CSB Investigates Fatal Chemical Release at West Virginia Refining Facility
According to Chemical Engineering, the U.S. Chemical Safety and Hazard Investigation Board (CSB) has launched an investigation into a fatal chemical release that occurred April 22 at the Catalyst Refiners, Inc. facility in Nitro, West Virginia. The incident killed two workers and sent more than 30 others for medical care, with one reportedly in critical condition. Initial information indicates nitric acid mixed with another substance during equipment cleaning and decommissioning, generating toxic hydrogen sulfide gas inside a building with numerous employees present. A shelter-in-place was also issued for the surrounding community.
What It Means for Subcontractors
- Equipment cleaning and decommissioning work is exactly the kind of task contracted out to third-party crews, meaning subcontractors performing similar scope at chemical or refining facilities need rigorous hazard reviews before any work begins.
- CSB investigations frequently result in recommendations that affect facility operating procedures and contractor safety requirements, so companies doing maintenance or turnaround work at process facilities should monitor findings closely.
- Mixing incompatible chemicals during cleaning operations is a recognized process safety risk. Subcontractors should confirm with facility owners that all hazardous residues have been identified and controlled before starting any decommissioning scope.
