A study was conducted at the autobody shop at Kay Parks/Dan Meyer Autorebuild (SIC-7531), Tacoma, Washington to evaluate orbital and in line sanders with high velocity, low volume exhaust hoods. Fourteen workers were employed in the autobody shop repairing cars and painting cars. Measurements made with an aerosol photometer showed that the use of the in line sander reduced worker exposure to aerosols by approximately a factor of 8. Worker particulate exposures were less than 1 to 2mg/m3 with the ventilated sanders. When air samples were collected in the breathing zone, a quantifiable mass of aerosol was not collected on the filter. Air samples were also analyzed for lead 7439921), cadmium (7440439) and chromium (7440473), and none of the metals were detected on any filter. Air contaminant exposure was measured while spray painting was done outside a spray painting booth. Air samples for particulates and solvent exposures were collected. Less than one pint of paint was used. During spray painting, solvent and total particulate exposures were below OSHA and NIOSH exposure limits. The authors conclude that the ventilated sanders appear to be useful for controlling workers exposures to aerosols during sanding. Spray painting outside of a painting booth did not cause excessive exposure if less than a pint of paint was used.
