PHR “Meet the Author!” Web Cast on Beryllium and OSHA Standards—February 4, 2008
On Monday, February 4, Public Health Reports will sponsor a “Meet the Author!” web cast titled “Beryllium: Why Do OSHA Standards Remain the Same, Even When the Science Changes?” Dr. Michaels, director of The Project on Scientific Knowledge and Public Policy and research professor and acting chairman of the Department of Environmental and Occupational Health at The George Washington University School of Public Health and Health Services, will discuss the devastating health effects of beryllium exposure and the subsequent industry versus science controversy that ensued.
Dr. Michaels recently wrote an article on the topic that appears in the January/February issue of Public Health Reports.
In a 1947 report, entitled Public Relations Problems in Connection with Occupational Diseases in the Beryllium Industry, the Atomic Energy Commission (AEC) asserted that the ability of the U.S. government to produce nuclear weapons was threatened by the high incidence of severe health effects associated with exposure to beryllium, a metal vital to weapons production. In response, the AEC established a workplace exposure limit which dramatically reduced beryllium disease incidence. This limit is known as the “taxicab standard” since it was determined by two AEC scientists working in the back seat of a taxi on their way to a meeting.
Over the next several decades, however, increasingly powerful evidence accumulated that Chronic Beryllium Disease (CBD), a progressive and irreversible inflammatory lung disease, was associated with exposure to levels below the “taxicab standard” and by the 1990s, scores of workers employed in the production of nuclear weapons had been diagnosed with CBD.
Attempting to prevent strengthened government regulation, and to avoid negative publicity that would discourage use of the metal, the beryllium industry waged a concerted effort over decades to counter the accumulating scientific evidence of beryllium’s toxicity. The industry relied on expert services provided by a major public relations company and a leading ‘product defense’ firm. Eventually, when the scientific evidence became so great that it was no longer credible to deny that workers developed CBD at levels permitted by an out-dated standard, the industry responded with a new rationale for delay: that more research was needed to determine the best standard.
The industry’s efforts have been, for the most part, successful. While each year brings new studies linking CBD with beryllium exposures below the current standard, the “taxicab standard” remains the limit enforced by the Occupational Safety and Health Administration in private sector workplaces. U.S. civilian nuclear weapons workers have greater protection than private sector workers; in 1999 the Department of Energy issued strengthened beryllium regulations, reducing the workplace exposure level that triggers protective action by a factor of 10.
The lessons from this case study for public health policymakers include:
The lack of CBD cases in the 1950s should not have been seen as proof the standard was adequate.
Industry scientists defended the “taxicab standard” long after it was correctly recognized as inadequate by independent scientists.
In particular, work by scientists employed by firms specializing in product defense and litigation support must be seen for what it is: advocacy, rather than science. This study illuminates the practice of “manufacturing uncertainty,” the strategy used by some polluters and manufacturers of hazardous products to prevent or delay regulation or victim compensation.
To best protect public health, we must consider the hazards associated with a toxic material through the entire life cycle of the product.
