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.

Abstract	Worker exposures to beryllium (7440417) (Be) were surveyed in an industrywide study of four Be facilities in 1968 through 1970 and 1971 thru 1972. In the 1968 survey, general area, gross, and respirable dust samples were collected. In 1970, mainly personal respirable samples were collected and some general area gross and respirable dust samples were analyzed. In the 1971 through 72 surveys personal respirable, personal gross, and the Atomic Energy Commission (AEC) sampling methods were used. In facility A, Be concentrations ranged from 0.08 to 166.8 micrograms per cubic meter (cu m) in the 1968 and 1970 surveys. In the 1971 and 1972 surveys, concentrations ranged from 0.13 to 76.4 micrograms/cu m. In facility B during the 1968 through 70 survey concentrations ranged from 0.01 to 1.29 micrograms/cu m. In facility C during the 1968 and 1970 surveys, concentrations ranged from 0.1 to 237.0 micrograms/cu m. In facility C the 1971-72 Pennsylvania State survey concentrations ranged from 0. to 582.0 micrograms cu m and during the NIOSH concurrent survey, concentrations ranged from 0 to 1146.0 micrograms/cu m in facility C. In facility D during 1968 and 1970, concentrations ranged from 0.1 to 136.0 micrograms/cu m and in 1971 through 1972 concentrations ranged from 0.1 to 136.0 micrograms/cu m. The author concludes that in facility A, Be concentrations by AEC methods generally were within the 2 microgram/cu m standard. Facility C exceeded the OSHA standard regardless of the sampling method used. It is feasible to operate Be facilities at the specified exposure standards.
