OSHA Administrator David Michaels unveiled the program in a teleconference Oct. 9, saying the agency seeks to open a dialogue about reducing workplace chemical levels. The agency followed this the next day with a request for information in the Federal Register providing details of the program and initiating a 180-day comment period.
There are tens of thousands of airborne substances in U.S. workplaces, Michaels said during the teleconference. But only about 500 have permissible exposure limits set by OSHA, and most of those are dangerously out of date, he said.
OSHA's past efforts to update its PELs have been largely unsuccessful, with only about 30 updates and one new standard since 2000, according to Michaels.
“Many workers are being exposed to levels of toxic substances that are legal but not safe,” he said. “This new dialogue will show the world what we can do to protect our most valuable resource—our workers.”
Among the approaches OSHA wants to consider are “control bonding” and “hazard bonding,” which group chemicals according to their properties and control them using the same methods, according to Michaels.
“We have to assess the feasibility of these approaches, and that can take years,” he said. “There's got to be a better way to approach this issue. If we do it chemical by chemical, it could take centuries.”
