The Mace Guard Alaska Bear Spray is a formulation of Oleoresin Capsicum (OC) Bear Safe Formula, a natural ingredient derived from hot peppers that is EPA regulated. Upon contact, OC Pepper causes the membranes of the eyes, nose and lungs of a bear to engorge and the result is the temporary loss of sight, restriction of breathing and a painful burning sensation. To use Guard Alaska Bear Mace Spray, pull off the orange safety wedge on the top of the grip. Be ready to spray the bear by pressing down on the actuator button on the top of the hand grip. Store bear repellent spray in cool dry areas away from heat, flame or strong sunlight. Do not store where temperature may exceed 120AdegF/50AdegC such as an enclosed vehicle, which can cause spray canisters to leak from over pressurization and fail to function properly. Do not store bear repellent in cold environments below 32AdegF/0AdegC, which can cause depressurization and the loss of effective range.Features3 year shelf life Up to...
