Chemical leak at Catalyst Refiners in Institute kills two, injures 19
Two dead and 19 hospitalized after a chemical leak at Catalyst Refiners in Institute, West Virginia, following a violent reaction involving nitric acid.
A chemical leak at the Catalyst Refiners facility in Institute, West Virginia, left two people dead and 19 others hospitalized on Wednesday, officials said. The incident, described by emergency managers as a violent chemical reaction, occurred while workers were preparing to shut down part of the plant. Local authorities reported the release involved nitric acid reacting with another substance, producing an immediate and intense response at the scene.
Two fatalities and initial casualty figures confirmed
C.W. Seigman, director of emergency management for Kanawha County, confirmed two deaths linked to the incident during a briefing with reporters. He said 19 people were taken to hospitals, including several first responders who were exposed while attending to the scene. The identities of the deceased have not been released pending family notification and further investigation.
Details of the reaction and substances involved
Emergency officials said the release followed a chemical reaction that involved nitric acid and an additional unspecified chemical. Seigman described the event as an “overactive reaction” that occurred quickly as crews were preparing to isolate part of the facility. Investigators on site are collecting samples and documenting the area to determine the precise sequence of events that led to the leak.
Emergency response and first responder injuries
Among those hospitalized, seven were EMS personnel who responded to the initial report, according to officials. Ambulance crews, firefighters and hazmat teams were dispatched immediately and worked to evacuate and decontaminate affected workers and bystanders. Local hospitals reported receiving multiple patients, and some injured people were transported in private vehicles and, in one instance, a garbage truck, underscoring the chaotic conditions during the early stages of the response.
Operations halted as plant sections were shut down
Catalyst Refiners personnel were reportedly preparing to shut down at least part of the plant when the reaction occurred, an action that may have been part of routine maintenance or an emergency isolation procedure. Company representatives have not yet issued a detailed public statement clarifying the operational status or the precise activities under way at the time. Regulators and company safety teams are coordinating to secure the facility and establish when normal operations can resume.
Local impact and community precautions
Residents and businesses in the immediate vicinity were warned to stay clear of the area while responders contained the release and monitored air quality. Emergency officials advised anyone experiencing respiratory irritation or other symptoms to seek medical attention promptly. Schools and workplaces nearby were placed on alert as monitoring continued; authorities emphasized that residents follow official guidance and avoid unverified sources of information.
Pending investigations by state and federal agencies
State environmental and occupational safety authorities are expected to join local investigators to determine regulatory compliance and potential cause. Samples from the plant and the surrounding environment will be analyzed for contamination and exposure risks. Depending on the findings, federal agencies such as the Environmental Protection Agency or the Occupational Safety and Health Administration may open formal inquiries to assess whether safety protocols were followed.
Emergency teams said the priority is ensuring public safety, treating patients and securing the site for a thorough technical investigation. Company internal investigators will likely collaborate with outside experts to reconstruct the event and recommend corrective measures. Officials cautioned that drawing firm conclusions before laboratory results and complete incident reports are available would be premature.
The spill and reaction at Catalyst Refiners have raised renewed attention to chemical safety at industrial facilities, particularly involving strong oxidizers like nitric acid. Community leaders and safety advocates said they will press for transparency from the company and regulators as more information emerges. Authorities urged patience as investigators gather evidence and provide updates to the public.
Emergency managers reiterated that anyone with information about the incident or those who were in the area at the time should contact Kanawha County emergency services to assist with the inquiry. Officials said they will release additional details, including the identities of the deceased and the conditions of the hospitalized, once families have been notified and medical evaluations are complete.
The focus now remains on patient care, hazard containment and a thorough, methodical investigation to prevent recurrence and protect the surrounding community.
