How to Avoid Needing SAR

- Know your physical limitations.
- Test your equipment under controlled conditions.
- Protect against Giardia (and other causes of infectious diarrhea).
- Keep the team together at all times.
- Be aware of the weather.
Avoid the potential hazards of nature. These include lightning, cold weather (hypothermia and frostbite), dehydration (situations of heat, cold, high altitude, strenuous exertion), snow- and sun-blindness, high altitude-related illness, and heat-related illness.
If You Become Lost
- Unless you know exactly what you are doing and where you are going, stay put.
- Try to make noise
- Determine your orientation.
- Find a shelter.
- If you are on the move, leave clues for rescuers.
- If it will become cold, build a fire.
If You're With Someone Who Becomes Lost
- Holler or whistle and listen for a response.
- Conduct a brief limited search in groups of two persons.
- Mark the location where the person was last seen on a map and on the ground.
- Return to the road or trailhead, marking your path to assist rescuers in finding the “point last seen.”
- Call 911.
- Remain at the trailhead in case the lost person follows you out, and to assist the search and rescue team.
