First aid, by priority

A first aid kit isn't a box of band-aids. Experts organize it by severity: first what saves a life, then what prevents complications. And they keep repeating one idea: gear without training is of little use.

Training first

Expert guides are blunt about it: owning gear doesn't make you prepared. A first aid course of a few hours, like those offered by the Red Cross and many local governments, teaches you CPR, bleeding control and how to treat a burn. That takes up no space in your bag.

Rule of thumb

Don't store anything you don't know how to use. Advanced items like tourniquets, suture kits or airways can cause harm in untrained hands.

Level 1: what saves a life

With little space, experts prioritize the most serious problems: bleeding and breathing.

  • Pressure bandage, also called an Israeli bandage, to stop heavy bleeding by pressing on the wound.
  • Sterile gauze, plenty of it, for packing and pressure.
  • Nitrile gloves, two pairs. They protect the injured person from your hands and you from their blood.
  • Trauma shears to cut clothing. Don't use your knife.
  • Tourniquet, only if you've learned to apply one. It's the most effective tool for severe bleeding from an arm or leg.
  • Emergency blanket: an injured person who isn't moving loses heat very quickly.

Level 2: everyday wound care

  • Band-aids in several sizes, at least ten.
  • Wound closure strips for small cuts.
  • Blister dressings or moleskin.
  • Medical paper or silk tape. Duct tape is not for wounds.
  • Elastic bandage and rolled gauze.
  • Single-dose saline, to rinse wounds and eyes.
  • Antiseptic: chlorhexidine or povidone-iodine.
  • Tweezers and a needle-less syringe to irrigate wounds with pressure.
  • Thermometer.

Level 3: over-the-counter medicines

Always check with your pharmacist that they're right for you, especially if you take other medication, have a chronic condition or are pregnant.

MedicineForCareful with
Acetaminophen (paracetamol)Pain and fever. The safest pain reliever for almost everyone.Don't exceed the label dose: it damages the liver.
IbuprofenPain with inflammation: bumps, sprains.Stomach, kidney or heart problems, high blood pressure.
AntihistamineAllergies, stings, hives.Some cause drowsiness.
Oral rehydration saltsDiarrhea and vomiting: prevent dehydration.Mix with safe drinking water.
LoperamideDiarrhea in adults.Not with fever or blood in the stool.
Hydrocortisone creamItching, bites, irritation.Short-term use.

Choose tablets over capsules or effervescent sachets: they handle moisture and knocks better.

In most countries antibiotics need a prescription, and taking them on your own breeds resistance. Don't include them unless your doctor has prescribed them.

Personal items: what really matters

  • Prescription medication for at least one week, ideally two, with a copy of the prescription or medical report.
  • Epinephrine auto-injector, if someone needs one: it's the most important item in the whole kit.
  • Inhalers, glucose meter and strips, hearing aid batteries.
  • A sheet listing each person's allergies, conditions and medication.

What to leave out

  • Hydrogen peroxide and rubbing alcohol on open wounds: they damage healthy tissue and slow healing. To clean, use plenty of drinking water or saline.
  • Suture kits and scalpels without medical training.
  • Cheap pre-made kits: they're usually full of band-aids and light on what matters. Build your own.

Maintenance

Check expiry dates every six months, together with the kit review. Store it in a box that closes well, somewhere cool and out of children's reach, and make sure everyone knows where it is. Keep a smaller version in your go-bag and another in the car.
