'!*he operation is known as the Kaylo process.

Oust counts in the area of the f -ware line where the product is boxed or stacked on pallets are higher than oesirable. It is suggested that cartons to t>e 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.

The two band saw st ions should have a separate dust collecting system rath than being "tied in to one of the existing systems. Hoo.. design for dust con trol should be improved. Kork environment around the entrance to the Sid Cylinder is bound to be quite warm and to have high humidity due to escaping steam. engineering studies should be made to en close an exhaust steam to the outdoors. .*n air sample in the bowtherm boiler room shows tnat th-ire is no exposure to bowtherm. Measurements for noise throw hc-ut tn plant show a nuisance level of noise being created by the release of compressed air without the benefit of muffles, a high noise level exists in front of tne Sid Cylinder due to escaping steam, this noise source ados to the background -3- noise level of nearby areas of the Noise* on the flatware sanding line is borderline a.-.d employees here t should be monitored periodically with audiometric testing. Undesirable noise levels evist <. . the integrated line sawing equipment, enclosure of the sound source with accoustlcal paneling is desirable. The Rotoblast equipment in the Mold Shop is noisy, but the main shop sound pressures e::lst in the lower octave band frequencies. The problem is mainly one of nuisance sound intensity. --r > < / / > (X /* Villiam R.
