The WBGT index is a heat stress indicator used to gauge the relative severity of environmental temperature on the human body by measuring humidity, wind speed, and sunlight and then compositing the information into an actual temperature experienced by personnel. The index consists of five color-coded categories with associated temperature information derived from the WGBT and specifies fluid intake requirements and work allowed. Flags with corresponding colors are flown to indicate current heat and work conditions.
