After getting the dry powder fire extinguisher, we should first check the pressure dial on the fire extinguisher and see what color area the pointer points to. There are three color areas in total, and the pointer points to the green area, indicating that the pressure is sufficient and the dry powder inside is also sufficient.The pointer points to the yellow area, indicating that the pressure is still half, naturally can be pressed out of dry powder, naturally can be used for fire suppression;The pointer points to the red zone, which means low or no pressure, which means we need to find a fire extinguisher with pressure.2. If the pressure of the fire extinguisher is sufficient, then we need to stand at the upper mouth of the fire, that is, above the downwind mouth of the fire, so that the wind cannot blow the fire towards us.3.
