MFASCO ANSI Class A First Aid Kit Refill — 116 Pieces, Z308.1-2021

MFASCO ANSI Class A First Aid Kit Refill overview

The MFASCO ANSI Class A First Aid Kit Refill is a 116-piece refill pack that restocks a workplace first-aid kit to the current ANSI/ISEA Z308.1-2021 Class A contents standard and supports OSHA 1910.151(b). It comes in a 4-compartment clear sectioned bag so supplies stay organized and visible, and it's sized to fit medium kits of at least 10 x 9 x 3 in. See our best workplace first aid kits guide and the first aid kits collection.

Two things to be clear about. First, it's a refill, not a complete kit — contents only, no case — so it's for restocking or upgrading an existing medium kit, not replacing the whole thing, and medicines are not included. Second, on compliance: it meets the ANSI Z308.1-2021 Class A standard and supports OSHA's first-aid requirement, but OSHA doesn't certify products, so your actual compliance depends on your workplace's risk level and program. Class A is the baseline for lower-risk sites; higher-risk workplaces step up to Class B — see the MFASCO Class B cabinet. Keep the kit in a proper first-aid cabinet, and pair it with an eyewash station where there's a splash risk.

Where the MFASCO ANSI Class A First Aid Kit Refill fits

It's the one-pack restock for offices, small shops, retail, warehouses and other lower-risk workplaces that keep an ANSI Class A kit and need to bring it back to full, current contents — or upgrade an older kit to the 2021 standard. The sectioned bag makes it fast to load and fast to use. Where it's not the answer is a higher-risk site that needs Class B contents, a workplace with no existing kit or case (you'd want a complete kit first), or a substitute for training and professional care. Keep your broader safety program stocked too — our first aid kit and spill kit guides help, and see OSHA 1910.132 PPE requirements for the wider picture.

Frequently asked questions

What is a Class A refill, and what does ANSI Z308.1 mean?

ANSI/ISEA Z308.1 is the consensus standard that sets the minimum contents for a workplace first-aid kit. Class A is the baseline list, aimed at lower-risk workplaces. This refill brings a kit's contents up to the current Z308.1-2021 Class A requirement in one pack.

Is this a complete kit or just the contents?

Just the contents — it's a refill, not a complete kit with a case. It's a 116-piece pack in a 4-compartment sectioned bag, sized to fit a medium kit of at least 10 x 9 x 3 inches, so you restock or upgrade an existing case rather than buying a whole new kit.

Does using it make me OSHA compliant?

It meets the ANSI/ISEA Z308.1-2021 Class A contents standard and supports OSHA 1910.151(b), which requires adequate first-aid supplies. But OSHA doesn't certify individual products, and your actual compliance depends on your workplace's risk level, the number of people, and your overall program — Class A is the baseline, and some sites need Class B.

How many pieces are included, and what kind of supplies?

116 pieces of first-aid supplies — bandages, gauze, tape, antiseptic wipes and the other items on the Z308.1 Class A list — organized in a 4-compartment clear bag so you can find what you need without everything spilling out.

Are medicines included?

No — medicines are not included. Class A refill contents are supplies for treating wounds and minor injuries, not oral or topical drugs, which many workplaces handle separately for policy and liability reasons.

Do the supplies expire?

Yes — first-aid items carry expiration dates, and some (like antiseptics and ointments) degrade over time. Check the dates when you restock, rotate anything expired, and inspect the kit on a schedule so it's ready when it's needed.

Class A or Class B — which do I need?

Class A is the baseline for lower-risk workplaces. Class B has more of each item and adds supplies for higher-risk environments. If your hazard assessment or site type calls for Class B, step up to a Class B kit or refill rather than relying on Class A.

Will it fit my existing first-aid kit?

It's sized for medium kits — roughly 10 x 9 x 3 inches or larger. Check your case's interior dimensions before ordering; a refill that doesn't fit the case won't organize or close properly.

What's the point of the 4-compartment bag?

The clear, sectioned bag keeps categories of supplies separated and visible, so during an emergency you can grab the right item quickly instead of digging through a jumble — and everything doesn't fall out when you open it.

How often should I restock?

Restock immediately after any use, and replace expired items as you find them — a first-aid kit is only useful if it's actually stocked, so inspect it regularly rather than assuming it's full.

Do I still need first-aid training?

Yes. Supplies don't replace trained responders — pair a stocked kit with people trained in first aid and CPR, and remember first aid is initial care, not a substitute for professional medical treatment or calling emergency services for a serious injury.

Are the bandages good quality?

The pack uses fabric bandages designed to stay on even in damp conditions, which hold up better than basic plastic strips on active, sweaty or wet work.

Reviewed by Steven Eaton, WC Safety. Specifications reflect MFASCO's published data for the Class A refill; it meets the ANSI/ISEA Z308.1-2021 Class A contents standard and supports OSHA 1910.151(b), but OSHA does not certify products, and it is a refill (no case) with no medicines and dated supplies — match the class to your workplace's risk and keep the kit inspected and rotated.
