold as consumer piping if each hoseconnects to one appliance only. The hoseswill be installed inside the caravan forprotection?A The answer is no. The use of a hose asconsumer piping is only permitted forconnecting one appliance.Q If I can install multi-layer (composite) pipingabove ground as long as protected fromUV rays, why can’t I install UPVC aboveground?A The middle layer of composite piping is metal,and has been accepted for above grounduse. UPVC has no metal component andhas not been accepted for above grounduse. A number of incidents have occurredwhen UPVC has been used (illegally) withinpremises and fittings have been snapped off.Q We wish to install a by-pass around a safetyshut-off system in the consumer piping forservicing purposes.A You would have to formally apply to ESVfor acceptance to install the by-pass.Acceptance would only be given in caseswhere continuation of gas supply is essential,eg in hospitals and some institutions etc.ESV would require details ofAre you feelingthe pressure?This article was written by KevinNathan, an ESV Type B Gas Inspector.Pressure test points are one of the gasfittersmost useful aids. They provide access to theconsumer piping and valve train for the testingof supply pressures, setting of burner pressuresand components, such as regulators and lowpressure cut-off devices, etc.The use of pressure points is also essentialduring commissioning to ensure the correctfunction of regulators, safety shut-off valvesand leakage detection systems etc.It is important to note that AS 3814 Industrialand commercial gas-fired appliances, Clause2.12.3 states that -A gas pressure test point shall be provided witha means of sealing the outlet and, where theoperating pressure exceeds 7 kPa, it shall be ofa self-sealing type or fitted with a manual shutoffvalve.The following photographs show the correctand incorrect use of test points at pressuresgreater than 7kPa.A filter operating at 70 kPa andinstalled upstream of an OPSOregulator.

Later in the day he decided to usethe appliance, followed the instructions hehad been given and activated the igniter.The BBQ then erupted into flames, The CFAattended to put out the fire and the victimwas taken by ambulance to hospital.During its inspections of the BBQ, ESV foundthat the POL screwed connection into thecylinder valve was loose. This threaded brassPOL connection could be hand tightened intothe cylinder valve socket an additional one andone half revolutions.ESV’s investigations included interviews withrepresentatives of the assembly companyand its contractor who assembled the BBQin question.21SUMMER/AUTUMN 2008 ISSUE 11thepotential ofproducingelectricityfrom hotrocksExploration work is already underwayin parts of Victoria assessing thepotential for producing base loadelectricity from naturally occurringsubterranean heat – in other words“hot rocks”.Permits for exploring geothermal energysources were awarded in 12 areas to fivecompanies last year, with a further 19 permitsto be offered in April this year, the Ministerfor Energy and Resources, Peter Batchelor,announced just before Christmas.He said the five companies already awardedpermits had committed to spend more than$64 million over five years, with work alreadygetting underway in Gippsland.“The next tranche of permits will allowcompanies to search for geothermal energypotential across more than 154,000 sq km ofVictoria previously unexplored.“In the last two years, the number ofcompanies exploring for geothermal energysources in Australia has doubled.“This second release of permits will help ensureVictoria’s geothermal potential is realised,” saidthe Minister.He said the geothermal industry in Victoria hadhuge potential and was entering an excitingperiod of growth.Apart from reducing dependence on carbonemitting forms of electricity generation,producing baseload power from naturallyoccurring subterranean heat will boost regionalcommunities and the State economy.“The geothermal industry is still in the earlystages of development in Victoria. TheState has abundant renewable resources,but at this stage, renewable energy onlyaccounts for around four per cent of electricityconsumption,” he said.In hydrothermal geothermal systems, deepgroundwater that has been naturally heated tosteam temperatures is brought to the surfaceand used to turn turbines.In dry rock systems, water is injected into hotrocks and returned to the surface once heated.

