29 CFR 1910.1053(g)(1):  Where respiratory protection was required by this section, the employer did not provide each employee an appropriate respirator that complied with the requirements of this paragraph and 29 CFR 1910.134:  (a) Grinding Area, booth #2; On or about August 10, 2023, an employee finishing castings through use of a grinder was exposed to respirable crystalline silica in excess of the PEL (8-hour TWA of 126.42 ug/m3).  Engineering and work practice controls that were implemented were not sufficient to reduce the employee's exposure to or below the PEL.  Particulate N95 respirators were utilized as respiratory protection and required elements of 29 CFR 1910.134 including, but not limited to, fit testing were not performed.
