🔍 Key Concepts

• Behavior of different extinguishing agents on chemical fires • Purpose of water in exposure protection and cooling during cargo/chemical incidents • Risks of spreading or reacting when applying water directly to chemicals

💭 Think About

• Think about what can happen if you put a strong solid water stream directly onto a pool of burning chemical cargo. • Consider whether water is usually used to directly extinguish a reactive chemical, or to control the surrounding conditions so the situation doesn’t worsen. • Ask yourself which option best reflects a cautious, containment-focused approach rather than an aggressive attack on the burning chemical itself.

✅ Before You Answer

• Verify which methods might spread the burning liquid rather than control it. • Check which option focuses on heat removal and protection of adjacent structures/tanks instead of direct knockdown. • Eliminate any options that describe tactics likely to agitate, disperse, or react with the chemical.
