Carbon monoxide (CO) poisoning
Stoves or appliances that burn natural gas, liquid petroleum (LP gas), oil,
kerosene, coal, charcoal, or wood may produce carbon monoxide (CO), a
poisonous gas with no color, taste, or smell. CO is also produced by cars.
People often close a room tightly to keep warm or use less fuel. But heating
without ventilation can be dangerous. In a poorly ventilated space, CO can
cause serious illness, or even death.
Signs
CO poisoning seems at first like flu, but without
fever. Signs include headache, fatigue, shortness of
breath, nausea, and dizziness.
Prevention
The best way to prevent CO poisoning is to make
sure your home has good ventilation. Check
chimneys and flues for cracks, blocks, rust, and
loose connections. Never burn charcoal, gas, wood,
or other fuel inside a home, vehicle, or tent with
poor ventilation. Do not use gas appliances such
as stove tops, ovens, or clothes dryers to heat
your home. Avoid using gasoline-powered
tools and engines indoors. If you must
use them, make sure there is good
ventilation and place the engine so
exhaust fumes will go outdoors.
