Bear spray is potent because it contains capsaicinoids, the compounds that give peppers their heat. When the trigger is pressed, the spray dispenses in a fog, rather than a stream, to quickly interact with the mucous membranes of the animal’s face and lungs to slow or stop an attack.
Depress actuator tab for burst of spray (Fig. 2).Aim at face and eyes of bear. Press trigger for 2 seconds in order to create a barrier of spray between you and the bear. Stop to evaluate the impact of wind and other factors and adjust your aim if needed before spraying again.
