As outdoor temperatures begin to rise, so does the chance of illnesses related to working outside. Heat stress and overexposure to the sun's ultraviolet rays can cause deadly effects - both in the short and long run. OSHA, which has long led a campaign to prevent heat illness in outdoor workers, relaunched the Water. Rest. Shade. Campaign. OSHA has a revised version of its Heat Safety Tool app available for Apple (iOS) and Android devices in both English and Spanish, the app now has full screen color alerts for all heat conditions, improved navigation and accessibility options and compatibility upgrades.

The app provides heat illness prevention guidance specific to the user's current outdoor workplace conditions using weather data provided by the National Oceanic and Atmospheric Administration. The new version of the app provides the daily maximum heat index, allowing workers to prepare for extreme heat and enabling supervisors to plan work schedules accordingly. #WaterRestShade
