Blisters
Clean well with an antiseptic wipe. Sterilize the point of a pin or knife with flame or an alcohol swab and gently pierce the blister. Massage the fluid out, leaving the roof of the blister intact.
Cover with a friction-reducing dressing, such as Blist-o-Ban (sammedical.com), or cut a donut-shaped piece of moleskin and place it over the blister. Fill the hole with antibiotic ointment and cover the moleskin with athletic or duct tape.

Abrasions
Scrub the wound with soap and a gauze pad or bandanna, making sure to remove all debris (warning: It’ll hurt). Rinse off all of the soap, then apply a layer of antibiotic ointment to a gauze pad and tape it in place. (You can also use a commercial pad with adhesive edges.) The pad should completely cover the wound.
Burns
Immediately plunge the burn site into cold water. Second best: Apply a water-soaked bandanna, a burn gel, or aloe vera. Continue cooling until pain has substantially subsided, then cover the burn with ointment and a gauze pad. If blisters form, prevent the blisters from popping as long as possible.
