Control measure
Provide ventilation

Control measure knowledge

Ventilation may help to improve a toxic or asphyxiating atmosphere. Ventilating a confined space can dramatically affect working conditions and increase the potential for survival.

The confined space environment should be assessed to establish the appropriateness and potential success of the available means of ventilation.

Strategic actions

Fire and rescue services should:
  • Consider providing equipment to ventilate confined spaces

Tactical actions

Incident commanders should:
  • Consider ventilating confined spaces to improve internal conditions
  • Isolate or limit all ignition sources before ventilating a confined space if flammable gases may be present
