F02 Hazard Recognition

Question 1

Which of the following is considered a Class B fire?

Accepted Answer

Flammable liquid fire

Answer

Class B fires involve flammable liquids and gases such as gasoline, oil, grease, and solvents. They require smothering or chemical extinguishing agents.

Question 2

What is the primary fire hazard associated with improper storage of combustible materials?

Accepted Answer

Increased fuel load that can intensify a fire

Answer

Improperly stored combustible materials increase the fuel load in a building, meaning fires can grow larger and faster, and may overwhelm sprinkler systems.

Question 3

During a fire watch patrol, which condition would be considered the MOST serious hazard?

Accepted Answer

A propped-open fire door in a stairwell

Answer

A propped-open fire door compromises the building's passive fire protection by allowing fire and smoke to spread freely between compartments, creating an immediate life-safety hazard.

Question 4

What type of fire extinguisher should NEVER be used on a Class C (electrical) fire?

Accepted Answer

Water extinguisher

Answer

Water extinguishers should never be used on electrical fires because water conducts electricity, creating a severe shock hazard for the person using the extinguisher.

Question 5

What is a common cause of fires in commercial buildings that an F-02 Fire Guard should watch for?

Accepted Answer

Overloaded electrical outlets and daisy-chained power strips

Answer

Overloaded electrical circuits and daisy-chained power strips are a leading cause of electrical fires in commercial buildings due to excessive heat buildup in wiring.
