In early 2001, an epidemiologist at the Occupational Safety and Health Administration sought to publish a special bulletin warning dental technicians that they could be exposed to dangerous beryllium alloys while grinding fillings. Health studies showed that even a single day's exposure at the agency's permitted level could lead to incurable lung disease.
After the bulletin was drafted, political appointees at the agency gave a copy to a lobbying firm hired by the country's principal beryllium manufacturer, according to internal OSHA documents. The epidemiologist, Peter Infante, incorporated what he considered reasonable changes requested by the company and won approval from key directorates, but he bristled when the private firm complained again.
"In my 24 years at the Agency, I have never experienced such indecision and delay," Infante wrote in an e-mail to the agency's director of standards in March 2002. Eventually, top OSHA officials decided, over what Infante described in an e-mail to his boss as opposition from "the entire OSHA staff working on beryllium issues," to publish the bulletin with a footnote challenging a key recommendation the firm opposed.
