Reece explained that small leaks can occur anywhere a joint is made between the piping and machine. He said people in the industry call those “nuisance leaks” because they happen on a normal basis with refrigeration and don’t pose a danger to workers.
Speaking Jan. 28 at a press briefing about the incident at Foundation Food Group, Nicholas Ancrum, vice president of human resources for Foundation, said “preliminary indications are that a nitrogen line was ruptured inside the facility.”
The Georgia Fire Marshal’s Office, Occupational Safety and Health Administration and U.S. Chemical Safety and Hazard Investigation Board have been involved with the incident and investigations are ongoing. The Hall County Sheriff’s Office is handling the death investigations.
Nitrogen is a naturally occurring element, but if it’s concentrated enough, Reece said people won’t be able to breathe in oxygen. He said the same can be said for inhaling 100% carbon dioxide or ammonia for a long period of time.
“If you don’t get enough oxygen, no matter what you’re breathing in, that’s what happens,” he said. “That’s with all refrigerants, man-made or natural.”
