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broke any rule; any findings appear as the citations listed below, and citations can be contested, reduced, or withdrawn.

Initial $10,000 · Current $7,000 Reduced
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:
a) Crane operators and other employees working in/around the converter
area were exposed to the hazard of explosions and/or fires resulting
from containers of wet scrap anodes being dumped into converter
vessels which contain molten copper matte. The investigation showed
that scrap anodes stored uncovered in the rain and/or taken directly
from the refinery rinse area were not allowed sufficient time to air
dry or they were dried mechanically with the available heat burners.
The employer allowed the wet scrap to be dumped into the converter
vessels. In doing so, the employer did not follow the company
operating procedures for the smelter cranes which prohibits such
dumping.
