5. The right hand grasps the cylinder ear, the left hand grasps the bottom edge of the cylinder, the nozzle toward the burning area, standing away from the source of the fire eight meters away from the place of the jet, and keep moving forward, the pocket around the flames of the jet, until the fire is extinguished. 6. After extinguishing the fire, the fire extinguisher lying on the ground, the nozzle facing down.
Third: the use of carbon dioxide fire extinguishers are mainly applicable to a variety of flammable, combustible liquids, combustible gas fires, but also to fight the incipient fires of instruments, books and archives, crafts and low-voltage electrical equipment. 1. hold the pressure handle with your right hand 2. carry the fire extinguisher to the scene with your right hand 3. remove the seal 4. pull out the safety pin 5. stand two meters away from the source of the fire, the left hand holding the flapper, the right hand pressed down hard on the pressure handle 6. the root of the fire source spray, and keep pushing forward until the flame is extinguished Fourth: the use of trolley-type dry powder extinguishers Mainly used to extinguish the flammable liquids, flammable gases, and electrical equipment of the incipient fire.
This fire extinguisher is easy to move, simple to operate, and has a good extinguishing effect. 1. pull or push the dry powder car to the scene 2. right hand grasps the powder spray gun, the left hand unfolds the powder spray hose until straight, can not be bent or circled 3. remove the seal, pull out the safety pin 4. press the gas supply valve with the palm of your hand vigorously 5. left hand holds the powder spray gun pipe holder, right hand holds the gun handle, snap the powder spray switch with your fingers and spray against the flame, and constantly lean forward to swing the gun left and right to cover the dry powder in the combustion zone until the fire is extinguished. Fire extinguished.
Attachment: home commonly used fire extinguishing methods Once a fire at home, first of all, can not panic, and secondly, to take a scientific method to extinguish the fire. Now introduces several commonly used fire extinguishing methods: 1, water cooling method will be directly sprayed to the burning water, extinguish the flame, or water sprayed to the nearby unburned combustibles, so that combustibles from the threat of heat radiation from the flame, to avoid combustion.
2, isolate the air method with wet quilts and other refractory or non-combustible materials covered in the surface of the burning material, isolate the air, the fire will be extinguished. 3, to prevent the spread of the law will be near the fire of flammable and combustible materials, from the burning area to transfer away; combustible and combustion materials and combustion area to isolate; to prevent the burning items are scattered to prevent the spread of combustion.
The initial stage of the fire, if it occurs in the home, can be used to soak the wet quilt, sacks, etc. to cover, but also can make the fire extinguished. Why is this? We burn vegetables at home when the frying pan caught fire.
As long as you quickly use the lid to cover the frying pan, and then put the pan away, it will be fine.
This is because the lid separates the burning oil from the air, and the oil doesn't get enough air, so it doesn't get the necessary oxygen, without which the oil can't continue to burn.
By the same token, the use of wet quilts, sacks, etc. to cover the fire of the burning things, and will burn all the things covered, but also to prevent the entry of oxygen, so that the fire is extinguished. But against the incipient fire, the key is "fast", can not make the fire have the opportunity to expand and spread.
3. The correct use of fire extinguishers and precautions
The use of fire extinguishers and precautions The use of fire extinguishers and precautions There are many types of fire extinguishers, suitable for extinguishing different types of fires, the use of different methods, the common are: (1) Portable Foam Extinguishers Foam extinguishers are suitable for extinguishing the oil and the general material of the incipient fire.
When using, hold the fire extinguisher with your hand to the ring, smooth and fast to the fire, do not carry, horizontal take. When extinguishing the fire, hold the ring with one hand, hold the bottom edge of the tube with the other hand, turn the fire extinguisher upside down, the nozzle is aimed at the source of the fire, and shake it vigorously for a few seconds to extinguish the fire.
Note: Do not point the lid and bottom of the fire extinguisher at the human body to prevent the lid and bottom from popping out and hurting people. Do not spray with water at the same time, so as not to affect the fire extinguishing effect.
When fighting electrical fires, try to cut off the power supply to prevent electric shock. (2) portable carbon dioxide fire extinguishers carbon dioxide fire extinguishers are suitable for extinguishing precision instruments, electronic equipment and electrical appliances below 600 volts of the initial fire.
Portable carbon dioxide fire extinguishers have two ways to use, namely, handwheel and duckbill type. Handwheel type: one hand holding the nozzle handle, the other hand tear off the seal, the handwheel will be rotated in the counterclockwise direction, open the switch, carbon dioxide gas will be sprayed.
Duckbill type: hold the nozzle handle with one hand, the other hand pull out the safety pin, the duckbill on the handrail down, you can extinguish the fire. Note: When extinguishing the fire, the person should stand in the upwind place.
The hand holding the spray canister should be held at the gel nozzle to prevent frostbite. After indoor use, ventilation should be strengthened.
(3) portable dry powder fire extinguishers dry powder fire extinguishers suitable for fighting oil, combustible gases, electrical equipment and other incipient fires. When used, first open the safety pin, one hand holding the nozzle, aimed at the source of the fire, the other hand pull the ring, you can extinguish the fire.
(4) portable "1211" fire extinguisher "1211" fire extinguishers are suitable for fighting oil, instruments and cultural relics archives and other valuables of the initial fire. Use, first tear off the aluminum seal, pull out the safety pin, one hand holding the bottom of the fire extinguisher, the other hand holding the pressure switch, the nozzle aimed at the source of the fire jet, release the pressure handle, jet that is, stop.
