In our energy-conscious society, older homes have been caulked and insulated, and newer homes are almost airtight. If CO is released, it has no way to escape and no outside air is leaking in. First and foremost, Dr. Bayer recommends that homeowners have their heating system inspected, and faulty and worn parts replaced. Fireplaces and wood and coal stoves should also be cleaned and inspected, he said. Grills, hibachis, and generators produce CO and should never be used indoors and that includes basements and garages.
Tragedies often happen during a power outage.
A CO detector would alert them to their grave mistake. Everyone should know the early signs of carbon monoxide poisoning, said Dr. Bayer. Symptoms include headache, nausea, unclear thinking, shortness of breath, weakness, and loss of muscle control. Symptoms often mimic the flu leading to misdiagnosis by both patient and physician. Be suspicious of CO poisoning if symptoms vanish when you leave your home or other regularly frequented environment, said Dr. Bayer.
