Fire equipment refers to the equipment used for fire fighting, fire prevention and fire accidents. Professional fire-fighting equipment. The most common fire equipment: fire extinguisher, it can be divided into three types according to the pressure type of driving fire extinguisher: 1. A fire extinguisher driven by the pressure of compressed or liquefied gas released by a cylinder on the extinguisher. 2. Pressure storage extinguisher. A fire extinguisher driven by the pressure of compressed gas or fire vapor in the same container. 3. Chemical reaction extinguisher. A fire extinguisher that is driven by the pressure of the gas produced by a chemical reaction in the extinguisher. Equipment management One is fixed point, can not move at will. Second, the general survey of the fire extinguishers, regular inspections of fire equipment, to ensure that in good condition. Third, appoint people to manage. Frequently check fire equipment, found lost, damaged should immediately report to the leadership timely supplement, to achieve the fire equipment management responsibility to the people. There are three common portable fire extinguishers: portable dry powder fire extinguishers, portable carbon dioxide fire extinguishers and portable halogenated fire extinguishers, halogenated fire extinguishers because of the impact on environmental protection, has not advocated the use. In hotels, restaurants, cinemas and theatres, hospitals, schools and other public gathering places use mostly ammonium phosphate dry powder fire extinguishers (commonly known as "ABC dry powder fire extinguishers") and carbon dioxide fire extinguisher, in the place such as gas, LPG stations are using sodium bicarbonate dry powder fire extinguishers (commonly known as "the BC dry powder fire extinguishers") and carbon dioxide fire extinguisher. According to the nature that carbon dioxide can neither burn nor support combustion, various carbon dioxide extinguishers have been developed, including foam extinguishers, dry powder extinguishers and liquid carbon dioxide extinguishers, and wind extinguishers. Equipment selection 1. Water type, foam, ammonium phosphate dry powder and halogenated alkyl extinguisher should be used for class A fire, that is, solid combustion fire. Class A fire: refers to A solid material fire. The substance is often organic in nature and generally produces glowing embers when burned. Such as wood, cotton, wool, linen, paper fire, etc. 2. Saves a class B as liquid fire and melted solid material should be chosen type dry powder, foam, halogenated, carbon dioxide fire extinguisher (here it is important to note that chemical foam extinguisher fire cannot destroy the class B soluble solvent polarity, because chemical foam and organic solvent by touch, foam will quickly be absorbed, make bubble disappear very quickly, so you can't play the role of fire extinguishing. Alcohols, aldehydes, ketones, ethers, esters and other belong to a polar solvent). Class B fire: refers to liquid fire and melting solid material fire. Such as gasoline, kerosene, crude oil, methanol, ethanol, asphalt and so on. 3. Dry powder, halogenated alkane and carbon dioxide extinguishers should be used to fight class C fire, that is, the fire of gas combustion. Class C fire: gas fire. Such as coal gas, natural gas, methane, ethane, etc. 4. Fight D type fire is the metal burning fire, as far as the situation in our country, has not finalized the fire extinguisher products. The foreign extinguishers of type D mainly include powder graphite extinguishers and special dry powder extinguishers for metal fires. In the domestic has not finalized the production of fire extinguishers and extinguishing agent beads can be used dry sand or cast iron foam fire. Type D fire: metal fire. Such as potassium, sodium, magnesium, titanium, aluminum magnesium alloy. 5. Ammonium phosphate dry powder and halogenated alkyl fire extinguisher should be used to extinguish class E fire. Class E fire: a fire involving a charged object. Such as generator room, transformer room, power distribution room, instrument room and electronic computer room in the combustion can not be timely or not suitable for power supply of electrical equipment live combustion fire. 6. Fight F fire, that is, the cooking products (animal and vegetable oils) fire in cooking utensils. Do not use water, foam and water - borne substances when extinguishing fire.
