Ohio firefighters responding to explosions and a fire at Toledo industrial recycling business

Explosions at Brent Industries, an industrial recycling business in Toledo, Ohio, killed two workers and sparked a large fire early Tuesday morning, according to officials. The blasts, which occurred during a shift change, were followed by flames and dark smoke billowing from the building. Fire crews discovered the bodies of a man and a woman inside the smoldering structure.

Two additional employees suffered minor injuries. No hazardous threat to the air was detected by monitors, and environmental officials confirmed there were no immediate indications as to the cause of the explosions. The federal Occupational Safety and Health Administration (OSHA) is currently investigating the incident, with a six-month timeframe for completion.

The company, based in Brent, Alabama, provides textile reconditioning and industrial recycling services. Brent Industries had previously experienced an explosion and fire at its Toledo plant in 2015, which resulted in one fatality. OSHA cited the company for multiple violations and fined it $27,000 in that incident.
