• Description:
  In response to a request from the International Chemical Workers Union, Locals 619 and 959, an evaluation was made of possible hazardous working conditions at Kawecki Berylco Industries, Inc., Boyertown, Pennsylvania. Concern was voiced over exposures to titanium-diboride (12045635) (TiB2), which was produced at this facility, carbon-black (1333864), and polynuclear aromatic hydrocarbons (PNAs). The process involves the blending of titanium- dioxide (13463677), boron-carbide (12069328) and carbon-black. Following vacuum sintering, the product, TiB2, was powered through jaw crushing, screening, ball milling, and fine grinding. Analysis of the carbon-black revealed that it had an excessive content of cyclohexane extractables, suggesting that it was contaminated with PNAs. There was also a high total dust exposure at this facility. The author concludes that a potential hazard exists of exposure to carbon-black containing polynuclear aromatics. The author recommends that better exhaust ventilation measures be designed
  
  that the water blending activity be automated, thus reducing contact time with carbon-black
  
  that respiratory protective devices be used which are considered acceptable for this task
  
  and that hygiene facilities be adequate.
