HRI is a serious health risk for agricultural workers that can result from prolonged exposure and overexertion in hot temperatures. The four different types of HRI in increasing severity are heat rash, heat cramps, heat exhaustion, and heat stroke. These conditions are preventable using simple approaches such as proper hydration and limiting one's time in the sun. To better equip agricultural supervisors and safety trainers responsible for conveying heat safety to their workers, I collaborated with members of University of Washington’s Pacific Northwest Agricultural Safety & Health (PNASH) Center to develop a modular flipbook that will serve as training material, covering the following topics: symptoms, risks, and treatments, clothing, hydration, and other preventative measures; as well as where and how to cool off in the home and community. I helped advance this project by taking the lead on the production of the flipbook content under the direction of the Research Scientist. I collated images, researched instructional designs, and developed prototypes of the flipbook, as well as edited the written instructions for facilitators. The educational activities in the book consists of an interactive portion, guiding questions for the facilitator to pose to the group, role-play scenarios, take-home points to reinforce the educational messages, and 3-dimensional educational charts. Modules also contain a “Knowledge Evaluation” section with questions for the facilitator to ask participants both before and after the activities to gauge their change in knowledge and to ensure the material has been understood. As a final product, the flipbook will be a portable and convenient resource for safety trainers to use in the field. My goal is to ultimately make this flipbook accessible to the general public, as it is not only a great safety resource for agricultural workers, but also for their families and surrounding community.
