OSHA-NIOSH Heat Safety Tool


The U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) and Centers for Disease Control and Prevention's National Institute for Occupational Safety and Health (NIOSH) Heat Safety Tool is a useful resource for planning outdoor work activities based on how hot it feels throughout the day. The app features real-time heat index and hourly forecasts, specific to your location, as well as occupational safety and health recommendations from OSHA and NIOSH. With a click, the disaster workforce can get reminders about the protective measures that should be taken at each risk level to protect workers from heat-related illness. The app includes information such as:

  • Drinking enough fluids
  • Scheduling rest breaks
  • Planning for and knowing what to do in an emergency
  • Adjusting work operations
  • Gradually building up the workload for new workers
  • Training on heat illness signs and symptoms
  • Monitoring each other for signs and symptoms of heat-related illness
