Criteria for updating the crystalline silica pel
Generally, exposure to silica can be limited by using water to minimize dust or by using a ventilation system to catch dust. “This is not rocket science and it’s not cost prohibitive,” Perez said. On April 19, 2017, the Department of Industrial Relations for the State of California issued an important update to Cal/OSHA’s new Respirable Crystalline Silica Standard for Construction.The standard is substantially similar to Federal OSHA’s new rules for silica.Employers in California must keep in mind that they are still subject to Cal/OSHA’s new permissible exposure limit for respirable crystalline silica of 0.05 milligrams per cubic meter (0.05 mg/M3), found in Title 8 section 5155, Table AC-1, which went into effect on October 17, 2016.In addition, employers must continue to comply with the requirements set forth under Title 8 section 1530.1 to control employee exposures to dust created by operations conducted on concrete or masonry materials.
Proponents for stricter regulations struggled for decades to improve the safety of workers in proximity of respirable crystalline silica.
The new standards will take effect on 23 June, after which industries have one to five years to comply with most of the requirements.
