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employer broke any rule; any findings appear as the citations listed below, and citations can be contested, reduced, or withdrawn.

Hazardous substances 9000

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:  On or about February 22, 2023, an employee was exposed to mixed respirable dust containing quartz and cristobalite at 70.775 ug/m3; Exposure calculations included a zero increment for 33 minutes not sampled. At this time employees are being exposed to levels of respirable quartz and cristobalite silica above the PEL.

Penalty
Initial $0 · Current $0

Hazardous substances 9000

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:   For the employee including, but not limited to, the employee whose exposure is described in Citation 1, Item 3(a):  On or about February 22, 2023, an employee was exposed to mixed respirable dust containing quartz and cristobalite at 70.775 ug/m3; Exposure calculations included a zero increment for 33 minutes not sampled. At this time, employees are being exposed to levels above the PEL and the employer shall require mandatory use of a respirator until feasible engineering controls can be put in place.  General methods of control applicable in this circumstance include, but are not limited to the following:  1) Re-evaluate the ventilation systems for ways to improve air movement/capture of the high levels of silica dust generated and to further ensure the most adequate removal of the silica dust from the worker exposure;  2) Re-evaluate the existing work practices to reduce the worker exposures to the airborne silica dust;   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 the respirable dust permissible exposure limits.
