🔍 Key Concepts

• 46 CFR Subchapter M requirements for towing vessel fire protection • Differences between fuel systems for portable equipment and for outboard engines • Conditions under which portable fuel tanks are permitted on inspected towing vessels

💭 Think About

• Think about whether the regulations focus on the type of equipment (bilge/fire pump vs. outboard) or the safety standard of the fuel tank/system itself. • Ask yourself: do the rules allow only one specific use of portable fuel tanks, or do they recognize multiple acceptable uses if safety requirements are met? • Consider whether the phrase "meet published safety standards" changes what is allowed for other uses mentioned in the choices.

✅ Before You Answer

• Check which uses of portable fuel systems are explicitly mentioned as allowed in the towing vessel fire protection regulations. • Verify whether the regulations require portable tanks to comply with recognized safety standards (e.g., UL, ANSI, or similar) regardless of how they’re used. • Confirm if the regulations group these allowances together in a single provision or treat them as separate, unrelated exceptions.
