NITROGEN DIOXIDE HAZARDS

Nitrogen dioxide (NO₂) is a by-product of fuel burning.  Fireplaces, furnaces, wood stoves, kerosene or gas space heaters, and gas-fueled appliances can all potentially release NO₂ into the home.  Low levels of this gas can cause eye, nose, and throat irritation.  People with asthma may experience increased bronchial symptoms and/or shortness of breath.  Long-term exposure to NO₂ at high levels can lead to chronic bronchitis.  Since gas appliances, fireplaces, and wood-burning stoves are used in many homes, it is important for people to have appliances and chimneys inspected regularly to ensure that they are not emitting noxious fumes into the house.  Any NO₂ source that is identified should be repaired, replaced, or properly vented to eliminate health hazards.

P.S.  Elderly people, young children, and people with respiratory diseases may be very sensitive to NO₂.  Consult an allergist if asthma symptoms worsen or interfere with daily activities.
