Engineering implications of the harmonised safetylegislation by RichardRobinson he implications of the new model Work Health and Safety Act will forcefullychangethe way Australian businesses andgovernmentsoperate. The act is aimed at corporategovernance. It requiresthe most senior decisionmakâ‚Źrs (exceptinggovernment ninisters) to positively demonstratedue diligence for the safeq hazardscreatedby their business or undertaking. The penalties for recklessfailure to achievethis duty are criminal in nature (up to five years'jail and $600,000fine). Philosophically,the act adopts the Iegal view of causation,which necessarily is hindsighfbiased. By their nature, the courts only examine the minority of things that went wrong, not the majoritf of things that went right. That is, after the event,the fact is certain. This means

that, from the courtt viewpoint, prior tothe-event estimatesof rarity for serious loss eventswere presumablyflawed and thosewho madesuchestimatesare,pima facie,guiltyof negligence. Historically,due diligence is the primary defenceagainst common law negligenceclaims. The obligation under the act is for officers to positively demonstrate due diligence. This would appear to create potential opportunifies and difficulties for engineers. As an opportunity, it should increase the need for technically competent directorsand execulivesfor technologically basedbusinessesand undertakings. The notion of a mining company board comprised exclusively of legal and finance directors who have never beerr underground, and whose knowledge of

scienceand engineeringis insufficient to comprehendthe hazardsassociatedwith such an undertaking will be eliminated. This shouldprovide greateropportunities for engineersat the most senior levels,as the duty cannot be delegated. That is, under the act, boards can no longer decide on the bâ&#x201A;Źst commercial course of action and then delegatethe responsibility of safely achieving these outcomes to managers,and health and safetyadvisers.One of the lawyers who helped draft the act has been reported as saying that, if board members can not positively demonstrate that safety due diligencehas been achievedin their company'soperations,then the intention of the act is the company should not be in business.How such an idea might be applied to governmentdeparlmenl. is perplexmg.
