MFASCO First Aid Kit Refill Pack, 417 pcs, ANSI 2021 Class B Review (2026)
Is the MFASCO 417-Piece ANSI Class B Refill the right restock for a Class B-rated cabinet?
Short answer: Yes — for any station labeled ANSI/ISEA Z308.1-2021 Class B, this 417-piece MFASCO refill is a straightforward, brand-matched way to restore it, and it pairs directly with the MFASCO ANSI Class B 3-Shelf First Aid Cabinet it's sized for. If your program also needs OTC medications in the reload, the $169.95 UniShield ANSI Class B Refill with Medications is the closest medication-inclusive alternative.
Class B stations exist because Class A fills run out fast on high-risk or high-headcount floors. The MFASCO First Aid Kit Refill Pack, 417 pcs, ANSI 2021 Class B is built to restore that larger fill in one order — 417 pieces, stocked explicitly to the 2021 edition of ANSI/ISEA Z308.1 Class B. This review checks that claim against price, against MFASCO's own Class A refill one tier down, and against the rest of the Class B field in the First Aid Kit Refills collection.
It sits inside the broader First Aid Kits collection, and the class-selection question it answers — Class A or Class B — is covered in full in our Which First Aid Kit Do You Need? buyer's guide.
Editorial verdict: 4.4/5. The MFASCO 417-Piece ANSI Class B Refill is the direct, brand-matched way to restock a Class B-rated cabinet — a large single-order fill, explicitly tied to the 2021 edition of Z308.1 Class B, at a mid-market $128.50. It skips OTC medications and asks for a bigger single order than smaller Class B packs, but for a station already labeled Class B it is the cleanest restock we stock.

Pros
- Explicitly stocked to the current ANSI/ISEA Z308.1-2021 Class B standard, named on the listing
- 417 pieces — one of the larger single-order Class B reloads we carry
- Purpose-matched to the MFASCO ANSI Class B 3-Shelf First Aid Cabinet for a same-brand program
- Brand-agnostic beyond MFASCO hardware — restocks any Class B-rated container
- Mid-market price against medication-inclusive Class B competitors
Cons
- No OTC medications included — the UniShield Class B pack covers that gap for $41.45 more
- $128.50 is a large single order compared to the $49.95 Urgent First Aid Class B pack for smaller stations
- No published person-count rating on the listing; verify delivered quantities against your cabinet's rated fill
- The matched-brand advantage is smaller if you don't already run MFASCO cabinet hardware
Who the MFASCO 417-Piece Class B Refill is for
- MFASCO Class B cabinet owners running the MFASCO ANSI Class B 3-Shelf First Aid Cabinet who need the matched-brand reload.
- High-risk or higher-headcount facilities in the Workplace First Aid Kits collection whose Class A stock no longer covers their injury volume.
- Programs upgrading from Class A — sites that started with the MFASCO ANSI Class A First Aid Kit Refill Pack and have outgrown it.
- Multi-shelf cabinet operators who want one large-format order rather than several small refill packs from the First Aid Kit Refills collection.
What the MFASCO 417-Piece Class B Refill does well
Explicitly named 2021-edition Class B compliance
Not every refill on the market names the edition year of the standard it's built to. This pack's title states ANSI/ISEA Z308.1-2021 Class B directly, which is the strongest way a listing can anchor a class claim for procurement records. Our OSHA First Aid Kit Requirements reference decodes what the 2021 edition changed and why the edition year matters for audits.
417 pieces is a genuinely large single-order fill
At 417 pieces, this is one of the bigger reloads we stock in the Class B tier — well above the 208-piece Urgent First Aid ANSI Class B 50-Person Refill. For a multi-shelf cabinet that sees regular traffic, ordering once at 417 pieces beats reordering a smaller pack twice.
Purpose-matched to MFASCO's own Class B cabinet
The MFASCO ANSI Class B 3-Shelf First Aid Cabinet carries the same Class B rating, so this refill is the obvious reorder for anyone already running that cabinet — no cross-brand guesswork about whether the fill actually matches the container's rated capacity.
Brand-agnostic across any Class B container
Like any class-built refill, it isn't locked to MFASCO hardware. It restocks any container labeled ANSI Z308.1-2021 Class B, including the MFASCO 4-Shelf Commercial First Aid Cabinet as a partial reload across its extra shelf capacity.
Where the MFASCO 417-Piece Class B Refill falls short
No medications included
The pack does not include OTC medications. Programs that need ibuprofen, antihistamines, or similar OTC items in the reload should compare against the UniShield ANSI Class B Refill with Medications, reviewed separately in our UniShield Class B refill review. Per FDA OTC labeling guidance, this page identifies products only — it does not offer dosing or medical advice.
A big order isn't right for every station
At $128.50 for 417 pieces, this is a large single purchase. A single small Class B box restocked once a year may not need that volume; the $49.95 Urgent First Aid Class B 50-Person Refill covers a smaller station for less upfront cash.
