OSH ACT of 1970 Section (5)(a)(1): 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 combustible metal dust deflagration, explosion, and fire hazards while working near an indoor enclosureless dust collector used to collect fugitive dust emissions from screening and mixing equipment. (a) On February 3, 2025, in the Cladding Room, employees were engaged in the process of manufacturing thermal spray and brazing application product PAC912 (containing 5-9% combustible aluminum powder as an ingredient). The manufacturing process utilized an indoor enclosureless dust collector to collect fugitive dust emissions from screening and mixing equipment. The indoor enclosureless dust collector presented combustible metal dust deflagration, explosion, and fire hazards in that oxygen, fuel, suspension, and ignition sources were capable of being present at the same time within the system.
