The use and advantages of fire extinguishers

Before using the fire extinguisher, it is necessary to check whether the pressure is effective;

Swing the fire extinguisher up and down vigorously several times;

Remove the safety pin, hold the handle in one hand, hold the nozzle with the other hand, quickly go to the ignition point about 1.5 meters away, aim at the root of the flame, and press the pressure handle switch firmly until the fire extinguishing agent is sprayed;

Advance the fire from far and near left and right strafing forward to extinguish the fire;

Once the fire is extinguished, immediately relax the pressure handle and stop spraying the fire extinguishing agent;

It has extremely fast fire extinguishing speed. In the state of total submersion, the ultra-fine dry powder fire extinguishing agent in the form of aerosol can extinguish the fire in a limited space within more than ten seconds to tens of seconds, so as to avoid the major losses caused by the spread of fire and the secondary damage caused by the explosion and leakage of hazardous chemicals caused by the fire.

It has the advantage of extinguishing the sheltered fire source. The high temperature and large amount of toxic smoke generated by confined space fires make it difficult for firefighters to enter to find the source of the fire and extinguish it, causing the fire to spread. The total submerged fire extinguishing method does not need to find the fire source in a limited space, and the ultra-fine dry powder fire extinguishing agent can bypass obstacles in the form of aerosols, and can quickly extinguish the fire in the flooded places that can be reached, saving the time of finding the fire source. For example, on a smoke-filled ignition ship, aerosol extinguishing agents can quickly extinguish fires in complex spaces such as warehouses and prevent them from expanding.
