Text For Citation: 01 Item/Group: 001B Hazard:

29 CFR 1910.1053(f)(1):The employer did not use engineering and work practice controls to reduce and maintain employee exposure to respirable crystalline silica to or below the PEL, unless the employer can demonstrate that such controls are not feasible: Mansfield Plumbing Products, LLC. located at 150 East First Street in Perrysville, Ohio: On or about November 3, 2022 the employer did not implement adequate engineering or work practice controls to reduce and maintain employee exposure to respirable crystalline silica to or below the permissible exposure limit. Employees loading the kilns were exposed to hazards associated with exposure to crystalline silica dust above the permissible exposure limit such as, but not limited to, cough, fatigue, chest pain, and silicosis. Instance A On or about November 3, 2022 an employee loading the kiln was exposed to an 8-hour time weighted average (TWA) of 129.5 ?g/m3 for respirable crystalline silica dust, approximately 2.5 times the permissible exposure limit (PEL) of 50 ?g/m3. The exposure level was derived from a sample collected over 463-minute sampling period, with zero exposure assumed for the unsampled period of seventeen minutes. Instance B On or about November 3, 2022 an employee loading the kiln was exposed to an 8-hour time weighted average (TWA) of 148.17 ?g/m3 for respirable crystalline silica dust, approximately three times the permissible exposure limit (PEL) of 50 ?g/m3. The exposure level was derived from a sample collected over 453-minute sampling period, with zero exposure assumed for the unsampled period of twenty-seven minutes.
