NIOSH 1982 Sep:50 pages
An industrial hygiene survey was conducted at the Lehigh Cement Company, Mitchell, Indiana as part of a study of the effects of materials found in Portland Cement facilities on the human respiratory system. For most of the jobs at this facility, the respirable and total dust levels were below recommended exposure levels. One respirable dust sample from a dust collector exceeded the ACGIH recommended level for respirable nuisance particulate of 5mg/m3. Total dust samples from a crane operator, vacuum truck driver, and mill helper exceeded the 10mg/m3 MSHA standard for total nuisance dust. Two respirable dust samples from a laborer and a dust collector contained detectable levels of quartz (14808607); both exceeded the recommended limits. The authors recommend measures for reducing the hazards at this location, including engineering controls, use of protective equipment, and improving work habits.
