When using a fire extinguisher, you should stand at a distance of 2 meters from the fire source and pull out the safety pin, right?
Dry powder extinguishers should be waved before use. Next, stand 4-6 meters away from the fire source, pull the safety pin, press down the handle, hold the leather tube, select the upwind position or the cross wind direction, close to the fire point, and aim at the source of fire to extinguish the fire. If you have any questions, please feel free to ask questions.
Before using a fire extinguisher, you should see whether the pressure gauge is normal or not. Green is normal pressure, red pressure is not enough, yellow is too much pressure.
