Urgent First Aid ANSI Class B Refill Kit, 50 Person, 208 Pieces Review (2026)
Is the Urgent First Aid ANSI Class B Refill Kit the right restock for a 50-person, high-risk workplace?
Short answer: Yes — if your kit or cabinet carries a Class B rating and serves up to 50 people, this 208-piece refill is the single-order restock that keeps it at a full ANSI Z308.1-2021 Class B fill. It is the pack we recommend for manufacturing floors, warehouses, and construction offices. If your station is a smaller 25-person Class A box, the cheaper Urgent First Aid Class A Refill Kit, 25 Person is the right-sized buy; if you need an OTC-medication reload for a big cabinet, look at the UniShield ANSI Class B First Aid Refill with Medications.
Class B stations fail quietly. A 50-person cabinet on a production floor gets raided week after week, and by the time anyone audits it, the fill is closer to Class A minus — while the label on the door still promises Class B. The Urgent First Aid ANSI Class B Refill Kit, 50 Person, 208 Pieces (model URG-3685) is the direct fix: one 208-piece order that returns the station to a full Class B fill. This review places it against the other packs in the First Aid Kit Refills collection and maps which kits and cabinets in the First Aid Kits collection it restocks.
Editorial verdict: 4.5/5. The Urgent First Aid Class B Refill packs a 208-piece, 50-person ANSI Class B reload into one $49.95 order — the most efficient way we stock to keep a high-risk-site cabinet at full fill without replacing hardware that isn't broken.

Pros
- 208 pieces sized to return a 50-person Class B station to full fill in one order
- Class B assortment matches high-risk sites — the fill OSHA-driven programs actually need on industrial floors
- Restocks any brand of 50-person Class B kit or cabinet, not just Urgent First Aid containers
- Carries a real model number (URG-3685) — easier for procurement and reorder records
- Half the cost per restock cycle of replacing a mid-size cabinet
Cons
- Overkill — and over-budget — for a 10-25 person office running Class A
- Bulk pack: loading a 3-shelf cabinet takes longer than injury-type-organized refills
- Not a medication-focused reload; cabinets with big OTC sections may still need the UniShield pack
- No trauma components — tourniquets and hemostatics live in a different refill class entirely
Who the Urgent First Aid Class B Refill is for
- Safety managers on high-risk sites — manufacturing, warehousing, fabrication — restocking Class B stations from the Workplace First Aid Kits collection.
- Facilities teams with wall cabinets from the First Aid Cabinets and Stations collection serving up to 50 employees.
- Construction offices running a Class B wall unit like the Ever Ready First Aid ANSI Class B Wall-Mountable Kit under OSHA 1926.50 expectations.
- Anyone whose Class B cabinet has drifted to a half-empty fill and needs to get back to the rating on its label.
What the Urgent First Aid Class B Refill does well
A true Class B reload, not a padded Class A
ANSI Z308.1-2021 defines Class B as the larger assortment in greater quantities for high-risk and higher-population workplaces. This pack's 208 pieces are built to that definition for a 50-person station — roughly two and a half times the piece count of its 78-piece Class A sibling. Our OSHA first aid kit requirements explained reference covers what separates the two classes and why the distinction matters at inspection time.
One SKU restocks the whole station
Auditing a raided 50-person cabinet against the Class B minimum list, then sourcing each shortfall item, is exactly the kind of task that slips a quarter. Ordering URG-3685 collapses it into one line item. That reliability is the argument for brand-name refills over piecemeal restocking from the Bandages and Wound Care collection — the singles shelf is for between-cycle top-ups, not full reloads.
Brand-agnostic fit
The fill is standardized, so the pack restocks 50-person Class B containers across brands: the Ever Ready Class B wall-mount kit, the MFASCO ANSI Class B 3-Shelf First Aid Cabinet, or the UniShield 4-Shelf Metal First Aid Cabinet, ANSI Class B. If the container is rated Class B around the 50-person mark, this is its restock.
The procurement-friendly option
Unlike several import refills, this pack carries a manufacturer model number — URG-3685 — which makes purchase orders, reorder templates, and stockroom records cleaner. Small thing, real advantage for programs that buy on paper trails.
