Advancing Exposure Assessment Strategy Across Global Operations

Ernest N. Morial New Orleans Convention Center 

How can global companies improve the consistency and efficiency of exposure assessments across work sites? A proof of concept was conducted to evaluate whether exposure data from similar processes and tasks across global sites could be compared to inform global Similar Exposure Group (SEG) exposure profiles. Personal exposure monitoring data for a single chemical were extracted from global sites. Site-specific worker groups were qualitatively grouped into global SEGs based on similar processes, tasks, work areas, and job positions, with validation from site industrial hygienists. Results demonstrated that this framework enables more consistent comparison and interpretation of exposure data for well characterized operations. Variability in task descriptions, work area definitions, and other contextual details limited validation of some SEGs, highlighting the importance of high quality contextual information to support effective global aggregation. This approach will reduce sampling burdens and foster a unified strategy for exposure evaluation across a global enterprise.
