The U.S. Occupational Safety and Health Administration (OSHA) and National Institute for Occupational Safety and Health (NIOSH) have developed a real-time heat index app that helps employers and employees plan work around the heat. The app gives users hourly heat forecasts for individual locations and also provides safety and health recommendations on preventing heat illness. 

The app could be especially useful to employers and farmworkers in California and Arizona who have been experiencing extreme heat conditions over the last couple of weeks.
