Extent of harm caused or likely to be caused by the offence
72The EPA submitted that the objective harmfulness of the Defendant's actions were relevant to determining the seriousness of the crime per Bentley v BGP Properties Pty Limited [2006] NSWLEC 34; (2006) 145 LGERA 234. In this case that is adverse impact on road users, the general public and the broader environment. It includes the potential or risk of harm per Axer Pty Ltd v Environment Protection Authority (1993) 113 LGERA 357. No actual harm was caused by the offence but there was potential for harm.
73The dangerous goods that are the subject of these proceedings were Class 8 dangerous goods, being substances which, by chemical action, cause severe damage when in contact with living tissue, or, in the case of leakage, will materially damage, or even destroy, other goods or the means of transport (SOAF, par 54). As set out in the SSOAF, the six IBCs containing sodium hydroxide in Trailer A were not restrained in accordance with the requirements of Part 8 of the Regulations, which incorporates the requirements of Part 8 of the ADG Code. The ADG Code in turn requires compliance with the Load Restraint Guide (prepared by the National Transport Commission and the Roads and Traffic Authority of NSW, 2nd edition, 2004 (SSOAF, par 4).
74Although the IBCs in Trailer A were behind vertical side gates and a rope was tied across the gates, this was clearly inadequate to restrain the load. The rope was not in contact with the top of the IBCs. Adequate restraint of the IBCs would have involved the application of force to the top of each IBC in an amount of at least 20 per cent of the weight of each IBC (see p 21 of the Load Restraint Guide), for example by the use of webbing straps (SSOAF, par 4).
75The purpose of having accurate placards and EIPs in prominent places on a vehicle transporting dangerous goods is to warn other road users of the risks relating to the vehicle's load, and to ensure that emergency response personnel are readily able to determine the most appropriate action to take in the event of an emergency. In the event of an accident involving the vehicle, the contents of the load would not have been immediately apparent to emergency personnel. This had the potential to delay any emergency response whilst the nature of the dangerous goods on board the vehicle was identified.
76The Defendant asked the Court to take into account that IBCs are a type of container defined under cl 15 of the Regulation to meet particular structural and design specifications set out in Chapter 6.5 of the Code to meet the objective of safe transport. The Defendant asked the Court to note that where dangerous goods are transported in IBCs, different requirements for transporting apply where the amount transported is 3,000 litres or less. In that case no licensing of the vehicle or driver is required (cl 189 of the Regulation). The Defendant accepts that 6,000 litres of sodium hydroxide were being transported and that placarding requirements applied regardless of how much was transported in IBCs. I note however that not all the dangerous goods the subject of the charge were in IBCs.
77The EPA's submission that the failure to safely secure the six IBCs of sodium hydroxide increased the risk of human injury or death and increased the risk of environmental harm in the event of an accident was disputed. The Defendant disputed the EPA's submission that as the IBCs each weighed about one tonne and were not secured in accordance with the Regulation there was an obvious risk of these toppling out of the vehicle if it travelled at speed or had to brake sharply, thereby posing a risk of severe injury to any people nearby. The IBCs were in separate cages and stored at the front of the truck next to the gate. There is no evidence adduced to support this and as the Defendant submitted it is not an element of the offence accepted as a result of the guilty plea. Without evidence which establishes these submissions beyond reasonable doubt per R v Olbrich [1999] HCA 54; (1999) 199 CLR 270, the EPA cannot rely on these matters. The Defendant's submission that it accepted there was a theoretical risk of injury resulting from the offence, but no actual risk was proven, is accepted.
