Jackson JMJ-20-78 January 19, 1978 r At* ^Hiss/py iany 0SftA ' Ll/97B Work area air samples for routine OSHA compliance have been completed. These samples were taken In October. Results are In Table I. I A visual Inspection of the handling procedure was made during the blending operation in the Celanex area. The following observations were made: A dust problem may exist where Decarbromodiphenyl oxide, PBT chips and Thermo Guard (antimony oxide) are added to the blend hopper. An excessive amount of airborne dust was also evident during the cleanup of the area after blend preparation was completed. This problem was caused by dry sweeping of the area. Plans are to monitor for airborne particulates in the Celanex blending area during the next routine asbestos sampling period. JMJ/mb Attachment cc: C. A. Amond - Bishop W. C. Beyer G. D. Boyd J. L.
