What this inspection record means

OSHA opens inspections for many reasons — routine scheduling under a national or local emphasis program, an employee complaint or referral, or a follow-up after a reported injury. Opening or conducting an inspection is not itself an allegation or a finding that this employer broke any rule; any findings appear as the citations listed below, and citations can be contested, reduced, or withdrawn.

29 CFR 1910.1053(c): The employer did not ensure that no employee was exposed to an airborne concentration of respirable crystalline silica in excess of 50 ug/m3, calculated as an 8-hour TWA.   a)     Pentair Flow Technologies, LLC is located at 1101 Myers Parkway, Ashland, OH; On or about February 13, 2020, at the production facility, an employee working in the knockout (Mash Room) production area was exposed to crystalline silica levels of 145.86 micrograms/ cubic meter which exceeds the permissible exposure limit PEL of 50 ug/m3. The sampling was performed for 417 minutes, and zero exposure was assumed for unsampled time.   b)     Pentair Flow Technologies, LLC located at 1101 Myers Parkway, Ashland, OH; On or about February 13, 2020, at the production facility, an employee working in the knockout (Mash Room) production area was exposed to crystalline silica levels of 139.01 micrograms/ cubic meter which exceeds the permissible exposure limit PEL of 50 ug/m3. The sampling was performed for 428 minutes, and zero exposure was assumed for unsampled time.

Hazardous substances 9010

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.   a)     Pentair Flow Technologies, LLC is located at 1101 Myers Parkway, Ashland, OH. On or about February 13, 2020, at the production facility, employees working in the knock-out (Mash Room) production area were over-exposed to respirable crystalline silica after several engineering and/or work practice controls used by the employer were not effective to adequately reduce silica exposures below the PEL. Employees were wearing the appropriate tight fitting respirators while conducting their daily tasks.   Multi-step abatement     Step 1:  Effective respiratory protection shall be provided and used by exposed employees as an interim protective measure until feasible engineering and/or administrative controls can be implemented, or whenever such controls fail to reduce employee exposure to within permissible exposure limits.    Step 2:  Submit to the Area Director a written, detailed plan of abatement outlining a schedule for the implementation of engineering and/or administrative measures to control employee exposure to hazardous substances as referenced in this citation.  This plan shall include, at a minimum, target dates for the following actions which must be consistent with the abatement dates required by this citation:    1.     Evaluation of engineering/administrative control options; 2.     Selection of optimum control methods and completion of design; 3.     Procurement, installation and operation of selected control measures; 4.     Testing and acceptance or modification/redesign of controls.    Step 3:  Abatement shall have been completed by the implementation of feasible engineering controls and/or administrative controls upon verification of their effectiveness in achieving compliance.    Feasible engineering controls include, but are not limited to: 1.     Provide local ventilation to limit exposure to hazardous or toxic agents and environments within acceptable limits; the system shall be inspected periodically. 2.     Portable engineering control devices shall be used at the location to collect the air borne respirable crystalline silica, i.e., local HEPA filtered ventilation systems.     Date by which Step 1 must be abated:   /   /     Date by which Step 2 must be abated:   /   /    Date by which Step 3 must be abated:   /   /
