What Are Different Types of Fire Apparatus?

Fire fighting equipment refers to equipment used for fire extinguishing, fire prevention and fire accidents. Equipment for professional fire fighting. The most common fire-fighting equipment: fire extinguishers, which can be divided into three categories according to the type of pressure that drives the fire extinguishers: 1. Gas storage fire extinguishers. Fire Extinguisher A fire extinguisher driven by the pressure of a compressed or liquefied gas released from a gas cylinder on the fire extinguisher. 2. Storage pressure fire extinguisher. The fire extinguisher is driven by the pressure of compressed gas or fire extinguishing vapor in the same container as the fire extinguisher. 3. Chemical reaction type fire extinguisher. The fire extinguisher is a fire extinguisher driven by the gas pressure generated by the chemical reaction in the fire extinguisher.

The first is to place it at a fixed point and not move it at will. The second is to regularly change the fire extinguisher and change the medicine, and regularly inspect the fire equipment to ensure that it is in good condition. The third is appointment management. Check the fire-fighting equipment frequently and report it to the leader immediately to find any loss or damage. There are three common types of portable fire extinguishers:

1. To extinguish Class A fires, that is, solid-fired fires, water type, foam, dry powder of ammonium phosphate, and halogenated fire extinguishers should be used. Class A fire: refers to a solid material fire. This substance is often organic in nature and generally produces hot embers when burned. Such as wood, cotton, wool, linen, paper fire, etc.

2. To extinguish Class B, namely liquid fires and meltable solid material fires, dry powder, foam, haloalkane, and carbon dioxide type fire extinguishers should be selected (It is worth noting here that chemical foam fire extinguishers cannot extinguish Class B polar soluble solvent fires, because When organic solvents are touched, the foam will be absorbed quickly, making the foam disappear quickly, so it cannot play the role of fire extinguishing. Alcohols, aldehydes, ketones, ethers, esters, etc. are polar solvents). Class B fire: refers to liquid fires and meltable solid material fires. Such as gasoline, kerosene, crude oil, methanol, ethanol, asphalt and so on.

3. To extinguish Class C fires, that is, gas fires, dry powder, halocarbon, and carbon dioxide fire extinguishers should be used. Class C fire: refers to gas fire. Such as coal gas, natural gas, methane, ethane and so on.

4. Fighting Class D fires, that is, metal burning fires, as far as China's situation is concerned, there are no finalized fire extinguisher products. Class D fire extinguishers abroad mainly include powder graphite fire extinguishers and dry powder fire extinguishers for metal fires. In the case of domestic production of fire extinguishers and fire extinguishing agent beads, dry sand or cast iron foam can be used for fire extinguishing. Class D fire: Metal fire. Such as potassium, sodium, magnesium, titanium, aluminum-magnesium alloys, etc.

5. To extinguish Class E fires, use ammonium phosphate dry powder and halogenated alkyl fire extinguishers. Class E fire: refers to a fire of a charged object. Such as the generator room, transformer room, power distribution room, instrument room and electronic computer room and other electrical equipment that can not be timely or should not be cut off during the burning fire.

6. Extinguish Class F fires, that is, fires in cooking utensils (fauna and fats) in cooking appliances. Do not use water, foam and water-containing substances when extinguishing fires. Use suffocation to extinguish fires with oxygen.

According to the principle of combustion, the principle of all fire extinguishing methods is to spray the extinguishing agent directly on the burning object or spray the extinguishing agent on the material near the fire source, so that it does not form a new fire point due to the heat radiation of the flame.

Fire-fighting equipment is an important weapon for mankind to fight against fire. With the rapid development of science and technology, the infiltration of multiple disciplines has brought vitality and vitality to the renewal and development of fire-fighting equipment. Fire fighting equipment involves a wide range and variety. From fire automatic control and alarm systems, fire extinguishers, fixed fire extinguishing systems, pumps, vehicles and water supply equipment, personal equipment and

