What is a critical safety consideration when using PPV?

• A. The rapid deployment of water through the structure using high pressure
• B. Ensure doors and windows are closed to contain the fire
• C. Ensure doors and windows are controlled and occupants and responders are warned to avoid blowing fire toward them
• D. PPV should only be used on exterior openings

Answer: (C)

PPV works by pushing air through a structure, which can dramatically affect how the fire and heat move. The most important safety step is to control every door and window that the ventilation plan uses and to warn occupants and nearby responders before starting PPV. If openings are not managed, the pressurized airflow can drive flames toward people, push heat into safer areas, or push smoke into areas you’re trying to keep tenable. By coordinating with command, keeping interior doors controlled to channel the airflow, and ensuring everyone is aware of the operation, you reduce the risk of unexpected fire spread and improve safety for both occupants and responders.
