Industrial cabinet first aid kits are available in ANSI Class A and Class B compliant versions. Class A kits are perfect for low-risk environments with fewer hazards such as most offices, offering essential supplies for common injuries like cuts, abrasions, and minor burns. Class B kits are intended for higher-risk environments, such as factories or construction sites, where more serious injuries like major bleeding, fractures, and burns are more likely containing a broader range of supplies. Both Class A and Class B are available in different sizes depending on the number of employees.
