Industrial Hygiene Survey of General Cement Co., Fredonia, Kansas. Cement Workers Morbidity Study

摘要

An industrial hygiene survey was conducted at the General Cement Company, Fredonia, Kansas as part of a study of the effects of materials found in Portland Cement facilities on the human respiratory system. At this facility the respirable and total dust levels for most of the individual jobs were below recommended exposure levels. There were four respirable dust samples which exceeded the 5mg/cubic m ACGIH recommended level for respirable nuisance particulate. Quartz exposure was noted primarily in the areas of the facility which are associated with raw materials. The authors recommend that surveillance monitoring be used on a periodic basis to assure that exposures remain within acceptable limits. The substitution of a vacuum system for the currently used brooms and shovels to clean up dust spills is also recommended. Personal protective equipment may be used by workers whenever engineering controls are not available or during maintenance, repair and clean up operations.
