The emergency room at St. Michael’s Hospital has partially reopened, nearly two days after flooding halted services at the department.

A pipe burst at 1 a.m. on Tuesday morning causing flooding in the busy downtown ER.

The hospital now has to deal with electrical issues, dry wall and plaster damage and structural damage in the ceiling.

Equipment such as breathing machines and X-ray scanners were also damaged by the flooding.

“We had quite a significant damage from the flood,” said Dr. Glen Bandiera, chief of emergency medicine at the hospital. “What this means is we have to cordon off large portions of the department so that they can be adequately cleaned and inspected for damage.”

Officials haven’t released the cost of the damage.

Doctors are accepting ambulances transporting trauma or critically ill patients. The ER is not accepting walk-in patients.

It is unclear when the emergency room will fully reopen.
