In California, employers must have a heat illness prevention program for outdoor workers.

Now that June has arrived, the official summer season has begun. If you are an employer with outdoor workers, such as those in the agricultural, construction, and landscaping industry, you must have a training and prevention plan to combat heat illness.
- Water
- Rest
- Shade
The training must include how to recognize signs and symptoms of heat illness, as well as procedures to respond to possible heat illness.
