Acid and alkali fire extinguishers.

The acid and alkali fire extinguisher uses the mixture of two kinds of liquid medicine installed in the cylinder to produce a certain amount of gas, and the gas generates pressure to spray out the aqueous solution to extinguish the fire.

It is mainly suitable for fighting wood, textiles, cotton and linen, paper, grain and grass and other general solid substances, and is not suitable for fighting oil, electrical, light metal and combustible gas fires.

The structure of the acid and alkali fire extinguisher is mainly composed of a barrel body, a sulfuric acid bottle, a bottle clamp and a nozzle. The sulfuric acid bottle is fixed by a bottle clamp, and the bottle is filled with concentrated sulfuric acid, and the bottle mouth is plugged with a lead stopper to prevent the sulfuric acid from absorbing water and diluting it from mixing with the liquid medicine outside the bottle. The cylinder is filled with an aqueous solution of sodium bicarbonate and there is no foaming agent.

When using a fire extinguisher. Turn the cylinder upside down, shake it up and down several times, and do not point the simple cover or the bottom part of the cylinder towards the human body to prevent blasting and injury. Remember not to rotate the lid before spraying the liquid to avoid injury.

2) Dry powder fire extinguisher, which is filled with powdered ammonia phosphate, can extinguish combustible gas, electrical, oil, wood, cotton wool and other types of fire.

2. How to use fire extinguishers.

The use of the above two fire extinguishers is the same, the fire extinguisher is brought to the upwind of the fire near the first place (1) pull out the safety pin (2) hold the nozzle tightly with one hand, (3) pinch the pressure handle with the other hand, (4) the nozzle is aimed at the root of the flame to strafe.

3) Precautions for participating in fire fighting.

A fire ground is a place with a large number of people and complex situations.
