Project Type: Analysis

Project Description: This study will assess both the environmental and physiological conditions in the field crop work environment and field crop workers. A research model and data collections systems will be developed to evaluate factors influencing the risk of heat related illness. Data will be analyzed and intervention strategies for preventing heat related illness will be proposed. Findings from field investigations during summer 2001 indicate that the heat index within a row crop is commonly 8-10 degrees F greater than that reported by the National Weather Service for the area. Investigators also learned that workers in the study were already beginning to dehydrate prior to feeling thirsty. Research in summer of 2002 continued to examine this important aspect of worker health and safety.
