Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The secondary aims are to:
* Test the effectiveness of an individual-level training component designed to reduce adverse heat health effects in outdoor agricultural workers
* Evaluate the effectiveness of a workplace supervisor-level heat awareness application intended to support supervisor decisions to reduce the risk of workers experiencing adverse heat health effects

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
HEAT intervention group
Workers in the intervention group will receive the HEAT training, and supervisors in the intervention group will receive the HEAT awareness application and training on how to use it.
Heat Education and Awareness Tools
HEAT training will be delivered to agricultural workers by research staff in this study in the spring. HEAT training uses interactive approaches to engage participants and posters with visuals. Training covers types of heat-related illness and treatments, risk factors, appropriate clothing and hydration, and keeping cool in the home and community. The HEAT awareness application was developed in collaboration with Washington State University's AgWeatherNet Program to notify supervisors signed up for the service about hot weather conditions that might increase the risk for adverse health effects for workers. The HEAT awareness application is designed to allow subscribers to select weather stations of interest and view current heat indices as well as maximum daily heat indices forecasted over the following week. This information is coupled with information about health effects and prevention of adverse heat health effects. Materials are provided in English and Spanish.
Comparison group
The comparison group will not be offered HEAT trainings or the HEAT awareness application. They will be offered an alternative training on another topic.
No interventions assigned to this group
