🔍 Key Concepts

• 46 CFR requirements for compressed flammable gases in bulk (especially special requirements for butadiene) • Materials compatibility of valves and fittings with specific cargoes (metals that may cause hazardous reactions or polymerization) • Difference between general documentation rules and special cargo-specific rules for dangerous gases

💭 Think About

• Which of these choices looks like a cargo-specific safety restriction that would appear word‑for‑word in a regulation for butadiene, rather than a general practice? • Think about why some metals might be prohibited in contact with certain gases. Which metals are known to promote polymerization or dangerous reactions with butadiene? • For the options about sampling, documentation, and ullage padding: do current rules usually require exact quantities, sampling only at one time, or the use of compressed air on a flammable gas cargo?

✅ Before You Answer

• Look in 46 CFR Part 151 (or the section on special requirements for specific cargoes) for the entry on Butadiene and read the exact conditions listed. • Verify whether any rule allows padding the tank with compressed air for a highly flammable gas like butadiene, or if an inert gas is normally required instead. • Check if the regulation mentions prohibited metals (such as silver, copper, or high‑copper alloys) in parts of valves and fittings that are in contact with butadiene. This is a key safety clue.
