A commercial hazardous materials tanker truck carrying approximately 2,300 gallons of diphenylmethane exploded in a Denny’s restaurant parking lot along Reidville Road in Spartanburg County, South Carolina. The explosion prompted an immediate quarantine of the commercial structure and an extensive response from regional hazardous materials teams. The vehicle, owned and operated by Patriot Environmental Services, was returning from a field service assignment when the incident occurred.Prior to the blast, the operator of the truck experienced mechanical and chemical inflation issues while driving. The driver pulled off the active roadway and entered the restaurant parking lot to inspect the vessel. According to corporate statements from Denny's management, the transport vehicle was entirely unrelated to the restaurant's operational supply chain or business activities. Representatives from Patriot Environmental Services reported that the chemical compound collected during their field service job was highly water-reactive. Moisture contamination inside the tank initiated an uncontrolled chemical expansion, significantly building internal pressure.Eyewitnesses captured video footage of the tanker venting heavily from its upper seals moments before the tank structurally failed and erupted. The forceful burst sprayed expanding spray-foam compounds across the entirety of the parking lot, nearby vehicles, and the exterior walls of the restaurant infrastructure. The Spartanburg County Hazardous Materials Team arrived on the scene alongside local fire departments to identify the compound and contain the environmental residue.Emergency crews established a strict hazardous material perimeter, isolating the building. First responders initiated emergency decontamination protocols for four Denny’s restaurant employees who were exposed to the chemical spray at the scene. While the environmental spill resulted in substantial property impacts and localized pollution, no immediate injuries or civilian casualties were reported following the blast.The Spartanburg County Sheriff's Office closed adjacent segments of the roadway, rerouting heavy traffic away from Reidville Road and South Blackstock Road. The restaurant remains indefinitely closed under a mandatory environmental quarantine as specialized cleanup crews scrape the chemical product from the facility's walls and surrounding asphalt. Multiple state and local environmental agencies continue to investigate the mechanical failures and loading procedures that led to the accidental water introduction.
