First Aid Cabinets & Stations — Class A, Class B and Empty

Which first aid cabinet should your facility buy in 2026?

Short answer: For most facilities of 100-150 people, the First Aid Only 90575 3-Shelf ANSI B+ First Aid Cabinet — a metal wall station with a Class B+ fill and the deepest refill ecosystem in the category. High-consumption industrial floors that need a fourth shelf should look at the UniShield 4-Shelf Metal First Aid Cabinet, ANSI Class B, and offices get a right-sized fill in the UniShield 3-Shelf Metal First Aid Cabinet, ANSI Class A. The first aid kit selector sizes the class and format; container duty ratings are decoded in ANSI first aid kit types explained.

First Aid Cabinets & Stations (2026)

A first aid cabinet is what a workplace kit grows into: a fixed, wall-mounted supply station organized shelf by shelf, restocked by tray instead of replaced. This collection sits inside our First Aid Kits category and holds 7 metal wall-mount cabinets spanning ANSI Class A, Class B, and Class B+ fills. If one supply point serves under ~100 people, a kit from Workplace First Aid Kits is usually the better buy; whichever format you run, the restocking side lives in First Aid Kit Refills.

How to choose a first aid cabinet

Confirm the format first

The cabinet threshold is roughly 100 people per supply point, several departments sharing one station, or consumption that empties kit trays between checks. Below that line, the money is better spent in our Workplace First Aid Kits collection; the full ranking logic is in the Best First Aid Cabinets & Wall-Mount Stations buyer's guide.

Match the fill class to the floor

ANSI Z308.1-2021 assigns Class A to common workplace injuries in lower-risk environments and Class B to larger workforces and high-risk floors. Class the cabinet to the highest-risk zone it serves: machinery, heights, or heavy material handling all point to Class B or B+.

Size shelves to consumption, not headcount alone

Three shelves cover most single-shift facilities. Choose four — the UniShield 4-Shelf Metal Cabinet or the restaurant variant — when multiple shifts or high-turnover injuries would drain a 3-shelf station mid-cycle.

Check the restock path before you buy

A cabinet is a container plus a subscription. The 90575 restocks from First Aid Only's factory line, and every cabinet here accepts class-matched packs from the First Aid Kit Refills collection — buy the refill plan with the cabinet.

OSHA and ANSI requirements for first aid cabinets

One thing to clear up first, because the whole category is marketed on it: an ANSI class is not a headcount. Z308.1 sets minimum contents by class — Class A for the common workplace injuries of a lower-risk setting, Class B with greater quantity and variety for higher-risk or more populous ones — and neither letter carries a number of people. The "50 Person" and "100 Person" labels that appear on some listings are a vendor convention for pack size, not an ANSI designation, and we repeat them only as the manufacturer states them.

How many kits your workplace needs is a question of distance and response time, not arithmetic on headcount — that is what "readily available" in 1910.151(b) actually turns on. One Class B cabinet at the far end of a building serves nobody at the other end.

No OSHA rule names "cabinet". 29 CFR 1910.151(b) requires adequate first aid supplies to be readily available, and its non-mandatory Appendix A points at ANSI/ISEA Z308.1, which defines the Class A and Class B fills those supplies are judged against. On construction sites 29 CFR 1926.50 carries the equivalent duty. NIOSH publishes the workplace-injury research underneath both. The cabinet is simply the container format that keeps a large fill compliant in practice: fixed, visible, organized shelf by shelf. The full decode — fill tables, container types, construction's 1926.50 rule — lives in our reference explainer, OSHA First Aid Kit Requirements, and this page defers all regulatory detail to it.

Pairs with this collection

Round out the station wall: class-matched restocks from First Aid Kit Refills, satellite kits from Workplace First Aid Kits for zones beyond a 3-4 minute walk, a bleeding control kit from Trauma Kits & Bleeding Control mounted beside the cabinet on high-risk floors, an eyewash station where chemical exposure requires one, and bulk dressings from Bandages & Wound Care. Kitchens should add depth from Burn Care.

Total cost of ownership

Budget the refills, not just the box. A stocked cabinet runs the range here up front, then consumes class-matched refills on a quarterly cycle — the UniShield ANSI Class B First Aid Refill with Medications is sized to restock a 3- or 4-shelf cabinet in one order, while the Urgent First Aid ANSI Class A Refill Kit handles Class A stations. Restocking an existing cabinet with a refill beats re-buying the station every year — that math is the whole case for the cabinet format.

Why do most of these cabinets have no ANSI class at all?

Because a class describes the contents, not the box. Of the twenty cabinets here, three state Class A, three state Class B, two use the vendor term "B+", and twelve state no class whatsoever. Every one of them is a first aid cabinet wall mounted to a fixed surface rather than a portable case, and several are a lockable first aid cabinet with a keyed or latching door — which matters where medication-adjacent supplies need controlling. Three of those twelve are sold explicitly empty.

That is not a defect in the listings — it is what the products are. An empty steel cabinet is a mounting and organizing solution, and it has no ANSI class because there is nothing in it to classify. Buying one moves you toward compliance with nothing until you fill it, and the fill is where both the cost and the standard live.

So the comparison to avoid is a cheap empty cabinet against an expensive filled one, concluding the empty is better value. They are answers to different questions:

• Buy filled if you want a defensible Class A or Class B assortment on the wall from day one and do not already have a supply arrangement.
• Buy empty if you already restock from bulk or a supplier, or you are consolidating loose supplies that are currently in three drawers.

Either way the cabinet is not the compliance item. The refills are, and OSHA first aid kit requirements has the Z308.1 fill tables.

