General product and workplace-rule information only. It is not medical advice and does not replace a hazard assessment by a qualified safety professional.
This guide is for the person who must order first aid kits for several rooms, vehicles or sites at once, such as a facilities, safety or purchasing lead. After reading it you should be able to write a bulk order specification: which rule applies, which kit class to name, what unit of measure to put on the purchase order, which documents to request, and what to check when the cartons arrive.
What counts as a bulk first aid kit order?
A bulk first aid kit order is simply a purchase of many kits (or many refill packs) at once, usually quoted by the case or pallet. Nothing in the OSHA text or the ANSI/ISEA Z308.1 summary defines a “bulk” kit, a “wholesale” kit or a standard case size, so the pack count, the unit of measure (each, carton, case, pallet) and what is inside each unit must be written into your purchase order rather than assumed from a listing. The same applies to searches such as “first aid kit in bulk”, “buy first aid kits in bulk” and “wholesale first aid kit”: the wording describes how the seller sells, not what the kit contains.
Broader buying questions are covered elsewhere: how to vet a first aid kit supplier, what to verify on the label before a bulk medical supplies order, and which documents to ask for on wholesale medical equipment. This page covers the kit-specific workflow.
Which rule applies to the kits you are ordering?
The answer depends on the work setting, and a multi-site order can span more than one rule. Three sources matter, and they say different things.
| Source | Applies to | What it says about kits |
|---|---|---|
| OSHA 29 CFR 1910.151(b) | General industry | Where no infirmary, clinic or hospital is in near proximity for treating all injured employees, a person or persons must be adequately trained to render first aid, and “adequate first aid supplies shall be readily available.” It does not list kit contents. |
| OSHA 29 CFR 1910.151(c) | General industry | Where eyes or body may be exposed to injurious corrosive materials, suitable facilities for quick drenching or flushing must be provided within the work area for immediate emergency use. A kit order does not satisfy this on its own. |
| OSHA 29 CFR 1926.50(d) | Construction | First aid supplies must be easily accessible when required. Contents must be in a weatherproof container with individual sealed packages for each type of item, and the employer must check them before they go out on each job and at least weekly on each job so used items are replaced. |
| ANSI/ISEA Z308.1-2021 | Voluntary consensus standard for workplace kits | Defines Class A and Class B kits by quantity and assortment of contents. Approved 15 April 2021, effective 15 October 2021; the previous update was 2015. |
The practical consequence: a listing that says “OSHA compliant” is not a specification. The general industry rule sets no contents list, so that phrase cannot tell you what is in the box. The construction rule does set packaging and inspection conditions, which you can check on delivery. For the stocking side of the general industry rule, see the OSHA-compliant first aid kit stocking guide. State occupational safety plans may add their own requirements, so confirm them for each state where you have sites.
Class A or Class B: can one order cover every site?
Not necessarily. According to the standard owner’s statements reported by Safety+Health magazine (18 May 2022), ANSI/ISEA Z308.1-2021 keeps a Class A and a Class B minimum fill, and the two classes differ by the quantity and assortment of contents.
ISEA advises employers to run a workplace hazard assessment to choose the class. A bulk order for an office, a warehouse and a field crew may therefore need a mix: name the class per site on the purchase order instead of ordering one class everywhere because the case price or pack count suits you. If you want the item-by-item contents, use the contents guide; they are not repeated here.
What should be in a first aid kit?
For general industry, OSHA 1910.151 does not list contents, so the list comes from the class you specify under ANSI/ISEA Z308.1. The 2021 edition made foil blankets mandatory, requires tourniquets at least 1.5 inches wide sized for limb circumferences of 7 to 33 inches, adds bleeding-control supplies, and expands the discussion of hazard assessment. The same question appears as “what should be inside the first aid kit”, “what should first aid kit contain” and “what should you have in a first aid kit”; the answer is the same: it depends on the class and edition the kit is declared against. The full category-by-category list is in Items Inside a First Aid Kit.
What should I verify before placing a first order?
Check these before any pallet-sized commitment:
- The rule per site. Is each location general industry (1910.151) or construction (1926.50)? Does your state plan add anything?
- The class per site. Is it set by a documented hazard assessment, as ISEA advises?
- The edition. Does the seller name ANSI/ISEA Z308.1-2021 rather than an older edition (the previous update was 2015)? Items added in 2021, such as foil blankets and wide tourniquets, are a quick way to test this on a sample.
- The unit of measure. Is the quantity per kit, per carton or per case, and how many kits are in a carton?
- The container. For construction sites, is it weatherproof with individually sealed packages, as 1926.50(d)(2) requires?
What documents should I ask the seller for?
Documents are not mandated by OSHA for a kit purchase. The following is an editorial checklist tied to the facts above, not a rule:
- A written statement of which class and which edition of ANSI/ISEA Z308.1 the kit is declared against, and a contents list for that kit model.
- Expiry dates or lot identification for items that carry them, so you can set a replacement schedule.
- The carton quantity and contents per unit of measure, in writing on the quote or order confirmation.
Receiving, inspection and restocking
Open one carton per delivery and compare its contents to the written contents list before you distribute the rest. Then set a check cadence by site type:
| Site type | Check cadence | Basis |
|---|---|---|
| Construction | Before the kit goes out on each job and at least weekly on each job; replace expended items | OSHA 29 CFR 1926.50(d)(2) |
| Other workplaces | At least monthly or after use | ISEA encourages this; it is not a rule |
Keep a replenishment stock sized to your own usage, and record which kit sits where so a check can be traced to a location. These last points are editorial practice rather than requirements.
Mini kits and wholesale terms
A mini first aid kit sold in cartons is a separate line item from a full workplace kit. The sources describe Class A and Class B by quantity and assortment, so a small kit that is not declared against a class cannot be assumed to meet one (editorial reading). If minis are for vehicles or individual workers, decide whether they supplement or replace a class-declared kit at the site, and write that down. Wholesale terms (minimum order, refill program) are commercial matters between you and the seller and are not set by any rule cited here.
FAQ
Does OSHA say what must be in a bulk first aid kit?
No. 29 CFR 1910.151(b) requires adequate first aid supplies to be readily available and does not list contents. Construction work under 1926.50(d) adds a weatherproof container with individually sealed packages and weekly checks.
Which ANSI/ISEA edition is current?
ANSI/ISEA Z308.1-2021, approved 15 April 2021 and effective 15 October 2021, per Safety+Health magazine reporting ISEA.
Can I buy one class for all my sites?
Only if a hazard assessment supports it. ISEA advises using a hazard assessment to choose between Class A and Class B.
How often should kits be inspected?
On construction jobs, at least weekly under 1926.50(d)(2). For other workplaces, ISEA encourages at least monthly or after use.
What is the typical case or pack size?
None of the rules or standard summaries cited on this page sets one. Take the carton quantity and contents from the seller’s written quote and put it on the purchase order.
