OSHA's new crystalline silica rule was finalized March 24. It reduced the permissible exposure limit (PEL) to silica in half, from 100 µg (micrograms)/cu.m to 50 µg/cu.m. Here is what you need to know about the rule. AFS is committed to assisting foundries in coming into, and maintaining compliance with these new regulations, in the most effective and economical manner.
