First Aid Only 90575 3-Shelf ANSI B+ First Aid Cabinet, 100-150 Person Review (2026)

Is the First Aid Only 90575 the right first aid cabinet for a 100-150 person facility?

Short answer: Yes — if you need a brand-name, high-capacity wall station, the First Aid Only 90575 is the strongest all-around cabinet in our first aid lineup. It is a metal 3-shelf station with an ANSI B+ fill that the manufacturer lists for 100-150 employees, which is the highest stated coverage of any cabinet we stock. Budget buyers should look at the Medique 712MTM, and kitchens should look at the UniShield 4-Shelf Restaurant Cabinet — but for a general warehouse, plant, or distribution center, this is the default pick.

First aid cabinets are the backbone of a workplace first aid program: unlike a portable kit that walks off in a truck, a wall-mounted station stays put, stays visible, and gets restocked rather than replaced. This review looks at how the First Aid Only 90575 fits that role — its stated capacity, its ANSI B+ fill, how it compares against the other six cabinets in our first aid cabinets collection, and what it costs to keep stocked over time. If you are still deciding between a cabinet and a portable kit, start with our which first aid kit do you need pillar guide; for the full ranked field, see the best first aid cabinets buyer's guide.

Editorial verdict: 4.6/5. The First Aid Only 90575 combines the highest stated employee coverage in our cabinet lineup (100-150 person) with an ANSI B+ fill and a proven brand refill ecosystem, at a mid-pack $143.87. It is the cabinet we would put on the wall of most large facilities.

Who the First Aid Only 90575 is for

• Warehouse and plant safety managers covering 100+ employees from a central, fixed first aid point
• Multi-shift facilities that need a station employees can find in the same place on every shift
• Buyers standardizing on one brand — First Aid Only sits behind several kits in our workplace first aid kits collection, so one vendor covers stations and satellite kits
• Programs built around OSHA/ANSI compliance — the B+ fill maps to the higher-risk Class B end of ANSI Z308.1; our OSHA first aid kit requirements explained reference covers exactly what 29 CFR 1910.151 and Z308.1 expect

What the First Aid Only 90575 does well

Stated 100-150 person coverage — the biggest number in our cabinet set

Most cabinets in our lineup either state 100-person coverage or none at all. The First Aid Only 90575 is listed for 100-150 employees, which makes it the only cabinet we stock with a stated range beyond 100. For a facility running 120 or 140 heads, that listed range matters: it lets you document a defensible basis for your station sizing instead of extrapolating from a 100-person rating.

ANSI B+ fill for higher-risk environments

The manufacturer lists the 90575 as an ANSI B+ cabinet — a Class B fill plus supplementary items, as marketed. Class B is the ANSI Z308.1 designation aimed at larger workforces and higher-risk environments, which is precisely the population a 100-150 person warehouse or plant represents. We defer the full Class A vs Class B breakdown to our OSHA first aid kit requirements reference rather than repeat it here.

The industry-standard metal 3-shelf station format

The 3-shelf metal wall cabinet is the format plant maintenance teams already know: swing door, shelf rows visible at a glance, supplies grouped by shelf. That familiarity is worth something — a station format everyone recognizes gets used and gets restocked. It also mounts at eye level in a hallway or break area where OSHA's "readily available" expectation is easy to satisfy.

A refill ecosystem behind the brand

Cabinets are refilled, not replaced — and First Aid Only is one of the easiest brands to restock. We carry the First Aid Only 90583 25-Person Refill alongside the broader first aid kit refills collection, so keeping the shelves full never depends on a single SKU staying in stock.

Sensible price for the capacity

At $143.87 the 90575 sits mid-pack in our cabinet lineup — above the budget Medique and EVERLIT CARE stations, below the UniShield 4-shelf cabinets. On a per-covered-employee basis, its stated 100-150 person range makes it arguably the best value of the group: roughly a dollar per employee covered at the top of its range.

Where the First Aid Only 90575 falls short

The steel box alone is cheaper elsewhere

If what you really want is the classic shop cabinet format and you plan to stock it yourself, the Medique 712MTM 3-Shelf Cabinet delivers that format for $71.69 — half the price. You give up the stated B+ fill and the 100-150 person rating, but self-stockers should run that math.

