Heat Illness Prevention


Heat-related fatalities among outdoor workers in recent years have captured much attention, especially since most cases of heat stroke are preventable. Low-wage immigrant farm workers are some of the most vulnerable. Since 2006, California’s Heat Illness Prevention Standard (GISO 3395) has required that employers provide plenty of water, shade to rest and cool down, training and adequate emergency plans. LOHP has been working on developing effective ways to reach workers and their employers with key information. In 2007, LOHP piloted a community-based initiative “Protecting California’s Farm Workers from Heat-Related Illness: Piloting Health and Safety Communication Strategies for Hard-to-Reach Farmworkers,” in Mendota, CA a town where half of the mostly Latino population (est. 7,500) work in agriculture. Through this project LOHP tested a community-based social marketing model that included a health fair, community block parties, outreach through promotoras, and development of posters and bandanas as give-aways.

Heat illness can be deadly – but by making heat safety part of the job, employers and workers can work longer, feel stronger and stay healthy. This summer’s campaign includes a combination of media, education and enforcement efforts. Strategically targeting the most underserved populations of outdoor workers and including messages in Spanish, Punjabi, Hmong, Mixteco, and English, the campaign addresses heat safety, prevention and workers’ rights.

We invite you to join in this effort by helping to reach workers and employers in your community with the resources you will find on this site, including:

  • For workers – materials are highly graphic, easy-to-read and available in Spanish, Hmong, Punjabi and English.
  • For employers – training materials to help meet the California Heat Illness Prevention Standard (GISO 3395) requirements and keep employees safe and productive.
