Why First Aid Readiness Saves Lives
When a workplace injury or medical emergency occurs, the minutes before professional medical help arrives are critical. A well-stocked, properly maintained first aid kit — and trained employees who know how to use it — can be the difference between a minor incident and a life-altering outcome. Yet many organizations treat their first aid kits as a compliance checkbox rather than a genuine life-safety resource.
This guide covers OSHA's first aid requirements, what every workplace kit should contain, how to determine how many kits you need, and how to keep them properly maintained.
OSHA's First Aid Requirements
OSHA standard 29 CFR 1910.151 requires that employers ensure the ready availability of medical personnel for advice and consultation on matters of plant health. In the absence of an infirmary, clinic, or hospital near the workplace, employers must have a person or persons adequately trained to render first aid, and adequate first aid supplies readily available.
OSHA references ANSI/ISEA Z308.1 as the standard for minimum first aid kit contents. The most current version classifies kits by type:
- Type I: Designed for fixed, indoor use in a controlled environment (office, light industrial)
- Type II: Portable for semi-fixed or indoor use
- Type III: Portable for mobile or outdoor use
- Type IV: Ruggedized for extreme environment use (mining, offshore, remote worksites)
Minimum First Aid Kit Contents (ANSI/ISEA Z308.1)
Class A kits cover the most common workplace injuries. Class B kits provide a broader range of supplies for more complex environments. Below is a summary of Class A minimum requirements:
| Item | Minimum Quantity |
|---|---|
| Absorbent compress (32 sq. in. minimum) | 1 |
| Adhesive bandages (1" x 3") | 16 |
| Adhesive tape (2.5 yd) | 1 |
| Antibiotic application | 10 packets |
| Antiseptic (0.5 g application) | 10 packets |
| Breathing barrier (CPR face shield) | 1 |
| Burn dressing (min. 4" x 4") | 1 |
| Burn treatment (0.5 g application) | 6 packets |
| Cold pack | 1 |
| Eye/skin wash (1 fl. oz. minimum) | 1 |
| Gloves (medical grade, pair) | 2 pairs |
| Roller bandage (2" x 4 yd) | 1 |
| Scisssors | 1 |
| Sterile pads (3" x 3") | 4 |
| Tourniquet | 1 |
| Triangular bandage (40" x 40" x 56") | 1 |
How Many Kits Does Your Workplace Need?
The number and placement of first aid kits depends on your facility size, the number of employees, the nature of the hazards, and travel time to the nearest kit. General guidance:
- Place kits so that no employee has to travel more than 3–5 minutes to reach one.
- In multi-story buildings, provide at least one kit per floor.
- In high-hazard environments (chemical plants, construction sites), increase kit density and upgrade to Class B.
- Mobile workers should carry a portable kit in their vehicles.
Maintaining Your First Aid Kits
A first aid kit is only useful if it's complete, unexpired, and accessible. Implement the following maintenance practices:
- Monthly visual inspections: Check that the kit is stocked, sealed, and free from moisture damage or contamination.
- Immediate restocking: Replace any used or expired items as soon as they are removed or discovered.
- Annual full audit: Compare contents against ANSI/ISEA standards and replace all expired items.
- Clear signage: All kits must be clearly marked with a first aid cross symbol and visible from a reasonable distance.
- Unobstructed access: Never block, lock, or relocate a kit without updating employees on its new location.
Going Beyond the Kit: First Aid Training
A stocked kit without trained users is of limited value. OSHA recommends — and some state plans require — that at least one trained first aid provider be available at all times during work hours. First aid and CPR/AED certification courses through organizations such as the American Red Cross or the American Heart Association are widely available, typically lasting 4–8 hours. Refresher training every two years keeps skills sharp and certifications current.
Consider also designating trained employees on each shift and in each department, particularly in high-hazard areas, to ensure coverage regardless of who is on duty.
