Final answer:
A Class A fire extinguisher with a 6-A rating is capable of extinguishing a fire comparable to 7.5 cubic feet of ignited pinewood. It's essentially equivalent to using 7.5 gallons of water.
Explanation:
In the context of fire safety, if a Class A fire extinguisher has a rating of 6-A, it means it should be able to extinguish a fire equivalent to an initial load of 7.5 cubic feet of ignited pinewood. The number before the letter 'A' in the rating signifies the equivalence in gallons of water, with 1 representing 1.25 gallons of water. So, a '6-A' rating would be equivalent to 7.5 gallons of water used to quench a wood crib fire.
