Potential health hazards from exposure to heated process materials including chlorinated napthalenes, butyl rubbers, and polyethylene were investigated. The study was requested by the Dana Corporation (SIC-3592, SIC-8911, SIC-3070), Richmond, Indiana and was performed on October 23 and 24, 1980. Management was concerned about its Plastigage process, which used a thin strip of elastomer to gauge the clearance of bearings and related items. The Plastigage process involved three workers at two different sites. Process emissions samples and bulk samples of the materials used were analyzed. Process air samples showed the presence of the chlorinated naphthalenes; hexane, cyclohexane, alkenes, and methylcyclopentane. The breathing zone samples of one worker contained 3.0 milligrams per cubic meter of total chlorinated naphthalenes. This was the only measurement which approached the OSHA recommended exposure control limit of 2.0 to 5.0 milligrams per cubic meter depending upon the exact vapor mixture. The authors conclude that the airborne exposures were not hazardous, although deficiencies in the ventilation system and repeated hand contact with the product were identified as potentially hazardous. The lack of temperature limiters on the heating pots was also identified as potentially hazardous.
