Which First Aid Kit Do You Need? Complete Buyer's Guide (2026)

Which First Aid Kit Do You Need? Complete Buyer's Guide (2026)

Published July 2, 2026 · Last updated July 27, 2026

For a structured pass over your own headcount and hazards, run the first aid kit selector — it applies the mapping this guide explains.

Which first aid kit you need comes down to one question: where will it be used, and what can go wrong there? A 10-person office, a 50-person plant, a fleet truck, a jobsite with saws and heights, and a backpack on a trail each call for a different kit — different fill, different container, different restocking plan. This guide walks every major scenario and names a specific, stocked product for each, so you can buy once and buy right. For most workplaces, the starting point is the First Aid Only 746000 SmartCompliance 50-Person ANSI A+ First Aid Cabinet — a wall-mountable cabinet with an ANSI/ISEA Z308.1 Class A+ fill and built-in refill reminders.

Quick Answer: Match the Kit to the Environment

First aid kits are not interchangeable. The fill inside an ANSI-compliant workplace kit is built around common occupational injuries — cuts, abrasions, minor burns, eye irritation — while a trauma kit is built around one job: stopping severe bleeding fast. An outdoor kit trades cabinet-scale quantities for weight and waterproofing. Buying the wrong type means either paying for supplies you will never use or, worse, reaching for a kit that does not contain what the injury in front of you demands.

Here is the short version, before we go deep on each scenario:

Every one of these scenarios gets a full section below, and each section links to the ranked buyer's guide for that category if you want to compare more than one option. The full catalog lives in our First Aid Kits collection.

Class A vs Class B: The 60-Second Version

Two documents govern workplace first aid buying in the United States. OSHA 29 CFR 1910.151 requires that adequate first aid supplies be readily available where no clinic or hospital is in near proximity, and its Appendix A points to ANSI/ISEA Z308.1 as the reference standard for what "adequate" looks like. ANSI/ISEA Z308.1-2021 then defines two fill classes and four container types:

• Class A — supplies for the most common workplace injuries: minor cuts, abrasions, minor burns, eye irritation. The default for offices, retail, and low-risk shops.
• Class B — a broader and higher-quantity fill for higher-risk environments: manufacturing, warehousing, construction. More dressings, more bandage variety, a splint and tourniquet in the mix.
• Type I–IV containers — from indoor wall-mount (Type I/II) through portable, mountable, water-resistant (Type III) to outdoor-rated (Type IV).

That is the entire summary on purpose. The full regulatory decode — what 1910.151 actually obligates you to do, how Z308.1-2021 item counts break down line by line, what OSHA 1926.50 adds for construction, and how citations actually get written — lives in our dedicated reference explainer: OSHA First Aid Kit Requirements: 29 CFR 1910.151 and ANSI Z308.1 Explained. Read that when you need chapter and verse for a compliance file. Stay here when the question is what to actually buy.

Workplace Kits: Kit vs Cabinet, Sizing by Headcount

Workplace buyers face two decisions in sequence: portable kit or wall-mounted cabinet, and what size for the headcount. Get these right and the rest of the program is just restocking. Once the kit is in service, our first aid kit inspection checklist covers the maintenance side.

Sizing by headcount

Up to 10 people. A compact Class A kit covers a small office, food truck, or crew van. The ProHeal 10-Person ANSI Class A kit and the budget Ever Ready 10-Person Class A kit both carry the Z308.1 Class A fill in a case small enough to live in a drawer or on a van shelf.

10 to 25 people. Step up to a 25-person fill. On jobsites, the First Aid Only 9302-25M contractor kit is the field favorite — a rugged metal case built to mount in the truck or shop and take jobsite abuse.

25 to 50 people. This is cabinet territory. The First Aid Only 746000 SmartCompliance cabinet is our primary workplace recommendation for a reason: the ANSI A+ fill covers 50 people, and the SmartTab ezRefill system flags spent supplies so restocking never silently lapses — the most common failure mode of workplace first aid programs. Our full 746000 review covers the fill list and mounting. Prefer a portable case at this headcount? The SmartCompliance 50-person kit carries the same refill-reminder logic in a carry format — see the SmartCompliance 50-person kit review for how the two compare. A leaner option at the same headcount is the First Aid Only 91248 OSHA-compliant 50-person kit.

