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

🔍 Key Concepts

• Difference between direct attack and indirect attack in fire behavior • How water streams and extinguishing agents affect flames vs. hot gases/compartment • The purpose of total flooding systems versus cooling or smothering at the fuel surface

💭 Think About

• For each option, ask: Is the method acting directly on the burning fuel/flames, or is it mainly changing conditions (temperature, gases) around the fire? • Which technique relies on using a surface (like overhead or bulkhead) to break up or spread the agent before it reaches the fire area? • Which option is more about protecting exposures rather than attacking the fire itself?

✅ Before You Answer

• Identify which choice involves cooling or disrupting hot gases/atmosphere rather than directly blanketing the burning material • Separate exposure protection (stopping spread) from actually attacking the existing fire • Consider which method is commonly taught as an "indirect" interior attack: using the compartment surfaces to break up a water stream into fine droplets

Question 1 of 27070

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

Spraying foam on a bulkhead and letting it flow down and over a pool of burning oil

Bouncing a straight stream of water off the overhead to create spray effect

Flooding a paint locker with CO2 and sealing the compartment

Cooling adjacent bulkheads with water to prevent the spread of the fire by conduction
