How to use fire extinguishers
CO2 fire extinguisher 60
1. Lift the fire extinguisher and move it 3-5 meters upwind of the fire site;
2. Remove the safety pin and place the metal conduit of the horn at a 70-90 degree angle to the bottle body;
3. Due to the large amount of heat absorption required for carbon dioxide to change from liquid to gas, do not directly touch the horn and spray hose without protection. Instead, hold the grip with one hand and hold the bottom of the bottle with the other hand, aiming to spray left and right at the root of the fire source. If used in a narrow area, try to evacuate quickly after use to prevent suffocation.
