In accordance with Coast Guard Regulations (46 CFR), what quantity of B-II extinguishers would be required in an oil fired boiler space on a 25,000 gross ton cargo vessel in which no sand, soda impregnated sawdust, or other approved dry materials are provided?
• 46 CFR requirements for fire extinguishers in machinery spaces on cargo vessels • Difference between B-II extinguishers and other sizes/types • How the requirement changes when no sand or other dry materials are provided in an oil‑fired boiler space
• Identify which 46 CFR Part and Section covers portable fire extinguishers in machinery/boiler spaces for cargo vessels over 15,000 gross tons. • Determine the base number of B-II extinguishers required for the oil‑fired boiler space, then check how the rule modifies that number when no sand or dry material is carried. • Ask yourself whether the regulation requires an additional extinguisher (or more) when sand/sawdust is not carried, or if it simply replaces that requirement.
• Verify the exact table or paragraph in 46 CFR that lists the number and type of extinguishers for oil‑fired boiler rooms. • Confirm how the regulation phrases the condition “if no sand or other approved dry materials are provided” — does it say “in addition to” or “in lieu of”? • Make sure you are looking at the line for the correct tonnage range (25,000 GT cargo) and the correct space type (oil‑fired boiler space, not just generic machinery space).
