Positive Pressure Attack (PPA)

What Is Positive Pressure Attack (PPA)?

Positive Pressure Attack (PPA) is a fire suppression tactic involving the use of a fan or blower to introduce air at a higher pressure into a structure, typically through a controlled entry point, to push smoke and heat away from firefighters and occupants. This method improves visibility and reduces thermal stress while the attack line applies water to control the fire. Not to be confused with positive pressure ventilation, PPA integrates suppression and ventilation efforts under coordinated fireground tactics to enhance safety and efficiency.

Why Positive Pressure Attack (PPA) Matters on the Fireground

PPA can improve firefighter safety by managing the flow path and reducing hazardous conditions such as heat and smoke accumulation. It supports faster fire control and occupant rescue by improving interior conditions and maintaining situational awareness during interior attack operations.
