The onset of cold weather increases the risk for exposure to poisonous carbon monoxide gas as more people use space heaters and portable generators, warns the American Association of Poison Control Centers. Every year, hundreds of deaths and many thousands of illnesses result from exposure to carbon monoxide.

"All fuel powered engines produce carbon monoxide gas,” said AAPCC board member Edward P. Krenzelok, PharmD, director of the Pittsburgh Poison Center. "Although such devices are safe if used correctly, a malfunction or improper ventilation can make these common household appliances deadly.”

Carbon monoxide gas is lethal, even though it is colorless, odorless and tasteless. It may kill quickly or slowly, and the warning signs specific to carbon monoxide are also common to the flu and food poisoning. Even when it is not fatal, carbon monoxide can cause permanent damage to the brain and other parts of the nervous system. Symptoms include aches, dizziness, headache, confusion and other symptoms also found with flu and typical cold-weather viruses.

Tips to avoid poisoning→Have all of your combustion appliances and especially your furnace inspected and adjusted before every heating season.

→Have your chimney, fireplace, wood stoves and flues inspected before every heating season.

→Have chimneys and flues repaired as needed.

→Do not use charcoal grills indoors for cooking or heating.

→Do not use your oven for heating your home.

→Do not leave your car’s engine running in an enclosed or attached garage, even if the door is open.

→Install a carbon monoxide alarm outside sleeping areas in your home.
