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broke any rule; any findings appear as the citations listed below, and citations can be contested, reduced, or withdrawn.

No citations on file for this inspection, so there is no finding of any violation on this record. An inspection can be open and still ongoing, or closed with no violations at all; OSHA's citation feed is also backfilled in rolling windows, so citation rows for a very recent inspection may not have been ingested yet.

This record is reproduced from the U.S. Department of Labor Open Data API (OSHA inspection dataset). OSHA publishes its own view of this case as inspection number 316208594.