Three shelves has a ceiling

A 3-shelf cabinet organizes a Class B fill fine, but if your program adds burn care modules, eye care, and over-the-counter medications on top, shelf space runs out. The UniShield 4-Shelf Metal Cabinet exists for exactly that growth path.

More cabinet than small sites need

For a 10-25 person office, a B+ station for 150 is simply the wrong tool — a wall-mount Class A kit from our workplace first aid kits line costs a third as much and satisfies the same obligation for that headcount.

First Aid Only 90575 vs the competitive set

Here is how the 90575 lines up against every other cabinet in our first aid kits parent collection, compared on the three axes that matter for a station purchase: shelf count, ANSI class as listed, and stated employee capacity.

First Aid Only 90575 vs EVERLIT CARE 203SFAK100 vs MFASCO Class B — the 3-shelf Class B shootout

The 90575's closest rivals are the other two 3-shelf Class B/B+ stations. All three put a Class B-scope fill in a metal wall cabinet; the differences are stated capacity, brand maturity, and price. The reviews for both rivals go deeper: see our EVERLIT CARE 203SFAK100 review and our MFASCO Class B 3-Shelf Cabinet review.

• Buy the First Aid Only 90575 if your headcount runs past 100 and you want the stated 100-150 rating plus the deepest refill ecosystem.
• Buy the EVERLIT CARE 203SFAK100 if you cover 100 or fewer and want the lowest price on a stated B+ station.
• Buy the MFASCO Class B if an explicit ANSI Z308.1-2021 Class B callout and same-brand refill packs matter more than the sticker price.

Refills and companion products — cabinets are restocked, not replaced

The whole point of a cabinet purchase is that you buy the station once and then feed it consumables. Plan the restocking loop on day one: the same-brand First Aid Only 90583 25-Person Refill is the natural match here, and the Urgent First Aid Class B Refill, 50 Person restocks the Class B side in one box. Browse the full first aid kit refills collection for the rest. Facilities placing a central station usually also hang satellite coverage — a compact unit from the workplace first aid kits collection such as the First Aid Only 746000 SmartCompliance Cabinet keeps break rooms and mezzanines covered between the main station and the work.

Cabinet or kit? Where the 90575 sits in the category

A wall cabinet like the 90575 is the right call when the workforce is fixed and the location is permanent. Crews that move — construction, field service, fleets — are better served by portable kits, which is the split our which first aid kit do you need guide walks through in detail. Within the cabinet subcategory, the 90575's B+ fill puts it on the industrial end of the spectrum, in the same tier as the UniShield Class B cabinets and above office-grade Class A stations. For the regulatory logic that decides between Class A and Class B — headcount, hazard profile, distance to care — rely on the OSHA first aid kit requirements reference rather than any marketing copy, including ours.

Total cost of ownership

At $143.87 up front, the 90575 is a one-time buy; the recurring cost is consumables. In practice the fast-moving items in any station are adhesive bandages, wound dressings, and gloves — the same categories our bandages and wound care collection restocks individually, often cheaper than full refill packs once you know your burn rate. A sensible program budgets one refill cycle per quarter for a 100+ person facility and audits the shelves monthly. Amortized over a five-year service life, the cabinet itself costs under $30 a year — the fill discipline, not the hardware, is where the money goes.

Final verdict: 4.6/5

The First Aid Only 90575 is the best all-around first aid cabinet we stock for large facilities. The stated 100-150 person coverage is unique in our lineup, the ANSI B+ fill matches the risk profile of the buildings it belongs in, and the brand's refill ecosystem keeps the long-term ownership story simple. Buy the EVERLIT CARE 203SFAK100 cabinet if you want stated B+ coverage for the absolute least money; buy the 90575 if you want the bigger stated range and the safer brand bet.

First Aid Only 90575 — frequently asked questions

Is the First Aid Only 90575 OSHA compliant?

OSHA 29 CFR 1910.151 requires adequate first aid supplies to be readily available but does not certify products; its Appendix A points to ANSI Z308.1 as the benchmark. The First Aid Only 90575 is marketed with an ANSI B+ fill, which maps to that benchmark's higher-risk class — see our OSHA first aid kit requirements guide for how to document compliance.