22www.energysafe.vic.gov.aucontents.pigtails andmanifolds forlpg cylinderinstallationsA commonly asked question to theGas Technical Help Line is which typeof pipe is acceptable for use betweenan LP Gas cylinder and the regulator.AS 1596 and AS 5601 require either a flexiblehose assembly with an excess flow valveupstream of the assembly, or copper tube witha nominal size of 6 mm and a minimum wallthickness of 1.22 mm.When a number of cylinders are required,it is normal practice to manifold them. Therequirements for copper pigtails apply to themanifold. Manifolds to the correct thicknessand size are readily available from reputablesuppliers who can verify the standard of thematerials.Manufacturing a manifold from copper tubeshould only be considered where the use ofa commercially available type is not feasible,and after consulting the gas supplier. Type Acopper would normally be specified.Remember too that the cylinder regulator isto be rigidly fixed to an adequate means ofsupport that is independent of the cylinder.Connecting the regulator directly to thecylinder is only acceptable for cylindersexceeding 400 litres and which are fittedwith a lockable dome.testing forconsumerpipingenergysafe advertorial – an article supplied by Safety In Action 2008safety inaction 2008“for peoplewho makesafetyhappen”Installers should be aware that ESV GasInspectors are no longer testing new consumerpiping for leakage. It is the installer’s responsibilityto carry out any required test to the correctstandard before gas is supplied.Inspectors will now require verification of anacceptable test before a Gas Supply Approval[GSA] is sent to a gas distribution business.Where a low pressure test (less than 10 kPa) iscarried out (eg using a water-filled manometer),verification is by correctly entering the requiredinformation in the Test Report Section of theGasfitting (Compliance) Notice. If the informationis not supplied or is incorrect, a GSA will not beissued.For test pressures exceeding 10 kPa, and wherea manometer test is not suitable, a Test Sheetmust be completed by the installer and submittedwith the Gasfitting (Compliance) Notice to verifythat a successful test has been carried out to theappropriate standard (AS 5601).Test Reports are also required where additionalwork has been carried out and gas is alreadyavailable. This will mean that older styles ofGasfitting Notice are obsolete and may not beaccepted if submitted without a Test report.Gasfitting Notices and a sample Test Sheet areavailable from the ESV web site. Look under thetab ‘For Gas Professionals’, and then ‘ComplianceCertificates and Gasfitting Notices’. They are alsoavailable at selected plumbing supplies,ESV offices, most PIC Regional Offices.If further explanation or clarification is required,please call the Gas technical Help Line on1800 652 563.Principal SponsorAhead of April’s Safety In Action workplacesafety trade show, WorkSafe Victoria hasstressed the need for industry to stay abreastof the latest safety measures.“Everyone in the workplace should have aninterest in health and safety.

The preferredmethod is to install a room-sealedappliance (one designed to take itscombustion air from outside andremove the products of combustionto outside).For other appliances -> the burner and any pilot orcombustion air intake must be450 mm above floor level; or> a permanent, sealed, wall at least450 mm high must be erected aroundthe appliance. The location of thewall must allow adequate access forlighting and servicing the appliance.> there must be a warning sign tothe effect that that flammablevapours are not permitted within3 metres of the appliance.Always ensure that the applianceis protected from vehicle damage.For further details, refer to AS 5601,Gas Installations, or call the GasTechnical Helpline on 1800 652 563.Organiser of Safety In Action and MelbourneMaterials Handling, Marie Kinsella, said thepractical nature of workplace safety meant thatit was important for anyone concerned withsafety to be aware of the spread of solutionson offer.“The bottom line is that you need to be ableto demonstrate you’ve taken all reasonablesteps to make your workplace safe, which inturn means you can’t afford to overlook newsolutions as they come onto the market,” shesaid. “In practice, staying across everything isa huge undertaking, which is why we get 350or more safety suppliers in one spot everyyear at Safety In Action.”Ms Kinsella said the 12,000 square metres ofthe Safety In Action and Melbourne MaterialsHandling shows was allocated to ensure aspread of specialists.Visit Safety In Action and Melbourne MaterialsHandling, which run from April 29 to May 1 atthe Melbourne Exhibition Centre.

