On Monday afternoon, a large explosion rocked a metal manufacturing plant just east of Cleveland, Ohio, sparking a fire and sending a massive column of black smoke into the sky. 

Fox News said the explosion occurred at I Schumann & Co. metal plant in Bedford. The company produces metal alloys. 

The black smoke billowing into the sky is reminiscent of the East Palestine controlled burn of toxic chemicals earlier this month. Law enforcement in Bedford has yet to say if the smoke is toxic to surrounding communities. 

Here's another video of the fire. 

Emergency services have requested several medical helicopters. There are reports this could be a 'mass casualty incident.' 

The cause of the blast is unknown at this time.
