OSHA Compliance Kits — Workplace First Aid Cabinets

Which OSHA compliance kits keep your workplace covered?

Short answer: the OSHA compliance kits on this shelf are all workplace first-aid kits, cabinets and refills — nineteen listings from nine vendors — and the split that matters is ANSI/ISEA Z308.1 class: Class A covers common workplace injuries, Class B adds quantity and range for higher-risk sites. The class logic is unpacked in Class A vs Class B, ranked picks in best workplace first aid kits and best first aid cabinets.

Stated ANSI Z308.1 classes on this shelf

That last row is the honest print: four listings (including both 100-person kits) state an OSHA person-count but no ANSI class, and one vendor label ("A+") sits outside the two-tier framework entirely. The two compliance tiers describe fourteen of nineteen listings — not the whole shelf.

OSHA Workplace First Aid Kits — First Aid Kits Meeting OSHA 1910.151 Requirements

OSHA workplace first aid kits are designed and stocked to meet the requirements of OSHA 29 CFR 1910.151 and the ANSI/ISEA Z308.1 standard for workplace first aid supplies, providing employers with confidence that their first aid program meets regulatory compliance requirements. OSHA 1910.151(b) requires that "adequate first aid supplies shall be readily available" and that a person adequately trained in first aid be available when medical facilities are not near the workplace. The phrase "adequate first aid supplies" has been interpreted by OSHA to mean supplies sufficient to treat the types of injuries likely to occur in that specific workplace — making ANSI Z308.1 compliance the practical benchmark for demonstrating adequacy.

ANSI Z308.1 Class A and Class B workplace kits represent the two compliance tiers. Class A kits are designed for low-hazard workplaces — offices, light manufacturing, retail — where the injury profile primarily involves minor cuts, abrasions, eye irritation, and minor burns. Class B kits are designed for higher-hazard environments — construction, heavy manufacturing, chemical handling — where more serious injuries are more likely and more comprehensive supplies are needed to manage them pending professional medical response. The ANSI standard specifies minimum unit quantities for each supply item in each class, allowing purchasers to verify compliance by comparing kit contents against the standard's minimum quantity tables.

OSHA record-keeping related to first aid treatment is a separate compliance requirement from kit stocking. OSHA 29 CFR 1904 requires recording of all injuries that require medical treatment beyond first aid — meaning that tracking what first aid treatments have been administered from workplace kits serves both restocking and injury record purposes. Maintaining a first aid log in the kit cabinet that records date, name, injury type, and treatment provided creates documentation that supports both OSHA 300 Log injury recording and kit restocking decisions. Injuries requiring only first aid (without stitches, prescription medication, or restricted duty) are generally not OSHA 300-recordable, making accurate first aid treatment documentation important for record-keeping accuracy.

First aid station placement requirements under OSHA require that first aid supplies be "readily available" to employees — OSHA has indicated that kits should be accessible within reasonable travel time, and best practice programs position first aid kits within 3-minute walking distance of any work area. Large facilities with multiple work zones should maintain multiple first aid stations, ensuring that kits are accessible without crossing multiple departments or navigating significant distances in an injury scenario where the affected person may need to apply self-treatment while waiting for assistance.

Our OSHA workplace first aid kit collection covers ANSI Class A and Class B kits in 10-person through 100-person sizes, in wall-mount, portable, and vehicle configurations, with documentation forms and restocking supply packs to maintain ongoing compliance after kit use.

Frequently Asked Questions

Why do some kits state no ANSI class at all?

Person-count kits (50-person, 100-person) are sold against OSHA’s general adequacy duty rather than the Z308.1 class system. They can be perfectly serviceable — but you, not the label, must verify contents against your hazard assessment.

Is "ANSI A+" a real class?

No — Z308.1 defines Class A and Class B. "A+" is a vendor label meaning above-Class-A contents; treat it as Class A compliant with extras, verified against the contents list.

Cabinet or kit — which format fits a fixed workplace?

Wall-mounted cabinets for fixed sites — visible, restockable shelf by shelf, and auditable at a glance. Portable kits belong in vehicles and on mobile crews; several listings here are refill packs sized to keep a cabinet compliant without rebuying the metal.

How often should a workplace kit be checked?

Monthly is the defensible cadence — restock anything used, replace expired items, and log the check. An out-of-date kit fails the OSHA adequacy duty just as surely as a missing one.

What should OSHA workplace first-aid kits contain?

For a compliant workplace kit, stock bandages, gauze, antiseptic, gloves, tape, scissors, and trauma items, sized to your headcount the way ANSI/ISEA Z308.1 specifies.

What does OSHA require for workplace first aid?

The rule is OSHA 1910.151: keep adequate first-aid supplies readily available. An ANSI/ISEA Z308.1 Class A or Class B kit is the usual yardstick for compliance.

What is the difference between Class A and Class B first-aid kits?

Class A is the baseline for everyday workplace injuries; Class B steps up the count and assortment of supplies to suit high-risk operations or larger workplaces.

How many kits or what size do I need?

Match it to your worker count and the travel time to medical care. Big or dispersed facilities need multiple kits, positioned wherever injuries tend to occur.

How often should I check and restock OSHA workplace first-aid kits?

Schedule routine checks, restock used items without delay, and verify expiration dates on drugs and sterile goods so the kit stays mission-ready.

Where should I keep OSHA workplace first-aid kits?

Mount it where staff can grab it fast and everyone knows the location, typically near exits at work, by a home door, or inside a vehicle for the road.

Do the supplies in OSHA workplace first-aid kits expire?

Indeed they do. Sterile dressings, ointments, and medications are dated, so cycle older stock out and refill with fresh contents before anything lapses.

Should I customize OSHA workplace first-aid kits?

Customizing is wise. Layer in prescribed medications, emergency contact details, and job-specific extras that a generic kit was never meant to include.

Are OSHA workplace first-aid kits suitable for vehicles?

They travel fine when compact and sealed. Store it within reach in the cab and keep medications out of the temperature swings a trunk can deliver.

Do OSHA workplace first-aid kits include instructions?

Many come with a basic first-aid booklet. Backing those supplies with up-to-date first-aid and CPR training is what makes the kit effective in a crisis.

Our methodology

We pulled all nineteen live records, tabulated only the ANSI classes their own titles state, and flagged the four kits that state none rather than rounding the shelf up to blanket compliance. First-aid duties come from OSHA 29 CFR 1910.151, with kit classes defined by ANSI/ISEA Z308.1 and emergency-care context from NIOSH. We do not test kits and hold no medical or safety certification.
