What a Real Bleeding Kit Needs
The green box in the cupboard is built for paper cuts. Here is what a kit for serious bleeding contains, and why each item earns its place.
Jarrett Chisholm, ACP · August 22, 2026
Open the first aid kit in most homes, cars and small offices and you will find plasters, a triangular bandage, antiseptic wipes, a pair of scissors that will not cut anything, and a foil blanket. That kit was designed for minor injury, and for minor injury it is fine. It contains almost nothing that helps with bleeding that is going to kill someone in ten minutes.

bleeding-control-kit-contents-laid-out-on-bench.jpg
Overhead flat lay on a plain workbench or grey mat. Items spaced evenly and all clearly identifiable: two pairs of nitrile gloves, one commercial windlass tourniquet, one roll of packing gauze in its sealed pouch, one pressure dressing, orange-handled trauma shears, a roll of tape, a black permanent marker. Even diffuse light, no shadows across labels, generous negative space, no branding of a specific retailer.

The gap is not about quality. It is about what the kit was assembled to solve. A bleeding emergency needs a small number of specific items, each of which does something the ordinary contents cannot, and none of which you can improvise well under pressure.
Buy them once, keep them where you can reach them in seconds, and learn how each one works before you need it. A kit you have never opened is a box of unfamiliar packaging at the worst possible moment, and packaging is remarkably hard to open with wet gloves on.
Everything below is standard, widely available, and not expensive relative to what it does. The main cost is deciding to bother before something happens rather than afterwards, which is the part almost everyone gets wrong. the kit items we stock for exactly this.
The items that change the outcome
Gloves, and more than one pair. They protect you, and protecting yourself is not optional on a scene where you will have both hands in someone's blood for twenty minutes. Nitrile, in a size that actually fits the largest person likely to use the kit, because gloves that will not go on get skipped.
A manufactured windlass tourniquet. Not a belt, not a strap without a windlass, not a novelty one from a discount site. The mechanism has to generate and hold enough force to close an artery inside a thick thigh, and the design has to survive being used by frightened hands. Buy from a supplier who can tell you exactly what you are getting, and buy two, because a limb sometimes needs a second one and because the day you use it you will want a spare.
Haemostatic or plain gauze on a roll, for packing. This is the item people leave out, and it is the one that covers everything a tourniquet cannot: the groin, the armpit, the neck, deep wounds in the torso. Packing means feeding gauze firmly down into the wound track until the cavity is full, then holding pressure on top of it. It uses far more gauze than anyone expects, which is why two small square dressings will not do the job.

An instructor stands to the side, watching the hands rather than the camera. Classroom lighting, sharp focus on the gauze entering the wound, simulated blood present but restrained.

The supporting kit
A pressure dressing and a pair of trauma shears. The dressing is a bandage built to hold firm pressure over a pad without someone kneeling on it, which frees a pair of hands in a situation that never has enough of them. The shears exist because you cannot treat a wound you cannot see, and getting through denim, coveralls or a boot with household scissors is a slow, ugly failure.
Add a permanent marker and a roll of tape. Both weigh nothing and both matter at handover: the time a tourniquet went on, what you found, what you did. Ambulance and hospital teams make different decisions depending on that information, and memory under adrenaline is not reliable.
Skip the things that look useful and are not. Antiseptic wipes do nothing for major bleeding. A foil blanket is worth keeping for shock and cold, but it is not bleeding control. And a kit sold as a trauma kit that turns out to hold forty plasters and one small dressing is an ordinary first aid kit with a different sticker on the box.
Where it lives, and who can open it
Reachability beats completeness. A perfect kit in a locked cabinet on another floor loses to a basic one in the vehicle you are standing beside. Serious bleeding gives you minutes, and most of those minutes are spent with your hands already occupied, so the kit has to be somewhere a bystander can be sent to fetch it and actually find it. On a vessel, a remote worksite or a truck a long way from town, that calculation gets harsher still, because the kit you have with you is the only kit there is. the version written for people working on the water.
More than one person needs to know it exists. Tell the people you live and work with where it is, what is in it, and how it opens. In a workplace that means it appears in the induction rather than in a binder, and it means the night shift knows as much as the day shift does. ask us what your site actually needs.
Check it on a schedule. Gauze packaging degrades, gloves perish, and tourniquets live in vehicles that reach fifty degrees in a Calgary summer and well below freezing in January. Pick a date, put it in a calendar, and when something expires, open it and practise with it rather than dropping it in the bin sealed.
Quick answers
- What do you need in a kit for serious bleeding?
- At minimum: nitrile gloves, a manufactured windlass tourniquet, a roll of gauze for packing wounds, a pressure dressing, trauma shears, tape and a permanent marker. Each of those does something the contents of an ordinary first aid kit cannot.
- Is a belt a good substitute for a tourniquet?
- A belt is not a reliable tourniquet, because it cannot be tightened enough and has no windlass to hold the tension. Improvised devices fail often, so keep a manufactured one if you have any reason to expect serious bleeding.
- How often should a bleeding control kit be checked?
- Put it on a fixed schedule, at least once a year, and check it again after any use. Gauze packaging degrades, gloves perish, and tourniquets stored in vehicles suffer badly from heat and cold, so expiry dates matter more here than they do on plasters.