split system airconditioners– clearancesto gas metersSplit system air conditioners are very popularbut selecting an appropriate external locationcan be challenging.ESV and the gas distribution companies havebecome concerned at the number beinginstalled adjacent to gas meters.Generally there is no hazard under normaloperating circumstances. However, most gaspressure regulators (located at the inlet to themeter) have a relief function. This means that if afault condition occurs, an amount of gas will bereleased to atmosphere. The air conditionercan then act as a point of ignition for theescaping gas.As a general rule of thumb, an air conditionermust not be installed within 1 metre of a gasmeter assembly or its proposed location.A similar hazard affects LP Gas installations,but a much greater clearance is required,depending on the type of cylinder installed.In-situ fill cylinders require a clearance of 3.5metres at ground level, and for exchangecylinders it is 1.5 metres.Failure to observe these clearances couldresult in gas supply being withdrawn.gas heating inoutdoor situationsOutdoor heating in restaurants and clubs is becoming more popular,especially in areas being created for smokers. The use of differenttypes of heaters in locations that are some times questionable isbecoming more prevalent.If appliances are being considered for installation in locations that they were not originallydesigned for, contact should be made with ESV before work commences. In some instancesagreement will have to be obtained from the manufacturer but the general requirements ofinstallation instructions must be adhered to.Even with the manufacturer’s agreement, any variation from the installation instructions musthave ESV approval.Appliances certified only for indoor use may be acceptable in quasi-outdoor situations providedweather protection is adequate. Such approval will be considered on a case by case basis.Special care would need to be taken in regards to any electrical connections.Some of the installations that ESV has been asked to accept but rejected had inadequateclearances, insufficient heights for the output of the heater, unacceptable access for servicingor poor flue discharge methods.Remember it’s better to check whether the installation would be acceptable rather thanrisking having gas supply refused or even worse, creating a potential hazard.Call the Gas Technical Help Line on 1800 652 563 for advice.Handy safety hint. Tell your customerIf an appliance needs adjusting or cleaning, switch offthe power and pull out the plug – but not by the cord.23SUMMER/AUTUMN 2008 ISSUE 11

electrical homesafety inspectionTHESE ORIGINAL VACUUM VOLTAGE SENSING RELAYS ACHIEVED UNDER ANDOVER VOLTAGE PROTECTION. IF THEY TRIPPED, THEY WOULD BRING ON THEGENERATOR SUPPLY. INSTALLED IN 1960, THEY WERE CRITICALLY IMPORTANTFOR THE SUPPLY TO THE HOSPITAL. THIS TECHNOLOGY WAS REPLACED IN 2006.Mike and Bev Ballagh with the certificate ofelectrical inspection issued after the installationof their new meter.brings peace of mindfor Victorian couple24www.energysafe.vic.gov.auThe following is an article prepared by ESV forpossible publication in specialist newspapersavailable for Victorian holders of the SeniorsCard. It is hoped the article will further promoteESV’s electrical Home Safe Inspection Schemeand the $50 rebate available for Seniors Cardholders who book and pay for an inspection.East Doncaster couple, Mike and Bev Ballagh, now have peace of mindthat their home is electrically safe thanks to an authorised electrical HomeSafety Inspection of their property arranged through Victoria’s electricityand gas safety regulator, Energy Safe Victoria (ESV).ESV introduced the scheme in 2005 to help address concerns about thepoor and sometimes possibly dangerous state of electrical wiring systemsand other installations existing in many homes across Victoria.The electrical Home Safety Inspections are conducted by experts– licensed electricians and/or licensed inspectors who have undergonefurther training and assessment to become authorised for the task byESV.Last year ESV introduced a new initiative – a $50 rebate for SeniorsCard holders, who arrange and pay for inspections.