• Description:
  Aircraft painting can be a hazardous process. Ventilation and other protective measures are necessary to prevent exposure of workers to toxic chemicals, such as isocyanates and chromates, which are contained in the paints. In 2008, researchers from CDC/NIOSH began work on a collaborative project with the U.S. Navy to evaluate ventilation in a Navy aircraft painting hangar at Naval Base Coronado as part of the Navy Environmental Sustainability Development to Integration (NESDI) program. Computational fluid dynamics (CFD) modeling was used in conjunction with on-site tracer gas experiments to assess air flow conditions in the hangar and to investigate design alternatives. The project determined that a reduction in delivered airflow might not increase contaminant exposure. This counterintuitive finding resulted in an interest in expanding the project to encompass more sites around the U.S. with support from the Environmental Security Technology Certification Program (ESTCP). Three additional sites were chosen for study inclusion: Marine Corps Air Station Cherry Point, Sioux City Air National Guard Base, and Joint Base Lewis-McChord. A four-step process of site assessment, CFD analysis, tracer gas validation, and exposure testing was planned for the assessment of each site. However, work on this ESTCP hangar ventilation project was officially halted in February, 2014, and remains unfinished. The four-step assessment protocol has been completed for the Naval Base Coronado site. The other three sites remain at various stages of the site assessment process. Initial site visits suggest these locations are good candidates for additional investigation. Continuing research and the implementation of more efficient ventilation systems at these locations could yield significant benefits in the form of energy cost savings and better worker protection. This report provides a summary of results from the site visits and discusses areas of potential future research.
