Industrial Hygiene Survey of Lone Star Cement Co., Nazareth, Pennsylvania. Cement Workers Morbidity Study.
NIOSH 1982 Sep:41 pages
As part of the Cement Workers Morbidity Study, an industrial hygiene survey was conducted at the Lone Star Cement Company in Nazareth, Pennsylvania. Environmental sampling was conducted to determine the presence and concentration of various contaminants. For most jobs at this site the levels of respirable and total dust were below the permissible limits. One sample for a mill helper exceeded ACGIH recommended levels for respirable nuisance particulate (5mg/m3). Total dust samples for a maintenance worker and a packer exceeded the MSHA 10mg/m3 standard for nuisance dust. Eight respirable dust samples contained detectable levels of quartz (14808607), and three exceeded the MSHA permissible exposure limit. The authors recommend that measures be taken to reduce exposures, including the use of ventilation systems, personal protective equipment, and improving clean up procedures.
