🔍 Key Concepts

• Small passenger vessel regulations in 46 CFR Subchapter T (vessels <100 gross tons carrying passengers for hire) • Differences between volatile liquid fuels and solid fuels used for cooking • Fire and explosion risk of fuels in enclosed spaces on passenger vessels

💭 Think About

• Think about which of these fuels produces the most dangerous vapors in an enclosed galley space if spilled or leaking. • Ask yourself which fuel is most strictly controlled or prohibited on passenger vessels because of explosion hazard rather than just fire hazard. • Consider which fuels tend to sink and pool in low areas as vapors, creating a serious risk in bilges and machinery spaces.

✅ Before You Answer

• Verify which fuel has very low flash point and forms explosive mixtures with air easily. • Check which fuel’s use for cooking is specifically restricted or prohibited in small passenger vessel rules (46 CFR Subchapter T). • Confirm which of these options would be most critical to keep completely out of the galley on a passenger-for-hire vessel due to vapor explosion risk, not just flame or smoke.
