Field First Aid
Injuries turn survivable trips into emergencies. First aid skill is calm triage: life threats first, then stabilise, then plan evacuation.
Scenario
Remote trail; partner with deep calf laceration; two hours to trailhead.
Best first move: Bleeding control
Direct pressure and packing beat clever herbal folklore. Then decide: can they walk with help, or do you need to signal for rescue?
Why it matters
The PSR calculator treats first aid as a gating skill—because a broken ankle or heat stroke ends self-rescue fast.

FAQ
Should I drink alcohol for cold?
No. It increases heat loss and impairs judgement.
When do I use a tourniquet?
Only for life-threatening limb bleeding you cannot control with pressure—and only if you know how. Note the time and seek emergency care.