Where the Urgent First Aid Class B Refill falls short
It is the wrong size for small offices
A 10-25 person office running a Class A box does not need 208 pieces of Class B fill; it needs the $24.95 Class A 25-person refill. Buying up a class "to be safe" mostly buys shelf clutter — match the refill to the container's rating, per our first aid kit buyer's guide.
Bulk loading takes time in multi-shelf cabinets
Like its Class A sibling, the pack arrives as bulk components rather than injury-type modules. Loading a 4-shelf cabinet from bulk stock takes noticeably longer than loading from an organized pack like the MFASCO Class A refill (Class A only, unfortunately for cabinet owners).
Medication-heavy cabinets may want the UniShield instead
Restaurant and industrial cabinets with large OTC medication sections are better matched by the UniShield Class B refill with medications — a $169.95 pack explicitly built around a medication-inclusive cabinet reload. Read the head-to-head in our UniShield Class B refill review.
Urgent First Aid Class B Refill vs the competitive set
| Refill | Class | Sized for | Price | Amazon |
|---|---|---|---|---|
| Urgent First Aid Class B Refill, 50 Person (this review) | B | 50 person | $49.95 | Check price |
| UniShield Class B Refill with Medications | B | 3-4 shelf cabinet | $169.95 | Check price |
| Urgent First Aid Class A Refill, 25 Person | A | 25 person | $24.95 | Check price |
| MFASCO Class A Refill Pack | A | Class A kits | $43.99 | Check price |
Read across the set: this pack is the only straight Class B refill at a mid-market price on our shelf. The UniShield is the premium cabinet reload, the Class A sibling is the small-office pick, and the MFASCO pack wins on organization for Class A cabinets.
Urgent First Aid Class B vs Class A: the in-brand decision
| Spec | Class B Refill (URG-3685) | Class A Refill |
|---|---|---|
| ANSI Z308.1-2021 fill | Class B | Class A |
| Piece count | 208 | 78 |
| Crew size | 50 person | 25 person |
| Risk profile | High-risk / industrial | Common injuries |
| Typical price | $49.95 | $24.95 |
- Buy the Class B refill if the station's label says Class B, the site is industrial or high-risk, or headcount runs toward 50 — the container's rating, not optimism, decides.
- Buy the Class A refill if you are restocking a 25-person office, retail, or light-duty box.

Which kits and cabinets this refill restocks
On our shelves, the natural matches are the Class B stations: the Ever Ready First Aid Class B wall-mount kit, the MFASCO Class B 3-shelf cabinet, the UniShield 4-shelf metal cabinet, and the B+ rated EVERLIT CARE 203SFAK100 3-shelf cabinet — for the larger B+ and 100-person units like the First Aid Only 90575, plan on this pack as the core reload plus supplemental quantities.

Category context: why Class B stations drift, and what refills fix
OSHA 29 CFR 1910.151 (and 1926.50 for construction) requires adequate first aid supplies to be readily available; ANSI Z308.1-2021 supplies the fill lists inspectors and insurers actually reference. High-risk sites consume supplies fastest precisely because they are high-risk — which is why Class B stations drift out of compliance faster than the office box ever will. A standing reorder of this refill, plus between-cycle singles from the wound care shelf and Burn Care collection, is the boring, effective answer. For program-level planning — how many stations, what class, where — start at the which first aid kit do you need guide.
Total cost of ownership
A Class B cabinet is a decade-plus container with a consumable fill. On a busy 50-person floor, expect one to two full $49.95 reloads per year plus singles — call it $1-2 per employee per year to keep the station at its rated fill. Compare that with cycling whole $138-$240 cabinets like the EVERLIT CARE 3-shelf or UniShield 4-shelf restaurant cabinet, and the refill program pays for itself in the first year.
Final verdict: 4.5/5
The Urgent First Aid ANSI Class B Refill Kit is the workhorse restock for 50-person, high-risk stations: correctly classed, correctly sized, sanely priced, and traceable by model number. Buy this to keep Class B kits and cabinets at their rated fill. Buy the Class A 25-person refill for small offices, or the UniShield medication-inclusive refill when a large cabinet's OTC section also needs a reload.

