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broke any rule; any findings appear as the citations listed below, and citations can be contested, reduced, or withdrawn.

Section 5(a)(1) of the Occupational Safety and Health Act of 1970:  The
employer did not
furnish employment and a place of employment which were free from
recognized hazards that
were causing or likely to cause death or serious physical harm to
employees in that employees
were exposed to molten metal explosions:
(a) Employees at the #1 furnace were exposed to serious molten metal burns
caused by charging whole bales (briquettes) of scrap aluminum which
contained
materials with internal cavities, and/or moisture/liquid and the bales
were not
separated, inspected, dried and sorted before charging into the furnace.
Among other methods, one feasible and acceptable abatement method to
correct
this hazard is to implement, maintain and ensure that a furnace charging
procedure prevents charging of scrap aluminum with internal cavities,
moisture,
liquids, and contaminants.  In addition, a preheating/drying procedure,
inspection
and scrap segregation policy must be implemented to prevent future furnace
explosions.
The employer was previously cited for a violation of this Occupational
Safety and Health
Administration standard which was contained in the Citation number 1, Item
number 1a,
with an issuance date of June 27, 1996.
