🔍 Key Concepts

• Differences in how dry chemical and CO₂ extinguishers attack a fire (cooling, smothering, interrupting chemical reaction) • Typical effective range and discharge pattern of portable extinguishers • Trade‑offs between cleanliness and effectiveness in real shipboard fires

💭 Think About

• Think about what CO₂ is especially known for on a vessel: is it mainly cooling, smothering, or something else? • What happens to visibility and residue in a compartment after using a dry chemical extinguisher versus CO₂? • Which type is more likely to reach a fire that is a bit farther away from you?

✅ Before You Answer

• Verify which agent actually provides significant cooling versus primarily displacing oxygen • Compare the effective range of a typical portable dry chemical unit with that of a portable CO₂ unit • Consider whether dry chemical is known for being clean or for leaving residue on equipment and spaces
