What is the chemical inside fire sprinklers?

Answer 1

Nothing other than water!!!!!!!!!11

Answer 2

I think I know what you mean. In fire sprinklers there is water of course to put out the fire. However what they do is put a piece of cadmium or a gallium alloy inbetween the water port and the head. When a fire gets hot enough this piece of metal will melt and release the water. In some other systems such as in computer rooms there is usually carbon dioxide or halon. This is to ensure that that the fire is deprived of oxygen that fuels the fire. Also it will not leave a powdery residue on the computer components

Answer 3

Depends on the system!

Fire sprinkler systems in most buildings use water to inundate and douse the fire. However, some systems in military vehicles use Freons to extinguish engine fires.

Fire extinguishers come in several different types, labeled A, B, and C, depending on the type of fire you're trying to extinguish.

A Type A fire extinguisher is used for small fires in ordinary combustibles such as paper and wood -- most of them use water.

Type B fire extinguishers are used for fires involving flammable liquids -- they include carbon dioxide and foams. Water is a no-no here, because spraying water on a flammable liquid generally will spread the flames, rather than extinguishing them.

Type C fire extinguishers are intended for electrical fires -- they often involve dry powder exitnguishers or carbon dioxide.

Answer 4

Generally it is water. Sometimes it is air with the water following after the fusable link melts. (To avoid freezing in un heated areas)
Rarely, there is a surfactant added to permit the water to better wet class 'A' combustables. Some very specialized systems permit the addition of foam forming materials to fight petrochemical fires.
