Frigid weather prompts CO warning

Carbon monoxide poisoning risk from heating sources

As temperatures drop in Connecticut, the risk of carbon monoxide poisoning tends to rise, according to the Connecticut Department of Public Health.

Carbon monoxide gas is an odorless, colorless gas. It has no other warning properties. The only way to detect the gas is with a carbon monoxide alarm.

Every resident using oil, liquid propane, natural gas or wood and pellet stoves should take some time to ensure their heating system has been cleaned and inspected in the last year. Carbon monoxide gas can form and build up in a home if the burning of fuel is incomplete.

“If you think you may have carbon monoxide poisoning, get people and pets out of the house immediately,” the department said.

Carbon monoxide alarms should be tested on a consistent basis to be sure it’s properly working. The Department of Public Health said residents who don’t have an alarm should take some time now to purchase one.

The alarms should be close to a bedroom or wherever residents spend most of their time. As a precaution, an alarm could be placed near a furnace to set off an early warning signal.

“It is very important to have a working carbon monoxide alarm in your living space because the deadly gas can enter your home by getting in around window casings, door frames and any penetrations through outside walls,” the department said.

Symptoms of carbon monoxide exposure tend to mimic those of the flu — headaches, feeling lightheaded and fatigue.

Long-term exposure to carbon monoxide without treatment can be dangerous, leading to brain damage or even death. When it enters the body, carbon monoxide targets the bloodstream, replacing oxygen.

All public and private schools buildings in Connecticut are required to have carbon monoxide alarms. Certain one- and two-family homes are required to have alarms if they have building permits issued on or after Oct. 1, 2005.

If residents are buying or selling one- or two-family homes where building permits were issued after Oct. 1, 2005, the seller must provide an affidavit that certifies that the home is equipped with working carbon monoxide detection or that there is no possible exposure source.

Questions about required placement of carbon monoxide detection and warning equipment should be directed to local building officials or local fire marshals.
