Ventilation in the general sequence of actions for a working structure fire is typically addressed...

• A. After safety and water supply have been established.
• B. Before size-up.
• C. Only after overhaul.
• D. Never used.

Answer: (A)

Ventilation is planned as part of the early tactical actions once you’ve ensured safety and secured a water source. Establishing safety and a reliable water supply sets the stage so you can ventilate without pushing the fire or smoke into areas where people may be, or where crews are operating. With life safety and containment in mind, ventilation then improves conditions inside by removing heat and smoke, clarifying visibility, and supporting both interior search and fire attack. It isn’t done before size-up, it isn’t reserved for overhaul, and it isn’t never used—ventilation is a coordinated, ongoing part of firefighting operations once initial safety and supply are in place.
