The OSHA rule for silica in construction became effective September 23, 2017 although OSHA included a 30-day “grace period” for full enforcement. SMACNA members affected by this rule are encouraged to take a “holistic” approach to silica compliance by assessing the tasks and processes where silica (found in concrete) is disturbed (cut, drilled, grinded, etc.). SMACNA members should be aware that “Table One” and dust collection tools are not the only options for compliance.
