 The rule put forth by the Occupational Safety and Health Administration would require employers to provide water, shade, brakes, and other precautions when temperatures and humidity exceed 80 degrees Fahrenheit. Stricter measures would be enforced when the heat index surpasses 90 degrees. WLTX 19 reports that if adopted, this rule would ensure the safety and well-being of workers exposed to high temperatures while working outdoors. I'm Katie Gray.
