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broke any rule; any findings appear as the citations listed below, and citations can be contested, reduced, or withdrawn.

employer did not
furnish to each of his employees employment and a place of employment
which were free
from recognized hazards that were causing or likely to cause death or

to employees in that employees were exposed to the hazard of being struck
by machinery and
equipment:
