Fire is unpredictable elements that can cause damage on a catastrophic scale. That is why it is so important to eliminate starting a fire using fire-fighting equipment. Modern industry involves the production of a wide variety of fire extinguishers, which differ not only in weight and form, but in purpose: for different types of fires and different areas of the fire.

Water fire extinguishers

To fire extinguishers of this type include the means of fire safety, designed to neutralize the fire using jets of water under high pressure. Water can be supplied in the form of a strong directed jets, and in the form of dispersed droplets.

Extinguishers of this type are designed to extinguish paper, cardboard, fabric, wood, plastic or trash. For extinguishing solid substances are used water fire extinguishers with a directed stream of water. Combustion of liquid substances is eliminated only melkorazmernaja jet to prevent splashing and to only those fire extinguishers, upon which the mark is added to the water supplementation.

If the fire extinguisher contains only water in its purest form, the major limitations for such fire-fighting equipment will be restrictions on extinguishing flammable liquids and electrical wiring.

Foam fire extinguishers

A means of neutralizing the fire in such fire extinguishers, foam is formed either by gas or by a chemical reaction. Foam blocks access to oxygen, thereby eliminating the fire. Fire extinguishers of the foam type are used to extinguish fire as solid substances and flammable liquids: oil, fuel, etc. in the squares no more than 1 sq m. usage restrictions to apply to the extinguishing of electrical wiring and metals, which by chemical reaction with water, emit oxygen, potassium, sodium.

Powder extinguishers

The basis for extinguishing a fire of such dry powder fire extinguisher are mineral salts with various additives. The powder fire extinguisher is versatile and can be used in case of fire of solid substances, and combustible liquids, and electrical lines energized, and gases under high pressure. The only limitation to the use of powder – burning alkaline earth metals, burning without oxygen. The disadvantage of powder fire extinguishers is the need to work in protective masks because the air is very dusty, and very dirty room, covered with a layer of powder used.

Carbon dioxide gas fire extinguishers

Carbon dioxide extinguishes fire effectively on surfaces of any type and can be used to extinguish fires of solid, liquid, gaseous substances and electrical wiring. The fire extinguisher leaves no residue, but is limited in use due to the inefficiency of large areas. In addition, the accumulation of a large amount of carbon dioxide in the room of fire can lead to poisoning, so it is very important after the fire, immediately move to fresh air.
