Wind Conditions
Wind speed and direction can affect the efficiency of bear spray. If the wind is blowing in the user's face, the spray will contaminate the user and not the bear. In addition, if there is a crosswind, the bear may not receive a full application of the spray. Prior to deployment of the spray, the user should move to where the wind direction is more favourable, if possible.
- Accidental Contamination
The inflammatory properties of the bear spray will affect humans in a similar way as bears. A person contaminated with bear spray will experience irritation and swelling of the mucous membranes of the eyes, nose and lungs. The eyes will involuntarily close and tear, the nose will run profusely and coughing will result. To de-contaminate upon an accidental contamination, the person should:
- Wash all affected areas with cool clean water;
- Remove contact lenses;
- Wash all contaminated clothing as soon as possible;
- Be aware of hypothermia in cool weather conditions; and
- Take short shallow breaths to avoid breathing in the spray.
It may take up to 20 minutes before relief from the symptoms are felt. If symptoms persist, the individual should seek medical attention.
- Transportation and Storage
When transporting bear spray, the carrier should ensure that the safety clip is on the trigger to prevent an accidental discharge. Bear spray should not be transported in the passenger compartment of a vehicle. On an aircraft, the pilot must be advised that bear spray is being transported. The bear spray should be placed in an airtight container and stored in an outside compartment of the aircraft.
When storing bear spray, the following guidelines should be used:
- Do not place cans near a heat source;
- Do not store at temperatures above 50 degrees Celsius;
- Do not store at temperatures below -10 degrees Celsius; and
- Do not puncture the can.
- Other Considerations:
- All bear spray cans have an expiry date and a shelf-life of about four years. Do not use expired cans.
- Replace bear spray as soon as practical after being deployed. Even one use can deplete half the contents.
Bear spray must be carried so it is easily accessible, preferably in a holster worn on a belt or pack.
