This tool is essential to ensure the safety of your employees while checking that you are conform with the new OHSA regulation. The new regulations apply to all employers with employees exposed to RCS above 25 μg/m3 under any foreseeable conditions. The new 50 μg/m3 PEL is half of the current 100 μg/m3 PEL from prior regulations but twice as permitting as the 25 μg/m3 PEL previously proposed by OSHA.
