Is the fire-fighting equipment in the community broken, is it the industry Committee or the property management?

The maintenance fee is paid by the property.

facility management

First, it is placed at a fixed point and cannot be moved at will. The second is to conduct a general survey of fire extinguishers and change their dressing regularly, and regularly check fire-fighting equipment to ensure that it is in good condition. The third is personal management. Check the fire-fighting equipment frequently, and report to the leader immediately if it is lost or damaged, so as to ensure that the management responsibility of fire-fighting equipment is assigned to people.

There are three common portable fire extinguishers: portable dry powder fire extinguishers, portable carbon dioxide fire extinguishers and portable halogenated fire extinguishers, among which halogenated fire extinguishers have been discouraged because of their impact on environmental protection.

In hotels, restaurants, theaters, hospitals, schools and other public gathering places, ammonium phosphate dry powder fire extinguishers (commonly known as "ABC dry powder fire extinguishers") and carbon dioxide fire extinguishers are mostly used, while sodium bicarbonate dry powder fire extinguishers (commonly known as "BC dry powder fire extinguishers") and carbon dioxide fire extinguishers are mostly used in gas stations and other places.

According to the nature that carbon dioxide can neither burn nor support combustion, people have developed various carbon dioxide fire extinguishers, including foam extinguisher, dry powder fire extinguishers, liquid carbon dioxide fire extinguishers and wind fire extinguishers.

equipment selection

1, to put out Class A fire, that is, solid combustion fire, water-type, foam, ammonium phosphate dry powder and halon fire extinguishers should be selected. Class A fire: refers to solid material fire. This kind of substance often has the nature of organic matter, and it can generally produce glowing embers when burning. Such as wood, cotton, wool, hemp, paper fire, etc.

2. Dry powder, foam, halon and carbon dioxide fire extinguishers should be used to put out Class B fires with polar soluble solvents (it is worth noting here that chemical foam extinguisher can't put out Class B fires with polar soluble solvents, because chemical foam will be quickly absorbed when it comes into contact with organic solvents, which will make the foam disappear quickly, thus failing to put out the fire. Alcohol, aldehyde, ketone, ether and ester are all polar solvents). ?

Class B fire: refers to liquid fire and meltable solid fire. Such as gasoline, kerosene, crude oil, methanol, ethanol, asphalt, etc.

3. To put out Class C fire, that is, gas burning fire, dry powder, haloalkane and carbon dioxide fire extinguishers should be used. Class C fire: refers to gas fire. Such as coal steam, natural gas, methane, ethane, etc.

4. Fighting Class D fires, that is, metal burning fires, as far as China is concerned, there is no finalized fire extinguisher product. There are mainly powder graphite fire extinguishers and special dry powder fire extinguishers to put out metal fires abroad. Dry sand or cast iron foam can be used to extinguish the fire when the domestic fire extinguisher and extinguishing agent beads have not been finalized. Class d fire: refers to metal fire. Such as potassium, sodium, magnesium, titanium, aluminum-magnesium alloy, etc.

5. For class E fire fighting, ammonium phosphate dry powder and halon fire extinguisher should be selected. Class E fire: refers to the fire of charged objects. Such as generator room, transformer room, power distribution room, instrument room, computer room, etc. , can't power off or power off in time.

6. Extinguish F-class fires, that is, fires of cooking materials (animal and vegetable oils) in cooking utensils. Avoid water, foam and water-containing substances when extinguishing the fire, and use suffocation to extinguish the fire by isolating oxygen.
