A leaking kettle, a mistaken gasket swap, and an alarm system that never made a sound - those are the failures federal prosecutors say led to a deadly explosion at a Columbus paint plant, and now the company behind it has pleaded guilty in federal court. Yenkin-Majestic Paint Corporation admitted to negligent endangerment for the April 8, 2021 blast at its Columbus facility, which killed press room supervisor Wendell Light and severely injured several other workers.
Light, 44, was the sole fatality of the explosion, and his body was recovered from the facility's rubble roughly nine hours after the blast, according to a Columbus Division of Fire statement reported by 10TV. The explosion also caused extensive damage to the facility and nearby buildings, per the seed facts of the case detailed by the Tampa Free Press. Yenkin-Majestic used large steel vessels called kettles to heat raw materials during resin production, and the vessel at the center of the disaster, known as Kettle 3, had experienced previous high-pressure spikes before the explosion.
How a Leaking Manway Set the Stage
According to the case details, Yenkin-Majestic installed a new access door, called a manway, on Kettle 3 in December 2020. That newly installed manway began leaking almost immediately. Company personnel mistakenly believed the replacement gasket material was Teflon, when it was actually silicone, and the company attempted to fix the leak with a thicker gasket rather than addressing the underlying problem.
Instead of taking the leaking kettle offline, Yenkin-Majestic kept running it. The company never pressure-tested the newly fabricated manway before returning the vessel to service, and the improperly fitted manway and gasket ultimately failed under the pressure buildup that followed. Federal investigators say the incident was preventable through standard maintenance procedures.
The Midnight Restart That Triggered the Blast
Just before midnight, a Kettle 3 operator restarted the vessel's agitator without knowing it had stopped running, a stoppage investigators linked to electrical maintenance happening at the site that night. Restarting the agitator caused the resin mixture to rapidly vaporize and sharply increase internal pressure inside the kettle. The failed seal then vented hot liquid resin and flammable solvent vapors onto the plant floor and into neighboring work areas.
Facility gas sensors registered the rising combustible vapor levels as the cloud spread, but the monitoring system lacked any audible alarm trigger to warn workers. The U.S. Department of Justice noted that while sensors recorded rapidly increasing concentrations of flammable solvent vapor, the gas detection system was never wired to sound an alarm for personnel who might otherwise have evacuated. The spreading vapor cloud encountered an ignition source at 12:04 a.m. and detonated.
Federal Findings and the Road to a Guilty Plea
The criminal investigation drew on multiple agencies, including the EPA Special Investigations Unit, the Ohio EPA Special Investigations Unit, the Ohio Attorney General's Office Bureau of Criminal Investigation, and assistance from the Occupational Safety and Health Administration. That federal-state effort culminated in Yenkin-Majestic's guilty plea to negligent endangerment, according to the Department of Justice.
Assistant U.S. Attorneys Adam Cullman and David Twombly are leading the prosecution, with Cullman serving as senior trial attorney for the Environment and Natural Resources Division and the Southern District of Ohio. John Logue said the explosion demonstrated the importance of environmental safeguards and proper operating procedures, while Adam Gustafson said pressurized equipment can cause terrible accidents when safety protocols are not followed. Jeffrey A. Hall said companies using hazardous chemicals must prevent releases that endanger people, and Dominick S. Gerace II said companies must protect employees from workplace danger. Andy Wilson said Yenkin failed to keep its employees safe, resulting in one death and several injuries, and added that the plea provided a measure of accountability for Yenkin's failures. The EPA said it will hold accountable companies that put workers and the public at risk by ignoring safety and emergency procedures.
Earlier Regulatory and Scientific Findings
The guilty plea follows years of regulatory scrutiny. In October 2021, OSHA cited Yenkin-Majestic for two willful and 33 serious safety violations, proposing $709,960 in penalties and placing the company in its Severe Violator Enforcement Program after finding the company had altered equipment without proper engineering inspection, according to the agency's own news release. Two years later, reporting on the incident discussed inadequate safeguards, including interlocks intended to block solvent addition when the agitator was off, and said the plant had failed to pressure-test the newly fabricated 20-inch manway before placing it in service.
Chemical Safety Board incident data and legal reporting estimated total physical property damage from the explosion and the roughly 11-hour fire that followed exceeded $90 million, according to the Ammons Law Firm. Firefighters used an estimated 350,000 gallons of water to extinguish the blaze, and the incident raised potential environmental concerns because water could be contaminated with resin solution. The incident highlighted the risks of low-pressure vessel integrity in chemical manufacturing.
Questions About Property Claims
The explosion's aftermath reached well beyond the plant's walls. The blast caused extensive damage to the facility and nearby buildings.
According to Franklin County's 2025-2027 plan, CEPAC serves as the county's Local Emergency Planning Committee for hazardous-materials emergency preparedness.
Questions about the explosion's aftermath include how any property-damage claims might be handled. The available sources do not detail a corporate dissolution, divestitures, or the status of civil claims or neighbor restitution.
