8 The Agreed Statement of Facts are as follows:
(1) On 31 May 2000, the Defendant employed Mr Michael Rykee ("Rykee"), (a 19 year old apprentice carpenter) and Mr Shannon Dallas ("Dallas"), (a 22 year old carpenter) at the site. As at 31 May 2000 ("the accident date"), Dallas had been employed by the Defendant for approximately four (4) years and Rykee had been employed for approximately twelve (12) months.
(2) On the accident date, there were four (4) carpenters employed by the Defendant working at the site. Those employees were Mr Phillip Denton ("Denton"), Mr Michael Cormack ("Cormack"), Dallas and Rykee. At all material times, Denton was the director of the Defendant. On the accident date Denton was acting as supervisor for Dallas, Rykee and Cormack. Dallas was acting as leading hand. Cormack was a second year apprentice.
(3) On the accident date, Rykee, Dallas, Denton and Cormack were all involved in the process of erecting roof trusses on top of the wall plates of the wall frames of the building under construction at the site. Prior to the accident, Dallas and Rykee had accessed the top plate of the wall via a seven (7) foot step ladder, and had walked along the top plate of the wall frames to erect the roof trusses.
(4) On the accident date, and prior to the accident, Rykee, Dallas, Denton and Cormack had erected and fixed the truncated girder truss on to the building under construction at the site. Two (2) end J1 jack trusses had also been positioned and fixed, as had two (2) hip trusses. The junction of the truncated jack and hip trusses had been fixed by nails at the top chord of the truncated girder truss. The first truncated truss (TS1) had been stood up and fixed to the top plates and the hip rafter. The truncated trusses TS2 and TS3 had not been fixed off, but were being held by Rykee and were in the process of being fixed off.
(5) Immediately prior to the accident, Dallas was sitting on top of the first truncated truss (TS1) and was pulling the top chord of the hip truss towards him when the truss he was sitting on fell over, causing him to roll backwards and fall to the concrete floor slab below. Dallas fell a distance of approximately 4.3 metres to the ground below. Dallas received a cut to his head requiring nine (9) stitches, and a T-12 spinal injury resulting in Dallas becoming a paraplegic.
(6) Immediately prior to the accident, Rykee had been standing on the top plate of the internal wall holding up the trusses (TS2 and TS3) for Dallas to fix off. The falling trusses struck Rykee on his right shoulder forcing him sideways. Rykee managed to use his left hand to catch the next set of roof trusses lying on the top plate to prevent himself from falling. Rykee then jumped down on to the concrete floor, and realised his right shoulder was severely dislocated.
(7) At the time of the accident, Denton was fixing a truss into the top plate of the wall frame. Cormack was standing on a step ladder facing away from the centre of the trusses and was drilling a truss into position.
(8) On the accident date, there was no system which prevented the Defendant's employees, including Rykee and Dallas, from being liable to fall from the position from which they were working whilst installing prefabricated timber roof trusses to the ground.
(9) Prior to the accident date, no formal risk assessment had been carried out by the Defendant in relation to the erection of the roof trusses at the site. A work method statement had not been prepared by the Defendant in consultation with its employees before they commenced work on the site. There was a plan as to how to construct the roof. This method was not written or formalised, but was the Defendant's standard operating procedure. The roof to be constructed at the site was a standard design roof and was built in accordance with the Defendant's informal standard procedure.
(10) On the accident date, there was no adequate system in place to ensure that the trusses were fixed securely so as to ensure that the trusses did not come loose or fall when the Defendant's employees applied pressure to them or rested on them while performing their duties. There were no "stand-up" joins for the trusses.
(11) Prior to the accident date, Rykee and Dallas had not undergone any occupational health and safety induction training.
(12) Following the accident date, the Defendant implemented new measures to ensure that the trusses were more secure and more strongly fixed during the erection process. New methods were used to train employees to check all points of securing the trusses, to ensure that extra blocks are used if fixing is inadequate and, to ensure that trusses are not straightened when it would be unsafe to do so.
(13) On 31 May 2000, the Defendant, being an employer at the said site, contrary to section 15(1) of the Occupational Health & Safety Act, 1983 (NSW), failed to ensure the health, safety and welfare at work of all its employees and, in particular, Mr Michael Rykee and Mr Shannon Dallas, in that:
(a) It failed to provide or maintain a system of work that was safe and without risk to health for the process of installing prefabricated timber roof trusses at the said site;
(b) It failed to provide such information, instruction and training as was necessary to ensure the health and safety at work of its employees and, in particular, Mr Michael Rykee and Mr Shannon Dallas, who were carrying out work at the site;
