Hackensack University Medical Center crews are working to report damage left by an electrical fire.

It happened at 6:38 a.m. Wednesday.

Firefighters investigated initial reports from hospital security of smoke coming from the supply room but found that an electrical busbar shorted out and activated a sprinkler, according to officials.

The electrical equipment shut down, and the sprinkler put of remaining hot spots. The damage was contained to the room, equipment and some hospital supplies.

No injuries were reported, and no evacuations took place.
