Dry powder fire extinguishers are enough for the kitchen. There are generally no important materials in the kitchen. The main causes of common fires are electricity, oil, liquefied gas and gas. Dry powder fire extinguisher is enough. Dry powder fire extinguisher is powered by carbon dioxide gas or nitrogen, and uses compressed carbon dioxide to blow dry powder (mainly containing sodium bicarbonate) to extinguish the fire. But if there is a fire, it should be handled as appropriate. If it cannot be put out, please evacuate in time and call the police.

How to use fire extinguishers correctly

1. The fire extinguisher should be kept in a horizontal state, and it should be shaken up and down several times before use to loosen the dry powder inside and avoid accumulation.

Next, you need to unplug the safety pin on the fire extinguisher. There is a metal ring on it. After pulling it out, the powder inside can be sprayed out.

3. Aim at the fire source, 5 meters away from it. This is an effective range. Hold the front end of the nozzle with the other hand and grasp the direction. Lift the handle of the fire extinguisher with the other hand, press the switch of the fire extinguisher, and directly spray dry powder to extinguish the fire.

Besides dry powder fire extinguishers, what types of fire extinguishers can you choose?

1, portable foam extinguisher

Suitable for extinguishing the initial fire 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.

However, careless use of foam extinguisher will cause the lid and bottom to pop up and hurt people; If you spray water at the same time, it will affect the fire extinguishing effect; When putting out electrical fire, it is easy to cause people to get an electric shock, which has certain risks.

2, portable carbon dioxide fire extinguisher

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. The handwheel needs to hold the handle of the spray barrel with one hand, tear off the lead seal with the other hand, turn the handwheel counterclockwise and turn on the switch, and carbon dioxide gas will be sprayed; Duckbill requires one hand to hold the handle of the spray gun, the other hand to pull out the safety pin, and press the duckbill on the handle to extinguish the fire.

However, attention should be paid to fire fighting, and personnel should stand in the windward; The hand holding the nozzle should be held at the rubber mouth to prevent frostbite; Ventilation should be strengthened after indoor use, otherwise it will suffocate people.
