Cooling a burn properly, covering it, and stopping a blister before it ends the trip.
What you need
- Clean cool water, as much as you can spare
- Non stick dressings and a roll of gauze
- Plastic cling wrap, which makes a good clean burn cover
- Moleskin, blister pads or strong tape
- A small pair of scissors
- Pain relief from your own kit
How: a burn
- Stop the burning. Get the person away from the fire, smother flaming clothing, pull off anything hot that is not stuck to the skin.
- Cool the burn under cool running or poured water for at least ten minutes. Twenty is better. Cool the burn, keep the rest of the person warm.
- Take off rings, watches and tight clothing near the burn before it swells.
- Cover it loosely with a non stick dressing or a layer of cling wrap laid on, not wrapped tight.
- Leave blisters on a burn whole. They are the best dressing there is.
- Give pain relief and fluids, and watch for shock: pale, cold, clammy, fast pulse.
How: a blister
- Stop the moment you feel a hot spot. A hot spot fixed in two minutes saves a week.
- Dry the skin and put tape or moleskin over the hot spot, smooth, with no wrinkles.
- If a blister has formed and is small, leave it whole and pad around it with a ring of moleskin.
- If it is big and will burst anyway, clean it, drain it at the edge with a flamed or wiped needle, leave the roof on, and cover it.
- Change wet socks, fix the lacing, and deal with what caused it.
Do and don't
Do
- Cool a burn even if you only reach water later. It still helps for a while after.
- Keep feet dry and change socks at lunch on a long day.
- Tape known trouble spots in the morning before they start.
Don't
- Do not put ice, butter, grease, toothpaste or ointment on a fresh burn.
- Do not pull off cloth that is stuck in a burn.
- Do not peel the roof off a blister.
Watch for
Danger
- Get help for any burn bigger than the person's palm, any burn to the face, hands, feet, groin or over a joint, and any burn that is white, leathery or has no feeling.
- Singed nose hair, soot around the mouth, a hoarse voice or trouble breathing after a fire means the airway may be burned. That is an emergency.
- Red streaks, pus, spreading heat or a fever from a burn or blister means infection. Head out.
Notes
Most camp burns come from a pot of boiling water knocked off a stove, not from the fire. Keep the stove low, stable and away from where people walk.
This card is not a first aid course. A real one, with hands on practice, is worth every hour.
