Video shows truck carrying highly reactive chemicals exploding in Denny’s parking lot

A truck carrying 2,300 gallons of diphenylmethane, a reactive spray foam chemical, exploded in the parking lot of a Denny’s restaurant in Spartanburg, South Carolina. The incident, caused by the chemical reacting with water, led to the restaurant’s closure, decontamination of four employees, and no reported injuries. The truck belonged to Patriot Environmental Services and was unrelated to Denny’s operations.
