Camping first aid kit basics: build it by category, audit it every season
Safety note: this guide is general information about assembling a kit, not medical advice or first aid instruction. For anything beyond minor injuries, get professional medical help — and consider a hands-on first aid course, because a kit is only as useful as the person opening it.
Most first aid kit advice is a shopping list, and most first aid kits are bought the same way: everything at once, thrown in a pouch, and never thought about again until the pouch is opened at the worst possible moment — with two bandages left and a dried-out tube of something. Build the kit by category instead, in the order incidents actually demand things, and maintain it like the system it is.
The four categories, in buying order
| Category | Core contents | Why this order |
|---|---|---|
| 1. Wound care | Assorted adhesive bandages, gauze pads in more than one size, wound-closure (butterfly) strips, elastic wrap bandage, medical tape, sterile saline, antibiotic ointment or plain petroleum jelly, blister pads or moleskin | Cuts, scrapes and blisters are the overwhelming majority of campground incidents; this category is used on nearly every trip |
| 2. Tools and protection | Non-latex gloves, trauma shears or scissors, tweezers plus a tick-removal tool, thermometer, instant cold pack, emergency blanket, hand sanitiser | The tools make category 1 usable — cleaning hands, cutting tape and clothing, removing splinters and ticks |
| 3. Medications and personal | Pain and fever relief, antihistamine, oral rehydration salts or electrolytes, antacid and anti-diarrheal basics, bite and sting relief — plus personal prescriptions with a small surplus, and prescribed allergy medication where that applies to your group | Personal items are the ones no generic kit can stock for you, and the ones whose absence ends trips |
| 4. The rescue layer | Whistle or signalling device, thermal blankets, spare hat and gloves, emergency shelter or tarp, extra water and electrolyte supplies, headlamp with spare batteries, a written card with the campground's location and the nearest hospital | For the incident where the kit's job changes from treating to keeping someone stable and findable until help arrives |
The category contents above follow a current camping first-aid guide's organisation for the first three categories. The fourth is where Canadian guidance is specific: the Canadian Red Cross's list of additions for hiking, camping and remote environments names extra water and electrolyte supplies, blister care such as moleskin and padding, an emergency shelter or tarp, thermal blankets, a spare hat and gloves, a whistle or signalling device, a multi-tool or knife, and additional bandages and wound care. Its reasoning deserves quoting in spirit: in remote settings, help may be delayed, so being prepared is critical — and having the supplies is only the first step, because knowing how to use them is what counts.
One practice to update: what goes in a wound
If your first aid knowledge is older, one habit has been formally retired. Current guidance, summarised in a recent camping first-aid guide, is that major health bodies now advise against pouring hydrogen peroxide, iodine or rubbing alcohol into an open wound: they damage healthy tissue and can actually slow healing. The current practice is to rinse the wound with plenty of clean, drinkable water or sterile saline until debris is gone, remove anything stubborn with clean tweezers, apply a thin layer of antibiotic ointment or plain petroleum jelly, and cover it. Antiseptic wipes still earn their place — for cleaning your hands and the skin around the wound, just not inside it. Check any inherited kit for the brown peroxide bottle; it is the most common outdated item in Canadian camping kits, because older guidance recommended it.
Car camping vs carrying it: the size decision
One kit does not fit both trips, and pretending otherwise produces a kit that is too heavy to carry and too thin to matter. The decision framework is simple. If the kit lives in the car at a drive-up site, weight is nearly free: build all four categories fully, in a rigid, visible, waterproof container. If the kit goes in a pack, category 1 stays complete (it is light), category 2 sheds duplicates, category 3 is tailored to the actual people on the trip, and category 4 compresses to the whistle, one thermal blanket per person, and the written location card. What never gets cut at either size: gloves, saline for rinsing, closure strips, personal medications, and the means of signalling. Those five are the kit's irreducible core.
The seasonal audit (the procedure that keeps it a kit)
- Empty it completely onto a table at the start of the season. A kit audited in place is a kit whose bottom layer stays a mystery.
- Check every expiry date — medications, ointments, sterile items, adhesive that has lost its stick. Storage guidance is consistent: replace anything you use as soon as possible after the trip, and otherwise do a yearly check that nothing is damaged, opened, or out of date.
- Restock against the category table above, not against memory. Count wound care first; it depletes fastest and silently.
- Refresh the personal layer: prescriptions change, kids' doses change, allergy plans change. Last year's card is a historical document.
- Repack and store it correctly: somewhere safe, cool and dry, easy to reach in a hurry, and out of the reach of children — and tell every adult in the group where it lives.
What success looks like: every item in date, every category stocked, and any adult in your group able to find the kit in the dark and name what is in each category. If the kit's contents are a surprise to its owner, it is not finished, whatever it cost.
Common questions
Buy a pre-made kit or build one? A pre-made kit is a reasonable category 1 and 2 starting point — protection, cleaning and dressing basics are exactly what they contain — provided you add the personal layer and the rescue layer yourself and put the whole thing on the audit cycle. The failure mode is not pre-made versus built; it is bought and forgotten.
What about serious trauma gear? Some current guides carry items like a commercial tourniquet with an explicit condition attached: it is only as good as your training, and the guides themselves point readers to hands-on courses. That is the right gate. This basics article's position is the Red Cross's: training is the upgrade, and gear beyond your training is weight, not safety.
Where does the kit live at the campsite? Same rule as at home: cool, dry, reachable, out of children's reach — and in the same place every trip, so finding it is a habit rather than a search.
Pre-made kits, judged by category
If you buy a pre-made kit — a reasonable starting point — judge it against the category table rather than its advertised piece count. Piece counts inflate with the cheapest items in the box: a "200-piece kit" can be 140 adhesive bandages and very little else. The questions that expose a kit are categorical. Does wound care include gauze and closure strips, or only bandages? Are the gloves non-latex and actually present in more than one pair? Is there saline for rinsing, in line with current wound practice, or a peroxide bottle that dates the whole box? Is there anything at all in the rescue layer — a blanket, a whistle — or does the kit stop at the first two categories? A kit that answers those well is worth its price even with a modest piece count, because you are buying coverage across categories, not bandages by the hundred. Then add what no manufacturer can pack for you: the personal medications, the spare glasses, the allergy items, and the written location card for the trip you are actually taking.
