According to OSHA, the "heat index" is a single value that takes both temperature and humidity into account. The higher the heat index, the hotter the weather feels. The heat index is a better measure than air temperature alone for estimating the risk to workers from environmental heat sources.
The app combines heat index data from the U.S. National Oceanic and Atmospheric Administration with the user's location to determine necessary protective measures. Based on the risk level of the heat index, the app provides users with information about precautions they may take, such as drinking fluids, taking rest breaks and adjusting work operations. Users also can review the signs and symptoms of heat stroke, heat exhaustion and other heat-related illnesses, and learn about first aid steps to take in an emergency. Information for supervisors is also available through the app on how to train employees on heat illness signs and symptoms. Additionally, users can contact OSHA directly through the app.
The app is also available in a Spanish version.
