Special to the RecordShown are Chelsea’s Engine 4 Lieutenant David Asci and Firefighers Kevin Gomes and Santos Hernandez, who assisted with the delivery of a healthy baby girl. After expectant parents attempting to reach a Boston hospital became stuck in heavy gridlock traffic in Charlestown’s CANA Tunnels on the morning of Tuesday, July 21, Chelsea’s Engine 4 firefighters assisted with delivery of a healthy baby girl. Firefighters immediately assessed the newborn, cleared her airway to ensure she was breathing effectively, then clamped and cut the umbilical cord. “Our firefighters train extensively for medical emergencies, but helping to bring a child into the world is a truly special experience. The Chelsea Fire Department extends our congratulations to the proud parents on the birth of their daughter.”
