B-I and B-II refer to the relative fire extinguishing capacity of approved USCG fire extinguishers, depending upon the type of extinguishing agent used.
Class B fires involve flammable or combustible liquids such as gasoline, kerosene, grease and oil.
The numerical rating BEFORE the letter B, for class B extinguishers, indicates the approximate number of square feet of fire it can extinguish (i.e., with no significant depth).
The numerical rating (I, II, III) AFTER the letter B indicates Coast Guard classification. For example, a UL 5-B:C, rated for 5 sq ft of liquid fire, would be a USCG B-I extinguisher (with 2 pounds of dry chemical).
To obtain a USCG B-II rating you would need the equivalent of 10 pounds of dry chemical, such as having two UL 3-A, 40-B:C extinguishers, or a 15-pound CO2 extinguisher, or 2 1/2 gallons of AFFF "foam" (UL 3-A:20B).
A 20-pound dry-chemical (120-B:C) would meet USCG B-III requirements.
USCG ratings go as high as V, which is a big extinguisher on wheels.

Which one of the following is a coast guard requirement for a fire extinguisher?
A Coast Guard requirement for a fire extinguisher is that it must be USCG-approved and appropriately sized based on the vessel's length and type. Additionally, it must be readily accessible, properly mounted, and maintained in good working condition. Vessels over 26 feet are typically required to have at least one B-1 type fire extinguisher. Regular inspections and servicing of the extinguisher are also necessary to ensure compliance.
A fire extinguisher is labeled B-I. What type of fire will be put out by this extinguisher?
Burning liquids such as gasoline, kerosene, paint, acetone, and so on.
What does a B-1 fire extinguisher do?
B-I is the minimum US Coast Guard approval rating for extinguishers on powerboats. It corresponds to a UL Class 5-B:C, 2-pound, dry chemical extinguisher that has been properly packaged and mounted for USCG approvals as well. It could also mean a 4-pound CO2 extinguisher or a 7-quart foam extinguisher. What can you do with it? Well, a B-1 rated extinguisher is just the thing for putting out "flammable liquid" fires on boats, a B-1 or B-2 rated extinguisher being required by the Coast Guard to operate the vessel. If the gasoline or diesel fuel spills and catches fire, your extinguisher will probably be adequate to put it out, provided that you act promptly. The UL 5-B rating implies that a novice firefighter can extinguish 5 square feet of flaming liquid fuel using that extinguisher. The C rating means it is also approved for use on energized electrical fires, i.e., it is non-conductive.
