ANSI/ISEA Z308.1 Minimum Requirements for Workplace First Aid Kits: what it requires and the equipment it names
ANSI/ISEA Z308.1 is the workplace first aid kit standard that OSHA's 1910.151 Appendix A points to as the example of adequate first aid supplies. It sets the minimum fill for a Class A kit (common injuries) and a Class B kit (larger or higher-risk workplaces), and rates the container as Type I to IV by portability and water resistance. We sell nationwide; ships in 1–2 business days; most orders arrive in 3–7 business days.
The plain answer
ANSI/ISEA Z308.1 is the American National Standard for Minimum Requirements for Workplace First Aid Kits and Supplies. OSHA does not incorporate it as a rule; 29 CFR 1910.151(b) requires adequate first aid supplies to be readily available, and non-mandatory Appendix A says the contents listed in Z308.1 are adequate for small worksites, so a Z308.1 kit is the way most employers show they meet the paragraph.
As the manufacturers' catalogs state it (PIP's first aid catalog lists the 2021 classes and piece counts), the 2021 edition defines two classes by contents: a Class A kit for the most common workplace injuries (16 adhesive bandages, adhesive tape, 10 antibiotic treatments, 10 antiseptics, a breathing barrier, a burn dressing, 10 burn treatments, a cold pack, 2 eye coverings, 1 ounce of eye and skin wash, a first aid guide, 6 hand sanitizers, 2 pairs of exam gloves, a roller bandage, scissors, 2 sterile pads, 2 trauma pads, a triangular bandage, a tourniquet and a foil blanket) and a Class B kit with larger quantities (50 adhesive bandages, 25 antibiotic, 50 antiseptic, 25 burn treatments, 4 ounces of eye wash, 4 pairs of gloves, two roller bandages, a splint, 4 sterile pads, 4 trauma pads, 2 triangular bandages and the tourniquet and blanket) for larger, more complex or higher-risk work environments. Containers are Type I (stationary indoor), Type II (portable indoor), Type III (portable, mountable, water resistant) and Type IV (portable, mountable, waterproof for outdoor and mobile use).
The equipment it names is first aid kits and cabinets of Class A and Class B in Type I to IV containers, the listed supplies as refills, and supplementary items the standard lists for the employer's assessment (such as additional tourniquets, splints and bleeding control kits).
What the rule says
Each entry is condensed from the paragraph cited; the paragraph itself is the rule and the link opens it.
29 CFR 1910.151(b): In the absence of a nearby infirmary, clinic or hospital, trained first aiders and adequate first aid supplies readily available.
29 CFR 1910.151 Appendix A: An example of the minimal contents of a generic first aid kit is described in ANSI Z308.1; the contents are adequate for small worksites; larger or multiple operations may need additional kits, equipment and quantities; employers with unique or changing needs enhance their kits, using the OSHA 300 and 301 logs and advice from the local fire and rescue department or emergency room.
29 CFR 1926.50(d): Construction: first aid supplies easily accessible, in a weatherproof container with individually sealed packages for each type of item, checked before each job and at least weekly, expended items replaced (the Type III and IV containers of the standard are built for this).

Supplementary items the standard lists for the employer's own assessment, which manufacturers sell as add-ons: additional tourniquets, bleeding control kits, splints, cold packs, eye wash, analgesics and burn care, with the OSHA 300 log the suggested guide to what a site needs more of.

ANSI/ISEA Z308.1 Minimum Requirements for Workplace First Aid Kits questions
What is a Class A first aid kit? The Z308.1 kit for the most common workplace injuries, with the minimum fill the standard lists: 16 adhesive bandages, tape, 10 antibiotic and 10 antiseptic applications, a breathing barrier, a burn dressing and 10 burn treatments, a cold pack, 2 eye coverings, 1 ounce of eye wash, a first aid guide, hand sanitizer, 2 pairs of gloves, a roller bandage, scissors, 2 sterile pads, 2 trauma pads, a triangular bandage, and since 2021 a tourniquet and a foil blanket.
Who needs a Class B first aid kit? The standard describes Class B for larger, more complex or higher-risk work environments, such as construction, manufacturing and warehousing with more workers or more serious hazards; it carries larger quantities (50 bandages, 50 antiseptics, 4 ounces of eye wash, 4 pairs of gloves) plus a splint and a 4 inch roller bandage. OSHA's Appendix A leaves the choice to the employer's assessment of the worksite.
What is the difference between a Class A and a Class B first aid kit? Quantity and a few items. Class B roughly triples the bandages, antiseptics and burn treatments, doubles the gloves, cold packs, trauma pads and triangular bandages, raises the eye wash from 1 to 4 ounces, and adds a splint and a 4 inch roller bandage; both include the tourniquet and foil blanket added in 2021.
What is a Class A Type 3 first aid kit? A kit with the Class A minimum fill in a Type III container: portable, mountable and sealed against water for indoor and sheltered outdoor use. Type I is a stationary cabinet, Type II a portable indoor box, and Type IV a waterproof, impact-tested case for vehicles and outdoor jobsites.
Does OSHA require an ANSI first aid kit? 1910.151(b) requires adequate first aid supplies and does not name a standard; Appendix A says a Z308.1 kit is adequate for small worksites and larger sites may need more. So a Z308.1 kit satisfies the paragraph for most workplaces, and the employer adds to it where the OSHA 300 log or the hazards show the need.
What changed in ANSI Z308.1-2021? As the manufacturers' catalogs state, the 2021 edition added a tourniquet and a foil blanket to both classes, revised the hand sanitizer and eye wash quantities, kept the Class A and B structure introduced in 2015 and the Type I to IV containers, and asked employers to assess whether supplementary items such as bleeding control kits are needed.
