A(n) _____ hazard area contains more Class A and Class B materials than ordinary hazard locations, and the combustibility and heat release rate of the materials is high.
Correct Answer:
extra
Explanation:
In fire extinguisher practice, hazard areas are categorized by how dangerous the contents are and how much fuel is present. An extra hazard area has a greater amount and a higher level of hazard from materials than an ordinary hazard area, with materials that are highly combustible and release heat rapidly. That combination—more Class A and B materials and a high rate of heat release—fits the description of an extra hazard location, making it the best choice. The other terms aren’t standard classifications for this level of hazard, so they don’t align as well.
