A labour hire company cannot escape liability merely because the client to whom an employee is hired out is also under a duty to ensure that persons working at their workplace are not exposed to risks to their health and safety or because of some alleged implied obligation to inform the labour hire company of the work to be performed. In our view, a labour hire company is required by the OH&S Act to take positive steps to ensure that the premises to which its employees are sent to work do not present risks to health and safety. This obligation would, in appropriate circumstances, require it to ensure that its employees are not instructed to, and do not, carry out work in a manner which is unsafe.
16 It follows from the foregoing summary of the evidence and the relevant authorities on the point that Deno's Cranes must share some of the overall culpability for the conduct to give rise to the offences. Having said this I do not agree with the submission made by the first defendant during the sentence proceedings that it's role was "very minor". The prosecutor submitted that the respective culpabilities of the two defendants were objectively indistinguishable or at least difficult to separate. The first defendant with the requisite expertise in scaffolding had particular control of the task of relocating and dismantling the scaffolding but the first defendant as principal contractor had overall control of the site. On the other hand as I have found, the second defendant had in place prior to the offence a system of safety for all contractors at the site. This system was comprehensive, and, by all accounts, adequate. The prosecutor described the system as "laudable". Nor could the system be described as a mere paper system. Instead, it was successfully implemented at the site in relation to both employees and contractors. According to the affidavit of David Moffat, the second defendant's construction director, prior to Mr Murdock's accident, 68 workers had been inducted at the site. This number represented all workers on the site with the exception of the three members of the crane crew. In my view the existence and operation of this system at the site makes the objective culpability of the second defendant less than that of the first defendant. As to Deno's Cranes it had a significant role as Mr Murdock's employer and, on the facts was capable of making appropriate enquiries to ensure the crane crew undertook the task it was assigned safely. I intend to take the culpability of Deno's Cranes into account when sentencing both defendants.
