XMD Heat Index Guide

Current Data

The heat index is a simple tool and a useful guide for employers making decisions about protecting workers in hot weather. It does not account for certain conditions that contribute additional risk, such as physical exertion. Consider taking the steps at the next highest risk level to protect workers from the added risks posed by:
  • Working in the direct sun (can add up to 15°F to the heat index value)
  • Wearing heavy clothing or protective gear
