National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Industrial Hygiene Survey of California Cement Co., Colton, California. Cement Workers Morbidity Study.

PB94165081

Publication Date	1982
Personal Author	Sanderson, W. T.; Davidson, C.
Page Count	54
Abstract	A walk through survey was conducted of the California Cement Company, Colton, California, to determining the presence of materials harmful to the health of workers at that and similar sites. For most jobs at the site the respirable and total dust levels were below recommended limits. There were eight respirable dust samples which exceeded the 5.0mg/cu m recommended ACGIH levels for respirable nuisance particulate. Detectable levels of quartz (14808607) were found in 11 respirable dust samples. Six total dust samples exceeded the Mine Safety and Health Administration limit of 10mg/cu m. Exposure to quartz dust was associated with raw materials. The authors recommend that personal respirators should be provided for workers involved in maintenance and clean up operations. Substitution of a vacuum system for the currently used compressed air would greatly lessen the current exposure to dust during clean up operations. The use of disposable paper or cloth respirators is not suitable for protecting the worker from dust levels. The exposures to carbon-monoxide (630080) and nitrogen oxides can be reduced by turning off engines when not in use.