“We read about the scheme in ‘The Senior” newspaper and thought itwas a great idea particularly for people in our position. We now have asafe home electrically and at our stage of life such peace of mind is veryimportant,” said Mike, a retired Tattersall’s employee.The couple built their home 38 years ago and to make more room for theirthree sons, a daughter and an aged mother, who was living with them,they added an additional storey to the property some 15 years later.They arranged the inspection through the ESV website atwww.esv.vic.gov.au“When the extension was built, the electrical installation was not upgradedin any way. After reading the article about the scheme we did not knowif we had any problems but decided it would be a good idea to find out.After all one often hears about house fires put down to electrical causes.”Following the inspection, the couple received a comprehensive reporton the state of the electrical installation with a follow-up email from theinspection company explaining in “layman’s” terms what issues neededto be addressed. The report recommended that some remedial workshould be undertaken as soon as reasonably practical.Mike said: “A significant problem detected during the inspection was aninadequate supply of electricity to the house. When the house was builtwe had one television and nothing like the electrical equipment whichwe have obtained over the years. The inspection detected heat damagebecause of overloading of the electrical installation.“It was recommended that we needed a new consumers mains, mainswitchboard with surge and safety switch protection and main earth,and we were happy to arrange for the work to go ahead.“I would strongly recommend that other home owners arrange anelectrical Home Safety Inspection. I would even go so far as suggestingthat people have a social responsibility to ensure their property iselectrically safe.“Receiving the $50 rebate off the cost of an inspection for Seniors Cardholders was certainly a bonus as far as we were concerned, and hopefullyit will be for others.“I think ESV does a great job promoting the electrical Home SafetyInspection scheme and providing the rebates. The scheme providespeace of mind for older people,” said Mike.In particular, ESV encourages everyone with a property that is 25 yearsold or more to arrange an inspection. The electrical wiring needed forlights, cookers, televisions and other appliances may no longer be upto scratch.Government inquiries into the Yallourn Mine collapseIn early December last year, Minister for Energyand Resources Peter Batchelor announced twoinquiries into the collapse at the Yallourn opencut mine.The northern wall of TRUenergy’s minecollapsed on 14 November 2007 resulting in theLatrobe River flowing directly into in the mineuntil a diversion could be put in place.Although the incident disrupted mining andpower production at the Yallourn W powerstation, power supplies to the state were notdisrupted.The Minister said the inquiries would separatelyinvestigate the facts and causes of whatoccurred and compliance with mining licenceobligations.“This was a major incident resulting in potentialsignificant environmental impacts and while noonewas hurt, we need to ensure the highestsafety standards are in place across theindustry.“It is crucial that we understand what causedthis incident, so we can prevent further incidentsof this kind.“Achieving maximum safety and protecting theenvironment during mining activities is a toppriority for this Government, and I know it is alsoa top priority for the industry,” said the Minister.The first investigation by Department of PrimaryIndustries’ (DPI) inspectors into TRUenergy’sperformance against its mining licenceobligations started at the end of last year.A second inquiry into the facts and causesof the mine wall collapse was scheduled tostart early this year. It will be independentlyconducted by a person with specialist expertisewho will be appointed as Mining Warden by theGovernor in Council.“There are two investigations because DPIis responsible for regulation of the miningindustry under the Mineral Resources(Sustainable Development) Act and willtherefore investigate the compliance issues.“A Mining Warden, however, has broaderpowers of investigation including the abilityto enter any land, summons a person to giveevidence on oath and require the productionof documents.“By setting up this second inquiry we aremaking sure that all the facts can be thoroughlyinvestigated independently of government.The DPI investigation team will cooperate fullywith the mining warden’s investigation,”said Mr Batchelor.The investigations are expected to becompleted during the first half of this year.

