70% to pass

Which firefighting method is an example of an indirect attack on a fire?

A Cooling adjacent bulkheads with water to prevent the spread of the fire by conduction
B Spraying foam on a bulkhead and letting it flow down and over a pool of burning oil
C Bouncing a straight stream of water off the overhead to create spray effect
D Flooding a paint locker with CO2 and sealing the compartment
AI Explanation

The correct answer is D) Flooding a paint locker with CO2 and sealing the compartment. This is an example of an indirect attack on a fire because it deprives the fire of oxygen by flooding the compartment with a suffocating agent, rather than directly applying water or foam to the fire itself. Flooding a compartment with CO2 is an effective way to extinguish a fire without directly contacting the flames, making it an indirect firefighting method. The other answer choices describe direct attack methods, such as cooling adjacent surfaces, applying foam, or using a water spray pattern. These approaches involve directly applying an extinguishing agent to the fire or its immediate surroundings, rather than depriving the fire of oxygen by sealing off the compartment.
