Which pattern made up of small particles of agent is excellent for absorbing heat and creating a cooling foam blanket?

• A. Solid pattern
• B. Dispersed pattern
• C. Stream pattern
• D. Wide pattern

Answer: (B)

The dispersed pattern is excellent for absorbing heat and creating a cooling foam blanket because it involves the distribution of small particles of firefighting agent throughout a larger area. This pattern maximizes the agent's surface area, allowing for more effective absorption of heat from the fire. The small particles enhance the foaming action by entrapping air, which contributes to the formation of a foam blanket that can smother the fire while also cooling the surrounding area. This cooling effect is crucial in firefighting, particularly in aviation rescue and firefighting operations, where intense heat loads are present. By using a dispersed pattern, the agent can provide enhanced coverage and a more efficient barrier against flames, making it a preferred choice in these situations.
