A first aid kit is the emergency supply you are most likely to actually use — and the one most people never upgrade beyond a drugstore box of bandages. The right kit depends on the injuries you are preparing for, from everyday cuts and burns to life-threatening bleeding.
Two tiers of preparedness
Every home and vehicle should carry a comprehensive first aid kit for the common injuries: cuts, burns, sprains, and blisters. Beyond that, a dedicated bleeding-control (trauma) kit addresses the injuries that ordinary bandages cannot — and those are the ones that cost lives in the minutes before help arrives.
Skills beat supplies
Even the best kit is only as good as the person using it. Pair your kit with a waterproof reference guide, and consider a Stop the Bleed or basic first aid course.
The bottom line
Buy a comprehensive kit for the household, add a compact trauma kit for the vehicle and workplace, and learn to use both before you need them.
