AI-generated summary

Maurice Bauer, aged 50, died from electrocution while working on electrical switchboard relocation at a residential construction site in Queensland. The employer, Mr Forsyth, made a deliberate decision to work 'live' (with power supply active) without disconnecting the mains supply at the electricity pole—a straightforward task achievable using a fuse extraction stick or ladder. No risk assessment was performed, workers were not warned of live working conditions, and exposed conductors were inadequately insulated with standard tape. Sharp conductor ends pierced the tape, causing arcing that energised the entire metal structure of the house to approximately 240 volts. Mr Bauer received a lethal shock (approximately 200 volts, 12.5 amps) while working beneath the house. The coroner identified multiple preventable failures: failure to disconnect power before work commenced (the primary cause), substandard conductor taping practices, inadequate training in proper insulation techniques, and absence of a formal risk assessment. Had the mains supply been isolated as standard practice requires, this death would not have occurred. The case highlights the critical importance of adhering to established electrical safety protocols, proper training in live work prohibitions, and the use of appropriate materials and techniques.

Contributing factors

  • decision to work 'live' without disconnecting mains electrical supply
  • failure to use fuse extraction stick or ladder to disconnect power at electricity pole
  • absence of risk assessment for live work
  • inadequate insulation of exposed conductors using standard tape only
  • poor quality of conductor taping allowing copper strands to penetrate insulation
  • arcing between live conductor and switchboard metal box
  • lack of warning to workers regarding live working conditions
  • inclement weather contributing to box door closing on cables
  • missing earth electrode connection
  • neutral conductor not terminated in switchboard box

Coroner's recommendations

  1. Safety Alerts should be issued as soon as possible after a death or serious incident has occurred at a workplace, regardless of whether detailed investigations are pending, to warn or remind those in the industry of workplace hazards
  2. Improved processes for investigations into workplace deaths, including consultation on coroner report templates and investigative methods between the Workplace Health and Safety Division and the State Coroner
  3. Development of industry-approved procedures for proper taping of conductors, including specific guidance in the Wiring Rules (Rule 3) on what constitutes an effective taped joint
  4. Institution or reinstitution of a requirement in the Wiring Rules that electrical tape manufacturers' packages indicate the relevant Australian Standard number to ensure use of certified tapes and discourage use of substandard materials
