Walk over to the first aid cabinet in your breakroom and open it. If half the burn gel is gone, the bandages are the wrong size, and nobody can remember the last time it was restocked, you are not alone, and you may not be compliant. For employers across any state in the U.S., a half-empty kit is more than an inconvenience. It is an OSHA citation waiting to happen and, far worse, a real risk to the people who work for you.
"On a job site, the first few minutes after an injury decide everything," says Auby Ninemire, Director of Safety at Jensen Builders Ltd., a Fort Dodge, Iowa general contractor and CITY First Aid and Safety Supplies customer. "I do not want my crews wondering whether the kit is stocked. I want to know it is handled so we can focus on getting our people taken care of."
That confidence is exactly what compliance is supposed to buy you, and most businesses are closer to a gap than they think.
What OSHA actually requires
OSHA's medical and first aid standard, 29 CFR 1910.151, requires that adequate first aid supplies be readily available in the workplace. The regulation itself is broad on purpose, but the appendix points employers directly to the ANSI/ISEA Z308.1 standard as the accepted benchmark for what "adequate" means. In practice, that is the standard that inspectors and safety professionals use to judge whether your kit measures up.
The current version, ANSI/ISEA Z308.1-2021, sorts workplace kits into two classes. Class A kits cover the most common workplace injuries: cuts, abrasions, minor burns, and eye injuries. Class B kits include everything in a Class A kit but in larger quantities and with additional items, built for higher-risk environments like construction, manufacturing, and warehousing. If your operation carries a higher chance of serious injury, a basic drugstore kit on the wall does not meet the bar.
The 2021 update also raised the floor on what belongs inside. A foil rescue blanket is now required in both Class A and Class B kits; the required quantities of hand sanitizer went up, and Class B kits now specify the type of tourniquet that must be included. Kits assembled to the older standard are, by definition, out of date.
Why does this matters more in some markets than others
The same standard applies everywhere, but the risks behind it look different depending on where you operate.
In Phoenix and across the Southwest, heat is the headline hazard. Outdoor crews and un-airconditioned warehouses push heat illness to the top of the list, which means your kit and your training need to account for heat emergencies, not just cuts and sprains.
In Minnesota and Iowa, the mix tilts toward agriculture, manufacturing, and construction, along with cold-weather exposure for much of the year. These are classic Class B environments where serious wounds and equipment injuries are a genuine possibility.
In the Chicago and Los Angeles metros, dense industrial, logistics, and warehouse operations mean high headcounts and high traffic through every first aid cabinet. The more people relying on a kit, the faster it empties, and the easier it is for restocking to fall through the cracks.
Wherever you are, the lesson is the same. A compliant kit is not a one-time purchase. It is something that has to be maintained.
The real problem: kits that drift out of compliance
Most businesses do not fail an inspection because they never bought a first aid kit. They fail because the kit slowly fell apart. Supplies get used and never replaced. Products expire. The standard changes, and the kit does not. Six months later, the cabinet that was fully stocked in January is missing the exact items someone needs in an emergency.
This is the quiet gap that catches good employers off guard, and it is the gap a managed service is built to close.
