🔍 Key Concepts

• 46 CFR requirements for portable fire extinguishers on small passenger vessels (under 100 gross tons) • The specific rule for extinguishers at each exit of a propulsion machinery space • Matching extinguisher type and capacity to machinery-space (Class B) fire hazards

💭 Think About

• Decide which fire class (A, B, or C) is the primary concern just outside a propulsion machinery space and which extinguishing agents are best suited for it. • Compare the typical required size/capacity (in pounds or gallons) for machinery-space protection with the sizes listed in the choices. • Ask yourself whether small ‘token’ extinguishers are normally allowed for machinery spaces on passenger vessels, or whether the Coast Guard usually requires something more substantial or a specific minimum rating.

✅ Before You Answer

• Check 46 CFR for the minimum size/rating of portable extinguishers required at exits from machinery spaces on small passenger vessels. • Verify whether the regulations call for a specific type (e.g., foam, CO₂, or dry chemical) at machinery-space exits, or only a minimum rating that corresponds to one or more of the options. • Confirm if any of the listed sizes (2 lb, 15 lb, 2-1/2 gal) actually match a standard Coast Guard-required extinguisher rating for that location; if none do, consider whether “None of the above” might be appropriate.