electricityQsand AsQ. Is a refrigeration mechanic with a D licence permitted to install240v interconnect cables for split system air conditioners? Someunits are direct wired through an isolator and some units plug into asocket outlet. Under what circumstances if any are the interconnectcables regarded as part of the appliance and able to be installed bya competent person?A. The installation of interconnect cables that are 240 volts is deemedto be electrical installation work under the Section 3 definitions in theElectricity Safety Act 1999, and is therefore not within the scope of aD licence holder. The person undertaking this work needs to be anA class (formerly E licence) holder.Q. If I have installed a cover over my extra low voltage (ELV) downlightscan the distance be decreased from those that are shown in Figure4.7 of AS/NZS 3000:2007?A. The requirements are outlined in Clause 4.5.2.3, which states:“4.5.2.3 Recessed luminairesRecessed luminaires and their auxiliary equipment shall be installed ina manner designed to minimise temperature rise and prevent the riskof fire. The temperature rise at the rear of a recessed luminaire shall belimited to prevent damage to adjacent materials.This requirement shall be satisfied by one of the following methods:(a) The use of a luminaire specifically designed and certified by themanufacturer to permit—(i) contact with combustible materials; or(ii) enclosure or covering by thermal insulation material, asappropriate to the location of the luminaire.(b) Installation of the luminaire within a suitable fire-resistant enclosure.(c) Provision of required clearances from combustible and thermalinsulating material as specified by the manufacturer of the luminaire.(d) Provision of the default clearances from combustible and thermalinsulating material as specified in Figure 4.7.Where manufacturer’s installation instructions that specify requiredclearances are not available, the luminaire shall be installed in accordancewith (b) or (d).NOTE: In the case of a suitably designed luminaire, the installation instructions may specify thatno clearance is required.Recessed luminaires and their auxiliary equipment shall be installed insuch a manner that necessary cooling air movement through or aroundthe luminaire is not impaired by thermal insulation or other material.Where thermal insulation is of a type that is not fixed in position, e.g.loose fill, a barrier or guard constructed of fire-resistant material shall beprovided and secured in position to maintain the necessary clearance(see Figure 4.7).”Therefore if there are no other measurements stated with themanufacturer’s instruction then (b) and (d) are to be applied. With no otherinformation the default measurements of Figure 4.7 are to be adhered to.Q.On a large site that is multiple occupancy where does the prescribedelectrical work end? Do I require more than one prescribed certificateof electrical safety?A.In the Electricity Safety (Installation) Regulations 1999 the requirementsof prescribed electrical installation work are outlined in Regulation 406.When seeking to identify the parts of the electrical installation work thatare prescribed electrical work Regulation 406 (a) and (b) provide theanswer by stating:“406. Prescribed electrical installation work(1) For the purposes of section 45 of the Act, “prescribed electricalinstallation work” means work on all or part of any of the followingelectrical installations if they are ordinarily operated at low voltage ora voltage exceeding low voltage—(a) consumers mains, main earthing systems, consumers terminalsconnection devices and those parts of main switchboards thatare related to the control of installations and the protectionagainst the spread of fire;(b) sub-mains, earthing systems and any distribution boardsrelated to the control of individual occupiers’ portions of multipleinstallations unless the occupier has immediate and unimpededaccess to the main switch or switches controlling the whole ofthe multiple installation.”It is important to understand that Regulation 406(b) details therequirements for the distribution boards related to the control of theindividual occupiers portions of the installation. This means that theperson who owns the individual occupancy needs to be able to haveunimpeded access to the main switch or switches or otherwise theprescribed electrical work continues to the switch that the individualoccupier does control. This is usually the isolating switch contained inthe switchboard in their unit/apartment or townhouse, so this is wherethe prescribed electrical work ends.With respect to the number of prescribed certificates of electrical safetythat are issued, then the Electricity Safety (Installation) Regulations1998 provides the answer in