Foam extinguisher is suitable for putting out initial fires of oil and general substances. When in use, hold the lifting ring of the fire extinguisher by hand and lift it to the fire site smoothly and quickly, instead of carrying it horizontally. When putting out the fire, hold the bail in one hand and the bottom edge of the bucket in the other, turn the fire extinguisher upside down, aim the nozzle at the fire source, and shake it hard for a few times to put out the fire.

Second, portable carbon dioxide fire extinguisher

Carbon dioxide fire extinguisher is suitable for extinguishing the initial fire of precision instruments, electronic equipment and electrical appliances below 600 volts. Portable carbon dioxide fire extinguishers can be used in two ways, namely handwheel type and duckbill type.

Three, portable dry powder fire extinguisher

Dry powder fire extinguisher is suitable for extinguishing the initial fire of oil, combustible gas and electrical equipment. When in use, first open the safety pin, hold the spray pipe with one hand, aim at the fire source, and pull the pull ring with the other hand to extinguish the fire source.

The "12 1 1" fire extinguisher is suitable for putting out the initial fire of valuables such as oil, instruments and cultural relics. When in use, first tear off the aluminum seal, remove the safety pin, hold the bottom of the fire extinguisher with one hand, and hold the knob switch with the other hand. The nozzle is aimed at the fire source to spray, and the spray will stop when the knob is released.

Five, clear water fire extinguisher

Clear water fire extinguisher is filled with clear water, and additives such as antifreeze are added. This kind of fire extinguisher puts out the fire by the principle of cooling and suffocation. Clear water can absorb sensible heat and latent heat, which has a significant cooling effect. When water is heated, it forms steam, which can reduce the oxygen solubility in the fuel area and so on. Clear water fire extinguishers are mainly used to extinguish Class A fires.
