STORAGE OF OC PEPPER SPRAY CANISTERS Poor storage conditions will significantly reduce the shelf life of these products resulting in the replacement of the canisters sooner than necessary or the possible use of defective products. Humidity and heat are the two most damaging factors that destroy OC canisters.

      • The canisters and grenades should be stored in a controlled atmosphere with temperatures between 60 degrees Fahrenheit to 75 degrees Fahrenheit with less than 60% relative humidity.
      • Canisters should remain sealed in their shipping containers until they are to be used or placed in a duty belt/holster.
      • Never store canisters in the trunk of a car for prolonged periods. The heat may cause the canisters to build pressure and eventually release propellant and possibly agent or OC.
