E. Keuper, Construction Division Safety Superintendent, the engineering standards and specifications have been reviewed and It has basn determined that all brands of asbestos listca m the engineering atlft~ ^~dai'ds~anTTpicl?rcatibns do*hot*contain erocldollte fibers. J. H." AilAh, Engineering' Department ESb, has"eoof3Tnated this review made by the Engineering Department and the Purchasing Department. They have found that most of the manufacturers are able to provide information showing the fiber type and percentage. This study also revealed that the North American Asbestos Corporation used a considerable amount of erocldollte fibers In many of their products. The respiratory protection specified by X. E. Keuper In his memorandum on dust control dated April 5, 1968, is capable of filtering out particles down to a size of three microns. The specified respiratory is a modeled Dustfoe" 'll with filter No. BM 21 B-97 manufactured by the Mine Safety Appliance Company. The Construction Division plans to initiate the monitoring of dust at 21 construction sites within the next month, mesa sites will include Beaumont, Victoria, and Houston. In the event anyone wishes to observe sampling at Beaumont, Mr. Xeuper would appreciate being contacted prior to the visitation as personnel at the site have been trained only In sampling and do not have a good background to discuss the program.
