What does the letter 'A' on an extinguisher rating label indicate?
Answer: It is rated for ordinary combustible fires
The Class A rating means the extinguisher is effective on ordinary combustibles like wood, paper, and cloth.
Which extinguisher is recommended for a server room fire?
Answer: CO2 or clean agent
CO2 or clean agent extinguishers are preferred in server rooms because they suppress fire without leaving damaging residue on equipment.
If a fire extinguisher's tamper seal is broken, a Fire Guard should:
Answer: Immediately report it and remove the unit from service
A broken tamper seal suggests the extinguisher may have been partially discharged or tampered with, so it must be removed from service and inspected.
What is the minimum number of portable extinguishers required in a building area according to NFPA 10 travel distance rules for Class A hazards?
Answer: Units must be within 75 feet travel distance of any point
NFPA 10 requires that no point in a light- or ordinary-hazard area be more than 75 feet travel distance from a Class A extinguisher.
A water-type fire extinguisher must NEVER be used on which type of fire?
Answer: Electrical panel fire
Water conducts electricity, so using a water extinguisher on an energized electrical panel creates a serious electrocution hazard.
How should a Fire Guard verify a fire extinguisher is ready for use during a monthly inspection?
Answer: Check that the gauge is in the green zone, seal is intact, and unit is unobstructed
Monthly visual inspections confirm the pressure gauge reads green, the tamper seal and pin are intact, and the extinguisher is accessible and unobstructed.
