Larry Sloan, CEO of the American Industrial Hygiene Association (AIHA), joins the OH&S Safety Pod to discuss the evolving risks of heat stress and how AIHA’s newly updated Heat Stress App is helping organizations protect workers in both indoor and outdoor environments.

The app uses live weather data and user inputs to calculate wet bulb globe temperature (WBGT), delivering personalized risk levels and clear, practical guidance. With multilingual support and a user-friendly interface, it empowers frontline workers, supervisors, and safety leaders to make smarter heat-related decisions.

Larry explains why heat stress is often underestimated, how app feedback shaped its latest features, and why real-time tools like this are essential for modern safety programs. He also outlines the app’s global usability, practical applications, and the role of prevention in reducing costly, often avoidable incidents.

This episode offers timely insights for safety professionals preparing for peak heat season—and committed to keeping teams safe, alert, and productive.
