5 An agreed statement of facts was tendered by the prosecutor, annexing the following documents:
(i) plans of the accident scene;
(ii) diagrams of the relevant machinery;
(iii) photographs of the work area, pump station, glass jars placed at the pump station, hose and connection point, heavy duty shifter, simulation of extraction of staple, overview of equipment at the pump (ball valve, lock out plates, staple, straight swivel female to BSPP male, dowty washer and elbow adaptor);
(iv) CENT Service Site Report dated 26 June 2006 and signed by the deceased;
(v) Department of Industry & Investment: Certificate of Prior History recording no prior convictions under the relevant occupational health and safety legislation; and
(vi) WorkCover New South Wales: Certificate of Prior History recording no prior convictions under the relevant occupational health and safety legislation.
6 In addition, the prosecution adduced into evidence a DVD, which was viewed by the Court. The DVD was filmed after the incident, and ran for some three minutes. The scene was of the area in which the incident occurred, displaying the conveyor belt and pump in the room. The footage provided a close up view of the pump station and various parts contained therein. Mr Agius SC for the prosecutor, highlighted significant aspects of the footage as it ran, such as pointing out the fitting, block, passage for hydraulic fluid, hose and its connection to the fitting and the staple sliding into the fitting to affix it to the block. Mr Agius stated that the lighting in the footage was artificial for the purposes of visibility; however, the area would have much darker at the time of the incident. Nevertheless, Mr Hansen would have been assisted by a helmet light and other lighting in the area and the Court is satisfied that poor lighting did not contribute to Mr Hansen's death. The prosecution adduced a replica of the incident fitting into evidence. The fitting had attached a metal staple.

8 Mr Hansen was employed as a service engineer by the defendant and had worked for the company since January 1997. He commenced work in the coal mining industry in January 1985. The defendant supplies oil products and related services including raw 'Solcenic 2020' hydraulic oil to collieries in New South Wales. At the time of the incident, the defendant had contracted with Centennial Coal to supply oil products, including solcenic emulsion, and services used in relation to the operation of hydraulic equipment in its longwall operations at Angus Place colliery, as well as other collieries operated by that company. Part of the contract involved the regular taking and analysing of samples of the solcenic emulsion contained within the hydraulic system, including within the pump station (which could be affected by dirt and bacteria), the purpose of which was to test the quality of the fluid and allow for the monitoring of the performance of the filters at the pump station. The role of service engineer required, in part, Mr Hansen to take samples from hydraulically operated plant at various underground mines. The role also required Mr Hansen to provide technical advice, including 'trouble shooting' on the hydraulic plant he serviced as part of his duties.
9 The agreed facts described the circumstances leading to the death of Mr Hansen:
· At approximately 2.45pm on Wednesday 26 July 2006 Mr Hansen entered the Angus Place Colliery in order to take the monthly samples. At about 3.00pm he travelled underground with the afternoon shift crew. On arrival at the Longwall Mr Hansen collected three solcenic emulsion samples from chocks at the face line of Longwall 930.
· Mr Hansen then walked from the face line to a location known as cut-through number 9 of the 930 Panel, where the Pump Station was located. This was approximately 482 metres away (outbye) from the operating Longwall face line.
· Mr Hansen had with him at that time, inter alia, three labelled bottles used to sample fluid from the Longwall chocks plus a further five empty, labelled sample bottles to be used to contain fluid to be taken from the Pump Station.
· Mr Hansen was at this point working alone without supervision.
· At approximately 4.l4pm the Pump Station, which was running, suffered a sudden loss of pressure consistent with a fitting being opened releasing pressurised fluid.
· The Pump Station ran for approximately 40 seconds after the sudden loss of pressure before automatically shutting down as a result of sustained hydraulic oil pressure loss in the system.
· At about 4.30pm the Afternoon Shift Maintenance Crew Leader, John Sheehan, an employee of Centennial Angus Place, entered the number 9 cut-through to investigate why the Pump Station had shut down. He found Mr Hansen lying on the ground adjacent to the delivery end of the Pump Station. Mr Hansen had severe facial injuries; he had no pulse and did not show any sign of breathing. A 375mm shifter was located nearby.
· Placed on the Pump Station adjacent to where Mr Hansen lay were three empty sample bottles labelled "Post HP Filter", "Bulk Tank", and "Mixing Unit". Also on the Pump Station was a bottle labelled diluent water containing already sampled fluid. Mr Hansen's bag contained inter alia three labelled bottles containing fluid taken from the Longwall chocks; namely the maingate support, mid face support and tailgate support samples. It also contained a labelled bottle containing the return line sample apparently taken from the Pump Station.
· Directly adjacent to where Mr Hansen lay was an open fitting between the high pressure delivery manifold and the system pressure drain line, where a straight swivel female to BSPP male (Part No PS115-10-06) had been connected to a swivel male female 90° elbow (Part No Ps76-10) ("the Incident Fitting"). The Incident Fitting was of a type that was opened by the removal of a 10mm staple.
· When the Pump Station was operational and at full pressure, as it was at 4.14pm on 26 July 2008, upon that fitting being opened by removing the staple, solcenic emulsion fluid pressurised to 305bar would have been ejected at approximately 200 metres per second or 720km per hour, reducing to about 160 metres per second after approximately 60 seconds.
· Mr Hansen suffered a serious injury to his face consistent with being struck in the face by solcenic fluid at high pressure while his face was in the trajectory of the ejecting fluid. Immediately above the Incident Fitting there was found a 50mm deep hole in the roof 2.6m above the Incident Fitting consistent with high pressure solcenic fluid being released and hitting the roof.
· There were no eye witnesses to the event.
· It appears that Mr Hansen's death occurred as a result of him using the shifter to remove the staple from the Incident Fitting whilst the Pump Station was operating. Upon the staple being removed the Incident Fitting would have separated under high pressure causing the emulsion fluid to eject straight up striking Mr Hansen in the face and killing him. The force necessary to remove the staple from the Incident Fitting whilst the Pump Station was under full operational pressure was found to be well within the forces a person could exert. The required force to remove the staple would not have been so great as to be likely to indicate to Mr Hansen that the system was in fact under pressure.
· It appears Mr Hansen removed the staple from the Incident Fitting in order to obtain the bulk tank and/or the post HP filter samples. On an earlier occasion Mr Sheehan had observed Mr Hansen removing a staple from another similar fitting attached to the same hydraulic line close by to obtain a bulk tank sample. That similar fitting was not under pressure. It would appear that on 26 July 2006 Mr Hansen opened the Incident Fitting by mistake.
· Prior to 26 July 2006 Mr Hansen had taken the monthly samples from the Pump Station on six occasions commencing on 9 January 2006.
· Fuchs required Mr Hansen to obtain the following monthly samples from the longwall hydraulic system:
a. Five samples from six different locations on the Pump Station, namely:
i. Diluent water;
ii. Post HP filter;
iii. Mixing unit;
iv. Bulk tank;
v. & vi. Return line (pre-return line and/or post-return line); and
b. Three samples to be taken from the longwall chocks namely:
vii. Maingate
viii. Mid face.
ix. Tailgate.
10 The prosecution submitted that Mr Hansen perhaps had in mind to take a sample. He removed the staple from the high pressure end. With the intense pressure in the system, the removal of the staple resulted in the fitting coming apart. There was then nothing to retain the pressure fluid, as it rose up in a column and fatally injured Mr Hansen.
