Q

When conducting PPA operations: if there is fire attack going on, and a search team goes interior, what should the search team do if they encounter a closed door ?

A

Leave the door shut and only search OPEN compartments. Opening new doors have high potential to change the flow path. Crews need to enter and exit the structure from the intake only.
