Title Exposures to quartz, diesel, dust, and welding fumes during heavy and highway construction
Bibliographic information July-Aug. 2002, Vol.63, No.4, p.447-457. 62 ref.
Abstract Personal samples for exposure to dust, diesel exhaust, quartz and welding fume were collected on 260 heavy and highway construction workers. Respirable quartz exposures exceeded the National Institute for Occupational Safety and Health (NIOSH) recommended exposure limit (REL) in 7-31% of cases for the jobs sampled. More than 50% of the samples in the installation of ceilings, wall tiles and concrete finish operations exceeded the NIOSH REL for quartz. Thoracic exposures to quartz and dust exceeded respirable exposures by a factor of 4.5 and 2.8, respectively. Inhalable exposures to quartz and dust exceeded respirable exposures by a factor of 25.6 and 9.3, respectively. 14% of the personal samples for elemental carbon collected as a marker for diesel exhaust, exceeded the American Conference of Governmental Industrial Hygienists (ACGIH) threshold limit value (TLV) for diesel exhaust. 17 of the 22 samples taken during a partially enclosed welding operation reached or exceeded the ACGIH TLV of 5 mg/m3 for welding fume.
