Use method of fire-fighting equipment

1. Fire extinguisher

It can be divided into portable type and trolley type according to the moving mode; According to the power source of driving extinguishant, it can be divided into: gas cylinder type, pressure storage type and chemical reaction type; According to the filled extinguishing agent, it can be divided into: foam, dry powder, haloalkane, carbon dioxide, acid and alkali, clean water, etc. The spraying time of the agent contained in the portable fire extinguisher is within one minute, and the actual extinguishing time is only 10-20 seconds.

For example, dry powder fire extinguishers are applicable to the initial fire of flammable, combustible liquids, gases and charged equipment, and can also put out the initial fire of solid substances. When using, the handle of the portable fire extinguisher shall be quickly rushed to the fire site, and the fire extinguisher shall be put down about 5m away from the fire point. When using outdoors, pay attention to the upwind direction. Before use, turn the extinguisher upside down for several times to loosen the dry powder in the cylinder, then pull out the safety pin, hold the nozzle with one hand, lift the handle with the other hand, press down the open handle, and the dry powder will spray out automatically.

2. Fire hydrant

The fire hydrant is usually set in the fire hose box with glass door, which is composed of water gun, water hose, fire hydrant and alarm button. In case of fire, first use the key or hard object of the fire hydrant box to break the glass on the door of the box, open the door, and then quickly remove the water hose on the rack and the water gun on the spring bracket. Connect the water hose interface to the fire hydrant interface. If there is an alarm button, press the emergency alarm button. When the red indicator light on the fire hydrant box is on, send a fire signal to the control room. Turn the fire hydrant handwheel counterclockwise to extinguish the fire.
