In the event of a fire, take the fire extinguisher nearby. Take a hand-held fire extinguisher, pull out the safety plug with the other hand, shake it up and down several times, and stand 3-4 meters upwind from the fire. Hold the pressing handle and spray it at the root of the fire source and keep pushing forward until the fire goes out.
(1) Pressurized injection at the root of the flame, not too high
(2) Spray 2 to 3 meters from the flame
(3) Stand in the upper wind direction of the flame and spray
(Short note: 2-3 meters upwind from the fire root spray)
