Bear spray is an effective defensive tool because it inflames the mucous membranes of the eyes, nose and lungs. The result is a nearly total, yet temporary, loss of sight and severe restriction of breathing. To be effective, bear spray has to hit the eyes and nose of the bear.
Upon deployment, there is also a sudden, loud hissing of the spray. As a result, approaching bears have sometimes been surprised, stopping and often running away before the spray even reaches them.
Be aware that the effect of bear spray on individual bears will vary.
Follow these steps for the proper use of bear spray:
- Prepare the bear spray as soon as practical;
- Remove safety clip;
- With thumb, depress trigger;
- Spray in two to three second bursts;
- Spray directly in the bear's face; and
- Do not use the entire contents as more than one application may be needed.
