Stay Cool: Avoid heat-related injury and illness
Justin Firaben, base lifeguard, raises a green flag June 23 at the pool on Bolling Air Force Base, D.C. The colored flag corresponds to the current wet bulb globe thermometer reading. A WBGT is an instrument that takes into account air movement, humidity, temperature and heat exchange, and produces a composite temperature. This composite temperature is used to estimate potential heat stress risk. (U.S. Air Force photo by Senior Airman R. Michael Longoria)
