The Heat (App) Is On!

Heat illness sickens thousands of workers every year, and severe cases can be fatal. To help keep outdoor workers cool, the Occupational Safety and Health Administration developed a free app to calculate worksite heat index and risk levels, and educate users about how to respond to a heat emergency. More than 187,000 people have downloaded the app since its 2011 launch. In the app’s first big update on May 5, iPhone users discovered new features. With an attractive, easy-to-use interface, the new version is optimized for the latest iPhones. The app automatically provides the current conditions and maximum heat at your location and can accept manual input if users don’t have cell service.
