Question 1 of 27070

Q

According to U.S. Coast Guard Regulations (46 CFR), a 10 pound dry chemical extinguisher is equivalent to a __________.

🔍 Key Concepts

• 46 CFR fire protection tables that show equivalencies between different types of extinguishers • How dry chemical, foam, and CO₂ extinguishers are rated in terms of "size" or capacity, not just weight • The idea that some extinguishers are much more/less efficient per pound than others

💭 Think About

• Which of these choices seems unrealistically large or small compared with a 10 lb portable extinguisher typically carried on small vessels? • How does the extinguishing capability of CO₂ compare to dry chemical for the same physical size extinguisher? • If you imagine common USCG-required extinguishers on small passenger or inspected vessels, which pairing (dry chem vs CO₂ or foam) feels like a comparable unit, not something used for a completely different scale of fire?

✅ Before You Answer

• Look up the specific 46 CFR subchapter for fire protection (hint: parts in the 25–200 range deal with different vessel types; each has fire-extinguisher tables). • Verify which choice matches the standard USCG-rated portable extinguisher size for a typical machinery-space or galley fire, not a huge fixed system. • Confirm that the extinguisher types you compare are portable units with similar overall physical size, not large wheeled or semi-fixed systems.
