Most camping emergencies are predictable, and the decision that matters is usually made before the emergency starts: where you pitched, what you told someone, and whether you left when the first sign appeared. Treat the four thresholds below as absolute — crossing any one of them means stop the trip, not adjust the plan.
The hazards that actually hurt campers
| Hazard | Early sign | Prevention | First ten minutes | Leave if |
|---|---|---|---|---|
| Hypothermia | Uncontrolled shivering, fumbling hands | Dry layers, dry sleep system, eat before cold | Shelter from wind, dry clothes, warm sweet drink, into bag | Shivering stops, confusion, slurred speech |
| Heat illness | Headache, nausea, stopped sweating | 1 gal water/person/day, shade 11–3 | Shade, cool water on neck and wrists, sip electrolytes | Confusion, fainting, temperature above 104 °F |
| Lightning | 30 s between flash and thunder | Leave ridges and open water by afternoon | Move to low ground, feet together, crouch on pad | Storms forecast all night |
| Wildlife (bear) | Food unsecured, tracks near camp | Bear-safe storage 100 m from tent | Group up, speak loudly, back away, do not run | Bear returns or shows no fear |
| Water | Fast current, cold shock | Never wade above knee, unbuckle pack straps | Reach, throw, then row — never swim after | Anyone submerged more than 60 s |
| Injury / cut | Bleeding, sprain | Boots, poles, first aid on site | Direct pressure 10 min, splint, warm | Cannot bear weight or bleeding will not stop |
The 30/30 lightning rule is the one people misremember: if the flash-to-thunder gap is under 30 seconds, the storm is within 6 miles and you should already be in a safe position.
Prevention is a checklist, not a feeling
- Tell someone the plan. Exact trailhead, campsite, return time, and who to call. A written message beats a verbal one.
- Water and food before thirst and hunger. Dehydration and low blood sugar both present as bad decisions.
- Dry layer kept dry. One set of clothes that never leaves the sleeping bag.
- Camp layout. Cooking area 100 m downwind from the tent, food hung or in a canister, boots inside.
- Weather window. Check the forecast at 6 p.m. the night before; plan the exposed section for the morning.
Response: the first ten minutes
- Stop. Most injuries get worse in the ten minutes after the first one, because people keep moving.
- Fix the environment before the person. Wind, wet, and cold cause the problem; change them first.
- Treat the reversible things. Warm, dry, water, sugar, pressure on a wound, splint a joint.
- Decide: stay or go. If the person can walk and hold a conversation, you can usually move at daylight. If not, you stay and signal.
Write down the time of the incident and the person’s condition every 30 minutes. That log is what responders ask for first.
Evacuation thresholds
Leave immediately, in the dark if necessary, when any of these is true:
- Shivering stops but the person is still cold (hypothermia is now moderate to severe).
- Confusion, slurred speech, or unusual behaviour.
- A head injury with vomiting or unequal pupils.
- A fracture you cannot splint well enough to bear weight.
- Chest pain, difficulty breathing, or a wound that will not stop bleeding.
- A bear in camp that does not leave when challenged.
Night evacuation is safer than waiting when the alternative is a worsening patient. If you cannot move the person, send two people for help with a written note, and keep one person with the patient.
Signaling: three methods, in this order
| Method | Range | When to use |
|---|---|---|
| Whistle — 3 blasts, pause, 3 blasts | 0.5–1 mile | Always, from the first minute you are lost |
| Bright colours / mirror / headlamp flash | 1–5 miles in daylight | Aircraft, ridge lines, clearings |
| Satellite messenger / PLB | Global | No cell signal, injury, or worsening weather |
The universal distress signal is three of anything — three whistle blasts, three fires, three flashes. Cell phones are for the trailhead, not the backcountry; battery dies and coverage ends exactly where you need it.
If you are lost: stop, shelter, and stay put once you have signalled. Moving while lost usually widens the search area. Only move if you have a clear, safe line to a road or a known landmark within an hour of daylight.
The kit that earns its weight
- Headlamp plus spare batteries (the most-used item in any emergency).
- Whistle on a lanyard, worn not packed.
- Blister kit, tape, gauze, antiseptic, gloves.
- Emergency blanket (reflective, 2 oz) and a fire starter.
- Waterproof matches or lighter in a sealed bag.
- Knife or multitool.
- 24 hours of extra food and 1 L extra water.
- Any personal medication, plus a written list.
Total weight: about 1.5 lb. That is the difference between a bad night and a rescue.
What this means for the rest of your trip
Safety is not a separate kit; it is the sum of the site you chose and the plan you left behind. Read the campsite selection guide before you pick a pitch, the tent guide for shelter that survives wind, and the weather guide when the forecast is uncertain. If you are camping with children, the family camping guide covers supervision ratios and briefing.
