Best answer: What is used in fire extinguisher formula?

The active material may be a powder such as potassium bicarbonate (KHCO3), liquid water, an evaporating fluorocarbon or the propelling agent itself. The most effective and common fluorocarbon used until recently for this application had been bromochlorodifluoromethane (CF2ClBr), referred to as halon 1211.

What is the chemical formula of fire extinguisher?

the soda acid fire extinguisher made by reacting sodium hydrogen carbonate(nahco3) and sulphuric acid (h2so4) . a little glass container is tied along a bottle cap and the bottle contains nahco3 solution in it .

Which compound is used as fire extinguisher?

Carbon dioxide (CO2) fire extinguishers are used for Class B and C fires. They emit pressurized CO2 gas, which smothers the fire by blocking the oxygen that the fire needs. Unlike the dry chemical types, this nonflammable gas quickly evaporates leaving nothing behind.

Which gas is used in fire?

Carbon Dioxide (CO2) Fire Suppression Systems

Unlike clean agents, carbon dioxide puts out fires by removing oxygen, not heat. This is a critical difference, because it means that carbon dioxide can not be used in occupied spaces. Because carbon dioxide removes oxygen, it can suffocate people.

What are the 4 types of fire extinguishers?

There are four classes of fire extinguishers – A, B, C and D – and each class can put out a different type of fire. Multipurpose extinguishers can be used on different types of fires and will be labeled with more than one class, like A-B, B-C or A-B-C.

Which gas is called dry ice?

“Dry ice” is actually solid, frozen carbon dioxide, which happens to sublimate, or turn to gas, at a chilly -78.5 °C (-109.3°F). The fog you see is actually a mixture of cold carbon dioxide gas and cold, humid air, created as the dry ice “melts” …

What is the difference between ABC and CO2 fire extinguisher?

CO2s are designed for Class B and C (flammable liquid and electrical) fires only. Carbon Dioxide is a non-flammable gas that extinguishes fire by displacing oxygen, or taking away the oxygen element of the fire triangle.
