Two people were killed in an explosion on the grounds of a Veterans Affairs (VA) Hospital in West Haven on Friday morning.

Officials on scene told News 8 crews that one of the deceased was a hospital employee and the other was an outside contractor.

A spokesperson for the VA told News 8 the incident was due to a leak in the steam plant, which is not part of the hospital building. The pair was fixing the leak when the explosion occurred.

It is unclear exactly what happened.

West Haven police and Connecticut State Police responded to the scene at the request of the city’s fire marshal.

State police told the Associated Press they are sending three detectives from their fire and explosion investigation unit.

Smoke could be seen coming from the building when News 8 arrived.

A news conference is scheduled for 2 p.m. You can watch it live on the News 8 app.

News 8 has a crew on the way and will update this story as more information comes in.

The boiler probably dry fired. Mandy someone opened the water feed.

WTNH updated their article to say two were killed, three were injured. One of the persons who died was a VA employee who was a U.S. Navy veteran.

A little more information on the incident and the second victim.

Connecticut State Police have now identified both victims who were killed in what investigators described as a ‘pressure event’ that led to super-heated water vapor to fill the room they were working in at the VA Connecticut Healthcare System West Haven Campus on Friday.

Police say that on Friday, Nov. 13, the Connecticut State Police Fire & Explosion Investigation Unit responded to the report of a steam boiler explosion at 950 Campbell Avenue, which is the campus of the West Haven VA hospital.

It was later determined that two people died in the blast. One was previously identified as 60-year-old Euel Sims, an employee of the VA Facility Maintenance Service.

On Thursday, police released the identity of the second man killed. He was identified as 36-year-old Joseph O’Donnell, an employee of a contractor working on the steam system.

Three others suffered minor injuries in the incident.

Officials with the Department of Veteran Affairs Police Service, DEEP, FBI, ATF, State Building Inspector, OSHA, West Haven Fire Department, West Haven Fire Marshal’s Office, West Haven Police Detective Bureau, Office of Inspector General, and the OCME, all responded to the scene.

According to state police, the CSP-FEIU investigation determined that a “pressure event” occurred within the steam system that was being worked on. “This caused super-heated water vapor to rapidly fill the room and building.” They said that this was not a fire or an explosion.

Sims and O’Donnell were not able to evacuate the room and suffered fatal injuries. There was no apparent criminal aspect.

The incident remains under investigation.
