Question 1 of 27070

According to U.S. Coast Guard Regulations (46 CFR), portable Halon fire extinguishers used on a MODU may be charged with __________.

🔍 Key Concepts

• 46 CFR requirements for portable fire extinguishers on MODUs (Mobile Offshore Drilling Units) • Differences in approved Halon agents (1301, 1211, 22) and their typical applications on vessels • Which Halon types are commonly used in portable units versus fixed flooding systems

💭 Think About

• First, think about which Halon agent is most often used for fixed fire-extinguishing systems in machinery spaces, and which is used more commonly in portable extinguishers. • Ask yourself: does 46 CFR usually limit you to just one Halon type for portables, or does it allow more than one specified type? • Consider whether Halon 22 is commonly listed in current USCG approval language for MODU fire protection, compared with 1301 and 1211.

✅ Before You Answer

• Check 46 CFR Part 108 (especially Subpart D – Fire Protection for MODUs) for the exact wording on portable Halon extinguishers. • Verify which Halon types the regulation explicitly pairs together when mentioning portable extinguishers (not fixed systems). • Confirm that the agent(s) you choose are actually listed as acceptable for portable use on MODUs, not just mentioned elsewhere for other fire systems.
