Much of what was urged by Mr King was directed to showing that the worker who was killed knew of, and therefore ought to have avoided the exposed electrical connections. In one sense such a submission militated against the position of the defendant; the very purpose of the Act was to introduce safe working practices so that accidents are prevented. The Act was designed to protect against human errors including inadvertence, inattention, haste and even foolish disregard of personal safety as well as the foreseeable technical risks in industry.
12 An important corollary of this latter point is that an employer's instructions as to safety must be both sufficient and complied with by employees and other workers: see Riley v Australian Grader Hire Pty Ltd at [16]. Here, although both parties appeared to characterise the offence as a failure to maintain a system, the amended application for order is in different terms, namely, a failure to provide and maintain an adequate system of work, by which characterisation I take to mean a failure to have in place at the premises an adequate system of work. It is clear from the evidence tendered during the proceedings that the defendant had in place a system at the premises designed to ensure the safety of personnel involved in the loading and unloading operations of construction and demolition waste. In my opinion, however, this system was deficient. No formal risk assessment had been undertaken at the site in relation to traffic management and Mr Reisenleiter had not received any formal training. Moreover, as earlier observed, the defendant was aware of a risk of collision between heavy vehicles as evidenced by its investigation into the possibility of employing a yardman at the "Stop" sign to direct the traffic into the unloading area, prior to the offence.
13 All of these matters serve to highlight the seriousness of the offence, although I intend to take into account as mitigating the seriousness of the offence the actions of Mr Reisenleiter and Mr Smeekens, as well as the fact that the defendant had in place a comprehensive system, although deficient, designed to ensure the safety of workers at the premises involved in the loading and unloading of waste. The actions of Mr Reisenleiter and Mr Smeekens must, however, be assessed by reference to the deficiencies in the defendant's system. This is to be contrasted with circumstances in which a defendant has in place a system of safety which is adequate but a departure from the system by, for example, an employee, nevertheless operates to expose other persons to a risk of safety. In my opinion, it is to this latter set of circumstances that the remarks of the Full Bench in Riley v Australian Grader Hire Pty Ltd were probably directed. For these reasons, the actions of both Mr Reisenleiter and Mr Smeekens operate to mitigate the objective seriousness of the offence to a degree, but not to the extent contended for by the defendant. The material on sentence (which includes the submissions of the parties) indicates that in the case of Mr Smeekens, this was the first occasion in which he had driven the front end loader with the bucket raised. As regards Mr Reisenleiter, although he had apparently issued instructions to truck drivers to drive beyond the "Stop" sign without first advising the loader operator on prior occasions, this practice had not come to the attention of Mr Lawrence even though Mr Lawrence, at least four days a week, had spoken to both persons at some length about operations at the premises. He also undertook regular inspections. Nevertheless, it seems that Mr Reisenleiter's departure from the prevailing practice was not, on the evidence tendered during these proceedings, brought to his attention.
14 In addition, the defendant had in place, prior to the offence, a general safety management system, the details of which have been set out in an affidavit affirmed by Christine Hodgekiss, the defendant's NSW Compliance Manager. According to Ms Hodgekiss, the defendant developed its Safety Management System in response to audit assessments by WorkCover in 2000 and 2001, after which the defendant was granted accreditation as a "self-issuer" in May 2002. The system contains a risk management division comprised of a risk manager, occupational health and safety officers, an environmental officer and other co-ordinators who assist the divisional managers and site managers with safety issues, as well as the undertaking of site audits and reviews. The defendant also developed a computerised "company-wide" intranet system (known as the "Hippo Station") which provides for various safety procedures, operating standards, JSAs and a computerised compliance monitoring system. The existence of these systems prior to the offence which appears both comprehensive and accessible, also serves to mitigate the otherwise objective seriousness of the offence.
15 On the other hand a number of factors serve to increase the objective seriousness of the offence.
16 First, the risk to safety occasioned by the risk of collision of heavy vehicles was, at minimum, reasonably foreseeable, and probably foreseen. This latter point appears in any event to have been conceded by the defendant. The defendant was aware of the risk of collision, as earlier observed, but after giving consideration to the issue by entering into discussion with CRG about employing a yardman, the idea was abandoned. In any event, a formal risk assessment of traffic flow, had one been undertaken, should readily have identified the risk.
17 Secondly, the principle of general deterrence is of particular significance in the circumstances of the offence. This is so notwithstanding the defendant's submission that it should play a limited role. The submission is advanced on the basis that the defendant had in place, prior to the offence, a detailed safety system, including a system specifically tailored to the operation of loading and unloading at the premises. In support of the submission, reliance is placed on the first instance decision of Marks J in WorkCover Authority of New South Wales (Inspector Chaston) v Vaughn Constructions [2005] NSWIRComm 254 at [15]-[16] where his Honour observed generally that:
