class b fires use the following as fuel
Metals magnesium and sodium. That normally do not leave any embers or residues or very low amounts of residues.

Extinguishers with an A rating are designed to extinguish fires involving these ordinary combustible materials.
. Class B fires- Involve flammable or combustible liquids such as gasoline oil grease and paint. Class B fires involve flammable and combustible liquids such as gasoline alcohol oil-based paints lacquers. Gasoline oil grease acetone.
QUESTION 2 The fire tetrahedron consists of the following elements. Class B fire refers to a fire involving flammable liquids such as petroleum gasoline kerosene petrol diesel octane etc paint alcohol solvent oil and tar etc. There are four classes of fires.
Creating a chain reaction between the molecules of the burning material. They contain an extinguishing agent and use a compressed non-flammable gas as a propellant. Class B fires involve flammable and combustible liquids such as fuels paints solvents and grease.
O Use a Class B or Class ABC fire extinguisher. Flammable liquids such as alcohol ether oil gasoline and grease which are best extinguished by smothering. Chemicals such as magnesium aluminum or potassium.
Water is a particularly dangerous extinguishing medium for class C fires because of the risk of electrical shock. Lowering the temperature of the. Class C fires are electrical fires.
Combustible metals When operating a fire extinguisher remember the mnemonic PASSPASS represents the steps used to properly. It has a moderate spray range and last only 10 to 30 seconds. Class A fires involve ordinary combustible materials such as cloth wood paper rubber and many plastics.
Ordinary solid combustibles such as paper wood cloth and some plastics. Flammable liquids include petroleum-based oils or paint tars alcohol oils solvents gasoline and kerosene. Dry chemical extinguishers are usually rated for class B and C fires and may be marked multiple purpose for use in A B and C fires.
Class B Fires Extinguish by Depleting Oxygen. CLASS B Fires These fires are burning flammable liquids such as gasoline greases hydraulic oil diesel fuel and lubricating oils. Flammable liquids gases and solvents.
Such as petrol turpentine or paint Class C fires flammable gases. O Do not use a Class A extinguisher on this type of fire. Most of these liquids have a high carbon content and the compounds in them and are highly combustible.
Use a Class C or Class ABC fire extinguisher on these types of fires. Class B fires flammable liquids. The fuel sources of class B fires gases and liquids can be quite volatile and cannot be extinguished by water which will only make the fuel source spread thus spreading the fire.
It may spread the flames. Be thorough when using a CO 2 extinguisher. When used for Class B and C fires the CO 2 covers the fuel by blanketing it and stops the reaction at the surface by displacing oxygen.
Solid combustible materials that are not metals. Class C fires- Involve energized electrical equipment such as office equipment outlets motors power tools and heaters. ABC fire extinguishers are red in color and range in size from five pounds to 20 pounds.
It is therefore very important to understand the four different classifications of fuel. A Class B fire is best extinguished by. Lowering the temperature of the burning wood or paper.
Class A - Wood paper cloth trash plastics. A fire in a coal bunker b fire in a fuel tank c fire in a lumber pile d fire in an electrical panel e fire in a pile of paper 010100020021000D The major advantage of carbon dioxide as a fire extinguishing agent for fires in electronic equipment is it a has superior cooling ability over other agents b is non-toxic c does not reduce the oxygen content of the area d does not leave a. A class-D fire extinguisher can be used to treat fires involving _____as fuel source.
Wood paper cloth rubber trash and plastics. Class B fires are known to result from an explosion of flammable liquids or gases. Any non-metal in a liquid state on fire.
Operate the extinguisher and it stands for which of the following. Smothering the burning liquid. Flammable gases include butane and.
The fire occurs in the fumes over the surface of flammable and combustible liquids. This preview shows page 1 - 2 out of 3 pages. Like hydrogen butane or methane Class D fires combustible metals.
Class B - Flammable liquids. That is why it is important only to use extinguishing agents and methods designed specifically for Class B fires. QUESTION 1 Class B fires involve which of the following fuels.
