5. The Second Defendant leased premises at 396 Princes Highway, St Peters ( the Site ) and carried out the business of recycling depot at the Site receiving concrete and brick rubble and reprocessing it into quarry equivalent products ( the crushing operation ).
6. The First Defendant provided labour to the Second Defendant.
7. At all material times the First Defendant was an employer. The First Defendant employed Mr Hayden Birkett as leading hand/foreman. Mr Birkett was responsible for the crushing operation. The First Defendant also employed Haralambos (known as Harry) Sagiotis as a Demolition Worker Class 4 machine operator and Haralambos (known as Harry) Peros as a trainee.
8. At all material times the Second Defendant was an employer. The Second Defendant employed David McInnes as General Manager and the Third Defendant.
9. At all material times the Third Defendant had the role of overseeing the construction of the fixed crushing plant and the overall demolition techniques of the operation business of the First and Second Defendant.
Equipment
10. The crushing operation involved a Lokotrack crusher SN 465 1991 ( Lokotrack ) which was a mobile rock crushing machine. The Lokotrack was operated by an operator standing on a platform ( the service platform ) (see photograph 2 of 15B taken by Daryl Wong on 18 August 2001). Mr Sagiotis (now deceased) usually operated the Lokotrack.
11. An excavator, which was situated at the rear of the Lokotrack, loaded material onto a vibrating conveyor section of the Lokotrack (see photograph 3 of 15B taken by Daryl Wong on 18 August 2001 and photograph 2 of 10 taken by Ritchie Green on 18 August 2001). The excavator was operated by a person seated in the cabin of the excavator (see photographs 3 of 8 and 5 of 8 taken by Ritchie Green dated 23 August 2001).
12. The purpose of the Lokotrack was to crush/pulverise the material. The material to be crushed/pulverised by the Lokotrack on 18 August 2001 was sandstone.
13. The material was then conveyed towards crushing jaws of the Lokotrack by the in-feed conveyor. The crushing jaws crushed the material and the crushed material was then released onto a horizontal and inclined conveyor belt located beneath the crushing jaws. The conveyor belt then transported the material from beneath the crushing jaws and discharged the material onto a stockpile beneath the discharge end of the conveyor.
14. A loader operator then cleared the crushed material away from the Lokotrack by front end loader and stockpiled it.
15. There was a steel grate cover ( the rock grill ) to prevent stone chips from coming out of the crushing jaws. Depending upon the type of material to be crushed the rock grill over the crushing jaws remained open when the Lokotrack was being operated (see photograph 11 of 15B taken by Daryl Wong on 18 August 2001). The rock grill was open during the whole of the crushing operation on the day of the incident.
16. The Lokotrack operator would stand on the service platform of the Lokotrack and watch the material going along the conveyor and into the crushing jaws. The operator would lean over and pick rubbish from the material placed on the conveyor and in the crushing jaws (see photograph 6 of 6B taken by Ritchie Green on 21 August 2001 - with the rock grill down). The operator would use a pinch bar or hook.
17. The Lokotrack was manufactured in Finland by Nordberg (Locomo) OY. It was purchased in January 1993 from Nordberg (Australia) now known as Metso Minerals (Australia) Pty Limited.
18. The Second Defendant leased the Lokotrack from The Kouris & Peros Unit Trust.
Incident on 18 August 2001
19. On Saturday, 18 August 2001, Harry Peros and Harry Sagiotis commenced working at the Site at approximately 7.00 am. At about 9.00 am Mr Birkett directed Mr Sagiotis and Mr Peros to begin the crushing operation.
20. Mr Sagiotis operated the Lokotrack. Mr Peros operated the Excavator. Mr Danny Batt, loader operator, operated the front end loader.
21. The material being loaded onto the Lokotrack on 18 August 2004 consisted of sandstone material and reinforced concrete which contained pieces of reinforcement or steel.
22. During the morning there was a blockage on the Lokotrack when a bit of small reinforced concrete block was amongst the sandstone and bridged the crushing jaws. It was unable to be removed using the picking process.
