A study was undertaken at Jeff Wyler Autobody Shop (SIC-7532), Batavia, Ohio to evaluate practical, commercially available control methods to lessen employee exposures to air contaminants at autobody repair and painting shops. Two unventilated sanders, two spray painting booths with semi downdraft ventilation systems, and respirator usage were evaluated. This autobody shop employed 19 workers including seven body repair technicians, seven painters, and five office workers. About 30 to 40 vehicles were repaired each week. The use of the semi downdraft spray painting booths appeared to minimize worker exposure to paint overspray while most of the vehicle was painted. Most overspray was controlled by the air velocities around the vehicle. Some overspray was, however, transported into the worker's breathing zone when the worker aimed the spray gun into the booth's oncoming airflow or stood between the inflow plenum and the area being painted. During sanding operations, total dust concentrations on workers' lapels exceeded 15 milligrams per cubic meter. The authors recommend that the purchase of a central vacuum system and ventilated sanders be considered. Respirator usage in this shop was found to be inadequate; the authors indicate that a complete respiratory protection program as defined in OSHA standards needs to be implemented.
