Quick answer: a store-bought kit labeled ANSI/ISEA Z308.1-2021 Class A covers the basics for most homes and cars, because the standard sets a minimum list of items and quantities [1][2]. Pick the case for where it lives: a weatherproof case for the car or garage, a wall-mountable one for the house. Step up to Class B for higher-risk places such as a workshop [2]. Then add what no standard kit includes: your own prescriptions and glasses [3].

How we chose these kits
We didn’t open or use these kits. We picked them from the makers’ published contents lists and the public safety record.
- Filled to the current standard. ANSI/ISEA Z308.1 is a voluntary industry standard first published in 1978; the 2021 edition is its sixth revision [1]. Every pick is labeled by its maker as ANSI 2021 Class A or Class B [2][9].
- A case that fits the place. The standard also rates cases. Types I to IV run from wall-mounted indoor kits to rugged outdoor ones [2].
- A published contents list or piece count, so you can see what you’re getting and restock it later.
- No recall. We searched the CPSC’s recall list for each brand and its parent company on November 6, 2026 [4]. No First Aid Only or School Health kit was listed. First Aid Only is an Acme United brand [8], and Acme United did recall PhysiciansCare tablet packs in 2022 and 2023 because the packaging wasn’t child-resistant [5][6]; those were medicine packs, not these kits.
Two picks come from First Aid Only, because it publishes the item-by-item contents of each ANSI kit in one catalog. Plenty of other brands sell ANSI kits too; look for “ANSI/ISEA Z308.1-2021” and the class on the box.

Best for: A workshop, farm or rural home far from help
School Health 50 Person Bulk First Aid Kit, ANSI 2021 Class B, Metal Case
The only Class B kit here. School Health says it's built for complex or high-risk places such as labs, gyms and maintenance areas, and it adds a tourniquet, a 36-inch foam splint and a 4-ounce eyewash to bigger stocks of everything else [9].
- ANSI Z308.1-2021 Class B and OSHA, sized for 50 people; assembled in the USA [9]
- Gasketed metal case (a plastic case is also sold) [9]
- 50 plastic bandages, 4 gauze pads, 1 trauma pad (5 x 9 in), 2 gauze rolls [9]
- Arterial extremity tourniquet; foam splint, 4.25 x 36 in [9]
- 2 cold compresses, 2 burn dressings, 4 oz eyewash, 52 x 84 in emergency blanket, 52-page first aid guide [9]
Safety check: No CPSC recall found for School Health kits (checked 2026-11-06).
Watch out: It's big for a car, and it has only two pairs of exam gloves. A tourniquet and splint only help if someone knows how to use them, so consider a hands-on first aid class [9].

What to add to any kit
A standard kit is a starting point. Ready.gov’s disaster supply list suggests keeping these on hand as well [3]:
- Prescription medications.
- Prescription glasses and contact lens solution.
- Non-prescription medicines you already use, such as pain relievers or antacids.
- Soap, hand sanitizer and disinfecting wipes.
- Supplies for babies or pets, if you have them.
The standard itself leaves room for this: the ISEA says every workplace is different and kits should be supplemented to match the hazards [1].
Keeping it ready
- Check it monthly. The ISEA says at least once a month, and after every use [1].
- Restock with matching refills. First Aid Only sells refill packs for its 25- and 50-person Class A kits (items 91359 and 91360) [2], and School Health sells a 208-piece refill for its 50-person kit [9].
- Watch the dates. Ointments, eyewash and tablets expire. FDA posts recalls of drugs and medical products [7]; the CPSC covers the packaging and the kit itself [4].
- Keep medicine packs away from kids. The CPSC’s 2022 and 2023 recalls involved tablet packs that weren’t in child-resistant packaging, which the Poison Prevention Packaging Act requires for those medicines [5][6].

Common questions
What is an ANSI first aid kit?
A kit filled to ANSI/ISEA Z308.1, the American national standard for workplace first aid kits and supplies. The 2021 edition sets two content classes: Class A for the most common workplace injuries and Class B with a broader range and quantity of supplies for more complex or higher-risk settings.
What's the difference between a Class A and a Class B first aid kit?
Class B kits carry more supplies and more kinds of supplies than Class A kits. On this page, for example, School Health's 50-person Class B kit adds a foam splint and a tourniquet that the Class A kits don't have.
How often should I check a first aid kit?
The International Safety Equipment Association says workplace kits should be inspected at least monthly, and after any time supplies are used. Replace anything that's used up or past its expiration date.
Does a home first aid kit have to meet ANSI standards?
No. ANSI/ISEA Z308.1 is a voluntary standard written for workplaces. It's still a useful checklist for a home kit, because it sets minimum items and quantities.
