During California’s extended heat wave, public agencies have issued additional guidance for schools and staying safe during outdoor activity, adding to already existing guidelines about preventing heat illness for workers.

California Department of Health

• The CDPH  provides information about extreme heat and preventing heat illness.
• CDPH also offers interim health guidance for schools on “Sports and Strenuous Outdoor Activities during Extreme Heat.” The interim guidance provides additional or supplemental information; if a school or local jurisdiction has an existing heat emergency plan, consult with the existing plan first.

Department of Industrial Relations

• Cal/OSHA reminds all employers to protect outdoor workers from heat illness as excessive heat watches have been issued in many areas around California.
• Cal/OSHA’s heat illness prevention standard applies to all outdoor worksites. To prevent heat illness, the law requires employers to provide outdoor workers fresh water, access to shade at 80 degrees and whenever requested by a worker, cool-down rest breaks in addition to regular breaks and maintain a written prevention plan with training on the signs of heat illness and what to do in case of an emergency.
• Details on heat illness prevention requirements and training materials are available on Cal/OSHA’s Heat Illness Prevention web page. 
• And on the 99calor.org informational website.
• Cal/OSHA also has an online tool for Heat Illness Prevention.
