a) High CFM
b) Ladder
c) Smoke
d) Blower

Answer 1

Positive pressure attack (PPA) is a tactical maneuver used in firefighting that uses a ventilation fan to improve smoke conditions and firefighter safety.

Step-by-step explanation:

Positive pressure attack (PPA) is a specific tactical maneuver used in firefighting. It involves using a ventilation fan to achieve a controlled fire and exhaust flow path, improving smoke conditions and firefighter safety. This technique creates a positive pressure inside a structure, forcing smoke and heat out through openings.

By using a high CFM (cubic feet per minute) blower fan, firefighters can push air into the building, pressurizing it and forcing smoke and heat out of windows, doors, and other openings. This helps create a clear and safe path for firefighters to enter and extinguish the fire.
