Reduction in the environment, safety, and occupational health (ESOH) component of operational costs requires not only a better understanding of ESOH costs and requirements, but also the formation of effective partnerships between ESOH professionals, financial analysts, and shop workers to identify viable improvements to current practices. This article presents two case studies of efforts to enhance productivity and ESOH in corrosion control facilities at Randolph Air Force Base (AFB), Texas, and Robins AFB, Ga. At each site, activity-based cost models were created to increase the visibility of ESOH-related costs and target improvement opportunities. Analysis of the strip-and-paint processes for the T-38 aircraft at Randolph and the F-15 radome and C-141 aft cowl at Robins revealed that a large proportion of operating costs were tied to ESOH requirements and practices (22 and 39%, respectively). In each case ESOH professionals teamed with shop personnel to identify potential improvements in personal protective equipment use, waste disposal, tool selection, and work methods. This approach yielded alternatives projected to reduce total shop costs by 5 to 7%. This case study demonstrates how workplaces can identify cost-saving and efficiency-enhancing practices by partnering with ESOH professionals in planning and decision-making activities.
