An emergency medical necklace helped save the life of a woman who was trapped by flames in a Greenwich house Tuesday. Police and EMS responded to 16 Arnold Road after receiving the woman's emergency signal. They say they saw smoke and called Greenwich firefighters who were able to make their way to the second floor and bring the woman out. The woman is now at Norwalk Hospital inside a hyperbaric chamber. At this point fire inspector Chris Doyle does not know what exactly caused the fire, but said it started in the kitchen. Doyle said he is very proud of how the team responded and said all of the firefighters involved will be getting commendations for their actions.
