OSHA has delayed the effective date of its rule to lower beryllium exposure limits for a second time, to May 20, 2017. The agency said in a statement that the change will allow for “additional review into questions of law and policy.”
The new standard limits exposure to 0.2 micrograms of beryllium per cubic meter of air over an eight-hour period and 2.0 micrograms of beryllium per cubic meter of air over a 15-minute period.
