A Multi-Level Approach to Heat Related Illness Prevention in Agricultural Workers

This study works in collaboration with Washington state growers and workers, farmworker housing partners, and Washington State University’s AgWeatherNet. This participatory intervention project introduces timely heat safety guidance to employers.

To date, the project team and its advisory board have completed English and Spanish versions of the participatory training program, “Heat Education & Awareness Tools (HEAT): A train-the-trainer guide for the identification, prevention, and treatment of heat illness in outdoor agricultural workers.” Additionally, the Heat Awareness app developed in conjunction with WSU AWN has been finalized and released in English and Spanish. Once downloaded, a user selects the WSU AWN weather station(s) of interest. When a hot day is forecasted, a notification provides a worker health risk category and agriculture-specific recommendations.

Findings as reported at the end of year five are included in our interim report.
