Type b fire extinguisher

Answer 1

In restricted visibility, a power-driven vessel under way gives which sound signal every two minutes

*********************************************

A fire extinguisher in class B is used against: FLAMMABLE LIQUIDS such as paraffin, petrol, oil etc.

Answer 2

The letter B refers to Class B fires involving flammable liquids, such as fuel. The US Coast Guard regulations specify a series of extinguishers by their relative ability to extinguish increasing amounts of fire.

A B-I extinguisher (required on just about any powerboat) would correspond to the extinguishing characteristics of a UL listing 5-B:C, rated for 5 sq ft of liquid fire, with 2 pounds of dry chemical. However, B-I could also be a CO2 extinguisher with 4 pounds or a foam extinguisher with 6 quarts of capacity.

In addition to a B-I capacity, a marine extinguisher would also be required to have a USCG certification before it could be marketed or installed as USCG B-I.

A UL 1-B fire extinguisher, on the other hand, means it has a UL rating of 1-B. The unit will extinguish a 1 sq. ft. flammable liquid fire by a novice user.

For reference, a B-II has 5 pounds of dry chemical, or 15 pounds of CO2 or 10 quarts of foam.

Answer 3

Like any other Class B fire extinguisher, a B-1 or B-I extinguisher puts out fires involving flammable liquids. To have a B-1 rating it would need the ability to extinguish at least 5 square feet of flaming liquid (i.e., 2 pounds of dry chemical or 4 pounds of CO2 or 6 quarts of foam). It would also have to conform to US Coast Guard regulations for packaging, labeling and so forth to get a USCG rating.