23. Mr Sagiotis moved the Lokotrack around to face the excavator. Mr Peros removed the bucket from the quickhitch of the excavator. Mr Peros attached a chain to the excavator and the chain was lowered in. Mr Sagiotis leaned over the crushing jaws and attached the chain to the steel protruding from the footing. The crushing jaws were still operating. The rock grill was open on 18 August 2001. The footing was then lifted out by the excavator.
24. Mr Sagiotis and Mr Peros communicated by hand signals.
25. At about 10.20am Mr Peros placed a load of material on the Lokotrack.
26. Mr Sagiotis was last seen by Mr Peros standing on the service platform. The rock grill was in the open position and the crushing jaws were operating.
27. Mr Peros turned the excavator around to his right to pick up the next load and was facing away from Mr Sagiotis.
28. Mr Peros thought he heard a noise like someone yelling.
29. When Mr Peros again faced the Lokotrack he could no longer see Mr Sagiotis.
30. Mr Peros alighted from the excavator and checked to see where Mr Sagiotis was. In the area of the crushing jaws Mr Peros saw sandstone and the bottom of Mr Sagiotis' boot. There was approximately one and a half tonne of material compacted in the crushing jaws.
31. At the time the Lokotrack was still being operated. Mr Peros turned off the Lokotrack.
32. Mr Sagiotis' body was trapped between the crushing jaws. He suffered extensive crush injuries. When Mr Sagiotis was recovered from the crushing jaws he was deceased. The direct cause of death was upper airway obstruction and mechanical asphyxia.
33. Located in the crushing jaws was a pinch bar and a box section of steel, approximately 150mm square by 150mm in length, wedged between the crushing jaws.
Observations made following the incident
34. At about 10.30am on 18 August 2001 Inspector Ritchie Green attended the site with Senior Inspector Daryl Wong. Inspector Green and Inspector Wong took a number of photographs and Inspector Green prepared a Factual Inspection Report
35. Inspector Green issued three Notices to the Second Defendant.
36. On 28 August 2001 Mark Nugent, service representative for Metso Minerals Pty Limited, carried out a visual mechanical inspection of the Lokotrack whilst it was non operational. Amongst other things he observed the following:
(a) the service platform had been changed since the date of supply in that on top of the kick rail, which was fixed around the platform, a steel grate floor had been positioned. This had the effect of raising the working floor about 110 to 120mm from the original specifications;
(b) the standard hopper wall on both the right hand side and left hand side had been modified. Sections each side measuring around 600mm x 200mm had been torch cut out and then repositioned back on to the hopper walls at a different angle. This had lowered the hopper walls by about 100mm.
37. The height of the hopper wall was 700mm from the floor of the service platform to the lower edge of the hopper wall (splayed steel barrier) and 900mm from the floor of the service platform to the top of the splayed steel barrier.
38. From Inspector Green's observations he estimated that the modification to the wall referred to by Mr Nugent above produced an angle of 45 degrees.
39. The combined effect of the modifications to the steel barrier and platform decreased the vertical height of the steel barrier by approximately 254mm to the top edge, and 454mm to the lower edge of the splayed steel barrier. This facilitated a person leaning across to access the crushing jaws and increased the probability of falling over the barrier.
40. Operators were required to wear a safety belt and lanyard whilst operating the Lokotrack. The lanyard was attached to the rear guardrail of the service platform. This was to be used when the operator had to lean substantially over the wall and the feeder to remove material on the far side of the feeder. The operator used extension hooks and bars to remove material generally from the far side of the feeder. For blockages in the crushing jaws a bar would be used to move the obstruction or an excavator would be used for lifting.
41. Mr Sagiotis was not wearing a safety belt on 18 August 2001. Safety belts were on site.
42. The Third Defendant had on other occasions seen Mr Sagiotis working on the Lokotrack. If he was not wearing his safety harness the Third Defendant told Mr Sagiotis to immediately do so.
Steps Taken After the Incident
43. In response to the Improvement Notices the Second Defendant conducted a full risk assessment review of the operational procedures. Personnel involved in the operation of the Lokotrack were re-inducted on the risk assessments developed for safe operation and on new procedures to use mechanical means to clear blockages of the crushing jaws. Harness requirements were reinforced for working over the hopper.
