The B determines the type of fire that can be extinguished, and in this case it would be flammable liquids such as gasoline, grease, oil, diesel fuel, and kerosene.
The number indicates the approximate number of square feet the unit can extinguish, so a B-1 would be a relatively small extinguisher.
The b-2 has about twice the capacity of a b-1.
B extinguishers are for putting out flammable liquids. These must be carried on boats.
what does the letter b on a b-1 fire extinguisher mean
The type of fire it is designed to extinguish
Class B fire extinguishers are for fires of flammable liquids (grease, gasoline, oil, propane, paints). The numerical rating of "1" signifies the the number of square feet of the flammable fire that a non-expert could expect to put out.So, a B1 extinguisher will help put a flammable material fire on only one (1) square foot before it runs dry.
B refers to Class B fuel, i.e., flammable/combustible liquid or gas.
You need to use a Class B extinguisher on flammable liquids.
the type of fire it is designed to extinguish <><><> Extinguishers can be class A,B,C,D or K- as said- the type of fire it will extinguish. A type B fire involves burning liquids, such as gasoline, paint, etc.
Burning liquids such as gasoline, kerosene, paint, acetone, and so on.
A type b extinguisher puts out a class B fire, i.e., flammable/combustible liquids and gases.
The B determines the type of fire that can be extinguished, and in this case it would be flammable liquids such as gasoline, grease, oil, diesel fuel, and kerosene. The number indicates the approximate number of square feet the unit can extinguish, so a B-1 would be a relatively small extinguisher.
B on fire extinguishers generally means that it can be used to put out flammable liquid fires. B1 means it will do so, but not especially well (1 is the lowest ranking).A is for flammable solids, C is for electrical fires.Usually the number appears before the letter, so 1-B rather than B1. Properly used, a 1-B extinguisher can be reasonably expected to put out a puddle of flaming liquid about 2.5 square feet in area. If you've never had specific training in using one, you probably WILL NOT use it properly; for flammable liquid fires, unless it's an extremely small fire it's almost always better to call 911 than to try to use a fire extinguisher on it (you're more likely to spread it than extinguish it).
