Catalyst Refiners Chemical Leak in Institute, West Virginia

On the morning of April 22, 2026, a violent chemical reaction tore through a building at the Catalyst Refiners plant in Institute, West Virginia, killing two workers, leaving one person in critical condition, and sending approximately 30 others to area hospitals. Among the injured were seven emergency responders who rushed to the scene and were themselves exposed to the toxic gas release.

The incident has shaken the Kanawha Valley community and raised serious questions about workplace safety, chemical handling procedures, and corporate accountability. Investigations are now underway at both the state and federal level, including reviews by OSHA and the National Chemical Safety Board.

If you or a family member were injured in this incident, or if you lost a loved one, you may have significant legal rights. The Lyon Firm is actively monitoring this case and is available to speak with affected individuals and families at no cost.

WHAT HAPPENED AT CATALYST REFINERS

Catalyst Refiners, Inc. is a chemical manufacturing subsidiary of Ames Goldsmith Corporation, a precious metals company headquartered in South Glens Falls, New York. The Institute plant processed spent catalyst materials used in the manufacture of ethylene oxide and produced silver-based products for the medical, electronic, and automotive industries.

The facility was in the process of shutting down operations when the incident occurred around 9:30 a.m. Workers were cleaning and decommissioning a tank when nitric acid and a chemical referred to as M2000A came into contact. The reaction was immediate and severe. Kanawha County Emergency Management Director C.W. Sigman described it as a violent chemical reaction that instantaneously overreacted, generating a release of hydrogen sulfide, a highly toxic gas.

First responders arriving on scene found workers dragging their coworkers out of the facility. A one-mile shelter-in-place order was issued for the surrounding area, covering a zone from West Virginia State University to the Nitro and St. Albans bridge on both sides of the river. That order remained in effect for more than five hours before being lifted.

Decontamination stations were set up along Route 25, where exposed individuals were required to remove clothing and be sprayed down before receiving medical transport. WVU Medicine Thomas Memorial Hospital in South Charleston received a significant number of patients, including individuals who had been in the surrounding area but were not inside the plant. Officials noted that symptoms among those treated included shortness of breath, coughing, and chest tightness. Physicians cautioned that additional symptoms may emerge over time.

INJURIES AND HEALTH RISKS FROM HYDROGEN SULFIDE EXPOSURE

Hydrogen sulfide is a colorless, highly toxic gas with a distinctive odor that can cause severe and life-threatening health effects even at relatively low concentrations. At high exposure levels, the effects can be instantaneous and fatal. Workers and community members exposed to hydrogen sulfide may experience:

• Severe respiratory distress, including inflammation of the lungs and reduced oxygen absorption
• Eye and throat irritation
• Neurological symptoms including dizziness, confusion, and loss of consciousness
• Long-term pulmonary damage even after initial symptoms appear to resolve
• Cardiovascular complications in cases of significant exposure

Medical professionals treating patients from the Catalyst Refiners incident noted that Bonderite, identified as one of the substances involved, is a pulmonary irritant capable of inflaming the lungs and preventing adequate oxygen from reaching the bloodstream. Physicians have acknowledged that the full scope of long-term health effects on those exposed may not be known for some time. Anyone who was in the area during the incident and has not yet sought medical evaluation should do so as soon as possible.

LEGAL OPTIONS FOR INJURED WORKERS AND COMMUNITY MEMBERS

Investigations into this incident are still in the early stages, and the full picture of what went wrong at the Catalyst Refiners plant will emerge over time. However, based on what is already known, several legal theories may be available to injured plaintiffs.

Workers injured in industrial accidents may have claims beyond standard workers’ compensation, particularly where the employer’s conduct was grossly negligent or where a third party contributed to unsafe conditions.

The fact that the plant was in the process of decommissioning at the time of the incident raises specific questions about whether proper safety protocols were followed during that phase of operations, whether workers were adequately trained and equipped for the chemical handling procedures being carried out, and whether management was aware of the risks associated with mixing the chemicals involved.

Community members who were not employees of the plant but who suffered harm from the gas release may have separate claims rooted in premises liability, negligence, or toxic tort law. West Virginia law recognizes that companies operating hazardous facilities have a duty of care not only to their workers but also to neighboring residents and emergency responders who may be placed in harm’s way by their operations.

For families of the two workers who lost their lives, wrongful death claims may provide a legal path to compensation for the financial and emotional losses their families will bear.

Emergency responders who were injured while responding to the scene also deserve careful legal evaluation of their rights. While certain legal protections can limit claims by first responders in some circumstances, each case turns on its specific facts, and our attorneys are prepared to evaluate those claims individually.
