Carbon monoxide (CO) Overview

Carbon monoxide (CO) is a colorless, odorless, and tasteless poison gas that can be fatal when inhaled. CO inhibits the blood’s capacity to carry oxygen.

Possible Sources of CO

1. Excessive spillage or reverse venting of fuel-burning appliances caused by: i) Outdoor ambient conditions such as wind direction and/or velocity, including high gusts of wind; heavy air in the vent pipes (cold/humid air with extended periods between cycles), ii) Negative pressure differential resulting from the use of exhaust fans, iii) Simultaneous operation of several fuel burning appliances competing for limited internal air. iv) Vent pipe connection vibrating loose from clothes dryers, furnaces, or water heaters, v) Obstructions in or unconventional vent pipe designs which amplify the above situations.
2. Extended operation of unvented fuel-burning devices (range, oven, fireplace, etc.).
3. Temperature inversions which can trap exhaust gasses near the ground.
4. Car idling in an open or closed attached garage or near a home.

Symptoms of CO Poisoning
Initial carbon monoxide poisoning symptoms are similar to the flu with no fever and can include dizziness, severe headaches, nausea, vomiting, and disorientation. Everyone is susceptible but experts agree that unborn babies, pregnant women, senior citizens, and people with heart or respiratory problems are especially vulnerable. If symptoms of carbon monoxide poisoning are experienced seek medical attention immediately. CO poisoning can be determined by a carboxyhemoglobin test.

The following symptoms are related to CARBON MONOxIDE POISONING and should be discussed with ALL members of the household:

1. MILD EXPOSURE: Slight headache, nausea, vomiting, fatigue (often described as “Flu-like” symptoms).
2. MEDIUM EXPOSURE: Severe throbbing headache, drowsiness, confusion, fast heart rate.
3. EXTREME EXPOSURE: Unconsciousness, convulsions, cardio-respiratory failure, and death. The above levels of exposure relate to healthy adults. Levels differ for those at high risk. Many cases of reported carbon monoxide poisoning indicate that while victims are aware they are not feeling well, they become so disoriented they are unable to save themselves by either exiting the building or calling for assistance. Also, young children and household pets may be the first affected.
   • WARNING! Exposure to high levels of carbon monoxide can be fatal or cause permanent damage and disabilities.
   • WARNING! The device may not prevent the chronic effects of carbon monoxide exposure and the device will not fully safeguard individuals at special risk.

Recognizing Nuisance Alarms

Smoke Nuisance

SILENCE:
If you know why the alarm is sounding, and you can verify that it is not a life-threatening situation, you can push the button to silence the alarm for 8-10 minutes. If the smoke is not too dense, that unit will be silent. After the SILENCE period, the smoke alarm will automatically reset and sound the alarm if particles of combustion are still present. You can use SILENCE repeatedly until the air has been cleared of the condition causing the alarm.

NOTE:
Dense smoke will override SILENCE and sound a continuous alarm. If no fire is present, check to see if one of the reasons listed in “Locations to avoid” may have caused the alarm. If a fire is discovered, get out and call the fire department or 911.

This alarm is designed to minimize nuisance alarms. Cigarette smoke will not normally cause the unit to alarm unless the smoke is blown directly into the alarm. Combustion particles from cooking may set off the alarm if it is located too close to a cooking appliance. Large quantities of combustible particles are generated from spills or when broiling. Using the fan on a range hood that vents to the outside (non-recirculating type) will also help prevent nuisance alarms from occurring by removing these combustible products from the kitchen.

Carbon Monoxide (CO) Nuisance

RESET:
Pushing the button during the CO alarm allows the unit to reset calculations and double-check for the presence of CO. If the unit re-alarms within 6 minutes, it is sensing high levels of CO which can quickly become a dangerous situation. Move to fresh air and call 911.

WARNING!
It is impossible to determine the source of a co-alarm using sight or smell. Always consider a co-alarm event as dangerous

Good safety habits

Good safety habits – develop and practice a plan of escape
Prepare and practice a home escape plan twice a year, including drills at night. Know of two ways out of every room (door & window) and identify a meeting place outside the home where everyone will gather once they have exited the residence. When two people have reached the meeting place, one should leave to call the fire department’s telephone number ( __ ) while the second person stays to account for additional family members. Establish a rule that once you’re out, you never re-enter under any circumstance!

• Make a floor plan indicating all doors and windows and at least two escape routes from each room. Second-story windows may need a rope or chain ladder.
• Have a family meeting and discuss your escape plan, showing everyone what to do in case of fire and where to meet after they leave the house.
• Ensure that small children hear the alarm and wake when it sounds. They must wake up in order to execute the escape plan. Practice allows all occupants to test your plan before an emergency. You may not be able to reach your children. It is important they know what to do.
• Familiarize everyone with the sound of the smoke/CO alarm and train them to leave your home when they hear it.
• Current studies have shown smoke/CO alarms may not awaken all sleeping individuals, and that it is the responsibility of individuals in the household who are capable of assisting others to provide assistance to those who may not be awakened by the alarm sound, or to those who may be incapable of safely evacuating the area unassisted.
• Install and maintain fire extinguishers on every level of the home and in the kitchen, basement, and garage. Know how to use a fire extinguisher prior to an emergency.
