Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: The study is a parallel, comparison, group intervention study to evaluate the effectiveness of a multi-level Heat Education and Awareness Tools (HEAT) intervention, consisting of worker training and a supervisor heat awareness application, on reducing adverse heat health effects in agricultural workers across a growing season.
Primary purpose: PREVENTION

Brief summary: The project's primary aim is to evaluate the effectiveness of a multi-level heat prevention approach in reducing adverse heat health effects in outdoor agricultural workers

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


Eligibility criteria: Inclusion Criteria:

* Speak English or Spanish, live in same dwelling and work at same farm for the season, farm where participant works must agree to collaborate
