CSB Releases Investigation Update into July 2024 Hazardous Ammonia Release at Cuisine Solutions Facility in Virginia

The U.S. Chemical Safety and Hazard Investigation Board (CSB) released an update on the agency’s investigation into the July 31, 2024, hazardous ammonia release at the Cuisine Solutions, Inc. food processing facility in Sterling, Virginia. The incident involved the accidental release of anhydrous ammonia, a hazardous chemical commonly used in refrigeration systems.  Dozens of employees were injured by the release, some seriously.

The update highlights the key facts surrounding the event. The incident occurred due to the discharge of an emergency pressure relief valve, which resulted in the release of approximately 170 pounds of anhydrous ammonia, according to company officials. As the toxic cloud spread through the facility, personnel were evacuated through several exits,  some of which were in close proximity to the ammonia release. During the evacuation a number of workers were exposed to the hazardous ammonia which led to exposure symptoms such as difficulty breathing.

CSB Chairperson Steve Owens said, “Anhydrous ammonia is a toxic substance, and exposure to even small amounts can have significant adverse health impacts. The formation of a toxic ammonia cloud like the one in this incident can pose serious potential risks not just to those in the immediate vicinity, but to the surrounding community as well.”

The CSB’s update also highlights the health risks associated with   anhydrous ammonia, given its toxicity. The incident underscores the importance of having effective emergency response and evacuation procedures in place for workers, as well as the need for regular equipment maintenance.
