In response to a request from a representative of the Oil Chemical and Atomic Workers International Union, NIOSH conducted an evaluation of possible hazardous working conditions at the Neville Chemical Company, Anaheim, California. Concern had been express about a carbon resin manufacturing process and two cases of liver disease in workers. This company manufactured petroleum resins by polymerizing organic molecules 5 to 12 carbon atoms in size using both a catalytic and a thermal polymerization process. Raw materials consist of cracked petroleum fractions, containing a wide variety of aliphatic and aromatic hydrocarbons. Most of the data gathered concerning the health of the workers indicated they were in good physical condition and that the causes of those deaths which had been reported had been misrepresented. Three major areas of concern did arise on inspection of the current working conditions. First was a need for an improved method to be used in the periodic cleaning of the clay filter towers. Secondly, there was excessive exposure to boron-trifluoride (7637072) in the treater facility. The third problem involved resin dust exposures working as a packager in the warehouse, particularly when the ventilation system was not functioning properly. Even though the dust levels in this area were below the limits for a nuisance dust, it was not clear whether the resin dusts would constitute a hazard.
