What Is an IFAK? What Goes Inside, Who Decides, and What to Check Before You Buy

IFAK stands for Individual First Aid Kit. Some units call it an Improved First Aid Kit. Either way the meaning is narrow and worth holding onto: it is one person’s kit, carried on that person, for treating that person.

That last part is the whole design. An IFAK is not a team’s medical bag. It is not a vehicle kit. It carries what one operator, officer or worker needs in the first minutes of a serious bleed, before anyone with more training and more equipment arrives.

Most pages about IFAKs give you a contents list and stop there. A list is easy to write and impossible to check. This page does the other things. It names the body that decides which devices belong in one. It shows where the kit rides and what that costs you in measured terms. It exposes the scenario the standard kit was designed around. Then it gives you the questions to send a supplier before you order.

Quick Answers

What an IFAK Actually Is – and What It Is Not

Three things separate an IFAK from a general first-aid kit.

It treats bleeding and airway, not scrapes. Plasters, antiseptic wipes and burn gel belong in a workplace first-aid box. An IFAK follows the order the TCCC guidelines themselves use for a casualty: massive hemorrhage first, then airway, then respiration and breathing. The contents follow that sequence, not an inventory count.

It is carried by the person it treats. That drives the size, the mounting and the layout. A kit that lives in a vehicle or on a wall gets to be bigger and better stocked. A kit on a belt has to be small enough that it is still there when it is needed.

It assumes someone else is coming. This is the part almost nobody writes down, and it matters more than any item on the list. We come back to it in detail below, because it is the assumption that decides whether the standard kit is the right purchase at all.

So when you see two listings, both called IFAK, both showing a pouch and a handful of items, the label has told you nothing. What separates them is which devices are inside, whose recommendation those devices sit on, where they ride, and what situation the whole thing was designed for.

Why the priority order is what it is, mechanically: a casualty bleeding from a limb artery can lose enough circulating volume to become unrecoverable in a handful of minutes, which is faster than an obstructed airway kills and far faster than an untreated chest injury. So the sequence is not a preference about what matters most in general. It is an ordering by how quickly each thing runs out of time. That is also why the kit is small: anything that cannot be reached and used inside those few minutes is, for this purpose, not in the kit at all.

What the category cannot do sets the other edge. An IFAK does not treat internal bleeding, does not replace lost volume, and does not stabilize a fracture in any lasting way. Choose the specification against that limit rather than against a wish list.

One boundary worth setting now. An IFAK is a bridge, not a treatment plan. Its job is to keep someone alive across the gap between injury and definitive care. Nothing in it fixes the injury. If your planning assumes the kit resolves the emergency rather than buying time, the specification will be wrong no matter which brand you choose.

What’s Actually Inside One

The contents are stable across serious kits because the priority order is stable. Read any listing against these four groups rather than against a competitor’s list.

Two notes on how to read that table, and one thing the table deliberately leaves out: quantities. Every serious kit carries these four groups. What separates a kit that works on your worst day from one that does not is how many of each, and that number comes from the scenario rather than from the category.

Quantity is the real variable, not the item list. Almost every disagreement between two kits is about how many tourniquets, how much gauze, and whether there is a second of anything. The item types rarely differ. The quantities differ a lot, and quantity is what the scenario decides.

The enabling items are where cheap kits cut. Shears that will not cut a boot, gloves that tear on the way out of the pouch, no marker for the tourniquet time. None of these appear in a headline specification, and all of them decide whether the expensive items get used correctly.

Take one concrete instruction from the table before moving on: Pick the kit whose quantities match your casualty count, and treat the enabling items as a specification line rather than packaging. A supplier who cannot state shear capability or glove size range has not thought about the part that decides whether the rest gets used.

That ordering is not a house style. The TCCC guidelines work through a casualty in numbered steps, with massive hemorrhage at step 3 of the tactical field care plan, airway next, then respiration and breathing at step 5. Check any candidate kit against that sequence rather than against a competitor’s list. A pouch with three tourniquets and no chest seal is a visible gap, not a matter of taste.

Who Should Carry One

The answer is narrower than most listings imply, and getting it wrong is expensive in both directions.

One kit, one person, self-aid and buddy-aid. The IFAK is issued to an individual and is meant to be used on that individual, most often by that individual or by whoever reaches them first. That is why it is small, why it lives on the body, and why it holds one casualty’s worth of consumables.

