On January 24, 1993, an incendiary fire occurred at a hospital in Weymouth, Massachusetts. One sprinkler operated in the room of fire origin, extinguishing the flames before firefighters arrived. The damage from flame and heat was limited to the room of origin, however, water and smoke spread into the corridor and resulted in some damage. Six staff were treated and released for smoke-related injuries. Compliance with fire safety code requirements, training of staff, and the use of automatic sprinklers significantly reduced the potential for loss of life and large property loss during this incident.
