The particulars relied upon are similar for each charge:
(i) there was no proper risk assessment conducted for the work;
(ii) the work was performed when available measures at the premises to control the risk of the cabin collapsing were not adopted.
(iii) the conduct of the work on the vehicle with the cabin in a raised position supported only by the tilt stay bracket, without any secondary and external means of supporting the cabin, was unsafe; and
(iv) the defendant had no safe work procedure for the conduct of the work involving the release of tension from the torsion bar whilst the cabin was in a raised position, supported only by the tilt stay bracket.
4 An Agreed Statement of Facts was tendered relevant to both charges which reads as follows:
2. The partnership conducted its business which included the repair and maintenance of motor vehicles and farm machinery from its workshop premises at 11 Carrington Street, Crookwell in the state of New South Wales ( premises ).
3. On 15 July 2002 the worker and another employee of the partnership, Alan Collins, commenced work on a Ford Trader truck owned by McCarr's Wool ( vehicle ). The work involved the removal and fitting of new event cab mounts.
4. The vehicle had previously been in for service on 25 June 2002 but the job had to be postponed.
5. The vehicle was a tilt cabin type which required the cabin of the truck being tilted forward to enable access to the machinery beneath it.
6. The job was allocated to Alan Collins and the worker assisted him in the job.
7. Alan Collins at all relevant times was an experienced motor mechanic who held trade qualifications for about 30 years and who was experienced in working on trucks with tilt cabins.
8. The worker at all relevant times was an experienced motor mechanic who held trade qualifications for about 24 years. The worker was the leading hand mechanic for the partnership.
9. The job required that the cabin of the truck be tilted forward.
10. At all material times the raising of the cabin to the forward position was assisted by a balance spring device known as a torsion bar.
11. Whilst the cabin was in the raised position this torsion bar provided pressure to support it in such a position but there was an additional locking device known as a tilt stay. This tilt stay locked the cabin in the raised position.
12. In conducting the work of replacing the rubber cabin mounts it was necessary to move the bolts on the torsion bar mounts and on one of the flanges holding the torsion bar in place, in order to release the pressure on the torsion bar. Once the pressure was released from the torsion bar the tilt stay bracket took the full weight of the cabin to support it in the raised position.
13. At all material times on and prior to 15 July 2002 there was no specific instruction provided to the worker in relation to the requirement of independent support for the cabin of the truck in carrying out the task of replacement of the cabin mounts.
14. There were devices available at the premises which could have been used to independently support the cabin of the truck had the worker and Alan Collins chosen to use them. These devices included a wooden support bar, a tackle and chain and gantry crane. The defendant left it to the discretion of Alan Collins and the worker how they were to design the job.
15. Sometime around or shortly prior to 9.30am on 15 July 2002 the worker was under the front left hand side of the cabin, which was in its raised position. The worker was grinding a bracket or had finished grinding a bracket. Whilst the worker was in this position the tilt stay mechanism was released and the cabin was brought down onto the worker's body. The worker suffered an injury to his neck and has resulting permanent quadriplegia from his injury.
16. At all material times on and prior to the accident, having regard to the experience of the worker and Alan Collins, the defendant often allowed both men to design how they would carry out the automotive repair work for the partnership.
17. At all material times on and prior to 15 July 2003 the partnership had no documented procedure for the conduct of the work on tilt cabin trucks which required the use of independent or alternative support mechanisms to hold the cabin in a raised position whilst work was being carried out beneath it.
5 Each defendant pleaded guilty to the charge.
6 Mr R. Reitano, of counsel, appeared for the prosecution. Mr P.J. Cook, of counsel, appeared for the defendants. The prosecutor tendered a number of photographs of the site and a WorkCover Factual Report. Reliance was placed upon the Agreed Statement of Facts.
7 Mr Cook relied upon the affidavit evidence of Mr Noel Thomas Nicholson and Mr John Dean Thomas Nicholson. Documentation of worksafe systems and risk assessments designed for tasks within a mechanical workshop were also tendered. Much character evidence in support of both individual defendants were placed before the court.
8 Nicholson Farm Machinery conducts a business selling and servicing all types of farm machinery and farm vehicles. It operates in Crookwell, a beautiful and historic country town in New South Wales, surrounded by rural farming and grazing properties. Over the years, the Nicholson farm machinery partnership has provided employment in the district to over 40 employees and, throughout those years, supported through to qualification 14 apprentices. There are six persons now employed in the business in either the mechanical or clerical fields. The partnership has a number of long term employees which, in itself, is a positive commentary as to the quality of the defendants as employers. The two senior mechanics in the business were involved in the incident. Mr Kitchen and Mr Collins were both long term employees - Mr Kitchen was employed by the partnership for 21 years and Mr Collins for 19 years.
9 It was Mr Collins who was allocated the job in question by the younger defendant, the son, Mr John Nicholson. Mr Kitchen was called upon to assist Mr Collins. They were changing the mounts on a truck's cabin. The cabin of the truck had to be tipped forward to allow access to the mounts.
