The following is a list of common symptoms. This list is not meant to serve as a diagnosis.
Don't wait until illness symptoms occur or until something breaks! Have your appliances checked at least annually. If you are sick, go to a doctor and get tested for CO poisoning.
Carbon Monoxide is produced from anything that burns hydrocarbon fuel.
Whether it is gasoline, natural gas, propane or wood, they all produce carbon monoxide. The number one cause of accidental CO (Carbon Monoxide) poisoning in North America is auto exhaust in garages and the exhaust fumes from internal combustion engines.
Remember: CO is Odorless
People have died while keeping their motor vehicles running while talking or sleeping. Factors that contribute to this type of poisoning are as simple as prevailing winds bringing exhaust into the vehicle or deep snow, mud, ditches and walls restricting the exhaust ability to get safely away from the vehicle.
A carbon monoxide alarm/detector should be used whenever a hydrocarbon based combustion system is used. The choice of alarms, detectors and monitors may be a matter of life or death.
There are approximately 50,000 emergency room visits for CO poisoning in the USA annually.
Every home should have at least one carbon monoxide detector that is more sensitive to the health needs of vulnerable populations. It is very important to know that alarms listed by the UL 2034 standard may not be the best for some people of vulnerable health. UL 2034 alarms are not required to sound off until 70 PPM (Parts Per Million molecules of air) of CO are present for as long as 4 hours. That standard does not even meet up to OSHA workplace standards for alarming. The test button on UL 2034 alarms does not tell you if the sensor is working; it just tells you that the audible alarm is working. You have no way of knowing if the sensor has failed.
UL requires listed alarms to notify consumers by product package instructions that suggest people of vulnerable health, use a better alarm than that listed under UL 2034. COSA (Carbon Monoxide Safety Association) describes these people to include; pregnant women, infants and people with heart or respiratory complications and chronic depression.
UL 2034 alarms have only been tested at levels of 70 PPM, 150 PPM and 400 PPM.
The most common maximum concentration of CO for civilian evacuation and the wearing of self-contained breathing apparatus by fire departments around North America is 35 PPM of CO.
At the very least, a carbon monoxide alarm should display CO levels to the user in PPM.
The health effects of CO poisoning can vary significantly due to age, sex, weight, and overall state of health. CO is measured in Parts Per Million or PPM; out of a million molecules of air, how many are carbon Monoxide?
The times given below, respective to the levels referenced in this chart, are for healthy people unless otherwise stated.
