Columbia Gas of Massachusetts Offers Simple Tips to Prevent Carbon Monoxide Poisoning

Nov 23, 2016

Westborough, MA – With colder temperatures settling into the region, and heating systems running more frequently, increases in carbon monoxide incidents occur. 

Whether you heat your home with natural gas, oil, coal or wood, your heating system can produce toxic carbon monoxide if it is not working properly or not adequately vented. 

Columbia Gas reminds customers to learn the symptoms and preventative actions to avoid carbon monoxide poisoning this winter, like installing a carbon monoxide detector.  

Carbon monoxide is a toxic gas that is odorless, colorless, and tasteless.   


Symptoms of carbon monoxide poisoning are often confused with the flu.  Such as: fatigue, headaches, dizziness, memory loss, nausea, vomiting, unclear thinking, shortness of breath, weakness, vision problems, loss of coordination, and unconsciousness.  A victim of carbon monoxide poisoning may not experience all of these symptoms - only one or a few. 

Other household symptoms include foul-smelling or stale air, the smell of exhaust fumes, a yellow/orange flame on gas ranges, furnace or water heater burners, soot around the outside of the chimney, furnace or water heater flue vent or fireplace, and large areas of condensation of water vapor on walls or windows.

What to Do 

If you suspect carbon monoxide or a natural gas leak, leave the home immediately, and from a safe location call 911 and Columbia Gas at 1-800-525-8222
