Cal/OSHA is advising employers across California to maintain required heat protections as high temperatures affect much of the state.
At outdoor worksites, employers must provide fresh water and access to shade when temperatures exceed 80 degrees. Workers must also be allowed to take cool-down breaks when requested.
California’s indoor heat standard applies to most workplaces when temperatures reach 82 degrees. Covered workplaces include restaurants, warehouses and manufacturing facilities.
Additional requirements take effect at 95 degrees for agriculture, construction, landscaping, oil and gas extraction and certain transportation operations. Employers in those industries must monitor workers for signs of heat illness and maintain effective communication procedures.
Employers covered by the indoor or outdoor standards must maintain written heat illness prevention plans. Supervisors and employees must also receive training on recognizing symptoms and responding to heat-related emergencies.
