California Faces Triple-Digit Heat: Cal/OSHA Issues Worker Safety Alert
US · Published Sep 10, 2026
Cal/OSHA has issued a heat alert as temperatures across California are expected to reach triple digits in many areas, including Southern California, the Central Valley, and parts of Northern California.
Employers are being reminded of their legal obligations to protect workers from heat-related illnesses in both indoor and outdoor settings.

Impact & Risks

The extreme heat poses significant risks to workers, particularly those in agriculture, construction, landscaping, and other outdoor industries. Heat illness can lead to severe health complications or even fatalities if not addressed promptly. Indoor workers in environments such as warehouses and restaurants are also at risk when temperatures exceed 82°F (27.8°C). Employers failing to comply with heat safety standards may face legal consequences. Vulnerable populations, including outdoor laborers and those working in high-heat indoor settings, are most at risk of heat-related illnesses.
