88. How many B-II hand portable fire extinguishers are required in the machinery space of a 260 GT uninspected tow vessel with 2400 B.H.P.?
46 CFR Part 25.30 requires three B-II hand portable fire extinguishers in the machinery space; this is determined by dividing the total brake horsepower (2,400 B.H.P.) by 1,000 and rounding up, as any fraction of 1,000 B.H.P. necessitates an additional extinguisher, and gross tonnage is irrelevant to this calculation.
