18018218119At present, there are two common types on the market: water-based fire extinguishers and dry powder fire extinguishers. Water-based fire extinguishers contain hydrocarbon surfactants, fluorocarbon surfactants, flame retardants and additives. Mist water mist can quickly evaporate heat and reduce fire temperature. Its combustion state is combustible materials, temperature and oxygen, all of which cannot be reduced.
Surfactant can quickly form a water film on the surface of combustibles to isolate oxygen and participate in the fire extinguishing process, so as to realize rapid fire extinguishing. Water based fire extinguisher is a kind of physical and chemical fire extinguisher with the characteristics of environmental protection, rapid penetration and reburning resistance. Compared with other fire extinguishers, it has better flame retardant performance. The utility model has no impact on the environment and can be used indoors, outdoors and in strong wind environment.
How to use water-based fire extinguishers?
The utility model has the characteristics of corrosion prevention, durability, environmental protection, fast fire extinguishing speed, flame retardance, reburning resistance, no penetration, no strong wind inside and outside the room, and so on, and is not influenced by strong wind inside and outside the room. The water based fire extinguishers are divided into water based water mist extinguishers, water purifier extinguishers and water foam extinguishers. Let's see how to use water-based fire extinguishers correctly with Xiaobian:
1： Take the fire extinguisher to the site, about 6-10m away from the burning material, and then pull out the safety pin.
2： Hold the open hold down rod with one hand and the water gun with the other hand. When opening the pressure device, please press down and hold it tightly. After the fire extinguisher is sealed, foam gun is sprayed.
After the foam is sprayed, the ignition point is aligned with the spray gun, so that the fire extinguisher is vertical to the ground, and can not lie down or stand upside down.
The above describes the use method of water-based fire extinguishers. All fire extinguishers adopt the same method, but the composition of different types of fire extinguishers is different. In application, attention should be paid to distinguish the nature of fire extinguishing and the use of fire extinguishers, so as to avoid accidental dangerous problems.
Precautions for using water-based fire extinguisher
1. First check whether the appearance of water-based fire extinguisher pressure gauge is damaged or deformed, and replace it if damaged; 2. Check whether the pointer of the fire extinguisher pressure gauge points to the green area, that is, the air pressure in the green area is normal; 3. Whether the nozzle of the fire extinguisher is deformed, cracked, damaged or replaced; 4. Check whether the spray hose is unblocked and whether the handle, valve body and other metal parts are deformed, damaged and corroded; 6. Whether the safety pin and lead seal are intact, and whether there is a blowout nozzle; 7. The fire extinguisher is seriously deformed and the cylinder is seriously corroded (a large number of paint falls off, and the corrosion area is greater than or equal to one third of the total area); Fire extinguishers with rusty connecting parts and cylinder bottom shall be scrapped; 8. The rubber and plastic parts of the fire extinguisher shall not be deformed, faded, aged or damaged, otherwise they shall be replaced.