It is not the medic’s kit. A medic carries a different tier with different quantities and items that assume trained hands. Buying IFAKs for a medic is under-equipping them. Buying medic bags for everyone is spending money on capability nobody is trained to use.

It is not the vehicle kit. A vehicle or facility kit can be larger, heavier and better stocked because nobody carries it on their body. If your team spends most of its time within reach of a vehicle, the sensible design is a small kit on each person plus a larger one in the vehicle, not a compromise kit that is too big to carry and too small to matter.

The practical consequence for a buyer is that a mixed population needs a mixed order. A patrol officer, a line supervisor in a plant, and a designated first responder do not need the same kit even if all three sit on the same purchase order. Standardizing on one specification for everyone is the most common procurement mistake in this category, and it usually shows up as kits that are never worn because they are too bulky for the role.

The mechanism behind the role split is time and hands. Self-aid and buddy-aid happen in the first minutes, by whoever is present, usually one person working with one free hand under stress. Everything above that tier assumes a second responder who arrived on purpose, with training and with both hands available. Kit design follows that difference: the individual kit is built for one-handed access to a small number of items, and a medic bag is built for breadth because someone will be kneeling beside it with time to look.

The military version of this split is documented rather than assumed. The USSOCOM program that produced the modern individual kit built three tiers deliberately, starting with the individual kit in 2006 and adding the medic bag and evacuation set above it. Name the tier for each role on the purchase order before you compare any supplier’s specification, because a mixed population buying one specification always over-equips some roles and under-equips others.

Decide the roles first, then count how many of each tier you need. That count is what you take into the next two sections, because it interacts directly with what the guidelines recommend and with the scenario the kit assumes.

What the Authority Actually Recommends

Vendors publish contents lists. None of the six pages ranking for this term when we checked cited a source for theirs. That is the gap this section closes.

There is a source. For trauma care in tactical and prehospital settings the reference point is the Committee on Tactical Combat Casualty Care, usually written CoTCCC, whose guidelines are published openly. They do not describe a pouch. They name device classes, say which are preferred and which are alternates, and attach the rules for using each.

Three things follow from that, and they are the three most useful facts on this page for anyone about to compare listings. The guidelines name a preferred item rather than a category. They attach usage rules to the items, so the rule travels with the product. And they say what to do when something fails, which is the part a contents list can never tell you. Take them in order.

The hemostatic dressing decision, as the guidelines state it

Take the item buyers get wrong most often. The current TCCC guidelines say that for compressible external hemorrhage not amenable to limb tourniquet use, or as an adjunct to tourniquet removal, Combat Gauze is the CoTCCC hemostatic dressing of choice. The listed alternative hemostatic adjuncts are Celox Gauze, ChitoGauze, and XStat, with XStat described as best for deep, narrow-tract junctional wounds. The iTClamp appears alongside them and may be used alone or together with a hemostatic dressing or XStat.

That single passage gives a buyer four things a contents list cannot.

A preferred item and a named alternate set. Not “hemostatic gauze” as a category, but one preferred product and three named alternates. A kit whose hemostatic dressing appears nowhere in that set is not automatically bad. It is unverified, which is a different thing, and it is the thing you are actually deciding about.

A geometry restriction. XStat is not a general-purpose substitute. The guidelines reserve it for deep, narrow-tract junctional wounds. A kit that carries XStat as its only hemostatic option has been specified for a wound shape most buyers will never meet.

An application rule that comes attached to the product. Hemostatic dressings should be applied with at least three minutes of direct pressure, and that requirement is optional only for XStat. This matters at purchase time because it tells you the item assumes a trained pair of hands is available for three uninterrupted minutes. If your scenario cannot supply that, the item will underperform regardless of brand.

A failure procedure. The guidelines state that each dressing works differently, so if one fails to control bleeding it may be removed and a fresh dressing of the same or a different type applied. XStat is the exception: it is not to be removed in the field, though additional XStat, other hemostatic adjuncts or trauma dressings may be applied over it. Read as a purchasing instruction, that sentence says a kit stocked with exactly one hemostatic dressing has no answer for its own first failure.

