🔍 Key Concepts

• Foam fire-fighting principle – foam works by forming a blanket on the surface of the burning liquid to smother vapors • Bilge fire characteristics – fires in bilges often involve fuel or oil on top of water in a confined low space • Gentle application of foam – hard, plunging streams can break up the foam and splash burning liquid

💭 Think About

• Which direction of application will help the foam form a smooth, unbroken blanket over the burning surface rather than breaking it up? • In a bilge fire, where is the burning fuel likely located, and how can you get foam to spread over that surface most effectively? • Which option could cause splashing or mixing of fuel and water, and which helps the foam flow and spread?

✅ Before You Answer

• Identify where the fuel surface is in a bilge fire (on top of the water, not below it). • Consider which option allows foam to flow and spread gently over the burning surface instead of being driven under or through the liquid. • Eliminate any choice that would agitate or plunge into the bilge and disrupt the foam blanket.
