1. Lift dry powder fire extinguisher
Extract the fire extinguisher upside down to the fire scene twice, remove the safety plug, hold the nozzle to the flame root with one hand, and press down the handle with the other hand. When extinguishing the fire, it should be thrown out once. Outdoor use should stand on the fire source of the tuyere, from near to far, left and right sweep forward, do not let the flame back.
2. Portable 1211 extinguisher
First remove the safety pin, then open the press handle with one hand, hold the handle of the trumpet spray bucket with the other hand, and grasp the open press
The use of fire extinguisher can be ejected. (At present, the country is gradually restricting the use of halides, mainly because of the atmospheric pollution and harmful to human health.) Now co2 fire extinguishers are gradually replacing 1211 fire extinguishers, using the same methods as 1211 fire extinguishers. But when using CARBON dioxide you must be careful not to hold the nozzle or touch the mouth to prevent frostbite.
3. 35kg wheeled dry powder fire extinguisher
Two men operate, one takes off the spray gun, unfurls the hose, and pulls the trigger; The other man pulls out the pin of the trigger mechanism and quickly opens the trigger mechanism of the fire extinguisher.

When putting out a fire, put the foam extinguisher upside down, the foam can be ejected and cover the fire to achieve the purpose of putting out the fire. It is applicable to extinguish the fire of oil barrel, pipeline and ground. Does not apply to electrical equipment and precision metal products fire.
5. Carbon tetrachloride fire extinguisher
Carbon tetrachloride, after gasification, is a colorless, transparent, non-conductive, denser gas than air. To extinguish the fire, turn the fuselage upside down with the nozzle down and turn open the hand valve to spray the flame out. Applicable to extinguish the fire of electrical equipment and valuable instruments and equipment. Carbon tetrachloride is toxic, so users should stand in the upper air tuyere. In the room, after the fire should be timely ventilation.
6. Carbon dioxide extinguisher
Carbon dioxide is a nonconductive gas, denser than air, and liquid at high pressure inside a cylinder. When extinguishing a fire, just flip the switch and carbon dioxide is sprayed onto the fire with airflow, isolating air and extinguishing the flame. Suitable for small area fire in precision instrument, electrical equipment and oil laboratory. When carbon dioxide changes from liquid to gaseous state, it absorbs a lot of heat and has a very low temperature (up to -80℃). Frostbite should be avoided. In the meantime, although carbon dioxide is non-toxic, it has asphyxiation effect, should avoid inhalation as far as possible.
