Preliminary Analysis, Asbestos Personal Samples at Certain-Teed Corporation, Hillsboro, Texas

摘要

Asbestos (1332214) personal samples were analyzed at the Certain-Teed Corporation (SIC-3292) in St. Louis, Missouri, in July, 1969. Concentrations ranged from 0.1 fibers longer than 5 microns per cubic centimeter (microns/cc) in one sample from pipe forming to 7.0 fibers longer than 5 microns/cc in a warehouse sample. An accompanying letter notes that four measurements were in excess of the proposed Threshold Limit Value of 5 fibers longer than 5 microns/cc.