Portable dry powder fire extinguisher

The fire extinguisher can be quickly carried to the fire field by hand or shoulder, and the fire extinguisher can be set down about 5 meters from the burning place. If you are outdoors, you should choose to spray in the upwind direction. If the dry powder fire extinguisher used is an external pressure storage type, the operator should hold the spray gun firmly in one hand and lift the opening ring on the gas cylinder with the other. If the cylinder is opened by hand wheel, turn it counterclockwise and turn it to the highest position, then lift the fire extinguisher. When the dry powder is sprayed out, quickly shoot at the root of the flame. If the dry powder fire extinguisher used is a built-in gas cylinder or pressure storage type, the operator should first remove the safety pin on the opening and then hold the nozzle part of the front end of the spray hose, and the other hand will open the pressure handle Press down and open the fire extinguisher to extinguish the fire. When using a fire extinguisher or a pressure storage fire extinguisher with a spray hose, always press down the handle with one hand and do not release it, otherwise the spray will be interrupted.

When dry powder fire extinguisher is used to extinguish combustible and flammable liquid fires, it should be directed at the main part of the flame. If the liquid fire being extinguished is flowing and burning, it should be aimed at the root of the flame from near to far and fired from left to right until the flame is completely extinguished. If a flammable liquid is burned in the container, the user should shake the flame at the root of the flame to cover the entire surface of the container; when the flame is driven out of the container, the user should continue to spray until the flame is completely extinguished . When extinguishing a flammable liquid fire in a container, care should be taken not to direct the nozzle to the liquid surface to prevent the impact of the jet from flaming the flammable liquid and expanding the fire, making it difficult to extinguish the fire. If the combustible liquid is burned in a metal container for too long, and the wall temperature of the container is higher than the spontaneous ignition point of the extinguished combustible liquid, it is very easy to cause re-ignition after extinguishing the fire. If it is used in combination with a foam fire extinguisher, extinguish the fire The effect is better.

When using a dry powder fire extinguisher to extinguish a solid combustible fire, it should be directed at the most violent burning position, and fired upward, downward, left and right. If conditions permit, the user can carry the fire extinguisher along the four perimeters of the burning material to spray dry powder fire extinguishing agent evenly on the surface of the burning material until the flame is completely extinguished.

--- First pull out the safety pin, then open the pressure handle with one hand, hold the handle of the horn spray bucket with the other hand, and hold the opening pressure firmly

Spray it out. The state gradually restricts the use, mainly because haloalkanes cause pollution to the atmosphere and are harmful to humans. ) Carbon dioxide fire extinguishers are gradually replacing

In retrospect, the earliest fire-fighting equipment in the world can be called from October 16, 1834, when a fire in London almost completely destroyed the ancient Westminster Palace, where the British Parliament building is located. Among the many fire watchers, there is one who is not idle and rushes to see the fire scene. He is George William Manby.
Manby was born in Norfolk. He was a young soldier, officer to captain, and head of the Yarmouth Barracks. This spare time allowed him to devote his time to the cause that strongly attracted him to save human life. Earlier, he was enthusiastic about rescue from shipwrecks. He invented the pant-shaped life buoy and was the first person to propose to use a lighthouse to flash the identification signal. Later, Manby turned his genius from marine rescue to fire rescue. When the fire broke out, he was experimenting with fire protection clothing. His most remarkable pioneering contribution was his invention of a portable compressed gas fire extinguisher, a two-foot-long, eight-inch-diameter, four-gallon copper cylinder that is essentially the same as today's fire extinguishers. He put the fire extinguisher in his specially designed trolley, and he hoped that the patrols equipped with the fire extinguisher would immediately extinguish the small fires at the fire site, thereby reducing the number of major fires.

1. Watch the truth from the outside. When purchasing fire protection products, in addition to checking whether the dealer's business license is legal, check the appearance of the fire protection product in detail.

2. Know the truth from the certificate. To see if the product has an inspection report or certification. There are 12 types of fire protection products under the compulsory product certification. There are 9 types of fire products that implement the fire product form approval system.

3. Check the authenticity online. Consumers can log on to the website of the Ministry of Public Security Fire Products Conformity Assessment Center to check and check.

4. Identify by simple testing. Such as fire emergency lighting and evacuation indication signs, anti-counterfeit red "S" ID cards are affixed on the obvious location. If the continuous power supply time is less than 90 minutes, it is an unqualified fire protection product. ^[2]