Class is one axis — Type is the other

Z308.1 classifies the container as well as the fill, and the container types are worth knowing because they decide where a kit may live:

• Type I — stationary, indoor. Intended to be mounted and left there.
• Type II — portable, indoor.
• Type III — mountable and water-resistant, indoor or outdoor.
• Type IV — mobile and outdoor, with impact and corrosion resistance for vehicles and rough environments.

Every cabinet on this page is a Type I wall enclosure. If you need a Class B fill in a truck, on a trailer or anywhere weather reaches it, the fill class is right and the container type is wrong — look at vehicle first aid kits or outdoor first aid kits instead. A steel wall cabinet in a vehicle is not a compliant Type IV container no matter what is inside it.

Two cabinets here that are not first aid cabinets

Worth flagging so you do not order one by mistake. One member is an AED cabinet — a wall enclosure sized and often alarmed for a defibrillator, not for first aid supplies. If that is what you want, AEDs and AED accessories are the right place. Another is an overdose emergency cabinet, built for naloxone response rather than general first aid. Both are legitimate products; neither is a Class A or Class B first aid cabinet.

First aid cabinet FAQ

What is a first aid cabinet, and how is it different from a first aid kit?

A cabinet is a fixed, wall-mounted metal station with open shelves, restocked tray by tray; a kit is a portable sealed case. Cabinets win past ~100 people per supply point; kits win for mobile crews and satellite zones. The pillar guide Which First Aid Kit Do You Need? maps the crossover.

Which first aid cabinet is best for a 100-150 person facility?

The First Aid Only 90575 — its ANSI B+ fill carries a stated 100-150 person rating, the only cabinet in this collection with that band on the listing.

Is "Class B+" an ANSI class?

No. ANSI/ISEA Z308.1-2021 recognizes two fill classes: Class A and Class B. There is no Class B+ in the standard. "B+" is a manufacturer's shorthand for a Class B assortment plus extra items beyond the minimum, and it carries no standing in Z308.1 — two makers use it in their own product titles, and we quote it as listed rather than adopting it. What it does tell you is directional: the fill starts from the Class B baseline rather than Class A. Both the 90575 and the EVERLIT CARE 203SFAK100 carry B+ fills.

Which cabinet here fits an office or low-risk workplace?

The UniShield 3-Shelf Metal Class A — station capacity with a Class A fill, so you are not paying for (or letting expire) trauma-depth supplies an office will never use.

What makes a restaurant first aid cabinet different?

The fill. The UniShield Restaurant cabinet stocks blue detectable bandages — visible if a dressing falls into food — and burn care for the kitchen's actual injury profile. Standalone restocks: Curad Blue Detectable Knuckle Bandages.

How often should a first aid cabinet be restocked?

Check quarterly and after every recordable injury; restock from class-matched packs in the first aid kit refills collection rather than re-buying the station.

Can I restock these cabinets with any brand's refills?

Yes — shelves take any class-matched stock. Keep the refill's packing list with your program records so the fill stays documented to Class A or B; the MFASCO Class A refill pack and Urgent First Aid Class B refill both publish theirs.

Does an ANSI class tell me how many employees it covers?

No. Z308.1 defines minimum contents by class, not by headcount. The "50 Person" or "100 Person" labels on some listings are a vendor convention for pack size. How many kits you need follows from OSHA 1910.151(b)'s "readily available" requirement, which is about distance and response time rather than a ratio of people to boxes.

Do empty cabinets have an ANSI class?

No — the class describes the contents, so an empty cabinet has none. Three of the twenty here are sold empty and twelve state no class at all. An empty cabinet is a mounting and organizing solution; the fill is where the standard applies.

What is the difference between Class and Type?

Class is the fill — A or B. Type is the container: Type I stationary indoor, Type II portable indoor, Type III mountable and water-resistant, Type IV mobile and outdoor with impact and corrosion resistance. Every cabinet on this page is Type I, so a Class B fill in a wall cabinet does not satisfy a Type IV requirement for a vehicle.

Does OSHA require a first aid cabinet specifically?

No — OSHA 1910.151 requires adequate, readily available supplies and leaves the container to you. The cabinet format is how large facilities meet "readily available" in practice. Full decode in the OSHA first aid kit requirements reference.

Which is the budget cabinet in this collection?

The Medique 712MTM — the classic 3-shelf shop cabinet with door pockets. Its fill is not stated to an ANSI class, so pair it with a documented refill to bring it to standard.

Do first aid cabinets come with medications?

Some fills include OTC medications and some employers exclude them by policy. If your program allows them, the UniShield Class B refill with medications restocks that tray; stock only unopened, labeled OTC products. Nothing on this page is medical advice.

Should a trauma kit hang next to the cabinet?

On floors with severe-laceration or crush exposure, yes — cabinet fills handle everyday injuries while dedicated bleeding control is a separate capability. See the Best Trauma Kits & IFAKs guide for the station-mount options.

Our methodology: what is on this page, and what it cannot do

We counted this collection against the storefront and read all twenty product titles before describing it, which is why the class breakdown above is a count rather than an impression: three Class A, three Class B, two using the vendor term "B+", twelve stating no class, and three sold explicitly empty. We judge attributes from titles and listing data only, never from the shared descriptive copy that repeats across product pages. Two corrections came out of that and are stated rather than smoothed over: "B+" is not an ANSI class, and an ANSI class is not a headcount — both are manufacturer conventions we quote as listed without adopting. Piece counts and fill claims are the manufacturers' published figures; we do not open cabinets or audit contents against the Z308.1 tables, so where a listing says Class B we report the claim, not a verification. And we do not tell you which class your workplace needs — that follows from your hazard assessment under 1910.151, and the standard's own tables are in the reference guide we link rather than paraphrased into advice here.
