Where to keep first aid kits

The Red Cross advises keeping a first aid kit in your home and in your car, carrying one or knowing where to find one, and learning where the kits are at your workplace. Some kits are designed for activities such as hiking, camping or boating.

Ready.gov, the federal preparedness site, lists a first aid kit as part of a basic emergency supply kit and suggests preparing supplies for home, work and cars, since you do not know where you will be when an emergency happens. Make sure everyone in the household knows where the home kit is kept.

Buy a kit or build your own

The Red Cross says first aid kits come in many shapes and sizes, can be bought at a drug store, or can be made yourself. A ready-made kit is convenient; building your own lets you choose the sizes and brands you prefer.

Personal items to add

The Red Cross says to include personal items such as medications, emergency phone numbers, and other items your health care provider suggests. Ready.gov adds that about half of all Americans take a prescription medicine every day, and that an emergency can make refills hard to get, so keep your prescriptions, over-the-counter medicines and vitamins organized and protected.

Ready.gov's list of extra supplies also includes non-prescription medicines such as pain relievers, anti-diarrhea medicine, antacids and laxatives, as well as prescription eyeglasses and contact lens solution.

Check and restock your kit

For wound cleaning, see what the evidence says in our hydrogen peroxide guide and rubbing alcohol guide. For itchy bites and rashes, see our hydrocortisone cream guide.

Know when to call for help

A kit is for minor injuries and for helping until professional care arrives. The Red Cross includes emergency first aid instructions in its checklist; read them before you need them, and consider a first aid and CPR class. Call emergency services right away for severe bleeding, trouble breathing, chest pain, a serious burn, a head injury with confusion, or any emergency where you are unsure what to do.