The tourniquet is a class, not a category

The same precision applies further up the list. The guidelines do not say “a tourniquet”. They say a CoTCCC-recommended limb tourniquet, applied over the uniform clearly proximal to the bleeding site, and placed high and tight when the bleeding site is not readily apparent. A windlass device that resembles a recommended one is not thereby in the class.

Junctional bleeding gets its own instruction. Where the bleeding site is amenable to a junctional tourniquet, the guidelines say to apply one immediately and not to delay once it is ready for use. Hemostatic dressings with direct pressure are what you use if a junctional tourniquet is unavailable, or while one is being readied. For a buyer that is a sequencing fact, not a preference: a kit built for junctional risk without a junctional option is relying on its second-best answer by design.

What a recommendation is, mechanically

It helps to know what sits behind the word “recommended”, because that is what you are buying when you buy inside a class. A committee reviews the published evidence for a device type, weighs it against battlefield use, and issues a preference: one item of choice, a named set of alternates, and the conditions attached to each. The output is a consensus position that gets revised as evidence changes. It is not a test certificate for one manufacturer’s batch, and it is not a procurement contract.

Compared with the other two signals a buyer meets, the difference is worth holding straight:

That table is the whole reason to ask the class question rather than the brand question. Two of the three columns are checkable by you, from public documents, without the seller’s help.

Which class binds depends on what you are equipping for. A team facing limb injuries in an industrial setting is served by the limb tourniquet and a hemostatic gauze. A team with junctional exposure needs the junctional option in the specification, because the guidelines put it ahead of the dressing when the site allows it. And a kit for people trained only to self-aid should avoid the item with the irreversible placement rule, because the failure mode of XStat in untrained hands is a decision nobody can undo.

How to turn this into a purchase test

Take any vendor’s kit and ask one question of each item: which recommended class does this belong to, and can the seller name it?

• The seller names the class, and you can check it yourself against a public document.
• The seller names a product but not a class, and you have a research task rather than an answer.
• The seller answers with an adjective, and you have learned something about the seller.

Then ask the second question: does the kit carry the rules along with the items? A supplier who knows their hemostatic dressing needs three minutes of pressure, and that one of the alternates cannot be removed once placed, is selling a system. A supplier who has only ever thought about the item is selling a pouch.

A worked check. Suppose a listing reads: tourniquet, hemostatic gauze, chest seal, gloves, shears. Run the class question across it. The tourniquet has no class named, so ask which recommended limb tourniquet it is; if the answer is a model name you can match against the guidelines, that line resolves. The hemostatic gauze names no active agent, so ask whether it is the item of choice or one of the named alternates; “kaolin gauze” is an answer you can check, “military grade” is not. The chest seal and the enabling items sit outside the hemostatic classes, so they are judged on specification rather than on listing. Two questions, sent in one email, and a listing that told you nothing becomes a listing you can rank against another.

One boundary before you use any of this

The recommended list is not a performance ranking. Being on it means the device survived a formal evidence review by the committee whose recommendations drive military and much civilian trauma practice. It does not mean the product clots fastest, and a device cleared by a regulator but absent from the list is not thereby unsafe. What the list tells you is how much independent scrutiny stands behind a device.

That is a narrower claim than most marketing makes, and it is more useful, because it is checkable. A contents list cannot be checked. Class membership can.

Where It Rides: Mounting, Access and What That Costs You

Carry position looks like a preference. It is measurable, and the measurement is unkind to the most common setup.

Between February and May 2010, a US Marine battalion reported a 10% breakage rate for tourniquets, ten failures out of ninety-two. One theory was that the Afghan environment had weakened them. A study published in Military Medicine in 2013 tested it directly, comparing tourniquets carried through that environment against unexposed controls, in three arms: worn on the exterior of a plate carrier, carried inside the IFAK in the manufacturer’s plastic wrapping, and carried inside the IFAK with the wrapping removed.

The results split cleanly along one variable, and it was not the wrapping.

Read that table as a buyer and three things follow.

Carry position is a performance variable, not a packaging detail. The same tourniquet, from the same supply, performed at 57% or at control level depending only on where it rode. That is a larger difference than most buyers will find between two brands.

Enclosure did the work, not the plastic. Tourniquets inside the kit performed the same whether the manufacturer’s wrapping was left on or taken off. What protected them was being inside a closed pouch, out of sun, dust and abrasion. So the specification that matters is a closed compartment, not a particular wrapper.

