From the Legal DeskBy Stephen Tatrallyay, LLBEven one-minute jobsdemand safety precautionsIn June 2008, Madame Justice Simmonsof the Ontario Court of Appeal renderedher decision in R. (Ministry of Labour)v Bruno’s Contracting (Thunder Bay)Ltd.*—a decision on the scope of thedefence of “reasonable precaution” foundin Section 25(2)(h) of the OccupationalHealth & Safety Act (OHSA), and onewith which all contractors and subcontractorsand employers on constructionprojects should be familiar.The decision dealt with a worker whowas hit by a truck as it made a wide turnout of a scale area at a mill in ThunderBay, Ont. At the time of the occurrence,the worker was painting lines on thepavement in preparation for patching it.He was seriously injured, and charges werebrought against his employer, Bruno’s,under OHSA.The victim and a number of his colleaguesand superiors testified that theentire job was only supposed to takeabout 30 seconds to one minute. He wasan experienced worker; he had safety equipment withhim but, at the moment of the accident, was decidingwhere to put it.In section 25(2)(h), OHSA provides a defence to theeffect that employers are only liable when they do not“take every precaution reasonable in the circumstancesfor the protection of the worker”. Bruno’s relied onthis section in arguing that it was not a “reasonableprecaution” to require the use of safety equipment onsuch a tiny job.Both the original justice who heard the charge andthe Provincial Offences Judge at the first level of appealfound that Section 67 of the Construction Regulation<strong>Electrical</strong> testersEarth groundclamp metersRugged and reliableelectrical testingproducts.All in the Fluke family.<strong>Electrical</strong>MultimeterInsulation testersDon’t get burned.Find it.

The Provincial CourtJudge at the first level of appeal agreed and, in addition,found that it was a reasonable precaution to have asafety plan in place on any occasion—no matter howbrief—where a worker is required to perform his jobin a trafficked area.Bruno’s applied to the Court of Appeal for leave toappeal this decision. The motion for leave to appealwas heard by Mme. Justice Simmons, sitting as a solemember of the court. In addition to adopting thefindings of the lower court judges, she pointed outthe evidence that this was an extremely busy pulp millwith extensive truck traffic in the area where the workerwas injured. Given that, it was appropriate to have andimplement a traffic protection plan, even though thejob was expected to be completed very quickly.Justice Simmons had no regard for the defence thatit was impractical to require such extensive preparationfor a very minor job, nor that requiring such preparationswould negatively impact the industry. Shereviewed the standards for granting leave: a) specialgrounds; b) a question of law alone; and c) in theparticular circumstances it is essential in the publicinterest or for the administration of justice that leavebe granted. Using that very high threshold, she heldit was inappropriate to grant leave. She refused to doso, thereby putting an end to the matter.NOTE* [2008] ONCA 495.”Stephen Tatrallyay is a prominent Toronto Construction Lawyerand one of the members of Team Resolution, which providesneutral, third-party expertise and input aimed at resolvingdisputes outside of the courtroom (www.teamresolution.ca).A member of EB’s Editorial Advisory Board, he can be reachedat (416) 482-5164 or via e-mail at statrallyay@rogers.com.Fluke_EB_Feb08.indd 118 • NOVEMBER/DECEMBER 2008 • www. mag.com1/16/08 2:26:39 PM
By Dave SmithMIND YOUR SAFETYMeeting the new CSA Z462 standardThe final draft of CSA’s much-anticipated standard onworkplace electrical safety, Z462, is complete; it willbe available in January, though there’s still a greatlack of understanding surrounding this standard.First, a little background: the Canadian StandardsAssociation creates standards for Canadians. Havingthis national body for writing standards meansindividual provinces/territories need not have theirown standards-writing bodies. CSA writes standardswith input from all Canadians, then makes thempublicly available on a cost recovery basis.CSA has no legislative powers; its standards arevoluntary. Provinces and territories (and companies)choose whether they wish to adopt them. For instance,it has been standard practice for decades that eachjurisdiction