Somebody explain to me why PPV...other than it's a way to ventilate the building.
PPV works for specific situations. If you are conducting VES (contradictory in its own right), you shouldn't be using PPV; unknown location of the victim(s), you shouldn't be using PPV.
The problem with PPV is that once a window or door is opened (controlled or uncontrolled) that opening becomes the or an exhaust point. That window just may be the victims room. Not a good thing if you place life before property.
Don't get wrong...PPV has its applications.
Lt. Rob Fisher - L72
Brake the crew up. The officer and one go inside to search. The senior man goes to vent. When the second or third engine arrives, they send 1 to assist with the venting fire fighter from the truck.