The failure mode is mechanical, and it is silent. No control or IFAK-stored tourniquet broke. Forty-six of the externally carried ones did. Breakage is discovered at the moment of use, which is the worst possible moment to discover it. The study also found no significant difference between the four groups in the number of turns needed to stop the distal pulse, which is the point: the surviving devices worked normally, and the damaged ones simply failed.

Why exposure degrades a tourniquet

The mechanism is ordinary materials science rather than anything exotic. A limb tourniquet is webbing, a plastic buckle or clip, and a windlass rod. Sunlight degrades the polymer in both the strap and the buckle over months of exposure. Grit works into the weave and abrades it every time the wearer moves. Heat cycles soften and re-set plastic components. None of that is visible from outside, which is why the failure shows up as a snap under load rather than as a worn appearance during an inspection.

That mechanism explains the shape of the result. Efficacy fell because a partly degraded strap stretches under tension instead of holding pressure, so the distal pulse does not stop. Breakage is the same process one step further along. The enclosure protects against all three inputs at once, which is why wrapped and unwrapped kit-stored tourniquets performed the same: the pouch, not the plastic, was doing the work.

Where this varies. The exposure in that study was one climate over one deployment. A kit carried inside a temperate-climate patrol vehicle sees a fraction of that ultraviolet and abrasion load, and a kit worn daily in desert sun sees more. Compared with the storage conditions most civilian buyers actually have, the study is a worst case rather than a typical one. What transfers is the ranking, not the percentage: enclosed beats exposed, and the gap widens with exposure.

What the study does not tell you. It tested one device type in one environment, and it did not measure how long the degradation takes to appear. So it supports a rotation policy for externally carried items, and it does not tell you whether that interval should be six months or two years. That number has to come from your own conditions and from the manufacturer’s guidance.

There is a real tradeoff on the other side, and this page is not going to pretend otherwise. A tourniquet strapped to the outside of a plate carrier is faster to reach with either hand. That is why people mount them there. The honest conclusion is not “never carry externally”. It is that external carry has a measured cost that has to be paid for deliberately, usually by rotating that tourniquet out of service on a schedule and keeping a protected one inside the kit as the one you actually trust.

For a purchase specification this turns into two concrete lines. State where each item is expected to ride. And where anything rides externally, state its replacement interval, because you are now buying a consumable rather than a durable.

The Assumption Inside the Kit: One Casualty, a Short Evacuation

Here is the part the contents lists leave out, and it is the reason two kits with identical contents can be right and wrong for the same buyer.

The modern IFAK was designed to stabilize one casualty for a short time, until evacuation. That assumption is baked into how much of everything it holds. One tourniquet, or two. One hemostatic dressing. Enough to bridge a gap that somebody else is expected to close.

That sentence sounds unremarkable until you price it. Everything the kit holds was sized against it, so if your situation breaks the assumption, every quantity in the specification is wrong at once, and none of it shows up as a defect. The next three sections take that apart: why the failure appears as depletion rather than breakage, how to test your own situation against the assumption in two numbers, and what to do when the answer is that this category is the wrong purchase.

What happens when the assumption fails

A 2026 paper in the Journal of Special Operations Medicine puts it under load. Beerbaum and Henderson describe the single-casualty, short-evacuation premise as increasingly invalid in large-scale combat operations, drawing on a firsthand account from a trench engagement in Ukraine and structured interviews with a combat-experienced soldier. Sustained artillery, mortar and drone-delivered munitions produce multiple simultaneous casualties with complex polytrauma and prolonged evacuation delays. Under those conditions standard IFAK contents are depleted repeatedly.

The kit does not fail because the items are wrong. It fails because the arithmetic behind it assumed a different day.

That framing is not new to the people who designed these kits. The USSOCOM CASEVAC Set program, described in the same journal in 2012, was deliberately built in three steps: an improved IFAK first, then a medic bag, then the CASEVAC set itself. The stated intent was to standardize the medical loadout across special operations components. The individual kit was never meant to be the whole answer. It was designed as the first of three echelons.

Which means a buyer who purchases only the first echelon has bought one third of a system, and needs to know it.

