A mass casualty incident was declared in Danbury yesterday as firefighters responded to the prison.  A fire was reported in a laundry bin filled with towels at the Federal Correctional Institution around 2:15pm.  The bin was brought outside the laundry room by staff before firefighters arrived.  7 employees were triaged and transported to the hospital for smoke inhalation as well as inhalation of powder from Dry Chemical extinguishers. The mass casualty incident was declared so Danbury Hospital Staff could prepare for multiple patients.  The fire is under investigation by Federal Authorities, but does not appear suspicious at this time.
