What to Look for in a First Aid Kit: Contents Checklist and Buying Guide

A good first aid kit covers bleeding control, wound cleaning, bandaging, infection prevention, CPR barriers, minor burns, sprains, and basic medications — and the right contents change with home, car, travel, or workplace use.

Most store-bought kits look reassuring on the shelf, then turn out to be 40 adhesive bandages and almost nothing that stops serious bleeding. Knowing what to look for comes down to matching contents to where you’ll use it, then checking a short list of items cheap kits habitually skip.

The Core Categories Every Kit Needs

Every credible checklist covers nine jobs: bleeding control, wound cleaning, bandaging, infection prevention, CPR barrier protection, minor burn care, sprains and strains, basic medications, and a written guide. If a kit can’t handle all nine, it’s incomplete regardless of how many bandages it contains.

The American Red Cross family kit baseline for four people is the clearest benchmark for home use: 2 absorbent compress dressings (5 x 9 in), 25 adhesive bandages, cloth tape, 5 antibiotic ointment packets, 5 antiseptic wipes, 2 aspirin packets (81 mg), an emergency blanket, a breathing barrier with a one-way valve, an instant cold compress, 2 pairs of nonlatex gloves, hydrocortisone packets, gauze rolls and pads, a non-mercury oral thermometer, 2 triangular bandages, tweezers, and printed first aid instructions.

Mayo Clinic’s guidance adds an eye shield or pad, an aluminum finger splint, an irrigation syringe, sterile saline, eyewash solution, and a splint-friendly setup. A prescribed epinephrine auto-injector belongs only if a doctor has prescribed one — never add it on your own.

What to Look for Before You Buy

• Gloves and barriers. Nonlatex or nitrile gloves and a CPR breathing barrier are non-negotiable.
• Bleeding control beyond bandages. Look for gauze pads, roller bandages, and — for workplaces and higher-risk settings — a windlass tourniquet and hemostatic gauze.
• A real manual. A printed first aid guide matters when your hands are shaking and the Wi-Fi is down.
• Expiration dates. Ointments, wipes, aspirin, and hand sanitizer all expire.
• Refill supply. Many kits sell replacement packs; ones that don’t become stale fast.
• Setting match. A home kit, a car kit, an outdoor travel kit, and a child-care kit are four different builds.

Aspirin appears in many kits because it’s useful during a suspected heart attack, but it isn’t a casual painkiller here. Keep it labeled and know why it’s there.

Home, Workplace, and Travel: How Requirements Differ

Workplace kits in the US are held to a written standard, and home kits are not. OSHA’s appendix cites ANSI Z308.1 as the reference for minimum workplace contents, and the current version, ANSI/ISEA Z308.1-2021, splits kits into two classes: Class A is the smaller baseline, Class B requires larger quantities and broader coverage.

Class A calls for 16 adhesive bandages, 10 antibiotic applications, 10 antiseptic units, 1 breathing barrier, 1 burn dressing, 1 cold pack, 2 eye coverings, 1 first aid guide, 1 foil blanket, and 10 hand sanitizer units. Class B scales those up — 50 adhesive bandages, 25 antibiotic applications, 50 antiseptic units, 2 burn dressings, 2 cold packs, and 20 hand sanitizer units — with the same single breathing barrier and guide.

For homes and vehicles, the Red Cross family list and Mayo Clinic’s additions are the practical benchmark. For travel and outdoor use, add blister treatment, butterfly closures, oral glucose, and a waterproof container. If you’d rather start from a kit that already passed hands-on testing, our roundup of the best first aid kit options we tested breaks down what held up and what didn’t.

Match contents to the setting and any standard that applies rather than hunting for one universal list. Red Cross, Mayo Clinic, and ANSI lists overlap but were never designed to be identical.

Frequently Omitted Items Worth Adding

• Antiseptic wipes, liquid bandage, and antibacterial ointment for infection control
• Butterfly closures, blister treatment, and elastic wrap for closures and sprains
• Ibuprofen and an antihistamine alongside aspirin
• Safety pins, splinter tweezers, and finger or SAM splints
• Irrigation syringe, sterile saline, and eyewash solution
• A notepad, pen, and medical waste bag for documenting care and cleanup
• A waterproof, clearly labeled container that stays in one known spot

Keep the kit where everyone can find it, check it twice a year, and replace anything expired. A well-stocked kit you can locate beats a perfect one buried at the back of a closet.
