Mattapoisett Fire Rescue

“Shortly after 9am this morning, Chief 1 and Engine 3 responded to a residence on Ned’s Point Road for a reported smell of gas.
The crew of Engine 3 entered the home and found an exhaust smell that was registering on our carbon monoxide meter at 200ppm, an extremely high level. Firefighters exited the building and donned our SCBA’s and then continued investigating. In one area of the home our meter registered 500ppm and then maxed out reading HIGH.
It was determined that a indoor pool heater had recently been turned on but during renovations to the home the heater vent pipe had been removed and shingled over resulting in exhaust and CO being forced back into the home. Our crews ventilated and secured the gas to the appliance.
CO is extremely dangerous in levels this high. Knowing that the levels were over 500ppm this incident could have resulted in unconsciousness and death. Luckily no one is living in the home as its undergoing renovations.”
