Abstract The purpose of this study was to determine the efficacy of current methods and methods proposed by the P.I. to 'troubleshoot' industrial exhaust ventilation systems using measured pressures and flows. Exhaust ventilation systems for contaminant control often experience obstructions and other deleterious alterations to individual ducts. Those alterations can reduce airflow to hoods, reducing their reliability in controlling exposures to hazardous airborne contaminant. Since alterations often are hidden from sight inside opaque ducts, it is necessary to find them using indirect means, primarily by interpreting changes to observed airflows and pressures.
