The proposed standard, which will apply to clinical, industrial, and academic labs, has two basic thrusts: 1) Continued compliance with the existing permissible exposure limits
(PELs) for OSHA-regulated substances, including both an eight-hour time-weighted average and any ceiling value or acceptable ceiling concentration as measures of air contamination.
The occupational permissible exposure limit
(PEL) for hexavalent chromium had been set at 52 [micro]g/[m.
The administration classifies wood dust as a "nuisnce dust" and a permissible exposure limit
of 15 mg/[m.
There's no attempt to raise the permissible exposure limit
of the rule itself," Lauriski said.
The calculated permissible exposure limit
(CPEL) for dusts containing silica was established at 0.
Any employer who has a workplace covered by the standard must assess whether any employee may be exposed to lead at levels exceeding the permissible exposure limit
(PEL) of 50 micrograms per cubic meter of air averaged over an eight-hour period.
Occupational Safety & Health Administration (OSHA) finalized a new regulatory structure for the control of crystalline silica, including significantly reducing the silica permissible exposure limit
(PEL) and action level.
In addition to lowering the crystalline permissible exposure limit
(PEL) to 50 [micro]g/[m.
The good news is that we don't see MSHA acting to strengthen its existing diesel rule, although there is a distant possibility the agency will try and reduce the permissible exposure limit
under cover of extending its regulation to surface operations, something organized labor has sought since the beginning.
The National Institute for Occupational Safety and Health (NIOSH) has found DWAs not comparable to the lapel sampling method used by OSHA to determine compliance with its permissible exposure limit
(PEL) or other 8-hr occupational exposure limits (OELs) (Donaldson and Stringer 1976).
During the formal rulemaking process, AFS presented substantial evidence that OSHA's proposed permissible exposure limit
(PEL) was technologically and economically infeasible for U.