Regulation 410(3) which in Part (c) requiresthe address and postcode of the electrical installation. Therefore if theelectrical installation address is Unit 3012, XYZ Towers, Melbourne,it would be understood that each unit would require its own prescribedcertificate of electrical safety, to accurately record the electrical installationwork performed at that address.25SUMMER/AUTUMN 2008 ISSUE 11esv reminder on IP 23 light fittingsFor many years there have been IP 23rated light fittings available for useon electrical installations and manyregistered electrical contractorsand electrical workers have soughtto use them.ESV recently received complaints from somecustomers about these light fittings andtherefore reminds RECs and LEIWs of thefollowing.When installing any fitting or equipment inan area that requires a degree of IP rating,the installer must meet the fundamentalrequirements in AS/NZS 3000:2007. Clause1.7 details the requirements for the selectionand installation of electrical equipment andcovers the essential fundamentals, installationwork practice, equipment selection and dampsituations.The fittings that have been bought to theattention of ESV are a PVC composition and area batten holder style. The fitting itself is IP ratedand when the consumer inserts a standardglobe they are finding out that the globe failswhen it rains due to the heat of the globe.These fittings have been installed on the outsideof the buildings and used in place of a spotlightor other fitting. Customers experienced theproblems during heavy rain experienced onoccasions recently.ESV urges RECs and LEIWs who install thesetype of fittings on the outside of buildings toreconsider this method and instead adoptthe requirement of Clause 1.6 of AS/NZS3000:2007, which covers the design of theelectrical installation, and ensure that any lightfitting installed on the outside of buildingsfunctions correctly as intended.

26www.energysafe.vic.gov.aucontents.electricalconnectionsfor gasappliancesMost domestic-type gas appliances relyon electricity to function. They aregenerally supplied with a power cordand 10 amp three pin plug. A power pointis required adjacent to the appliance.As well as providing the power supply, thismethod of connection serves as a pointof isolation, allowing the appliance to bedisconnected or serviced in a safe condition.It has been brought to ESV’s attention thatsome electricians are cutting off the plug andwiring the appliance direct to the supply. Theonly point of isolation may be at a switchboardremote from the appliance.This is in contravention of AS 5601-GasInstallations and the requirements of AS/NZS3000:2007, (Wiring Rules), in which Clause 1.7.1states:“1.7.1 Essential requirementElectrical equipment, forming part of anelectrical installation, shall be selected andinstalled to—(a) operate in a safe and reliable manner in thecourse of normal operating conditions; and(b) not cause a danger from electric shock,fire, high temperature or physical injury inthe event of reasonably expected conditionsof abnormal operation, overload, fault orexternal influences that may apply in theelectrical installation; and(c) be installed in accordance with themanufacturer’s instructions.”Some dual-fuel cookers (e.g. gas hotplate andelectric oven) do have power ratings requiringdirect wiring. It is a requirement of AS 5601,AS/NZS 3000:2007 and the manufacturer’sinstallation instructions that an acceptablemeans of isolation be provided adjacent tothe appliance.The publishers and marketers of the new WiringRules, SAI Global, have arranged a series ofhalf day seminars on the new Wiring Rules forAustralia’s capital cities and major regionalareas. The seminars are scheduled to run forfive hours, commencing at 1 pm.Members of the Wiring Rules EL-001 Committeewill be presenting at the seminars.

And this particularexample comes from the roof of a café!Mick is of course our “new face” of electricalsafety appearing in the ESV commercial whichurges the community to always use a licensedelectrician and demand a certificate of electricalsafety when the job is finished.The dangers of poorly installed halogendownlights has been a major issue in recentmonths with both the Minister for Energy andResources, Peter Batchelor, and ESV issuingwarnings about them. They pose a fire risk ifinstalled close to structural timber or becomecovered by insulation and ceiling debris.As reported in recent issues of energysafe,the new Wiring Rules (AS/NZS 3000:2007)cover the question of installing downlights muchmore explicitly than in the previous edition.Footnote: The commercial featuring Mick Dillema will be shownon television throughout Victoria as part of ESV’s nextpublic awareness campaign which will run for threeweeks prior to the Easter holiday.
