Limitation of using a thermal imager for a structural search
What is May not be able to detect fires on a lower floor if structure is carpeted?
The action immediately following ventilating a compartment that is in ventilation-limited decay
What is Water application to cool gases and surfaces?
What is the water delivery device that flows a minimum of 350 gallons of water per minute called?

Once firefighters have verified from the outside that the floor above the basement is there, this is the only reliable way to determine if the floor is structurally sound
What is Visually inspecting the floor joists?
The structural integrity of a building is most affected by the intensity of the fire and
the amount of water used for extinguishment
The priority before any search
What is Locating and isolating the fire?
The goal of tactical ventilation performed as part of overhaul
What is To reduce smoke damage to structure?
Automatic fog nozzles maintain a near constant _______ regardless of the pattern setting
Pressure
The primary mission at most incidents involving small unattached structures such as storage sheds, pump houses, or fishing houses
What is Prevent fire spread to exposures and then extinguish the fire?
Spalled concrete is an indicator of
possible loss of structural integrity
The oriented-search method used in primary search.
What is The team leader remains anchored while others search the room; the crew remains in constant communication
Never direct a ______ stream into a horizontal exhaust opening when interior attack crews are inside the structure because it will force smoke, heat, and steam toward them
What is a Fog stream?

The purpose of a primary search
What is To rapidly determine the location of victims?
When using positive-pressure ventilation to ventilate a multistory building, it is best to
apply positive pressure at the lowest point (ground level)
What is the indicator notch on hose couplings that lines up when the threads are lined up to engage properly?
The Higbee indicator
At the entry point of a structure fire with an upper layer of smoke and hot gases, these actions will help improve interior conditions
What is Applying the water to the ceiling using a straight stream in a side-to-side motion?
