Store your pepper spray in cool dry area away from heat, flame or strong light. Do not store it in an environment where the temperature may exceed 120 degrees F (50 degrees C) such as an enclosed vehicle. The Pepper Spray cartridge may leak from over pressurization and fail to function properly. Do not store unit in a cold environment under 32 degrees F (0 degrees C). This may cause depressurization and the loss of effective range.
