In this safety video, Rachel from Ally Safety educates listeners on measuring environmental heat to prevent heat illnesses. She highlights that the perception of heat involves air temperature, humidity, radiant heat, and air movement. Rachel introduces wet bulb globe temperature monitors (WBGT) for a comprehensive heat assessment, noting their historical significance in reducing military heat illnesses. She also discusses data logging meters for tracking heat over time, personal heat stress monitors for individual alerts, and handheld heat index stopwatches for cloudy, low-wind conditions. Rachel advises on setting exposure limits and recommends safety measures to prevent heat-related illnesses.
