How to make the call
- 1Recognize an emergency — serious injury/illness, fire, crime, or danger; if unsure, call.
- 2Get to a safe spot and call 911 — on a cell, know it may route to a regional center.
- 3Give your LOCATION first — an address, or a detailed backcountry description with landmarks and coordinates.
- 4State the emergency — what happened, how many hurt, any hazards.
- 5Give your phone number for callback.
- 6Follow the dispatcher's instructions — including any first aid they guide you through.
- 7Stay on the line until told to hang up; send someone to flag down responders if you can.
When to use it
- Any emergency at home, at camp, or on the trail needing police, fire, or EMS.
- First-aid response — calling for help is a first step in serious ("hurry case") emergencies.
- The Emergency Preparedness and First Aid merit badges.
Common mistakes & safety
- Location is everything. Responders can't help if they can't find you — give the address or a precise backcountry description first, and know your location before an emergency.
- Stay on the line. Hanging up early can cut off life-saving instructions and delay help; wait until the dispatcher releases you.
- Backcountry: 911 may not work. No cell signal means you may need a satellite messenger, a whistle, or to send runners — plan your emergency communications before you go.
- Call for real emergencies only — false or prank calls are illegal and tie up help someone else may need.
- Send help toward you — if possible, have someone meet responders at the road or trailhead to guide them in.
Going deeper
- Where, what, number. The three things a dispatcher needs — in that order, because location is what gets help moving.
- Answering questions doesn't slow help. Dispatchers often send responders while still on the line; keep answering.
- Don't hang up. The most common mistake — the dispatcher's instructions are part of the rescue; stay on until they say go.
