In-Depth Survey Report: Control Technology for Autobody Repair and Painting Shops at Valley Paint and Body Shop, Amelia, Ohio

摘要

A study was undertaken to evaluate the effectiveness of commercially available control methods for reducing hazardous exposures at the Valley Paint and Body Shop (SIC-7532), Amelia, Ohio. The shop employed seven technicians: five repaired cars and two painted cars. The use of the downdraft spray painting booth seemed to minimize exposure to paint overspray when the sides of the cars were being painted. This type of booth, however, did not serve as an effective control when individual autobody parts were being painted. Meaningful control of paint overspray was lacking probably because the air velocity at the vehicle preparation station was not adequate. Overspray could be directly transported into the breathing zone of the worker due to the configuration of the vehicle preparation station. Respirators were not adequately or properly used at this location. Air supplied hoods were used to control exposures to overspray, and half face air purifying respirators were used during some sanding and welding operations. Of six half face respirators, four had fit factors of less than 50 and two had fit factors of less than 10.