adopt the Canadian <strong>Electrical</strong> Code(C22.1-06, Part I, Safety Standard for <strong>Electrical</strong> Installations).Other standards—especially new ones—arenot automatically adopted.seems simple enough until you learn thatCategory 0 requires cotton clothing—nopolyester blends, which are outside thestandard. For example:A worker goes to reset a breaker that hastripped due to the poor use of a chop saw,and the panel flashes during reset.If his overalls ignite, he’s off to the burncentre; you’re outside the standard, andauthorities will conclude you haven’t met thespecific duty clause. Good luck in court.And even if your jurisdiction does notyet have a specific duty clause relatingto arc flash or flashover, it is guaranteedto have a general duty clause, which useswording like “The employer shall protectworkers from all recognized hazards”. Arcflash and flashover are now very well-recognizedhazards and, in the example above,you would still find yourself in court.An electrician is voltage testing a 600V disconnect.He must be protected to HRC 2*.If you do not know what this means, you’reoutside the standard. You’d better hope ameter lead does not slip off a lug, or elseyou’ll find yourself in court again.The bottom line is you have to protectyour workers, and the only way to protectthem from arc flash or flashover is byadopting CSA Z462 as your minimumstandard. It is the best risk managementyou’ll ever employ to protect your electricaland other workers. Should you choose notto adopt it, then you may as well cancelthat fire insurance you have on yourhouse... you’re less likely to experience ahouse fire than an industrial accident.Until next time, be ready, be careful andbe safe.Dave Smith is president of Canada TrainingGroup and has been providing consulting servicesto industry since 1980.

Herein laythe problem: many people believe that, unless Z462is officially adopted, no one has to follow it.This is a major misconception: in numerousCanadian jurisdictions, safety legislation statesemployers must protect their workers from arc flashor flashover. The wording may change, but the legislativeintent does not. This is referred to as a specificduty clause. When your company operates in a jurisdictionwhere this wording is found in the legislation,then Z462 is not optional. The final defence for protectingyour workers from arc flash or flashover is PPE(personal protective equipment), and the only way todetermine appropriate PPE is by following Z462.There are two methods for determining PPE withinZ462. The first, Clause 4.3.3.3.2, describes “Method1: Selection based on incident energy analysis”, whichis also known as conducting an arc flash hazardanalysis. This has at least six parts to it:1. Conduct a short-circuit study2. Conduct a co-ordination study3. Take the results from these and conduct the arcflash hazard analysis4. Put labels on all of your equipment describingthe arc flash hazard at that equipment5. Purchase the PPE that will protect yourworkers at that equipment6. Train your workers to understand the labelsand correct PPE use.Looks simple, right? Wrong. $10,000 doesn’t go veryfar, and one northern mine is looking at a $2.5-millioninvestment. A major city transit system figures it mighttake about five years to complete its study.A less expensive—though not as precise—method isto have your workers follow the ‘Task Tables’. Clause4.3.3.3.3 describes “Method 2: Selection based onhazard/risk categories”, which refers you to Clause4.3.7.3.9 “Selection of personal protective equipmentfor various tasks”.These tasks are listed in Table 4 “Hazard/riskcategory classifications and use of rubber insulatinggloves and insulated and insulating hand tools”.Further complicating the mix is that the Task Tablesare limited to systems with short-circuit and protectivedevice parameters that are known to be under a certainlimit. When the system is beyond that limit, Clause4.3.7.3.9 requires an incident energy analysis.Until then, Table 4 lists common tasks performedon electrical equipment. For example, operating a120V, 15A breaker is a Hazard/Risk Category 0 ThisReduce cost and downtime whileincreasing safety and flexibilitySquare D ® Brand MD50Motor Disconnect SwitchThe Square D ® brand has been an industry leader in safetyswitches for over 100 years and is recognized as the marketleader in quality, durability and product development.
