Carbon monoxide (CO) is a poisonous gas that can cause sudden illness and death. Symptoms may resemble the flu- headache, tiredness, dizziness, upset stomach, nausea, vomiting, chest pain, and confusion. Breathing in a lot of CO gas can make you pass out or kill you.


There are no warning properties (no odor or taste) to let you know that you have been exposed to this deadly gas.  The only way to know is by installing a carbon monoxide alarm.  The alarm will sound when air concentrations inside of a building become dangerous, but sometimes symptoms can be felt even before the alarm sounds.  If several members of a household experience these symptoms when they are home, but feel better when they are away from the home, this may indicate a CO problem. Don’t wait for the alarm to sound.  Get people and pets out of the building immediately.  Call 911 once you are outside.

Carbon monoxide gas forms when fuels like gasoline, propane, natural gas, kerosene, wood, charcoal, and diesel fuel do not burn up completely.  Common sources include portable generators, propane, gasoline, or kerosene heaters, gas or oil furnaces, charcoal grills used indoors, gas appliances and motor vehicle exhaust.
