What is ANSI?

The American National Standards Institute (ANSI) was founded in 1918. They provide standardization of many products in our daily lives.

In regards to workplace first aid kits/cabinets, the ANSI/ISEA Z308.1 -2021 determines the specific criteria and quantities of items that need to be in each first aid kit/cabinet in order to be compliant with the minimum standards. For most types of industries, OSHA defers to the ANSI Standard for minimum requirements.

Certain higher risk and heavily regulated industries may have their own standards that exceed the ANSI Standard.

ANSI Standards for First Aid Kits have recently been updated

The ANSI Standard for First Aid kits changed in 2021.  The revised assortment and quantity of supplies included in a first aid kit were chosen based upon a review of increased workplace incidents requiring first aid treatment, similar international standards, and current practices in treating injuries.

The revision includes two new classes of first aid kits:

  • Class A: Designed for the most common workplace injuries (minor cuts, sprains, abrasions)
  • Class B: Designed for more complex or high-risk environments