50 to 150 people. Multi-shelf metal cabinets, stocked to Class B for industrial sites. The First Aid Only 90575 3-shelf ANSI B+ cabinet serves 100–150 employees; the UniShield 4-shelf Class B cabinet adds a shelf of capacity for high-risk plants; and the RHINO RESCUE 371-piece OSHA 100-person kit covers the same headcount in a portable format at a value price. Kitchens have their own variant — the UniShield restaurant cabinet builds blue detectable bandages and burn care into a Class B fill.

For the full ranked field — ten-plus kits scored on fill, container, and restocking cost — see Best Workplace First Aid Kits (ANSI Class A & B) and Best First Aid Cabinets & Wall-Mount Stations. Multi-site and multi-cabinet buyers ordering at volume can skip the cart entirely — and we will spec the program.

Vehicle & Fleet First Aid Kits

A vehicle kit is not a workplace kit that happens to ride in a truck. It has to stay put under braking, survive temperature swings, and be findable by someone who has never opened it. That means a mountable case, organized internal layout, and a fill matched to road and roadside injuries.

Fleet and work-truck spec

For fleet vehicles, buy to a standard: the MFASCO vehicle first aid kit is DOT, ANSI, and OSHA compliant in a metal case that bolts into work trucks, vans, and fleet vehicles — the default answer for fleet managers standardizing across vehicles. Our MFASCO vehicle kit review covers mounting and fill detail.

Personal vehicles, RVs, and boats

For personal trucks, RVs, and boats, waterproof hard-shell kits earn their keep: the Gevoke 410-piece hard-shell kit and the THRIAID 430-piece waterproof kit both organize high piece counts into trays that survive being thrown around a cargo area. The soft-sided KeepGoing travel kit splits the difference for car-plus-trail use. Compare the whole field in the Vehicle First Aid Kits collection and the ranked Best Vehicle & Truck First Aid Kits guide.

One upgrade worth making on any work vehicle: pair the first aid kit with a vehicle-mounted trauma kit. The RHINO RESCUE Vehicle IFAK straps a C-A-T tourniquet and trauma supplies to a headrest or seat back where they can be reached in seconds — which brings us to the layer most first aid programs miss entirely.

Trauma Kits & Bleeding Control: The Layer Most Programs Miss

Standard first aid kits — even Class B — are built around common injuries. Severe, life-threatening bleeding is a different problem on a different clock, and it is why bleeding control equipment deserves its own line in every jobsite budget. ANSI Z308.1-2021 acknowledged this reality by including a tourniquet in the Class B fill, but a single tourniquet buried in a cabinet drawer is not a bleeding control program. Sites with saws, blades, powered equipment, glass, or vehicle traffic should stage dedicated, clearly marked bleeding control kits alongside — not inside — the first aid cabinet.

Public-access bleeding control

The benchmark is the North American Rescue Public Access Bleeding Control Kit — a vacuum-sealed, clearly labeled kit built around the C-A-T tourniquet, emergency trauma dressing, and compressed gauze, designed for Stop-the-Bleed-style station mounting. Our full NAR kit review breaks down the contents. The leaner NAR Individual Bleeding Control Kit covers job boxes and range bags at a lower price.

IFAKs for crews and vehicles

An IFAK — individual first aid kit — puts trauma supplies on the person or vehicle rather than the wall. The RHINO RESCUE IFAK with C-A-T tourniquet is MOLLE-mountable with an Israeli bandage and chest seal in the fill; the Scherber Premium IFAK is the fully stocked step-up. Individual components restock the layer: the RHINO RESCUE 6-inch Israeli-style bandage and the NAR Z-fold wound packing gauze are the two consumables most worth keeping spares of.

The full category — kits, dressings, chest seals, and refills, ranked — is in Best Trauma Kits & IFAKs and the Trauma Kits & Bleeding Control collection. Crews working at height have one more trauma-adjacent item to stage: suspension trauma straps for post-fall harness suspension. And if you are building out a full jobsite program, the Construction Site PPE hub maps first aid into the rest of the PPE stack.

Burn Care: Staging Dressings Where Burns Happen

Burn injuries reward proximity. A gel burn dressing in the kitchen or next to the welding bay gets used in the first minute; the same dressing in a cabinet two rooms away often does not. That is why burn care is a staging decision, not just a purchasing decision: buy dressings sized to the burns your site can produce, and mount them at the hazard.

