When considering how to keep safe during extreme heat, we need to look at more than just the thermometer reading. It’s not just the heat – it’s also the humidity.

In humid conditions, sweat can’t evaporate to keep your body cool. The heat index measures the level of discomfort the average person would experience from the combined effect of temperature and humidity.

The OSHA-NIOSH Heat Safety Tool provides information on how to stay safe when the heat index rises.

The tool features:

• A display of the current heat index and associated risk levels specific to your location.
• Precautionary recommendations specific to heat index-associated risks.
• An hourly forecast that will help plan outdoor work activities.
• Signs and symptoms and first aid for heat-related illnesses.

The OSHA-NIOSH Heat Safety Tool app is available for Apple and Android devices.
