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broke any rule; any findings appear as the citations listed below, and citations can be contested, reduced, or withdrawn.
