Protecting Outdoor Workers from Heat Illness During Periods of Excessive Heat

In California, employers with outdoor workplaces are mandated by Section 3395 of Title 8 of the California Code of Regulations to establish a Heat Illness Prevention (HIP) plan. This regulation is designed to safeguard employees from heat-related illnesses, which can lead to serious health conditions such as heat cramps, heat exhaustion, and heat stroke. The HIP plan should encompass provisions for sufficient water, shade, rest periods, and emergency response procedures. Additionally, it necessitates employers to offer training to all employees about the prevention of heat illness. Adherence to this plan not only promotes the well-being of employees but also ensures compliance with state regulations, helping to avoid potential legal and financial consequences.

California Department of Industrial Relations, Division of Occupational Safety and Health (DOSH) provides several resources and an e-tool to assist employers with their Heat Illness Prevention program and procedures.
