CAL FIRE Fire Captain Practice Test

The main idea is to protect life safety and establish safe routes before doing the actual smoke removal. Pressurizing the Fire Attack stairwell first creates a clean, protected entry path for firefighters into the fire area and helps keep smoke out of the route they’ll use to reach the fire. Next, pressurizing the Evacuation stairwell safeguards the occupants who are evacuating and keeps that egress path tenable for both civilians and crews. Ventilating the Fire floor is done last to remove smoke and heat once those critical stairwells are secured, improving conditions for suppression without pushing smoke into the stairs. This sequence balances keeping three essential paths—attack, evacuation, and the fire floor itself—in a way that supports safety and effective firefighting on a first alarm.
