It is crucial to accurately distinguish between Wet Bulb Globe Temperature (WBGT) and Wet Bulb Temperature, especially when it comes to health and safety guidelines. Confusing these two metrics can—and has—led to fatal outcomes.
Wet Bulb Globe Temperature (WBGT) is a composite index that estimates heat stress on humans by considering temperature, humidity, wind speed, and solar radiation. It’s a vital tool in guidelines for managing heat stress in various environments.
Wet Bulb Temperature, on the other hand, is just one component of WBGT. It represents the lowest temperature air can reach through evaporative cooling under current atmospheric conditions.
Mistaking Wet Bulb Temperature for WBGT can lead to a severe underestimation of heat stress, putting people in dangerous situations.
Until next time, stay cool! 😎
