How to use

When a dry powder fire extinguisher is used to extinguish a flammable or flammable liquid fire, it should be directed at the part of the flame. If the fire of the saved liquid is burning, it should be aligned with the root of the flame. Far, and sweep left and right until the flames are all extinguished. If the flammable liquid is burned in the container, the user should sway the left and right sides of the flame to make the sprayed dry powder flow cover the entire open surface of the container; when the flame is driven out of the container, the user should continue to spray until the flame is extinguished. . When extinguishing a flammable liquid fire in a container, care should be taken not to directly align the nozzle with the liquid surface to prevent the impact of the jet from splashing out the flammable liquid to expand the fire, which makes the fire extinguishing difficult. If the burning time of the flammable liquid in the metal container is too long, the wall temperature of the container is higher than the self-ignition point of the flammable liquid, and it is easy to cause re-ignition after the fire extinguishing. If it is combined with the foam fire extinguisher, the fire will be extinguished. The effect is better.
