What is the ventilation rule for aircraft fires?

• A. Ventilation is optional and may be done as desired.
• B. Ventilation and interior attack must be planned/coordinated; initial ventilation can be opening doors and hatches.
• C. No ventilation should be attempted.
• D. Ventilation must be conducted only after charges are set.

Answer: (B)

Ventilation is an integrated part of fighting an aircraft fire, not a separate, optional step. The best practice is to plan ventilation together with the interior fire attack so crews work with a coordinated strategy. Opening doors and hatches as an initial ventilation action creates a controlled flow path for smoke and heat, which lowers temperatures in the space, improves visibility, and helps rescuers and attackers move more safely and effectively.

Coordinating ventilation with the attack prevents pushing flames or toxic gases toward personnel or into unvented areas and avoids unwanted backdraft or flashover scenarios. In an aircraft with multiple compartments, this teamwork ensures the ventilation changes support the fire attack rather than hinder it.

So, the correct approach is to plan ventilation and interior attack together, with initial ventilation often taken as opening doors and hatches to establish a safe, directed flow path.