No published person-count rating
Unlike the Urgent First Aid pack, which states its 50-person target directly, this listing doesn't publish a person-count rating alongside the piece count. Verify delivered quantities against your cabinet's labeled fill before assuming full coverage for your headcount.
MFASCO 417-Piece Class B Refill vs the competitive set
| Refill | Class | Pieces | Medications | Price | Amazon |
|---|---|---|---|---|---|
| MFASCO 417-Piece ANSI Class B Refill (this review) | B | 417 | No | $128.50 | Check price |
| UniShield ANSI Class B Refill with Medications | B | Not published | Yes | $169.95 | Check price |
| Urgent First Aid ANSI Class B Refill, 50 Person | B | 208 | No | $49.95 | Check price |
The short read: buy the MFASCO 417-piece pack for the largest single-order Class B reload matched to MFASCO hardware, the UniShield pack if OTC medications need to be in the box, and the Urgent First Aid pack for a smaller Class B station on a tighter budget.
MFASCO 417-Piece Refill vs MFASCO's own refill lineup: which to buy
| MFASCO refill | ANSI class | Pieces | Price | Amazon |
|---|---|---|---|---|
| MFASCO 417-Piece ANSI Class B Refill (this review) | B | 417 | $128.50 | Check price |
| MFASCO ANSI Class A Refill Pack | A | Not published | $43.99 | Check price |
| MFASCO Workplace 4-Shelf Refill, 519 Piece | Not stated | 519 | $170.00 | Check price |
- Buy the 417-piece Class B refill if your cabinet is labeled ANSI Z308.1-2021 Class B and you don't need OTC medications in the box.
- Buy the MFASCO Class A Refill Pack if your station is Class A-rated for common workplace injuries — see our MFASCO Class A refill review.
- Buy the MFASCO Workplace 4-Shelf Refill if you're loading a 4-shelf wall cabinet and want the largest raw piece count MFASCO sells — note its listing doesn't state an ANSI class, so confirm it against your cabinet's own rating before ordering.

Which kits and cabinets this refill restocks
The direct match on our shelves is the MFASCO ANSI Class B 3-Shelf First Aid Cabinet — same brand, same 2021-edition Class B rating. It also works as a partial reload on the larger MFASCO 4-Shelf Commercial First Aid Cabinet, and generically for any third-party cabinet in our First Aid Cabinets collection labeled Class B. It is not a fit for the compact MFASCO Vehicle First Aid Kit Metal Case — a 417-piece fill simply doesn't fit a vehicle-sized case. If you're still choosing a container, our best first aid cabinets guide ranks the field by headcount and risk level.
| Kit / cabinet | Rated for | Fit note |
|---|---|---|
| MFASCO Class B 3-Shelf Cabinet | Class B | Purpose-built match — same class, same brand |
| MFASCO 4-Shelf Commercial Cabinet | Type I & II | Larger station; use as a partial reload and verify against its rated fill |
| MFASCO Vehicle First Aid Kit | Vehicle DOT/ANSI/OSHA | Not compatible — case too small for a 417-piece fill |

Category context: Class B refills inside a first aid program
Class B exists in ANSI/ISEA Z308.1-2021 specifically for higher-risk or higher-headcount environments where Class A's smaller fill runs out too fast. OSHA 29 CFR 1910.151 requires supplies to be adequate and readily available, and points to the ANSI standard as the reference for what "adequate" means; the full mechanics of that relationship are in our OSHA first aid kit requirements reference. Choosing between Class A and Class B in the first place — and deciding which of your stations needs the upgrade — is the subject of our Which First Aid Kit Do You Need? buyer's guide.
Total cost of ownership
At $128.50, this refill costs roughly 72% of the $179.95 MFASCO Class B 3-Shelf Cabinet it restocks — refilling the same hardware annually is dramatically cheaper than replacing it. Against the $49.95 Urgent First Aid Class B pack, the per-piece cost lands close (roughly $0.31/piece here versus roughly $0.24/piece there), so the decision comes down to order size, not efficiency: one large 417-piece order versus smaller, more frequent 208-piece reorders. Programs adding a dedicated burn layer can supplement separately with the MFASCO First Aid Kit Refill Burn Care Refill Pack from the Burn Care collection rather than paying for burn supplies twice.
Final verdict: 4.4/5
The MFASCO 417-Piece ANSI Class B Refill is the recommendation for any station explicitly labeled ANSI/ISEA Z308.1-2021 Class B, and the natural reorder for anyone running the MFASCO Class B 3-Shelf Cabinet. Buy this for a large single-order Class B restock without medications. Buy the UniShield Class B refill if OTC medications must be in the box, or the Urgent First Aid Class B pack for a smaller station on a tighter budget.

MFASCO 417-Piece ANSI Class B Refill — FAQ
Is the MFASCO 417-Piece Refill ANSI/ISEA Z308.1-2021 Class B compliant?
