Thomas Director of Environmental control Owens Corning Fiberglas Corporation F. 0. Box 901 Toledo, Ohio 43601 Re: Environmental Health Investigetion Owens corning Piberrlaa Corporation Berlin. N. J. Plant Studies on employee work environment were conducted at the Berlin, New Jersey Plant of Owens Corning Flberc.las Corporation September 23 throuv/h September 27, 1968. This punt processes initallation for flat surfaces and for pipes in various sizes and thicknesses, using asbestos, silica, diatomite and cement as main ingredients. The operation is known 33 the Kaylo process. Samples of work room air were collected to determine the concentration of asbestos dust3 and measurements were made of noise intensity at various octave band frequencies. EXHIBIT A dust exposure / U U for employees unloacinc, 00 cars of diatomite shipped in paper bays. The supplier should be urged to use a multi-wall paper bac of heavier strength and one with a dust proof seal. More care should be taken In the loading of box cars to prevent broken bags. There is potential dust exposure at the second floor batch mix area during bag dumping. It is recommended that the hopper where bags are dumped be enclosed on three sides and mechanically exhausted to the bag collectors. Hie handling of empty bags is a source of dust. It is suggested that empty bags be placed in a mocnanicaily exhausted bin. Oust counts in the area of the flatware line where the product is boxed or stacked on pallets are higher than ujsjrable. It is suggested that cartons to be loaded, travel on a roller conveyor that passes through a mechanically exhausted booth enclosure. The design of dust collection hoods on the integrated line sawing stations should be improved in order to provide more complete enclosure. Oust counts are excessive at these stations, and it is recommended that employees wear 2 - 1 j I ^ | ^ ! ' | ii'*piratory protection until environnental control has been installed. Dust control at the two band sawing stations for pipe needs improvement. Operators are exposed to high dust concentrations. The two band saw stations should have a separate dust collecting system rather than being "tied in" to one of the existing systems. Hood design for dust con trol should be improved. work environment around the entrance to the Sid cylinder is bound to be quite warm and to have high humidity due to escaping steam, ngineerinc studies should be made to en close an exhaust steam to the outdoors. . ,*n sir sample In the uowtherm boiler room shows that tiure is no exposure to Dowtherm. Measurements for noise throughout tne plant show a nuisance level of noise being created by the release of conpressed air without the benefit of muffles, a high noise level exists in front of tns Sid cylinder due to escaping steam. This noise source adds to the background -3 - ' noise level of nearby areas of the plant. Noise on the flatrare sanding linte is borderline and employees here should be monitored periodically with audiometrie testing* Undesirable noise levels e<ist on the integrated line sawing equipment, enclosure of the sound source with accoustical paneling is desirable. The Rotoblast equipment in the Mold Shop is noisy# but the main shop sound pressures e::ist in the lower octave band'frequencies. The problem is mainly one of nuisance sound intensity. frr n r ( Z y a ,-:' . i. villiam R.
