Leakage

Two friends were telling me they had some excitement on their East Marlborough cul-de-sac the other evening: fire trucks and an ambulance appeared at the house across the street. It seems that the couple had had some work done on their furnace earlier in the day, and a few hours later the carbon monoxide alarms sounded. The fire company brought in large fans to air out the house and treated the residents in the ambulance.