Urgent First Aid Class B Refill — FAQ
What does ANSI Class B mean on a first aid refill?
Class B is the larger of the two ANSI Z308.1-2021 fill classes — more item types in greater quantities, designed for high-risk or higher-population workplaces such as manufacturing, warehousing, and construction. Class A is the lighter fill for common workplace injuries. The class is printed on your kit or cabinet's label; the refill must match it. Full decode in our OSHA first aid kit requirements reference.
Which cabinets does the Urgent First Aid Class B Refill restock?
Any 50-person-class Class B kit or cabinet regardless of brand — on our shelf that includes the Ever Ready Class B wall-mount kit, MFASCO Class B 3-shelf cabinet, and UniShield 4-shelf metal cabinet.
Is 208 pieces enough for a 100-person site?
Not on its own. The pack is sized for 50-person stations; a 100-person program should run multiple stations (each with its own refill) or step up cabinet capacity — see 100-person options like the First Aid Only 90575 3-shelf B+ cabinet in our cabinets guide.
Can I restock a Class B cabinet with a Class A refill to save money?
No. A Class B container refilled to Class A levels no longer delivers the fill its label promises, which is exactly what an inspector or insurer will check. Restock to the class on the label — the $25 saved is not worth the finding.
Urgent First Aid Class B Refill vs UniShield Class B Refill with Medications — which to buy?
This pack is the standard Class B reload at $49.95. The UniShield pack at $169.95 is built for full 3-4 shelf cabinet reloads including OTC medications. If your cabinet has a big meds section, buy the UniShield; otherwise this pack does the job for less — comparison in our UniShield review.
Does this refill include OTC medications?
It is built as a standard Class B supply reload rather than a medication-centric pack. Programs that dispense OTC meds in volume typically add them separately or run the medication-inclusive UniShield refill.
How often should a Class B station be refilled?
Inspect monthly on high-risk floors — Class B stations drain fast. Reload whenever any category drops below the ANSI minimums, and sweep dated items at least annually. Busy 50-person floors commonly run one to two full refills per year.
Does the Urgent First Aid Class B Refill meet OSHA construction requirements?
OSHA 1926.50 requires first aid supplies on construction sites; ANSI Z308.1 Class B is the fill class generally matched to that risk level. Keeping a Class B station at full fill with this pack is the standard compliance pattern — site-specific requirements belong to your competent person. Background in the requirements reference.
What is the model number for reordering this refill?
URG-3685. Put it on the standing purchase order with a quarterly inspection trigger and the station effectively maintains itself.
Urgent First Aid Class B vs Class A refill — is the Class B just a bigger Class A?
No — Class B is a different fill definition, not merely more of the same. It adds quantity and breadth to match higher-risk exposure. The 78-piece Class A pack serves 25-person common-injury environments; this 208-piece pack serves 50-person high-risk ones — full head-to-head in our Class A refill review.
Will this refill restock a trauma kit or IFAK?
No. Tourniquets, hemostatic gauze, and chest seals belong to trauma restocks like the RHINO RESCUE IFAK Refill Kit with CAT Gen-7 — see the trauma kits collection. Class B refills cover the ANSI workplace fill only.
Do refill supplies expire, and which go first?
Antiseptics, ointments, and OTC items carry expiration dates and lapse first; dressings and bandages last longer if sealed. Run an annual dated-item sweep even in stations that see little use — expired stock fails audits as surely as missing stock.
Can I split one Class B refill across two smaller kits?
You can physically, but neither kit ends up at a verifiable full fill, which defeats the audit trail. Cleaner: give each station its own class- and size-matched refill from the refills collection.
What between-refill top-ups should I keep on hand?
The fastest-moving categories: adhesive bandages such as Band-Aid Flexible Fabric bandages, non-stick pads like Med Pride 60733 sterile non-stick pads, and burn dressings from the burn care shelf.
Where should Class B stations be placed on a 50-person site?
Close to the hazards and reachable within minutes — production floor, loading dock, maintenance shop — rather than one central office cabinet. Station-count and placement planning is covered in the which first aid kit do you need guide and the best workplace first aid kits guide.
