The wet-bulb globe temperature (WBGT) index was originally developed based on the weighting of three environmental parameters: dry-bulb temperature, wet-bulb temperature and black globe temperature. A shielded dry-bulb thermometer, a natural wet-bulb thermometer and a globe thermometer (a black globe heated by solar radiation) are used to capture these environmental parameters. The WBGT index was later standardized ... and is now widely used as a heat stress index throughout the world, with the guidelines and permissible threshold limits in many industries, including construction and underground mining operations, being based on this measure.
