Employers should encourage workers exposed to hot and humid conditions to use the app to check the heat index and relevant protective measures. The app displays the heat index in the user’s location and shows the current risk level. The app also forecasts the hourly heat index throughout the entire workday, giving employers information they can use to adjust the work environment as needed to protect workers.
More than 450,000 users have downloaded the original app since it was launched in 2011. The original OSHA app will no longer function after September 30. To download the updated app and get more information on OSHA’s efforts to help protect workers from the heat, visit our heat campaign webpage.
