Chapter 6 Test: Portable Fire Extinguishers
This is a chapter assessment covering the identification, selection, operation, and limitations of portable fire extinguishers for incipient-stage fires. The test evaluates knowledge of fire classes (A, B, C, D, K) and the matching of extinguishing agents to each fuel type . It heavily emphasizes the PASS operating technique—Pull, Aim, Squeeze, Sweep—including the requirement to aim at the base of the fire and approach with the wind at the operator's back . Assessment items also cover extinguisher rating systems, the distinction between dry chemical and dry powder agents, the mechanism of saponification for Class K fires, and safety protocols such as maintaining an exit route and withdrawing to reassess if the fire is not suppressed after using one full extinguisher .
