Under recent revisions, employers are required to provide shade when temperatures reach 85 degrees Fahrenheit and to institute "high-heat" procedures (such as observing employees for signs of illness and reminding employees to drink water) at 95 degrees. The revisions also state that heat illness training should be provided to employees before they begin work reasonably anticipated to result in exposure to the risk of heat illness. These rules apply to employers in the agricultural, construction, landscaping, oil and gas extraction and transportation and delivery industries who have employees working outdoors.
