UC Davis Departments with any outdoor places of employment must adhere to the Cal/OSHA Heat Illness Prevention Standard.

The Cal/OSHA Heat Illness Prevention Standard, Title 8 California Code of Regulations Section 3395 outlines four steps to prevent heat illness:

1. Planning - Develop and implement written procedures for complying with the Cal/OSHA Outdoor Heat Illness Prevention Standard.
2. Training - Train all employees and supervisors on heat illness recognition and prevention.
3. Water - Provide enough fresh water so that each employee can drink at least 1 quart per hour and encourage them to do so.
4. Shade - Provide access to a shaded area to prevent or recover from heat illness and where employees can take rest breaks.

To assist UC Davis departments in establishing and implementing a heat illness prevention program, this Heat Illness Prevention Procedure Manual has been prepared by the Office of Environmental Health & Safety in accordance with Cal/OSHA regulations and University policy.

Employees and supervisors who perform work that should reasonably be anticipated to result in exposure to the risk of heat illness must receive heat illness training that covers all topics discussed in the Standard. Please note that as of 2024, the LMS Heat Illness Prevention Training module has been amended to include training requirements for both the outdoor and indoor regulations. A supplemental Heat Illness Prevention Training PDF is available to aid departments in complying with the training element of the standard.

Additional information regarding Heat Illness can be found in SafetyNet #123 and on the Cal/OSHA website.
