Control measure

Intervention plan: Underground structures

Control measure knowledge

Confirmation should be sought from the infrastructure managers on the status and operation of systems used to protect members of the public, staff and firefighters, for example:

  • Ventilation systems
  • Pressurised escape area or intervention shafts
  • Vehicle control systems (for example road traffic lights set to red at either end of tunnel)
  • Current status of high voltage electricity.
  • Use of any of the infrastructure manager's rescue or recovery teams
  • Use of survivor reception centres and staff or customer support systems.
  • Suitability of equipment to function in a tunnel or underground environment
  • Communication facilities for subsurface operations

Strategic actions

Fire and rescue services should:
  • Develop pre-planned intervention strategies for underground environments identified as risk within the service area.

Tactical actions

Incident commanders should:
  • Carry out a risk assessment of the intervention options before implementing the most appropriate strategy

  • Co-ordinate the evacuation, ventilation, fixed installation and intervention strategies simultaneously
