Officials said the CSP-FEIU investigation also determined that there was no fire or explosion, but rather a “pressure event” within the steam system that was being worked on.
This event caused super-heated water vapor to rapidly fill the room and building, officials continued.
According to a release, Sims and O’Donnell were not able to evacuate the room and hence suffered fatal injuries.
It was also noted that there was no apparent criminal aspect.
VA officials confirmed that Sims was an employee and U.S. Navy veteran, while O'Donnell was a contractor.
Three other people reported minor injuries related to this incident.
The U.S. Department of Labor, Occupational Safety and Health Administration (OSHA) will be continuing the investigation, assisted by CSP-FEIU, the State Building Inspector’s Office, and West Haven Police Detectives.
