Cause of death

electrocution from contact with energised electrical cable and metallic components in ceiling space

AI-generated summary

Dale Kennedy, a 3rd year apprentice electrician, died from electrocution while installing data cables in a school ceiling space. He was moving across wooden planks when his body weight pressed a cable (circuit 22) against a metal gang nail plate on a roof truss, penetrating the insulation and energising metallic components. Contact with an air-conditioning unit completed the circuit. Critical failures included: ESO inspectors focused narrowly on identifying the shock path without investigating why the cable was positioned dangerously across the gang nail plate; they missed evidence that a catenary support had been deliberately loosened, dropping the cable from its safe position; no investigation for similar hazards in other buildings occurred; and de-energisation of the workspace was not mandatory industry practice at the time. A comprehensive audit later found 111 electrical non-compliances across the school. An RCD (safety switch) would have prevented the fatality. The coroner emphasised systemic regulatory gaps and inadequate ESO investigation.

Contributing factors

  • cable (circuit 22) positioned across metal gang nail plate on roof truss without mechanical protection
  • catenary support saddle deliberately loosened, allowing cable to drop to unsafe position
  • power not de-energised in workspace before non-electrical work began
  • inadequate workplace electrical safety management and risk assessment
  • lack of RCD (residual current device) protection on circuit 22
  • cable not originally installed with adequate mechanical protection against disturbance
  • inadequate inspection and documentation of electrical work in ceiling spaces over building's operational life

Coroner's recommendations

  1. ESO reconsider various options for extension of mandatory RCD (residual current device) fitting requirements, including cost-benefit analysis, and circulate draft discussion paper to key stakeholders and public for consultation prior to finalisation of policy position or advice to State Government
