🔍 Key Concepts

• Carriage of hazardous materials on tank vessels • USCG regulations on fire hazards in crew stores and on the bridge • Difference between ordinary household matches and “strike-anywhere”/phosphorous” matches

💭 Think About

• Which type of matches is specifically mentioned as being allowed or prohibited for vessels carrying flammable cargo? • Think about which match type is least likely to ignite accidentally if dropped, stepped on, or rubbed against a rough surface. • Which option sounds like a regulatory term you would see in a safety rule, versus more of a marketing or casual description?

✅ Before You Answer

• Check 46 CFR parts dealing with flammable/combustible materials and fire hazards on tank vessels. • Verify which type of matches is explicitly prohibited due to being easily ignited by friction (for example, on any rough surface). • Confirm which match description aligns with common household matchbooks intended to reduce accidental ignition rather than special-purpose or high‑risk matches.
