Which kits does the First Aid Only 90583 restock?

The First Aid Only 90583 is built as the factory refill for First Aid Only's 25-person kit line, starting with the First Aid Only 9302-25M 25-Person Contractor First Aid Kit. It's also a workable generic Class A restock for other brands' 25-person kits, including the ProHeal 10-Person ANSI Class A First Aid Kit paired with a second small kit and small cabinets like the UniShield 3-Shelf Metal First Aid Cabinet, ANSI Class A.

What's NOT compatible: this refill is sized for 25-person kits — it will not fully restock a 50-person kit like the First Aid Only 91248 OSHA-Compliant 50-Person First Aid Kit without ordering two packs.

First Aid Only 90583 vs sibling refills

Price is nearly identical between the First Aid Only 90583 and the Urgent First Aid Class A Refill — the decision comes down to brand match. If your kit is a First Aid Only box, the 90583 is built to that exact fill. If your kit is any other brand, the Urgent First Aid pack is equally compliant. Buyers who restock cabinets with rotating staff should weigh the MFASCO Class A Refill Pack's injury-type sorting against the higher price. See the First Aid Only 90583 review for the full breakdown.

• Choose the First Aid Only 90583 if your kit is a First Aid Only branded 25-person box.
• Choose the Urgent First Aid Class A refill if your kit is a different brand.
• Choose the MFASCO pack if injury-type sorting matters more than a few dollars.

First Aid Only 90583 25-Person Refill — FAQ

Does this refill only work with First Aid Only kits?

It's built as the factory match for First Aid Only's 25-person line, but the fill is ANSI-aligned and works as a generic 25-person Class A restock in other brands' containers too.

What kit does model 90583 restock by default?

It's the standard refill for the First Aid Only 9302-25M 25-Person Contractor First Aid Kit and similar First Aid Only 25-person boxes.

Yes, the fill aligns with ANSI/ISEA Z308.1-2021 Class A minimums for a 25-person kit. Details in our OSHA first aid kit requirements reference.

Will one pack refill a 50-person First Aid Only kit?

No — order two packs for a 50-person kit like the First Aid Only 91248, or use a purpose-built 50-person refill.

First Aid Only 90583 vs Urgent First Aid Class A Refill — which should I buy?

They're priced within a few cents of each other. Buy the 90583 for a First Aid Only branded kit; either works equally well for any other 25-person Class A container. See the Urgent First Aid Class A Refill review for the comparison.

Yes — it restocks a small Class A wall cabinet like the UniShield 3-Shelf Class A Cabinet the same way it restocks a portable kit.

How often should I reorder this refill?

Most 25-person First Aid Only kits need one full refill per year plus occasional single-item top-ups between full reloads.

Does this pack contain any OTC medications?

No — for a Class B reload that includes OTC medications, see the UniShield Class B Refill with Medications.

Is this the right refill for a contractor's truck kit?

Yes, if the truck kit is the First Aid Only 9302-25M or similar 25-person First Aid Only box — it's the exact factory match.

Where can I read a full breakdown before I order?
