Proper Storage of Bear Spray
Bear spray is a non-lethal pepper deterrent containing active ingredients derived from capsicum. Capsicum derivatives are an extreme irritant of the skin, eyes, nose, throat, and lungs of bears, humans, and other mammals. Bear spray containers are under high pressure and are extremely flammable. If punctured, bear spray canisters may become flying missals with erratic flight paths. When not being used in the field, bear spray must be stored properly to avoid injury or irritation from accidental exposure.