Why depletion, not breakage, is the failure mode

The mechanism is arithmetic rather than equipment. A kit holding one hemostatic dressing answers exactly one packing job. The guidelines themselves assume that job can fail and be repeated with a fresh dressing, so a single-dressing kit is already one short of the procedure it was built around. Scale that to two casualties and the shortfall doubles before anyone has made a mistake. Stretch the evacuation and it doubles again, because a wound that would have been handed over at twenty minutes is now held for two hours by the same consumables.

Compared with the failure modes buyers usually plan for, this one is invisible at purchase time. A broken tourniquet gets discovered in an inspection. A kit that is correctly stocked for the wrong scenario passes every inspection it will ever face, and then runs out.

A worked example. Take a six-person team, one kit each, twenty-minute planned evacuation. That is six casualties’ worth of consumables for a plan that expects one. Now change one variable: a single incident injures two people and the evacuation slips to ninety minutes. The two casualties consume their own kits, then the kits of whoever is treating them. The team is now four kits down and has spent nothing on the third and fourth casualty it can no longer treat. How far the shortfall runs varies with two conditions and nothing else: how many casualties arrive at once, and how long they are held Nothing was defective. The arithmetic was set for a different day.

The misreading to avoid. Depletion is easy to read as a quality problem, and suppliers are happy to sell a fix for it. Do not confuse a kit that ran out with a kit that failed. The first is a quantity decision you made at purchase; the second is a product defect. Buying a more expensive kit corrects only the second.

The Two-Number Test

Before comparing brands, run what we will call the Two-Number Test. It is not a capability model and not a kit specification. It is two numbers that decide quantity before any brand comparison starts.

How many casualties do you plan for? One kit per person covers one casualty per person, and only if that person is not the casualty. If your realistic bad day involves two or three people hurt at once, or one person hurt badly enough to need a second hemostatic dressing after the first fails, the constraint is quantity and resupply, not which pouch you bought.

How long until definitive care? A twenty-minute transport and a three-hour one are different specifications. Longer holds mean more consumables per casualty. They also change what “complete” means, because a kit sized for twenty minutes has no answer for hour two.

One casualty and a short clock, and the standard kit is the right shape; move on to which tier you need. Two casualties or a long clock, and no brand solves it. Buy quantity, plan resupply, and consider whether a second kit or a team bag belongs in the requirement. The Two-Number Test does not tell you which kit is better. It tells you whether the question you are asking is the right one.

Where this page disqualifies its own category

If your expected scenario is multiple simultaneous casualties or a prolonged evacuation, a single IFAK per person is the wrong purchase shape regardless of brand. Adding features to the individual kit will not close that gap, and neither will paying more for it. What closes it is quantity, a resupply plan, and an echelon above the individual kit.

That is an uncomfortable thing for a supplier to write, and it is the most useful sentence on this page. A vendor who cannot tell you when their product category is the wrong answer has not given you enough to decide with.

IFAK, AFAK, MFAK: Which Tier Applies to You

The tier names come up constantly in listings and they are not standardized across vendors, which is why buyers default to price.

The short orientation: an IFAK is the individual kit described above. An AFAK is usually positioned as an augmented or advanced kit, carrying more than one person’s worth of consumables. An MFAK is generally a medic’s kit, assuming trained hands and a wider skill set. The boundaries move between sellers, so treat the letters as a rough scale rather than a specification.

Compared with an IFAK, an AFAK generally carries more of the same consumables rather than different ones, while an MFAK assumes a trained operator rather than a bigger pouch. That distinction is the useful one: the first is a quantity decision, the second is a capability decision, and they have different budgets attached.

One anchor point does exist. The military lineage of the individual kit is documented: the USSOCOM program fielded an improved IFAK in 2006 as the first of three tiers. Everything above it in that program was defined by capability and by who carries it, not by an acronym, which is the pattern worth copying.

The rule is not the acronym. Pick the tier from two things: the role of the person carrying it, and the injury pattern you expect them to meet before help arrives. A vehicle-based patrol officer and a line medic in a dispersed unit need different kits even if both listings say IFAK.

The reason the naming drifts is worth knowing, because it tells you what to trust. There is no standards body assigning these acronyms. IFAK has a formal origin in military supply, which is why its meaning is comparatively stable; AFAK and MFAK grew out of vendor positioning, so each seller defines the boundary where it suits their product line. Choose the tier from the quantities in the specification rather than from the letters on the listing, and ask the supplier to state how many casualties the kit is intended to cover.

