As temperatures are projected to hit triple digits across the state with
prolonged heat waves, Cal/OSHA reminds employers with outdoor workers that shade
must be made available at all times, and must be in place when temperatures reach 80
degrees or above.
The National Weather Service has issued excessive heat warnings and high heat
advisories statewide, especially in inland areas. Periods of prolonged, widespread triple
digit heat is expected tomorrow through Thursday in downtown Los Angeles and much
of Southern California’s inland areas, as well as in the Bay Area, Monterey, Sacramento
and Central Valley regions.
Cal/OSHA urges workers experiencing possible overheating to take a preventative cooldown
rest in the shade until symptoms are gone. Workers who have existing health
problems or medical conditions that reduce tolerance to heat, such as diabetes, need to
be extra vigilant. Some high blood pressure and anti-inflammatory medications can also
increase a worker’s risk for heat illness.
Staying properly hydrated throughout the workday is one of the most effective heat
illness prevention techniques. Cal/OSHA encourages all workers to drink at least one
quart of water every hour, preferably sipping an 8-ounce cup of water every 15 minutes.
Drinks such as soda, sports drinks, coffee, energy drinks or iced tea are not
recommended for hydration. Also, the lingering effects of alcoholic beverages can
contribute to quickly dehydrating the body in hot weather.
In addition to the basic steps outlined by California’s heat regulation for employers with
outdoor workers, heat at or above 95 degrees Fahrenheit requires additional
precautions. Among other measures, it is crucial that workers are actively monitored for
early signs of heat illness. This helps ensure sick employees receive treatment
immediately and that the symptoms do not develop into serious illness or death.
In case a worker does get sick, supervisors and coworkers must be trained on the
emergency procedures required to ensure that the sick worker receives treatment
immediately and serious illness does not develop.
Cal/OSHA inspects outdoor worksites in agriculture, construction, landscaping, and
other operations throughout the heat season.
