🔍 Key Concepts

• Firefighting basics on deck – wind direction, approach path, and personal safety • How dry chemical extinguishers work – they interrupt the chemical reaction at the fuel’s surface • Standard extinguisher operating technique – PASS (Pull, Aim, Squeeze, Sweep)

💭 Think About

• Think about which action actually stops the fire from burning, rather than just cooling or blowing it around. • Consider what happens if you aim at the flames instead of where the fuel is. • Ask yourself which options describe good technique, and whether the question is asking for a single best method or a combination. • On an open deck with wind, which position keeps you safest and keeps the extinguishing agent on the fire longest?

✅ Before You Answer

• Verify which part of the fire you should target with a dry chemical agent. • Check standard training for portable extinguishers: Where should you aim and how should you move the nozzle? • Note the wording: "most effective" and whether one step alone is truly sufficient or if they normally work together as a method.
