When using a fire extinguisher, we need to follow certain operating procedures. Firstly, after discovering a fire, it is important to quickly determine the size of the fire and the type of fire source, and select the appropriate fire extinguisher. Then, operate in the order of "pulling, gripping, aiming, and scanning". Pull out, that is, pull out the safety pin of the fire extinguisher; Grip, that is, grip the nozzle and align it with the base of the flame; Aiming, that is, aiming at the source of fire; Sweeping, that is, sweeping left and right, gradually pushing forward until the flame is extinguished. During the firefighting process, it is important to remain calm, pay attention to personal safety, and avoid letting the fire spread.

Fire extinguishers, seemingly ordinary but crucial equipment, are indispensable safety guardians in our daily lives. Whether in homes, offices, or public places, fire extinguishers play a crucial role in ensuring that they can be quickly and effectively extinguished in the early stages of a fire, reducing the losses caused by the fire.
