OSHA seeks to reduce exposure to highly useful, highly toxic metal
The metal beryllium is an engineer’s dream: Lightweight yet strong, capable of handling harsh environments underwater and out in space.
It’s also a medical nightmare. Minute amounts of its dust and fumes can trigger a disabling, sometimes deadly lung disease. It can cause cancer, too.
The Occupational Safety and Health Administration said it will propose Thursday to sharply tighten the level of beryllium to which workers can be legally exposed, belatedly responding to decades of studies showing that the current OSHA limit does not protect people’s lungs.
“This proposal will save lives and help thousands of workers stay healthy and be more productive on the job,” Labor Secretary Thomas E. Perez said in a statement.
This is OSHA’s second attempt at a tougher beryllium standard. It proposed one in 1975, only to see it beaten back by the secretaries of energy and defense. Beryllium is a critical component in nuclear weapons, and both agencies argued at the time that the country’s national defense could be compromised by lowering exposures.
But the U.S. Department of Energy, which oversees the nation’s nuclear-weapons facilities, had a change of heart years ago. In 1999, it approved rules to require respirator use for its workers and its contractors’ employees when beryllium levels reached 0.2 micrograms per cubic meter of air — one-tenth of OSHA’s current limit, and less than the scrapped 1970s proposal, too.
OSHA’s newly proposed standard, which would apply to an estimated 35,000 workers in a variety of industries, would reduce the current 2-microgram limit for an eight-hour exposure to 0.2 micrograms. It would also mandate medical exams for exposed workers and set down other requirements.
Nearly 100 deaths and 50 serious illnesses could be prevented each year if the rule takes effect, OSHA said. Besides lung cancer, exposed workers risk getting lung-scarring chronic beryllium disease, which is triggered by an allergic reaction to the metal and can kill.
The country has compensated nearly 2,500 current or former nuclear weapons workers who developed chronic beryllium disease, according to OSHA. But the full toll is unclear; beryllium has also been used in products ranging from space telescopes to golf clubs to dental appliances. OSHA believes that about 245 people are diagnosed with chronic beryllium disease each year.
As far back as 1999, as the Energy Department was finalizing its rule, OSHA said it would update its beryllium requirements. Petitions that year and in 2001 from groups such as Public Citizen and the Paper, Allied-Industrial, Chemical and Energy Workers International Union urged speedy action. The delays since then are typical for OSHA, which blames long waits for health standards on the process imposed by Congress.
The requirements for issuing a single standard are “onerous and burdensome,” OSHA chief David Michaels said in an interview. Michaels said OSHA had completed some work on the beryllium proposal when he arrived in late 2009, and has prioritized it since then, but only recently cleared the final hurdles.
