Cal/OSHA High Heat Advisory: Employers Reminded to Protect Outdoor Workers from Heat Illness
Oakland —Cal/OSHA is reminding all employers to protect outdoor workers from heat
illness as excessive heat warnings and watches have been issued throughout the state,
with triple digits forecast through Monday, July 12. Employers in California must take
steps to protect outdoor workers from heat illness by providing water, rest, shade and
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 potable
drinking water, access to shade when temperatures reach 80 degrees and whenever
requested by a worker, cool-down rest breaks in addition to regular scheduled breaks,
and establish an effective written heat illness prevention plan with training on the signs of
heat illness and what to do in case of an emergency.
It is important for employers to assess the risk of heat illness based on a worker’s duties
and take appropriate steps to prevent them from getting sick. Regardless of the level of
risk, all outdoor workers must be protected equally and employers with outdoor workers
must implement and maintain an effective heat illness prevention plan year-round.
