prospective formal review procedures planned

Primary objective. To map empirical evidence comparing approaches to occupational environmental heat-exposure measurement or assignment, with emphasis on exposure representativeness, risk-classification differences, and preventive decision implications.Primary question. How do ambient, regional, fixed-area, task-level, mobile, personal and modeled thermal exposure approaches differ in their representation of workers’ exposure, and under what reported circumstances do these differences affect heat-risk classifications or indicated preventive actions?
