Precautions for the use of portable fire extinguishers

When the extinguished flammable liquid is burning in a flowing form, the user should aim at the root of the flame from near to far and shoot left and right, and quickly advance forward until the flame is completely extinguished.

If the flammable liquid is burning in the container, the flame should be swept from side to side, and when the flame is driven out of the container, the jet stream will follow the flame until the flame is completely extinguished. However, it should be noted that the jet stream should not be sprayed directly on the combustion liquid surface, so as to prevent the impulse of the fire extinguishing agent from flushing the combustible liquid out of the container and expanding the fire, resulting in difficulty in extinguishing the fire.

If the initial disaster of flammable solid substances is extinguished, the jet stream is aimed at the most violent place of combustion, and when the flame is extinguished, measures should be taken in time to prevent it from re-ignition.
