Criteria for updating the crystalline silica pel
In April 2016, the Occupational Safety and Health Association (OSHA) passed new regulations for crystalline silica exposure limits in the workplace.
The regulations include a reduction in the permissible exposure limit (PEL) to 50 micrograms per cubic meter (µg/m.
Under the proposal, the new PEL for construction, maritime and general industries would be 50 µg/m, a point at which employers would be required to conduct exposure monitoring.
When exposure levels are greater than the PEL, employers must limit worker access to those exposure areas and use dust control methods.
