First Aid Supplies & Training
In an emergency, help can be minutes or hours away — and the gap between "minor injury" and "real trouble" is often whoever is standing there with a kit and the training to use it. This guide covers how to build a layered first aid setup, which supplies actually matter, the medications to stock, and the training that turns gear into outcomes.
Important
This is general preparedness information, not medical advice. Get hands-on training from a qualified instructor, and in a real emergency call your local emergency number when you can. See our full disclaimer.
Key takeaways
- Build first aid in layers: everyday kit → trauma kit → medications.
- The leading preventable cause of death from injury is bleeding — own a tourniquet and know how to use it.
- Training beats gear. Take Stop the Bleed, CPR, and a basic first aid class.
- Keep kits at home, in each vehicle, and in your bug-out bag, and rotate meds first-in, first-out.
Build it in layers
The fastest way to get overwhelmed is to shop for "a first aid kit" as a single purchase. Instead, think in three layers, each handling a different level of severity:
- Everyday kit ("boo-boo kit"): cuts, scrapes, blisters, burns, splinters, and sprains — the 95% of injuries you'll actually treat.
- Trauma kit (IFAK): life-threatening bleeding and serious wounds — the rare event that you can't afford to be unequipped for.
- Medications: over-the-counter relief plus a buffer of the prescriptions your household depends on.
Cover the everyday kit first because you'll use it constantly, then add the trauma layer, then shore up medications. A solid pre-built trauma first aid kit (IFAK) is a good base to upgrade from.
The everyday kit
These are the supplies you'll reach for most. Buy generously — quantities run out faster than people expect:
- Wound care: assorted adhesive bandages, gauze pads, medical tape, butterfly closures, antibiotic ointment.
- Cleaning: antiseptic wipes, saline for irrigation, tweezers for splinters and ticks.
- Burns & blisters: burn gel or dressings, moleskin, blister bandages.
- Sprains & supports: elastic (ACE) wrap, instant cold pack, triangular bandage/sling.
- Protection: nitrile gloves (several pairs), a CPR face shield, trauma shears.
The trauma kit (IFAK)
Severe bleeding can become fatal in minutes — long before an ambulance arrives. A small individual first aid kit (IFAK) built around bleeding control is the highest-impact upgrade most households are missing:
- A commercial tourniquet (a real CAT/SOF-T — not an improvised one); two is better than one.
- An Israeli pressure bandage for wrapping and applying pressure.
- Hemostatic gauze (e.g. QuikClot) for packing deep wounds.
- Chest seals, more nitrile gloves, and a permanent marker (to note tourniquet time).
Gear without training is a liability
A tourniquet applied wrong can fail when it matters most. Don't buy trauma supplies and stop there — take the Stop the Bleed course so your hands know what to do under stress.

Medications & prescriptions
Stock a basic medicine cabinet you can lean on when stores and pharmacies are closed:
- Pain/fever: ibuprofen, acetaminophen, aspirin.
- Stomach & allergy: anti-diarrheal, antacids, antihistamines (diphenhydramine), hydrocortisone cream.
- Cold & cough: decongestant, cough suppressant, electrolyte/rehydration packets.
- Topicals: antibiotic ointment, antifungal cream, anti-itch.
Most important: keep a 30–90 day buffer of any prescription your household relies on. Ask your provider about an emergency supply, mail-order 90-day fills, or filling refills a few days early to build a rolling cushion. Note medications that need refrigeration and plan for them in your power backup.
Training: the part that actually saves lives
Supplies are the easy half. Skills are what let you act in the first chaotic minutes. Prioritize these, in order:
- Stop the Bleed — tourniquet use and wound packing; a short, inexpensive course.
- CPR/AED — hands-only CPR and using a public defibrillator (Red Cross or AHA).
- Basic First Aid — burns, fractures, shock, and when to escalate.
- Wilderness First Aid (WFA) — if you hike, camp, or live far from fast EMS response.
Keep a printed first aid manual with your kit — a reference works when your phone and the internet don't, and helps a less-trained family member follow along.
Where to keep your kits
Following "two is one, and one is none," distribute kits so one is always within reach:
- Home: a full everyday kit plus the trauma layer, somewhere everyone knows.
- Each vehicle: a compact kit with a tourniquet — car crashes are a likely trauma scenario.
- Bug-out bag: a lightweight kit so your 72-hour bag can stand alone.
- Everyday carry: at minimum, a tourniquet you can actually reach.
Storage & rotation
Treat medical supplies like food storage: rotate first-in, first-out, write the date on each item, and audit every kit twice a year (tie it to daylight-saving clock changes). Replace anything expired or degraded, restock what you used, and keep kits cool and dry — heat in a hot car shortens the life of medications and adhesives.
