4 The amended application for order particularised the charge under section 8(1) of the Act as, in essence, the defendant's failure to provide and maintain a safe system of work in relation to electric line work, in that it failed to ensure that all electrical lines were properly examined, tested, de-energised and isolated prior to anyone commencing work upon them.
5 I have heard submissions from the prosecutor and the defendant in relation to that amended charge. The evidence of the prosecutor constituted an agreed statement of facts, a factual report prepared by Inspector Evans, a bundle of photographs, and a certificate of prior convictions showing that between 1992 and 2003 the defendant - also formerly known as North Power and Northern Rivers Electricity - had six convictions ranging from $2,000 to $160,000. I will return to these matters in due course.
6 In relation to the Agreed Statement of Facts it is appropriate to set out its terms in substance:
...
2. At all material times Country Energy [ABN NO: 37 428 185 226] was a State owned corporation whose registered office is situated at 8 Buller Street, Port Macquarie in the State of New South Wales (defendant).
3. At all material times, the defendant was an employer and employed Brian Edwin Goss (Mr Goss) as an electrical line worker.
4. On 27 August 2003 Mr Goss was required to perform electrical line work at a property known as "Lyondale" on Coonamble Road, Gilgandra.
5. On 27 August 2003 a rural 22-kilowatt high voltage circuit was to be isolated at high voltage fuses 3211, tested, earthed, and short-circuited. Two crews were required to work on the high voltage circuit under access permits.
6. The first crew comprised Mr Goss and James Wood (Mr Wood), another employee of the defendant. Mr Goss and Mr Wood were required to:
(1) isolate the overhead high voltage spur line at high voltage fuses 3211;
(2) prove that the high voltage mains were de-energised; and
(3) earth and short circuit the high voltage mains on the load side of fuses 3211;
(4) issue access permit; and
(5) notify Country Energy network control of isolation/de-energising and issue of the access permit.
7. In addition to this task, Mr Goss and Mr Wood were to replace a defective high voltage cross arm on pole 16-402 which had previously been verbally reported as defective. The pole supported both high voltage and low voltage mains.
8. The second crew, consisting of Ross Coxhedge, Darrol Eason and Mark Colwell were to construct a new rural pole mounted substation approximately two kilometres further down the high voltage line.
9. As the two crews would be working remotely from each other, each worked under separate access permits and communicated between the crews via radio and the defendants network control.
10. The pole that Mr Goss and Mr Wood were working on contained two pairs of wooden cross arms approximately 1.5 metres below the top cross arm. These cross arms supported high and low voltage circuits and had four circuits connected to them via porcelain insulators.
11. A distribution pole located some distance to the south east of the pole held and electrical transformer mounted on it. The transformer was mounted between the top and second cross arms on that distribution pole.
12. Circuits from the top cross arm were connected to the transformer. Circuits leading from the transformer were connected to the circuits on the second cross arms.
13. A switchboard was also mounted on the distribution pole at a lower level.
14. Prior to commencing the work of replacing the cross arm on the pole, Mr Goss and Mr Wood switched the circuit breaker in the switchboard box into the "off" position. The switchboard box was then locked and danger tagged.
15. Mr Goss and Mr Wood then took a morning tea break.
16. At the end of the morning tea break, Mr Goss went up in an elevated work platform (EWP) and commenced some preliminary work in relation to the defected high voltage cross arm on the pole. At this time Mr Wood was constructing the new cross arm. After a short period of time, Mr Goss returned to the ground in the EWP and asked Mr Wood to assist him. Mr Goss and Mr Wood then went up in the EWP to the area of the cross arm on the pole. Mr Goss exited the EWP and supported himself on the pole by means of a harness. In the course of the cross arm being replaced, Mr Wood had his back to Mr Goss when he heard a sound. Mr Wood turned around and saw one of Mr Goss' hands clenched on the low voltage line. Mr Wood prised Mr Goss' hand free with a stick and descended the EWP. Upon arriving at the ground Mr Wood immediately attempted to resuscitate Mr Goss. Mr Goss was later declared dead on arrival at Gilgandra Hospital.
17. A documented risk assessment was undertaken at the site prior to work commencing. In the documented risk assessment the hazards identified were:
- elevated work platform
- working at heights
- low voltage mains
18. The control to be put in place for the low voltage main hazard was noted as "isolated via c/b (control box)" locked plus + dt (danger tagging) attached, tested dead."
19. Mr Goss and Mr Wood signed the risk assessment.
20. After the incident it was established that the low voltage 3 phase mains at the work site had remained energised.
21. While the circuit in the switchbox had been isolated, another low voltage circuit in the transformer on the distribution pole had not been isolated. Switching off the circuit breaker in the fuse box switch did not de-energise the low voltage circuits fed from the transformer on the distribution pole. This was because the low voltage circuits had been hard wired into the transformer.
22. The low voltage circuit on the load side of the transformer was "hard wired" into the transformer. To de-energise the low voltage lines hard wired into the transformer, it was necessary to de-energise the low voltage circuit at the transformer which may have been done by either removing the transformer's high voltage fuses or by physically disconnecting the low voltage circuit where it connected to the transformer. This would have completely isolated those low voltage circuits.
23. "Hard wired" circuits is not uncommon on multiple low voltage circuits. As a result, the defendant's code of practice, Electrical Safety Rules CEK8030 provided, at rule 4.3, in relation to work on or near de-energised low voltage exposed conductors, that before work is commenced those conductors were required to be identified, isolated and proved de-energised. That rule was not complied with at the work site in that the low voltage circuits on the pole had not been isolated and all the low voltage circuits had not been tested to check that they were de-energised, before the work commenced .
7 The evidence for the defendant was constituted by an affidavit of Mark Andrew Mulligan, who was the chief safety officer of the defendant. His affidavit was extensive and there were four volumes of material accompanying the affidavit and constituted much of the records of the system of occupational health and safety implemented by the defendant.
