Which is an advantage of an ABC dry chemical over a carbon dioxide extinguisher?

🔍 Key Concepts

• Class ABC dry chemical vs. CO₂ (carbon dioxide) extinguishers and what each is designed to fight • How each agent actually puts out the fire (smothering, cooling, interrupting chemical chain reaction) • Meaning of multipurpose in fire extinguishers (classes A, B, C)

💭 Think About

• Look at which fire classes each type of extinguisher is normally rated for and ask: which one can safely be used on the most different types of fires? • Think about the side effects of each agent: residue left behind, effect on visibility, and impact on electrical equipment—then match these to the choices. • Ask yourself which answer choice describes something that is characteristic of dry chemical, not CO₂, when fighting common shipboard fires.

✅ Before You Answer

• Verify which extinguisher is commonly labeled ABC and why that matters. • Check which agent (dry chemical or CO₂) leaves a residue and which leaves no residue. • Confirm which agent is known for no cooling and no reflash protection, and then see which choice no longer fits.
