FireTEAM Problem Sensitivity Flashcards

A firefighter notices that the smoke coming from a structure is changing from gray to black and thickening rapidly. What does this most likely indicate?

Answer: The fire is intensifying and consuming more fuel

Darkening, thickening smoke indicates increased fire intensity and heavier fuel consumption, signaling a more dangerous situation.

While performing a primary search, a firefighter finds a door that is warm to the touch but not hot. What should the firefighter do before opening it?

Answer: Open it slowly while staying low and to the side

A warm door may indicate fire or superheated gases on the other side; opening slowly while staying low and to the side protects the firefighter from a potential flashover or backdraft.

A hoseline team is advancing when they notice water pressure suddenly drops significantly. What is the most likely problem?

Answer: There is a kink in the hose or a supply issue

A sudden drop in hoseline pressure typically indicates a kink, coupling failure, or a problem with the water supply.

A firefighter on the roof notices the roof surface feels spongy underfoot near the fire area. What should the firefighter do?

Answer: Immediately move away and notify command of roof integrity concerns

A spongy roof indicates structural weakening from fire below; the firefighter must exit immediately and report the hazard to prevent collapse.

During overhaul, a firefighter smells natural gas in the structure. What is the highest priority action?

Answer: Evacuate all personnel and notify command immediately

Natural gas creates an explosion hazard; all personnel must evacuate and command must be notified so utilities can be shut off safely.

A firefighter observes that flames are visible from multiple floors of a building simultaneously upon arrival. What problem does this most likely indicate?

Answer: The fire has extended vertically through the building rapidly

Multi-floor flame involvement typically indicates rapid vertical fire spread through utility shafts, stairwells, or wall voids.

While donning SCBA, a firefighter notices the low-pressure alarm activates immediately when the air cylinder valve is opened. What does this indicate?

Answer: The cylinder is nearly empty or not fully charged

An immediate low-pressure alarm indicates the cylinder pressure is below the minimum safe threshold and the SCBA should not be used.