We will publish a full tier comparison separately. For now the practical test is quantity against your expected casualty count, which is the same test the previous section applied. And if the person carrying it is not trained past self-aid and buddy-aid, more items in the pouch will not help. Which brings us to the part buyers skip.

Training: The Kit Is a Skill, Not a Purchase

Every item discussed so far has a technique attached, and the technique is what decides the outcome.

The three-minute hold is the step people skip. The guidelines are explicit that hemostatic dressings should be applied with at least three minutes of direct pressure. Three minutes is longer than it sounds under stress, and there is no shortcut. An untrained responder who packs correctly and holds for forty seconds has spent the dressing and gained nothing.

Packing to the source is not the same as covering the wound. The agent works where it contacts the bleeding vessel. A hemostatic dressing laid over the top of a deep wound, or packed on top of pooled blood, is an expensive bandage. This is the most common misuse of the most expensive item in the kit.

One item cannot be undone. XStat is not to be removed in the field. Additional XStat, other hemostatic adjuncts or trauma dressings may go on top of it, but the decision to place it is final until the casualty reaches definitive care. A carrier who does not know that will try to remove it when it appears not to be working.

Sequencing beats improvisation. Where a junctional tourniquet is appropriate, the guidelines say apply it immediately and do not delay once it is ready. Hemostatic dressings with direct pressure are the answer while the junctional tourniquet is being readied, or when none is available. Knowing that order is training, not equipment.

The evidence for that sits in the guidelines themselves rather than in a training brochure. Three of the four rules above are stated as procedural requirements attached to the device: the minimum of 3 minutes of direct pressure, the instruction that a failed dressing may be removed and replaced, and the exception that XStat is not to be removed in the field. Those are not tips. They are the conditions under which the recommended item was reviewed, which means a carrier who does not follow them is not using the device the committee assessed.

Ask the supplier what training they include or recommend, and put the answer on the purchase order beside the product. A supplier who ships a kit with no reference to how its contents are used has quietly transferred the hardest part of the specification to you.

For a purchase decision the conclusion is blunt: training is a line item, not an afterthought. A kit issued to someone who has never used a tourniquet under time pressure is a compliance artifact. If the budget stretches to only one of the two, a cheaper kit with trained hands outperforms an expensive kit without them, and the guidelines’ own application rules are why.

Build It or Buy It Assembled

Both routes are legitimate. They are priced differently, and they are usually compared as if they were the same purchase.

Assembling your own gives you exact control over which recommended classes go in, lets you standardize on tourniquets your people already train with, and makes substitution easy when one component becomes unavailable. The costs are real and land later. You own the rotation schedule for every consumable with its own expiry. You assemble and inspect each kit. And you carry the documentation burden yourself when somebody asks what is inside and whether it is compliant.

Buying assembled moves that burden to the supplier. You get one line item, one expiry to track if the supplier dates the kit as a unit, and one place to send the verification questions in the next section. The cost is less control over individual components, plus a markup for the assembly.

The honest version of the price comparison is that building your own is not automatically cheaper. At low volume you buy components at single-unit prices while an assembler buys them by the carton. The saving appears at volume, and even then part of it is offset by the labor and the rotation tracking you have taken on. What building reliably buys you is control, not cost.

The cost mechanism is worth stating plainly, because it is where the intuition fails. Component prices fall in steps tied to carton and pallet quantities. An assembler buys across those steps for every kit they build; a buyer assembling twenty kits buys at the single-unit or small-carton step for each of eight or nine line items. So the per-kit component cost of self-assembly is structurally higher at low volume, and the assembly labor sits on top of it rather than replacing it.

There is a limit to that argument. It holds for the consumables inside the kit, and it does not hold for the pouch itself or for items you already stock in volume for other reasons. A buyer who already purchases tourniquets by the carton for training is in a different position from one starting cold.

Two questions settle it for most buyers. How many kits? Below a few dozen, assembling rarely pays for the effort. Who owns the rotation? If nobody in your organization will actually track expiries kit by kit, buying assembled from a supplier who dates the unit is the safer route, because the failure mode of self-assembly is a shelf full of kits nobody has opened in three years.

