Question 1 of 27070

Which of the following fire extinguishing agents is best suited for use on a large class "B" fire occurring on the open deck of a vessel?

🔍 Key Concepts

• Class B fires involve flammable liquids like fuel oil, gasoline, and solvents • On an open deck, wind and ventilation affect how agents disperse • Some agents are better for large surface-area fuel fires than others

💭 Think About

• Which agent can both smother the fire and help prevent re‑ignition of flammable liquids spread over a large area? • How effective is each option when used outdoors, where gas or powder can blow away? • Think about which agents are commonly used for deck fuel fires and helicopter deck fires on ships.

✅ Before You Answer

• Verify which agent is specifically designed to form a blanket or film over liquid fuel on the surface • Consider which agents might quickly disperse in the wind on an open deck and lose effectiveness • Eliminate any option that is mainly designed for use in enclosed spaces or machinery spaces, not open deck areas
