What Should Actually Be in a First Aid Kit?

If you have ever bought a first aid kit, opened it, and thought:

Why are there 47 tiny Band-Aids in here?

You are not alone.

A lot of pre-made first aid kits technically contain a lot of things, but that doesn't necessarily mean they contain the things you are actually going to need.

And honestly, there isn't one perfect first aid kit.

The kit I want in my car is different from the one I want at home. The kit I bring hiking is different from the one we use at an event. A family with small children has different needs than someone living alone. Someone doing street outreach probably needs something completely different from someone stocking an office break room.

So instead of asking:

"What is supposed to be in a first aid kit?"

I think the better question is:

"What might happen here, and what would I want to have with me if it did?"

Start with the basics

There are some supplies that make sense in almost every general first aid kit.

Gloves

Get nitrile gloves.

They give you a barrier between you and blood, vomit, drainage from a wound, or other body fluids. I like having multiple pairs because sometimes you need more than one, another person is helping you, or something gets contaminated.

Also, please make sure they actually fit the people who may use them.

One pair of giant gloves shoved into the bottom of a kit does not count as preparedness.

Bandages

Yes, Band-Aids are useful.

No, you probably do not need 75 of the exact same size.

A mix of adhesive bandages works much better. Small ones are great for little cuts, but larger bandages are helpful for scraped knees, larger cuts, blisters, and wounds that are just slightly too inconveniently shaped for the standard little strip.

Gauze

This is one of the things I wish more basic kits had enough of.

Gauze pads can cover wounds, absorb blood, and help you apply pressure to bleeding.

I like having a couple different sizes because a tiny cut and a large abrasion are obviously not the same situation.

Roller gauze is also useful for keeping a dressing in place, especially somewhere like an arm, hand, leg, or foot where adhesive bandages are not always going to cooperate.

Medical tape

You will eventually need to secure something.

Gauze. A dressing. Padding. A bandage that refuses to stay where you put it.

Tape is not exciting, but neither is trying to MacGyver wound care with whatever sticky object happens to be nearby.

Something for cleaning

For most minor wounds, clean running water is incredibly useful.

If you are building a kit for somewhere that may not have easy access to clean water, that should factor into your supplies.

The goal is not to pour every antiseptic product known to humanity into a cut. It is to get dirt and debris out and protect the wound.

A cold pack

Instant cold packs are one of those things that seem unnecessary until somebody rolls an ankle, gets hit with something, bumps their head, or develops swelling and suddenly everyone is very excited that you packed one.

They are especially useful for kits that leave the house.

Scissors

Preferably scissors that can actually cut things.

Enough said.

Then think about bleeding

This is where I think a lot of tiny store-bought kits fall short.

A first aid kit should be able to handle more than a papercut.

At minimum, I want enough gauze or another absorbent dressing to apply firm direct pressure to a bleeding wound.

Depending on where the kit will be used and the level of training of the people using it, you may also want supplies specifically for major bleeding.

That can include things like trauma dressings or a commercial tourniquet.

The important part is not just owning the equipment. Know what it is, know when you would use it, and ideally practice before the day someone is actually bleeding in front of you.

Think about burns

For a general household kit, you do not need an entire burn unit in a zipper pouch.

You do want a plan.

Minor thermal burns should generally be cooled with cool running water, not ice. Depending on where your kit is going, nonstick dressings or other supplies for protecting a minor burn afterward can be useful.

If you are building a kit for a kitchen, campsite, workshop, festival, or anywhere else burns are more likely, this category deserves a little more attention.

Think about the people using the kit

This is the part that gets missed all the time.

First aid kits are not just about injuries.

They are for people.

Does anyone have severe allergies?

Would having an extra face mask be useful?

Does someone need communication supports?

Would someone benefit from earplugs or another sensory tool during an overwhelming situation?

Are there children around?

Do you regularly spend time with older adults?

Does anyone menstruate?

Are you somewhere where opioid overdose could happen?

Do people have medications or medical devices that should be considered when planning for emergencies?

Not all of those things belong inside every single first aid kit.

But they absolutely belong in the conversation about preparedness.

Where is the kit going?

This might be the most important question.

A home kit

Think everyday injuries and illnesses.

Cuts. Scrapes. Minor burns. Splinters. Sprains. Blisters. Nosebleeds. Fevers. Someone waking up at 2 a.m. feeling absolutely terrible.

A home kit can be larger because you are not carrying it around.

A car kit

Now we need to think differently.

You might be away from home. You may encounter a crash. You might get stranded. Weather matters, especially here in Minnesota.

You probably want supplies for wounds and bleeding, but emergency preparedness items may make sense too.

And remember that cars experience extreme temperatures. Check anything in your vehicle kit that can expire, degrade, freeze, melt, or otherwise become less useful after sitting in a Minnesota car for six months.

A hiking or adventure kit

Weight matters.

So does how far you are from help.

Blisters suddenly become a much bigger deal when you still have four miles to walk.

The terrain, weather, activity, number of people, and distance from EMS should all influence what you bring.

A sports kit

Think about the injuries associated with the activity.

Cuts and scrapes? Definitely.

Blisters? Probably.

Cold packs? Yep.

Wraps and dressings? Useful.

And depending on the sport and environment, you may need to think much more seriously about emergency equipment and emergency action planning beyond the first aid kit itself.

An event kit

This one can get big very quickly.

When we plan medical coverage for events, we are not preparing for one specific injury. We are thinking about the size of the crowd, weather, environment, accessibility, activities, expected demographics, substance use, distance from EMS, previous incidents, and what resources already exist onsite.

That is a very different situation from packing a pouch for your backpack.

Add the things that match your life

This is the fun part.

Maybe you are constantly getting blisters.

Put blister care in there.

Maybe your kid somehow manages to scrape a knee every time you leave the house.

Pack more wound supplies.

Maybe you go to concerts and festivals.

Naloxone might make sense.

Maybe your family spends the entire winter outside.

Cold-weather supplies matter.

Maybe somebody gets migraines and needs a quiet, low-sensory environment when they do not feel well.

Think about sensory support.

Maybe you travel constantly.

Your travel kit probably deserves more attention than the first aid kit collecting dust under your bathroom sink.

Preparedness works better when it is built around your actual life.

And please check your kit occasionally

A first aid kit is not a time capsule.

Things get used.

Packages rip.

Adhesive dries out.

Medications and certain supplies expire.

Gloves deteriorate.

Someone borrows the scissors and mysteriously they are never seen again.

The American Red Cross recommends checking kits regularly and replacing used or expired supplies.

You do not have to inventory your home first aid kit every Tuesday.

Just open it once in a while.

Especially before a trip, event, camping weekend, sports season, or anything else where you are more likely to need it.

The best first aid kit is the one that makes sense for you

There are absolutely standard recommendations for first aid supplies. The American Red Cross, for example, recommends basics including assorted adhesive bandages, gauze, tape, nonlatex gloves, a cold compress, breathing barrier, thermometer, triangular bandages, tweezers, and first aid instructions in a family kit.

Those lists are a great starting point.

But they are a starting point.

Your first aid kit should match the people who might use it, the environment it lives in, the activities happening around it, and the emergencies you are realistically preparing for.

That is also why we build EQUIPped Kits around different situations instead of trying to make one enormous kit that somehow works perfectly for everyone.

Sometimes you need wound care.

Sometimes you need a tiny kit that fits in your bag.

Sometimes you need a family kit.

Sometimes you need blister supplies, naloxone, menstrual products, sensory supports, burn care, or a full event setup.

The goal isn't to own the most first aid supplies.

The goal is to have the right things when you actually need them.
