Patients on the mental health ward at the Queen Elizabeth II hospital in Halifax have been relocated after a flood soaked the unit on Wednesday.
Staff said an agitated patient was sent to the "quiet room" in the Abbie J. Lane Building. He then managed to smash two sprinkler heads.
Peter Graham, a spokesman for the Capital District Health Authority, said water flooded the unit, forcing an evacuation.
"There was lots of water, obviously, on the floors and so cleanup was done almost immediately. Patients were moved out of the unit to allow the cleanup to take place."
Staff cleared an orthopedic unit at the Halifax Infirmary and 20 adult patients moved in.
The Abbie J. Lane Building is a short-term mental health ward with secure access.
Temporary ward is secure
Capital Health said it's taken steps to ensure patients are monitored and must let staff know if they're leaving their temporary accommodation.
"What we've done is restricted access on and off the unit. We have additional security in place to help monitor the movements of patients coming and going and the unit is closed as well," said Graham.
Capital Health does not yet have a cost estimate for the repairs, or for the patients' damaged possessions.
Graham said the patients are making do. "It certainly has been disruptive for them and we appreciate their patience as well as we move through this. This is certainly not an ideal situation."
He said the damage was mostly contained to the floor. The walls appeared to be undamaged.
The health authority is running dryers for another 24 hours and said it hopes the patients will be able to move back in on Friday evening.
It's the second flood at Capital Health in recent months. In November, the Bethune Building was badly damaged by a burst pipe.
