タイトルまたは説明

Portable dry powder fire extinguisher, a kind of fire extinguisher, suitable for the initial fire of flammable, flammable liquid, gas and live equipment; In addition to the above types of fires, portable dry powder fire extinguishers can also be used to fight the initial fire of solid substances, but they can not fight metal burning fires.
Usage method：When extinguishing flammable and flammable liquid fires, dry powder fire extinguishers should be directed at the flame. If the liquid fire being saved is flowing and burning, they should be directed at the root of the flame from near to far, and sprayed from left and right until the flame is extinguished.
Matters needing attention：When using a portable dry powder fire extinguisher to put out a solid combustible fire, it should be sprayed at the fiercest place of combustion and sprayed up and down, left and right. If conditions permit, the user can carry the fire extinguisher along the four sides of the combustion, so that the dry powder extinguishing agent is evenly sprayed on the surface of the combustion until the flame is extinguished.
