Classification of fire extinguishers
　　
Many types of fire extinguishers, as it moves through can be divided into: portable and trolley; as to the source of power driven fire extinguishing agent may be divided into: gas cylinder type, reservoir pressure, chemical reaction, according to the filling of the extinguishing agent, can be divided into: foam, dry powder, halon, carbon dioxide, acid and alkali, clear water, etc.
　　
The use of fire extinguishers and adaptation (hand-held)
　　
1. fire extinguishers to adapt and use methods
　　
Scope of application
Suitable for extinguishing fire General B class, such as oil products, oil and other fire, could also apply to A class of fire, but not fight class b fire water soluble combustible, flammable liquid fires, such as alcohols, esters, ethers, ketones, fire; nor can fight live equipment and C class and class d fires.
Use: the upper cylinder may be portable, quick reference to rushed to the scene. At this point it should be noted that no fire extinguisher excessively inclined, cannot take or upside down, sideways so that the two chemicals blended out ahead of time. When the distance from the burning point 10 meters, you can invert the tube, a hand hold references to the ring and one hand on the bottom circle lived cylinder, Jet at combustion. In case of fire extinguishing combustible liquids, such as combustion is flowing shape, the foam from far and near Jet, make foam covered entirely in combustion liquids; such as combustion within the container, the container of foam inside the bubble along the inner wall of the shed, gradually covering the burning surface. Do not spray liquid directly aligned to avoid impact due to the Jet, but will be burning liquid melted or rushed out of the container, expand the range of combustion. In case of fire extinguishing solid substances, should be the most severe burning Jet alignment. Firefighting as effective spray distance of shortening, users should gradually to the combustion zone near, and always will foam sprayed in burning until the fight. Use the fire extinguishers should always keep upside-down state, otherwise disrupt Jet.
(Hand-held) foam fire extinguishers deposited should choose a dry, cool, ventilated and convenience, not close to high temperature or may be affected by exposure to prevent decomposition of carbonates and failure; in winter to take measures to prevent Frost frozen; and should regularly wipe dust, dredge nozzle so that it remains open.
2. go-cart-type fire extinguishers to adapt and use methods

It fits the fire and portable chemical foam fire extinguishers of same.
Use: use, generally by two operations, the first fire quickly sliding into the fire, at a distance of 10 meters on fire point be stopped by a man cast spray hose, spray and hands at burning; another then the first counterclockwise turning handwheel, will screw up to the highest position the bottle cap on foot, then the cylinder to the lever after dumping ground, and the valve handle is rotated 90 degrees, you can spray foam for fire suppression. Such as valves mounted on a gun, you are responsible for the operation of spray valve open.
Fire-fighting methods and considerations and portable chemical foam fire extinguishers are basically the same, you can reference. As a result of such fire extinguishers spray distance, continuous injection of a long time, and thus can give full play to its advantage to fight large tank or tank car, the beginning of the fire department.

3. air-foam fire extinguishers adapt fire and use methods

Scope of application:
Scope of application is basically the same chemical extinguisher. But resistance to stripping foam fire extinguishers can fight water-soluble flammable, combustible liquid fires such as alcohols, ethers, ketones, such as the beginning of the solvent burning fires.
Use the method:
Use to mobile or shoulder quickly ran to the scene, the combustion of 6 meters, pull out the insurance sold in one hand holding the opening pressure, another hand grip spray gun; exertion pinch open pressure to open the sealed or Pierce gas cylinder gasket, air bubbles from the spray gun mouth spray out. Fire-fighting methods and portable chemical foam fire extinguishers of same. But the use of air-foam fire extinguishers, fire extinguishers should be always keep upright, not to reverse or lying, otherwise disrupt Jet. At the same time should always hold opening pressure, not just let go, otherwise also breaks Jet.

4. the acid-base fire extinguishers fire and use methods of adaptation
　
Scope:
Suitable for extinguishing A class beginning of combustion, such as fire wood, fabric, paper, and so burning fire. It cannot be used to fight B substances burning fire, for fighting c flammable gas or light metal fire D class. It also cannot be used to extinguish the fire of charged objects.
Use:
Should be used to link upper hand drum, quickly ran to the fire place. Never be fire extinguishers carried on his back, nor excessively inclined to prevent two liquid spray mixture in advance. At a distance of 6 meters of combustion can be reversed, and fire extinguishers and shake a few times, so that the two solutions accelerate mixed; a hand hold references to the ring with one hand and grab the shell of bottom circle will emit burning Jet at the fiercest spray. At the same time as reducing spray distance, use people should push the combustion Department.

5. the use of carbon dioxide fire extinguishers

Fire as long as the fire extinguisher referred or carry to the fire, burning in the distance of 5 meters, put the fire out of the insurance sales, hand hold megaphone root handle with one hand and hold the on-off valve for pressure. Do not spray hose of fire extinguishers should be put on a plate megaphone to 70-90 degrees. When used, you cannot directly use hand seize megaphone wall or metal connection pipe to prevent hands were frostbitten. Fire, when the combustible liquid is flowing like Burns, users will composed of carbon dioxide near and far jets to flame Jet. If combustible liquids in containers Burns, users should lift the megaphone. From one side of the upper part of the container to the combustion of the spray in the container. But not the CO2 jet direct attack on the combustible liquid surface to prevent the use of combustible liquids out of the container and the expansion of the fire, the fire caused difficulties.

