🔍 Key Concepts

• Review 46 CFR requirements for cargo piping passing through machinery spaces on tank vessels • Understand how cargo grade classifications (A, B, C, D, E, LFG) differ in terms of flashpoint and vapor hazards • Think about why the Coast Guard would allow only less hazardous cargoes in special arrangements through machinery spaces

💭 Think About

• Which cargo grades have the lowest fire and explosion risk based on flashpoint and vapor characteristics? • Why would machinery spaces, with hot surfaces and ignition sources, require stricter limits on the type of cargo allowed in piping? • Among the choices, which represents cargo with relatively higher flashpoints and lower vapor hazard suitable for special-case exemptions?

✅ Before You Answer

• Verify in 46 CFR which cargo grades are explicitly permitted for piping routed through machinery spaces in special cases • Confirm the flashpoint range and hazard classification for each listed grade (A, B, D, E, and LFG) • Ensure that the selected option matches the least hazardous grade(s) that would logically be allowed near ignition sources
