Control measure

Isolate and lock out power supplies

Control measure knowledge

The owner or occupier, on-site engineers or maintenance engineers should be able to provide specialist knowledge. Where specialist knowledge is not available, crews may be able to identify instructions either on or near the machinery or locate emergency stop buttons to isolate the machinery.

Strategic actions

Fire and rescue services should:
  • Provide emergency responders with information and instruction on the importance of safe and effective isolation of power supplies to plant and machinery at rescue operations

Tactical actions

Incident commanders should:
  • Request advice from responsible person or engineer regarding isolation and lock out of power supplies
  • Ensure machinery and processes are isolated and locked out before starting rescue operations
