The New Fairfield Fire Marshal's Office has a safety reminder for homeowners, following a morning fire yesterday at a home on Hudson Drive, about the importance of keeping bedroom doors closed while sleeping.  While the front of the bedroom door was severely damaged, because it was closed, the hollow core door protected the room and its contents. If this were an occupied bedroom, fire officials say the closed door could have saved a life. The cause and origin of the fire are under investigation and believed to be accidental in nature.  The homeowners and family dog were able to make it out of the house, though one person was transported to the hospital for evaluation.
