The Bush administration is trying to push through a new workplace safety rule to weaken workers’ protections against toxic chemicals before Bush’s term ends, according to The Washington Post. The rule, which has not been made public, would mandate a reevaluation of the methods used to measure risks to workers from toxic exposure in the workplace. The rule would also require the U.S. Department of Labor to entertain additional challenges to its risk assessments before establishing new limits on exposure to chemicals. So far, work on the proposal has reportedly been fast-tracked and has been conducted largely in secret, drawing sharp criticism from worker advocates. “This is a guarantee to keep any more worker safety regulation from ever coming out of [the U.S. Occupational Safety and Health Administration],” said workplace safety professor David Michaels. “This is being done in secrecy, to be sprung before President Bush leaves office, to cripple the next administration,” he said. Once it’s published, the rule will be open to public comment for 30 days.