How many employees does the First Aid Only 90575 cover?

The manufacturer lists the 90575 for 100-150 employees, the highest stated coverage of any cabinet in our first aid cabinets lineup. Actual adequacy also depends on hazard level and how quickly supplies are consumed, so audit the shelves against your own incident history.

What does ANSI B+ mean on the First Aid Only 90575?

Class B is the ANSI/ISEA Z308.1 fill intended for larger workforces and higher-risk environments; the "+" is the manufacturer's designation for a Class B fill with supplementary items beyond the minimum. It is a marketing label built on the ANSI class, not a separate ANSI category.

First Aid Only 90575 vs EVERLIT CARE 203SFAK100 — which should I buy?

Buy the 90575 for headcounts above 100 and for the more established refill ecosystem; buy the EVERLIT CARE 203SFAK100 to save about $5 on a stated 100-person B+ station. Our EVERLIT CARE cabinet review covers the budget side in full.

First Aid Only 90575 vs Medique 712MTM — is the price gap justified?

They solve different problems. The 90575 arrives with a stated B+ fill and a 100-150 person rating; the Medique 712MTM review covers a $71.69 cabinet whose listing states no fill class — it is the pick for self-stockers, not turnkey compliance.

Is the First Aid Only 90575 enough for a warehouse with forklift and racking hazards?

Its B+ fill targets exactly that higher-risk profile, and warehouses are the environment the 100-150 person rating fits. Pair the central station with satellite kits from the workplace first aid kits range so treatment supplies are never more than a short walk away.

Does the First Aid Only 90575 need a separate eyewash station?

Yes, where chemicals or flying-particle hazards exist — a first aid cabinet does not substitute for emergency eyewash. See the eyewash stations collection, and note that units like the PhysiciansCare Wall-Mount Eyewash Station mount right beside a cabinet.

How do I restock the First Aid Only 90575?

Cabinets are restocked item-by-item or with refill packs rather than replaced. The First Aid Only 90583 refill keeps you in the same brand, and the refills collection carries multi-brand alternatives sized by headcount.

Where should the First Aid Only 90575 be mounted?

On a wall in a high-traffic, well-lit area every shift can reach without keys or obstacles — break rooms, main corridors, and shipping offices are typical. OSHA expects supplies to be "readily available," so avoid locked offices and remote mezzanines.

Does the First Aid Only 90575 come with mounting hardware?

The listing does not specify included hardware, so plan on sourcing anchors or lag bolts appropriate to your wall construction. A loaded metal cabinet carries real weight — anchor into studs or masonry, not drywall alone.

Is the First Aid Only 90575 suitable for a construction site?

For a fixed site office or a long-running project with a permanent trailer, yes — construction first aid falls under OSHA 1926.50, which our OSHA first aid requirements reference also covers. Mobile crews are usually better served by portable kits from the best workplace first aid kits guide.

What is the difference between the First Aid Only 90575 and a 4-shelf cabinet?

Shelf real estate. Our UniShield 4-Shelf Metal Cabinet review covers the main 4-shelf alternative — the extra shelf suits programs that add burn modules, eye care, and medications beyond the base fill, at a $46 premium over the 90575.

Can the First Aid Only 90575 serve multiple buildings?

One station should serve one building or work zone; walking time between buildings defeats the point of ready access. Standardize on the same cabinet across buildings instead, so restocking and audits use one checklist.

How often should the First Aid Only 90575 be inspected?

Monthly shelf audits are the common practice for 100+ person facilities, plus a restock after any significant incident. Log the audits — a dated checklist on the cabinet door is the simplest defensible record.

Does the First Aid Only 90575 include burn care and eye care?

The listing describes the fill only as ANSI B+, without an itemized manifest, so verify shelf contents on arrival against the Z308.1 checklist. Dedicated burn dressings from the burn care collection are the standard supplement where hot-work or kitchen hazards exist.

Is the First Aid Only 90575 worth it over building your own station?

Building your own from a bare cabinet plus refills can undercut the price, but you own the compliance mapping and the restock list. The 90575's value is arriving as a stated B+ 100-150 person station — one purchase order, one documented basis. Start with the best first aid cabinets ranked guide if you are still weighing the field.