Yes — the listing states ANSI/ISEA Z308.1-2021 Class B directly, naming the current edition of the standard. That makes it a compliant fill for any station labeled Class B under the 2021 edition. See our OSHA first aid kit requirements reference for how the edition year factors into audits.
How many pieces are in the MFASCO Class B refill pack?
417 pieces. That is roughly double the 208-piece Urgent First Aid Class B 50-Person Refill, though the two packs aren't necessarily interchangeable item-for-item — verify categories against your cabinet's rated fill.
Does the MFASCO 417-piece refill include medications?
No. It is a supplies-only Class B fill. Programs that need OTC medications in the reload should compare the UniShield ANSI Class B Refill with Medications, covered in our UniShield Class B review. This page identifies products only and does not offer dosing guidance.
MFASCO 417-Piece Class B Refill vs MFASCO Class A Refill Pack — which should I buy?
Match the class to your cabinet's label, not the other way around. The MFASCO Class A Refill Pack restocks common-injury Class A stations at $43.99; this 417-piece pack restocks higher-risk Class B stations at $128.50. Full detail in our MFASCO Class A refill review.
MFASCO 417-Piece refill vs MFASCO Workplace 4-Shelf 519-Piece refill — which is bigger?
The MFASCO Workplace 4-Shelf Refill has more raw pieces (519 vs 417) at a similar price ($170.00 vs $128.50), but its listing does not state an ANSI class the way this 417-piece pack states Class B. If class compliance documentation matters, this pack is the safer paper trail.
Does this refill work in non-MFASCO Class B cabinets?
Yes. Class B fills are standardized by ANSI/ISEA Z308.1-2021, so this refill restocks any container rated Class B, not only MFASCO's own hardware.
MFASCO 417-Piece Class B refill vs UniShield Class B refill with medications — which should I buy?
Same class, different scope. The UniShield pack costs $41.45 more but adds OTC medications; this MFASCO pack skips medications and pairs with MFASCO's own cabinet line. Choose UniShield if the reload must include medications, MFASCO if it doesn't and brand-matching your cabinet matters.
MFASCO 417-Piece Class B refill vs Urgent First Aid Class B 50-Person refill — which is the better value?
The Urgent First Aid pack is cheaper upfront ($49.95) with a published 50-person rating and 208 pieces; this MFASCO pack costs more ($128.50) but delivers roughly double the piece count in one order. Smaller single station: Urgent. Larger station or fewer reorders preferred: MFASCO — see our Urgent First Aid Class B review.
What cabinet pairs best with this refill?
The MFASCO ANSI Class B 3-Shelf First Aid Cabinet is the direct in-catalog match — same brand, same class. Our best first aid cabinets guide ranks the wider field.
Does this refill satisfy OSHA first aid requirements?
OSHA 29 CFR 1910.151 requires adequate, readily available supplies and points to ANSI Z308.1 as the reference fill standard. Maintaining a Class B station with a Class B refill like this one is the standard compliance pattern for higher-risk workplaces — see our requirements reference for the full explanation.
How many people does the 417-piece Class B refill cover?
The listing does not publish a person-count rating. Treat it as a 417-piece Class B assortment reload and check delivered category quantities against your cabinet's own rated headcount before assuming full coverage.
Can I use this refill to top up a Class A kit?
You can pull individual items from it, but it is not the efficient choice for a Class A-only station — buy the lower-cost MFASCO Class A Refill Pack instead and reserve this Class B pack for Class B-rated cabinets.
Does the pack include burn care supplies, or do I need a separate burn refill?
General Class B fills include limited burn-care basics but not a dedicated burn layer. High-exposure sites should add the MFASCO First Aid Kit Refill Burn Care Refill Pack from the Burn Care collection alongside this general reload.
How often should I run a full Class B refill versus single-item top-ups?
A common cadence: quarterly visual inspections, single-item top-ups whenever one category runs low, and a full refill annually or whenever several categories drop below Class B minimums at once. A full refill also resets the expiration clock on dated items.
Which items in a Class B fill expire first?
Antiseptics, ointments, and any OTC items in a comparable medicated pack typically carry the shortest dating; sterile dressings hold longer if the packaging stays sealed. Log the earliest expiration date when you load the cabinet and schedule the next full refill against it.
Is this refill a good match for high-risk industrial sites?
Yes — that's precisely what Class B is written for. Pair it with the MFASCO Class B 3-Shelf Cabinet for a matched high-risk station, and add trauma or eyewash coverage separately if your hazard assessment calls for it.
Can I use this refill in a 4-shelf commercial cabinet instead of a 3-shelf one?
Yes, as a partial reload — the MFASCO 4-Shelf Commercial Cabinet is rated Type I & II with more capacity than this refill's 417 pieces fill on its own, so verify against that cabinet's full rated fill and supplement categories that run short.
Where does this refill fit in a multi-station compliance program?
Standardize by class: Class A stations reorder the MFASCO Class A pack, Class B stations reorder this 417-piece pack (or a competing Class B pack), and burn-heavy areas add the burn care refill on top. Our program-planning guide lays out the structure station by station.
