When the human body gets warmer than 104 degrees Fahrenheit, it is considered to be a medical emergency called heat stroke. If an employee shows signs of heat stroke or other heat related medical issues, it is imperative to get medical help right away. In some cases, it may be necessary to call 911. Workers should be moved to a shaded area and given air and cold water. Additional signs of heat stroke include a lack of sweating, confusion and seizures.
