(1) Check whether the ambient temperature of the place where the fire extinguisher is placed is between -10 ℃ and +55℃, and shall not be exposed to the hot sun, close to the heat source or subjected to violent vibration, in case the temperature is too low and the pressure drop in the fire extinguisher will affect the injection performance. At the same time, attention should be paid to prevent the excessive temperature or violent vibration, which will make the pressure inside the fire extinguisher increase dramatically and affect the safe use of the fire extinguisher.
(2) Check whether the place where the fire extinguisher is placed is damp and affected by chemical corrosion, so as to prevent corrosion of the fire extinguisher that causes the valve not to open and reduce the service life of the fire extinguisher.
(3) Check whether the location of fire extinguisher is obvious, easy to get and safe. The passage between the trolley fire extinguisher and the protected object should be unimpeded.