Sizing the dressing to the hazard

For kitchens and shops where fingers, hands, and wrists take the contact burns, the Water-Jel 2x6 five-pack is the standard restock. For hot-work areas where a full forearm or leg can be exposed — welding, steam, hot fluids — stage the Water-Jel 4x16 large-format dressing; our Water-Jel 4x16 review explains when the large format earns its price. The RHINO RESCUE burn kit packages dressings, gel packets, and pads into a complete burn station in a pouch, and Burn-Fix hydrogel packets are the high-count cabinet restock. Note that burn gels and dressings are FDA-regulated OTC products — use them per their labeling, and treat anything beyond minor burns as a medical-response event, not a first aid event.

The ranked field is in Best Burn Care Kits & Dressings, and the full range lives in the Burn Care collection.

Eyewash: Bottles, Stations, and When ANSI Z358.1 Applies

Eyewash splits into two very different purchases. Personal eyewash — bottles like the PhysiciansCare sterile eye wash solution or the double-bottle PhysiciansCare wall-mount station — supplements a first aid program and handles dust and minor irritants. But where corrosive or injurious chemicals are in use, ANSI/ISEA Z358.1 requires plumbed or self-contained equipment capable of a 15-minute flush — a bar that bottles do not meet. Self-contained gravity-fed units like the Frifreego 8-gallon station and the Magula 9-gallon station exist precisely for work areas plumbing cannot reach.

Whether Z358.1 applies to your site, flush-duration and water-temperature requirements, placement rules, and weekly activation checks are all covered in the dedicated explainer — What Is ANSI Z358.1? Emergency Eyewash Station Requirements — which is the page to read before you spec a station. For hardware comparisons, see Best Portable Eyewash Stations and the Eyewash Stations collection.

Refills, Bandages & Restocking Economics

A first aid program's real cost is not the kit — it is the decade of restocking that follows. Buyers who ignore this end up doing the expensive thing by default: replacing whole kits because the bandage compartment ran dry.

Refill, don't replace

Class-matched refill packs restore a kit or cabinet to its full ANSI fill for a fraction of replacement cost. The Urgent First Aid Class A 25-person refill (78 pieces) and its Class B 50-person counterpart (208 pieces) cover most kits; the First Aid Only 90583 factory refill restores First Aid Only 25-person kits to their original fill; and the UniShield Class B refill with medications restocks an entire multi-shelf cabinet without replacing it. Trauma layers restock too: the RHINO RESCUE IFAK refill with CAT Gen-7 rebuilds a used or expired IFAK around a fresh tourniquet. The whole category is in First Aid Kit Refills.

The consumables that actually run out

Adhesive bandages are the highest-turnover item in any kit, so buy them in bulk rather than through kit-sized packets. Dynarex 3611 fabric bandages are the workhorse bulk-box restock; Band-Aid flexible fabric bandages are the reference brand for hand-heavy work; and food processing and commercial kitchens should standardize on Curad blue detectable knuckle bandages, which are visually and metal-detectably findable if one ends up where it should not. Larger wounds draw from island dressings and non-stick pads — all under Bandages & Wound Care.

The CPR layer

Every kit and AED station should carry a barrier device. The WNL CPR rescue mask in its hard case is the single-station standard; the MCR Medical 5-pack stocks multi-station facilities and training programs. See the full CPR & Rescue Supplies collection.

Outdoor & Personal Kits

Outdoor kits optimize for the opposite constraints of workplace kits: every ounce counts, water is the enemy, and the nearest help may be hours away. Buy by trip profile, not piece count.

Matching the kit to the trip

Day hikes and trail runs (1–2 people): the Adventure Medical Kits Ultralight/Watertight .5 weighs under four ounces and disappears into a running vest. Full-day and overnight outings (2 people): the AMK Mountain Series Hiker organizes supplies by injury type — our Mountain Hiker review details the layout. Multi-day backpacking: the Mountain Series Backpacker extends the same system for two people over multiple days. Hunting and backcountry groups: the Sportsman Series 200 adds field trauma supplies including a trauma pad for groups up to four. Everyday carry and travel: the Johnson & Johnson travel 3-pack covers glovebox, desk, and carry-on in one buy.

The ranked comparison is in Best Hiking & Outdoor First Aid Kits, and the category lives at Outdoor & Personal First Aid Kits.
