High temperatures and extreme heat are dangerous and life-threatening. These conditions at work, especially in a physically intensive work environment, are particularly dangerous.

Over the summer, at least half a dozen workers documented heat illness at KSBD, Amazon’s West Coast Air Freight Fulfillment Center, and as temperatures soared into the 90s and 100s, the workers at KSBD formulated their demands and directly approached Amazon warehouse management on Aug. 31 and Sept. 2 to win protections from extreme heat. Then workers representing every department at the facility took thermometers to work for seven days and recorded the temperatures throughout the day. At one point, on Sept. 4, workers recorded a temperature of 121 degrees in an outdoor work area.
