Defensive Strip Ventilation typically requires which resource?

• A. Need for Multiple Crews/Multiple Tools
• B. A single crew with limited equipment
• C. Only one firefighter
• D. No coordination

Answer: (A)

Defensive strip ventilation demands a coordinated, multi-resource effort. This tactic creates a controlled opening, usually a strip across a roof or wall, to rapidly vent smoke and heat and slow the fire’s advancement. Doing this safely and effectively isn’t a one-person job—it requires more than one crew to place and size the opening, manage the removal of roofing material, and coordinate with interior fire attack and exposure protection. Multiple tools are needed (saws, axes, pike poles, and other equipment) to perform the cut, control the debris, and keep the opening clear and safe for progress. A single crew with limited equipment can’t reliably execute all these tasks while maintaining overall safety and communication, whereas proper coordination across crews ensures the operation supports suppression goals without creating new hazards.