Whichever route you pick, the verification questions are the same. They just go to a component supplier instead of a kit supplier.

What to Verify Before You Order

Five questions, all answerable with documents.

1. Which recommended class does each device belong to? Ask the supplier to name the active agent in the hemostatic gauze and the class of the tourniquet. A supplier who can name them can also show you where they sit in the guidelines. One who cannot name them has told you something useful.

2. Cleared, or registered? For the hemostatic dressing specifically, these are regulated devices. In the United States they reach the market through FDA clearance under a specific product code. “FDA registered” is a listing obligation and is not clearance. Ask for the clearance, not the registration.

For example, put this question to two suppliers and the answers separate them immediately. One returns a clearance number you can look up yourself. The other answers “FDA registered factory”, which is neither the number nor the right word. You have not learned whether that product is compliant. You have learned that the person selling it cannot tell the two apart.

3. What is the shelf life, and what storage does it assume? Get the number in writing along with the conditions it was validated under. Consumables with an expiry are a rotation problem, not a one-time purchase, and the storage envelope is the part suppliers most often leave verbal.

4. How is each item packaged, and where is it expected to ride? This is the question buyers skip, and the earlier section gave it a measured answer: externally carried tourniquets tested at 57% efficacy against a 95.2% control, with 12% breaking outright, while the same tourniquets stored inside the kit matched the control. Ask how the kit is compartmented, whether the tourniquet sits in a closed section, and what the supplier recommends for units that will be carried externally anyway.

5. Is there a stock number or traceable batch documentation? For institutional buyers a national stock number settles a lot of arguments. For everyone else, a certificate of analysis per lot is the equivalent question. If you are buying OEM or private label, add one more: whose clearance the product ships under, because clearance belongs to a named legal manufacturer and your label does not inherit it automatically.

Why documents rather than assurances. Each of the five questions asks for something that exists independently of the seller: a clearance number sits in a public database, a validation report exists because a regulator required it, a lot certificate is generated by the process rather than by the sales conversation. That is the mechanism behind the test. It is not that documents are more truthful than people. It is that a document had to be produced by someone other than the person answering your email, so a supplier who cannot produce one is telling you something about their position in the supply chain rather than about their honesty.

Which of the five bind hardest depends on who you are. An institutional buyer with a compliance function will care most about clearance and stock numbers, because those are what an auditor asks for. A small team buying for its own use will get more value from the storage envelope and the carry question, because those change how long the kit stays serviceable. Compared with a price negotiation, all five are cheap: they cost one email and they reprice the whole comparison.

Notice what these five have in common. A real manufacturer answers them with documents. A reseller answers them with adjectives. Ask them before the minimum-order and lead-time conversation rather than after, because unit cost and carton quantities are easier to negotiate once a supplier knows the documents will be checked. And run the Two-Number Test before any of them, because the five questions settle which kit to buy, not how many.

We manufacture components that go into kits like these, which puts us on the supplier side of this table, and is exactly why we suggest you ask us the same five questions. For bulk and OEM sourcing of trauma kits and components, see our medical kits and components page.

Frequently Asked Questions

What is the difference between an IFAK and an AFAK?

An IFAK is one person’s kit for treating that person. An AFAK is generally positioned as an augmented kit carrying more than one casualty’s worth of consumables. The naming is not standardized between vendors, so check the actual contents and quantities rather than the acronym. The practical test is quantity against your expected casualty count, which is the same test that decides whether one kit per person is enough at all.

What is an IFAK in the military?

The same idea with a formal supply chain behind it. Military IFAKs are issued to individuals as the first echelon of medical capability, sitting below the medic’s bag and the casualty evacuation set. The USSOCOM CASEVAC Set program that developed the modern version was explicitly built in those three steps, starting with an improved IFAK in 2006. One consequence follows for civilian buyers: an issued military kit is sized for a system that has the other two echelons behind it.

What should be in your IFAK?

Build the contents in the order the guidelines treat a casualty: massive hemorrhage, then airway, then respiration. Check each device against the CoTCCC recommended classes rather than a vendor’s list. Then match the quantity to your expected casualty count and evacuation time rather than to a standard packing list. And decide where the tourniquet rides, because the measured difference between carrying it inside the kit and strapped outside it is larger than the difference between most brands.
