title: Evaluation of ventilated sanders in the autobody repair industry.
abstract: Orbital and reciprocating sanders were evaluated in autobody shops to obtain information on the ability of the sanders to control worker dust exposures. Air is exhausted from ventilated sanders at a rate of 0.25 to 1.0 m3/min. When unventilated sanders were used, short-term total dust exposures ranged between 2 and 170 mg/m3. When ventilated sanders were used, short-term total exposures ranged between 0.22 and 1.2 mg/m3. Aerosol photometer measurements showed that ventilation decreased dust exposure by a factor of 10 when body-filling compound was sanded. These results indicate that the use of sanders equipped with high-velocity, low-volume ventilation should be encouraged in the autobody repair industry.