(5) small household fire extinguishers Household fire extinguishers are suitable for extinguishing small fires in the kitchen, living room, indoors, there are two types of spraying and throwing. Use: Jet type - press the spring button on the top of the fire extinguisher, the nozzle will be aimed at the fire, spray fire.
Throwing type - just throw it in the fire, the container is broken, the dry powder is released to extinguish the fire.
4. General knowledge of the use of fire extinguishers , .
Foam fire extinguishers to adapt to the fire and the use of
Scope of application:
Suitable for fighting general class B fires, such as oil products, grease and other fires, can also be applied to class A fires, but can not fight class B fires in the water-soluble flammable, flammable liquids such as alcohols, esters, ethers, ketones and other substances fires; also can not fight charged equipment and class C and class D fires.
Usage: Hand-held cylinder on the upper part of the ring, quickly run to the fire. It should be noted that the fire extinguisher should not be excessively tilted, not to mention horizontal or upside down, so as not to mix the two agents and sprayed in advance. When the distance from the fire point of about 10 meters, you can turn the cylinder upside down, a hand holding the ring, the other hand to hold the bottom ring of the cylinder, the jet aimed at the burning material. When fighting combustible liquid fire, such as has been flowing combustion, the foam will be sprayed from far and near, so that the foam completely covered in the burning liquid surface; such as burning in the container, the foam should be shot to the inner wall of the container, so that the foam along the inner wall of the flow, and gradually cover the surface of the liquid on fire. Do not spray directly against the liquid surface, so as to avoid the impact of the jet, but the burning liquid scattered or flushed out of the container, expanding the scope of combustion. When fighting solid material fire, the jet should be aimed at the most violent burning. With the shortening of the effective jet distance when extinguishing a fire, the user should gradually approach the burning area and always spray the foam on the burning material until it is extinguished. When used, the fire extinguisher should always be inverted state, otherwise it will interrupt the spray.
(Portable) foam fire extinguishers should be stored in a dry, cool, ventilated and easy to access place, not near the high temperature or may be exposed to the sun, in order to prevent the carbonic acid decomposition and failure; winter to take anti-freezing measures to prevent freezing; and should be often wiped out the dust, unclogging the nozzle, so as to keep it open.
- Cart type foam fire extinguishers to adapt to the fire and the use of
Its adaptive fire and portable chemical foam fire extinguishers are the same.
Usage: When used, generally operated by two people, the first fire extinguisher quickly pushed and pulled to the fire scene, stopping at about 10 meters from the fire point, by a person after the application of spray hose, hands holding the gun and aimed at the combustion; the other first counterclockwise rotation of the handwheel, will be the screw up to the highest position, so that the cap is open to the full, and then tilt the cylinder back, so that the tie rod touches the ground, and will be the valve handle Rotate 90 degrees, you can spray foam to extinguish the fire. If the valve is installed at the gun, the person responsible for operating the gun to open the valve.
5. What are the four steps of the use of fire extinguishers
1, fire extinguishing, remove the fire extinguishers, hand-held or shoulder fire extinguishers to quickly run to the scene of the fire, in the distance from the burning place of 5 meters or so, with one hand to hold the bottom of the bottle, a hand to hold the pressure handle, and then gently placed on the ground, safety reasons to the nozzle to the ground at 45 degrees, the use of the first to pull out the seals and keys.
2, the dry powder fire extinguisher worn in the pressure handle key removed, only removed to use.
3, extinguish the fire to stand in the fire upwind, be careful not to adjust the direction of the use of the hand to adjust, the hand also do not touch the nozzle, must remember. Then the nozzle to the place on fire, with a strong hand to press the pressure handle, after a while you can put out the fire. One hand should always press down the pressure handle, can not release, otherwise it will interrupt the jet.
4, at a distance of 2-5 meters from the flame (depending on the size of the flame, outdoor use to occupy the windward direction), one hand forcefully press down on the pressure handle, a hand holding the nozzle, so that the nozzle is aimed at the most intense combustion, sweeping left and right, as far as possible, so that the dry powder to cover the combustion zone, until the fire is completely extinguished.
Extended information
Portable dry powder fire extinguishers attention to the problem, with the fire extinguisher, to avoid impact on the liquid surface, in order to prevent the fire splash. Fire extinguishers once opened for use, can not be saved for reuse, must go to the professional fire equipment business department to re-infuse gas to save the use. Should strengthen the inspection, check whether the pressure is in line with the requirements, nozzle with or without damage, the appearance of any obvious corrosion and so on.
Portable dry powder fire extinguisher jet time is very short, so before using the powder spray hose to the flame before opening the valve. Portable dry powder fire extinguisher jet distance is also very short, so when used, the operator to ensure their own safety should be as close as possible to the source of the fire. And according to the burning range to choose the appropriate specifications of the fire extinguisher, if the burning range is large, the fire extinguisher specifications are small, it will be a foregone conclusion.
The types of fire extinguishers can be divided into its mobile mode, portable and cart. According to drive the power source of the extinguishing agent can be divided into, storage cylinder type, storage pressure, chemical reaction type. According to the charge of the extinguishing agent can be divided into foam, dry powder, carbon dioxide and so on.
