Chemical Leak at West Virginia Silver Recovery Plant Kills 2, Sends 30 to Hospitals
Why It Matters
A deadly industrial chemical accident at a West Virginia plant has claimed two lives and strained regional emergency response systems, raising urgent questions about workplace chemical safety protocols and the risks facing industrial workers and first responders in the state’s historic “chemical valley.”
The incident unfolded Wednesday at the Catalyst Refiners plant in Institute, a community roughly 10 miles west of Charleston, and prompted a large-scale emergency response involving multiple hospitals, a shelter-in-place order, and a federal investigation.
What Happened
A chemical gas reaction at the Catalyst Refiners facility killed two people and sent approximately 30 others to area hospitals on Wednesday, April 22, 2026, according to authorities. The plant, owned by Ames Goldsmith Corp., specializes in recovering silver from industrial chemical processes.
Kanawha County Commission Emergency Management Director C.W. Sigman said the leak occurred as workers were preparing to shut down at least part of the facility. The reaction involved nitric acid and another substance during what is believed to have been a cleaning process, producing toxic hydrogen sulfide gas.
“Starting or ending a chemical reaction are the most dangerous times,” Sigman said at a news briefing, adding that “a violent reaction of the chemicals” caused the gas to instantaneously overreact. Officials confirmed that all deaths occurred on the plant site.
Among those hospitalized were seven ambulance workers who were responding to the initial leak. Other victims were transported to hospitals in private vehicles — and in at least one case, a garbage truck.
A shelter-in-place order was issued for the surrounding area and remained in effect for more than five hours before being lifted. Officials said local air quality and the water supply were believed to be unaffected.
By the Numbers
2 people killed, both on the plant site
~30 people transported to hospitals, including one in serious condition
7 of the hospitalized were first responders — ambulance workers who arrived to assist
12 patients treated at WVU Medicine Thomas Memorial Hospital in South Charleston, eight of whom arrived by personal vehicle
6 months — the timeframe OSHA has to complete its federal investigation into the incident
Response on the Ground
West Virginia Governor Patrick Morrisey praised first responders who rushed toward the danger at the Catalyst Refiners site. “We know that the first responders, they always run to the fire. They put themselves in harm’s way,” Morrisey said at an evening news conference. “We’re very grateful to these brave men and women and what they do.”
Vandalia Health Charleston Area Medical Center treated multiple patients brought by ambulance, while community members also arrived voluntarily seeking evaluation. Hospital spokesman Dale Witte said patients reported respiratory symptoms including cough, shortness of breath, sore throat, and itchy eyes. WVU Medicine Thomas Memorial Hospital reported that injuries among the dozen patients it treated were not considered life-threatening.
The leak required a large-scale decontamination operation in which affected individuals were required to remove their clothing and be sprayed down before receiving further care.
Ames Goldsmith Corp. President Frank Barber issued a statement acknowledging the tragedy. “This is an unfathomably difficult time,” Barber said. “Our thoughts and prayers are with our colleagues and their families.” The company pledged to cooperate fully with local, state, and federal investigators.
Zoom Out
The Institute area sits within West Virginia’s historically industrial “chemical valley” along the Kanawha River, a corridor that once housed dozens of large chemical manufacturing plants. Many of those facilities have since closed or changed hands, but industrial risk remains a concern for communities in the region.
The incident echoes broader national concerns about chemical plant safety, particularly in communities where aging infrastructure and complex industrial processes intersect with residential populations. Industrial accidents at chemical facilities have previously exposed gaps in emergency preparedness, especially for smaller or volunteer-based emergency response teams that may lack specialized hazmat training.
West Virginia has also faced ongoing challenges managing its industrial legacy while addressing broader infrastructure needs. State lawmakers have recently grappled with competing priorities, including economic development and public safety investment, as the legislative session has drawn to a close.
What’s Next
The federal Occupational Safety and Health Administration (OSHA) has opened a formal investigation into the chemical leak and has up to six months to complete its findings. State and local officials are also expected to conduct their own review of the incident.
Ames Goldsmith Corp. said it will cooperate with all investigative authorities. The long-term status of operations at the Catalyst Refiners plant in Institute has not yet been determined pending the outcome of those investigations.
