Question

______ is primarily used on class bravo fires?
● co2
● afff
● water
● pkp

Explanation:

Class Bravo fires involve flammable liquids (like oil, gasoline). AFFF (Aqueous Film - Forming Foam) is designed to extinguish such fires by forming a film on the liquid surface to prevent re - ignition. CO₂ is more for electrical/Class C and some small flammable liquid fires but not primary for Class Bravo. Water spreads flammable liquids, worsening Class Bravo fires. PKP (Potassium Bicarbonate - dry chemical) is better for Class A, B, C but AFFF is primary for Class Bravo.

Answer:

B. AFFF
