FE Hazard Identification & Risk Assessment 5

Question 1

A hazard assessment of a parking garage identifies vehicle fuel leaks as the primary risk. Which hazard class applies and what agent is recommended?

Accepted Answer

Class B hazard; dry chemical or CO2 extinguisher

Answer

Gasoline and vehicle fluids are Class B flammable liquid hazards, best addressed with dry chemical or CO2 extinguishers.

Question 2

When conducting a hazard assessment in a commercial laundry facility, which factor would most likely elevate the risk from ordinary to extra hazard?

Accepted Answer

Large quantities of lint accumulation near heat sources

Answer

Lint is highly combustible and accumulates rapidly near heat in laundry facilities, significantly increasing fire load and qualifying as extra hazard.

Question 3

A site survey reveals that a previously assessed ordinary hazard area has begun receiving deliveries of cardboard and packing materials stored floor-to-ceiling. How should the technician respond?

Accepted Answer

Reassess the area and upgrade extinguisher coverage to reflect the increased fuel load

Answer

A substantial increase in combustible storage significantly raises the fire load, potentially upgrading the hazard level and requiring additional or higher-rated extinguishers.

Question 4

A risk assessment identifies a chemical plant with both flammable solvents and areas of combustible metal dust. What is the primary challenge in extinguisher selection?

Accepted Answer

No single extinguisher type handles both Class B and Class D hazards; separate units are required for each zone

Answer

Class B and Class D hazards require different extinguishing agents, so separate, zone-specific extinguishers must be placed for each hazard type.

Question 5

A technician notices that an extinguisher protecting a Class B hazard area has been replaced with a unit rated only for Class A. What immediate risk assessment concern does this create?

Accepted Answer

Using a Class A extinguisher on a Class B fire can spread flaming liquid and worsen the fire

Answer

Water-based Class A extinguishers can scatter burning flammable liquids, spreading a Class B fire rather than extinguishing it.
