NYC Hazards: Carbon Monoxide

Carbon Monoxide

Carbon monoxide — a colorless and odorless gas — is a normal by-product of fuel combustion that can be created by typical heating fuels (i.e., oil, coal, wood, gasoline, kerosene, diesel fuel or natural gas). High levels of carbon monoxide indoors, however, can be dangerous to your health, and can cause serious illness or death if inhaled in large concentrations.

Carbon monoxide can build up to a dangerous level if a fuel-burning appliance isn't operating properly, or is not safely venting fuel combustion by-products. For instance, dangerous levels of carbon monoxide can be produced from improperly vented furnaces, plugged or cracked chimneys, water heaters, space heaters, fireplaces, stoves, and tail pipes.

Running a vehicle inside a garage is the most common carbon monoxide danger. During the heating season, when fresh air circulation is reduced, it's especially important to prevent carbon monoxide buildup indoors.

Hundreds of people die from carbon monoxide poisoning every year, and thousands of others suffer dizziness, severe headache, and nausea. The most common symptom of carbon monoxide poisoning is headache. However, symptoms may also include dizziness, chest pain, nausea, and vomiting. In severe cases, people can become increasingly irritable, agitated and confused, eventually becoming lethargic and lapsing into unconsciousness. Everyone is at risk, however, people with low red blood cell counts, heart or respiratory ailments as well as infants are at higher risk.

If you suspect carbon monoxide poisoning:

  • Leave your home
  • Call 911
  • Get any victims to fresh air immediately
  • Open windows
  • Call your gas provider


Tips for Preventing Carbon Monoxide Poisoning
  • Install a carbon monoxide detector in your home and check it regularly to make sure the battery is working. NYC law requires owners to provide and install at least one approved carbon monoxide alarm within 15 feet of the primary entrance to each sleeping room.

  • Make sure your heating system is kept clean and properly vented; have worn or defective parts replaced.
  • Have your fireplace, chimney, and flue cleaned every year to remove soot deposits, leaves, etc.
  • Kerosene heaters are dangerous and illegal in New York City.
  • Don't heat your home with a gas stove or oven.
  • Do not use any gas-powered appliance, such as a generator, indoors.
  • Never use a charcoal grill or a hibachi indoors.
  • Automobile exhaust contains carbon monoxide. Open your garage door before starting your car and do not leave the motor running in an enclosed area. Clear exhaust pipes before starting a car or truck after it snows.
