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employer broke any rule; any findings appear as the citations listed below, and citations can be contested, reduced, or withdrawn.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 micrograms per cubic meter, calculated as an 8-hour TWA:   a.  Dry Side Premix Line - On or about 12/05/2024, an employee manually placing bags onto fill pipes was exposed to airborne concentration of respirable crystalline silica at an 8-hour, time-weighted average of 51 micrograms per cubic meter of air, approximately 1.02 times the permissible exposure limit of 50 micrograms per cubic meter of air.   b.) Dry Side - On or about 12/05/2024, an employee operating a forklift was exposed to airborne concentration of respirable crystalline silica at an 8-hour, time-weighted average of 59 micrograms per cubic meter of air, approximately 1.18 times the permissible exposure limit of 50 micrograms per cubic meter of air.
