Question 785 Deck Safety
70% to passPortable foam fire-extinguishers are designed for use on class _______________.
A
A and class C fires
B
B and class C fires
C
A and class B fires
D
A, class B, and class C fires
AI Explanation
The correct answer is C) A and class B fires. Portable foam fire extinguishers are designed to be effective on Class A (ordinary combustible) and Class B (flammable liquid and gas) fires, but not on Class C (energized electrical) fires. This is because the foam agent used in these extinguishers is not conductive and could create an electrical hazard if used on energized electrical equipment. The other options are incorrect because they either include the wrong class of fire (A and C instead of A and B) or include Class C fires, which these extinguishers are not suitable for.
