Cause of death

Hypoxic ischaemic cerebral injury secondary to respiratory arrest in the setting of chemical fumes

AI-generated summary

Karl Harrison, a 69-year-old man with expertise in chemical products used for slate floor restoration, died from hypoxic ischaemic cerebral injury following respiratory arrest caused by exposure to dichloromethane fumes. Working alone in a poorly ventilated basement, he removed his mask and the ventilation fan was unplugged when he collapsed. He had previously survived a similar incident in 2004 where he was overcome by fumes. The coroner found multiple preventable safety failures: inadequate ventilation in a confined space, use of a product labelled for outdoor-only use, working alone without respiratory protection, and minimal supervision by the contractor despite known hazards. The European Union banned dichloromethane in paint strippers in 2012, the year of his death. Clinical lessons include recognition of toxic exposure hazards and the critical importance of engineering controls and respiratory protection in confined spaces with chemical hazards.

Contributing factors

  • Exposure to dichloromethane fumes from NuStrip paint stripper
  • Poorly ventilated basement with no windows or external vents
  • Working alone without adequate respiratory protection
  • Removal of protective mask during work
  • Unplugging of ventilation fan
  • Use of product intended for outdoor use only
  • Minimal supervision by contractor despite known hazards
  • Previous chemical exposure incident in 2004 did not result in systemic safety changes

Coroner's recommendations

  1. Highlighted the serious hazardous nature of dichloromethane and the need for stringent work practices
  2. Drew attention to the European Union ban of dichloromethane in paint strippers from June 2012
  3. Noted the need for improved supervision and risk assessment by contractors when engaging workers with hazardous substances
  4. Implied need for enhanced safety protocols beyond minimal contractor oversight, particularly for known hazardous substances
