Workplace First Aid Kit Requirements: OSHA and ANSI Z308.1

Workplace First Aid Kit Requirements

Updated November 6, 2026

What Does OSHA Require for a Workplace First Aid Kit?

OSHA requires adequate first aid supplies to be readily available, and a trained first aid person if no clinic or hospital is close, under 29 CFR 1910.151. It sets no fixed kit list, but points to ANSI Z308.1 as a guide. Class A kits suit common injuries; Class B kits suit busier or riskier sites.

Class A or Class B

Class A: common wounds, minor burns and eye injuries, for lower-risk sites.
Class B: a broader, larger set for crowded, complex or higher-risk sites.

How to Choose

Look at your injury log and your actual hazards.
Scale up for headcount and shifts, and consider several kits on big sites.
Add items for specific risks, such as burn or eye-wash supplies.
Corrosive chemicals call for quick-drench or eye-wash facilities under 1910.151(c).

Keep It Ready

Assign someone to check kits regularly, replace used and expired items and note the date. Get people trained at a CPR and first aid class. Construction sites have a parallel rule at 29 CFR 1926.50.
