Hyoungwon E&C America Inc. — Worker Killed by Nitrogen Gas at Solar Panel Factory (2025)
Outcome: A worker employed by Hyoungwon E&C America Inc. died from nitrogen gas asphyxiation during construction work at Hanwha Q Cells Georgia Inc.'s White, Georgia solar panel manufacturing plant; OSHA cited two serious violations and proposed $20,522 in penalties for failure to protect workers from nitrogen hazards and failure to train workers on oxygen-deficient atmospheres.
Hyoungwon E&C America Inc., an engineering and construction contractor, was performing work at the Hanwha Q Cells Georgia Inc. solar panel manufacturing plant in White, Georgia when a worker was exposed to nitrogen gas and died from asphyxiation. Nitrogen gas, which is used in many industrial processes as an inert blanketing agent, displaces oxygen from enclosed areas and can create oxygen-deficient atmospheres that kill without visible warning.
OSHA cited the company for two serious violations: failure to protect employees against asphyxiation hazards from nitrogen gas, and inadequate information and training provided to workers regarding nitrogen gas hazards and the risks of oxygen-deficient atmospheres. OSHA proposed $20,522 in penalties.

How Crucible Prevents This
Nitrogen gas is an asphyxiating gas that displaces oxygen without warning — workers lose consciousness rapidly with no sensory indicator of danger. Construction contractors working at industrial facilities where nitrogen is used for purging, blanketing, or cooling operations must receive specific hazard communication about oxygen-deficient atmospheres. A Crucible pre-work session gate requiring documented review of facility-specific atmospheric hazard profiles and confirmed worker training on nitrogen asphyxiation risk before any work begins inside industrial process areas would have addressed the training gap cited here.