Trolley carbon dioxide fire extinguishers general operation by two people, two people will push or pull to fire extinguishers, fire department, a burning 10 meters stoppedNext, a person quickly remove the megaphone and expand the Jet hose, hold megaphone root handle, another quick counterclockwise rotation handwheel, and drove up to the maximum position. Fire-fighting methods and portable way.
Carbon dioxide fire extinguishers, outdoor use, you should select the poop Jet. In the outdoor use of within a narrow space, fighting back the operator should leave promptly to prevent suffocation.

7.1211 extinguishers use method

When used, should be a reference to the portable fire extinguishers or shoulder fire extinguisher into the scene. In the distance of 5 meters at the burning down of fire extinguishers, first pull out the insurance sold in one hand hold on the one hand in front of the Jet hose nozzle. Such as fire extinguishers without blast hose, hand holding the opening pressure, another hand live fire extinguishers at the bottom of the base circle. Burning the nozzle alignment, firmly hold the opening pressure, so that the fire extinguisher Jet. When the combustible liquid rendered fighting flowing like Burns, users should access the flame root from near and far and fast forward about fire, until the flame all fight. If combustible liquids in containers of combustion, flame fire, when around shaking flame was driven out of the container, the Jet stream with flame fire until the fire all the fight. But it should be noted that cannot be jet direct injection in combustion liquids to prevent fire extinguishing agent will cushion the impact of combustible liquid out of the container and the expansion of the fire, the fire caused difficulties. If you fight combustible solid substances from the beginning of a fire, a Jet at the fiercest spray combustion, when the flame is extinguished, shall promptly take measures to prevent its recurrence. 1211 fire extinguishers to use couldn't upside down, or lying, otherwise the agent is spraying out. In addition to outdoor use, you should select the poop Jet; in small indoor fire extinguishing, fire after the operator should quickly evacuated, 1211 fire-extinguishing agent also has a certain degree of toxicity, to prevent harm to the human body.

8. the trolley-1211 fire extinguisher use method
Fire suppression is generally consists of two operations, the first fire extinguisher push or pull the fire burning in the distance of 10 meters at stop, one quick release spray hose, hold spray gun, at the burning; another is quickly open fire valves. 1211 fire-extinguishing methods and hand-held fire extinguishers are the same.
Trolley-type fire extinguisher maintenance
Trolley-fire-extinguishing appliances maintenance requirements are the same as with hand-held fire extinguishers. 1211
The use of fire extinguishers 9.1301
1301 fire extinguishers for use, and the same scope and 1211 fire extinguishers. But because 1301 fire extinguishing agent emit into the mist, outdoor wind conditions, the fire-fighting capability no 1211 fire extinguishers should be high, therefore the poop Jet.

10. adaptation of fire extinguishers and the use method

Sodium bicarbonate dry chemical fire extinguisher suitable for flammable and combustible liquids, gases and the beginning of the line equipment; fire extinguishers in addition to the ammonium salt can be used for these types of fire, fighting solid substances in the beginning of a fire. But none can fire extinguishing metal combustion.
Fire-fighting, mobile or shoulder fire quickly rushed to the scene, at the distance of 5 meters at the burning down of fire extinguishers. If outdoors, you should select the poop Jet. Use dry chemical fire extinguisher if plug-in-reservoir pressure, the operator should hand grip spray gun, the other hand lift the gas cylinder opens mentioned on. If the opening of the gas cylinder is hand wheel, the counterclockwise direction swing and swing to the highest position, then lift the fire extinguisher. When the dry powder spray, quick alignment fire flame roots. Use dry chemical fire extinguisher if built-in air tank or reservoir pressure, the operator should be open to the insurance sold disconnect, and then hold the nozzle spray hose front-end, the other will open the pressure put pressure, open the extinguisher. Have a blast hose, fire extinguisher or reservoir pressure type fire extinguishers in use, one should always put the pressure down, can't let go, otherwise disrupt Jet.

Dry powder fire extinguishing combustible, flammable liquid fires, fire flame to Department, if you are fighting for flowed liquid fires are burning, you should access the flame root from near and far, and around the fire until the fire all the fight. If combustible liquids in containers, the consumer should prevail fire flame root to enable around shaking out of dry powder spray flow covers the entire surface of the container openings; when the flame is out of the container, the user should continue to spray until all the flame extinguished. In extinguishing the fire of flammable liquids in containers and should be can't direct alignment liquid jet nozzle, preventing the impact that Jet-combustible liquid spills and the expansion of the fire, causing fire. If when combustible liquid in metal container burning time is too long, the container wall temperature is higher than the Suppression of ignition of flammable liquids, at this point, it is easy to result comes alive again after the fire, if combined with foam types of fire extinguishers, fire extinguishing effect is better.
The use of ammonium phosphate dry powder fire extinguishing solid fuel fire should associate the most violent spray combustion and from top to bottom, left and right. If conditions permit, the user is permitted to carry fire extinguishers along four neighboring combustion nozzle while walking, so that the powder extinguishing agent evenly spray combustion of the surface, until all the flame extinguished.
