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. Safety in Action2008 will give you the opportunity to learn thelatest and stay up to date,” said John Merritt,Executive Director of WorkSafe Victoria.“Events like this expose you to a hub ofexpertise and information designed to helpyou keep your workers and business safe.”gas appliancesin residentialgaragesA number of conditions must be metwhen installing a gas appliance ina residential garage. 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.
