Today, carbon monoxide poisoning is a serious problem in homes. Between 2010 and 2015, more than 2,200 people died from carbon monoxide poisoning,According to the CDC(Centres for Disaster Prevention and Control). Many illnesses due to carbon monoxide poisoning go unreported, or are attributed to influenza or other causes, and go undetected by healthcare workers who often do not test for poisoning to carbon monoxide. For many people, the moment firefighters were called in to investigate a possible carbon monoxide leak, a family could have been in dire straits. HVAC professionals are essential to protect against this deadly gas in the home.
What is carbon monoxide?
Carbon monoxide (CO) is the result of imperfect fuel combustion. It is a colorless and odorless gas, slightly lighter than air. When combustion occurs, the normal result is carbon dioxide (CO2) and water. However, carbon monoxide is produced when only one oxygen atom, instead of two, combines with carbon. Normally the CO will be vented to the outside and should not cause any problems. However, when there is a problem with the venting of this toxic gas, carbon monoxide can begin to build up in the home, causing health issues.
Carbon monoxide is dangerous when inhaled because it binds to red blood cells in the same way that normal oxygen replaces the oxygen the body needs. Over time, carbon monoxide can build up in the body and cause serious problems. This accumulation is particularly problematic for people who do not leave the house often, such as the sick and the elderly. Doctors often misdiagnose carbon monoxide poisoning because the symptoms often resemble those of the flu. Some people may find it easier to get out of the house and get some fresh air during their doctor’s visit, which relieves symptoms.
Problems with home carbon monoxide alarms
Many homes now have carbon monoxide detectors/alarms, just like they have smoke detectors. Many of these alarms are set to operate when they detect 40 to 70 ppm (parts per million) of CO in the air. This level is too high. By then, the family was already at serious risk of CO poisoning.
Most household CO detectors are designed to operate at altitudes where people would normally breathe. CO is lighter than air, so if these detectors are installed too low, they may not accurately gauge the amount of CO that occupants are breathing. More expensive models work when placed closer to the ground, but even these are often set to sound an alarm at 40 ppm.
While having a CO detector in your home is better than nothing, by the time you’re alerted to a problem, chances are your family has already suffered the disastrous consequences of CO inhalation.
Appropriate CO level
Any amount of CO in the house is abnormal and the cause should be investigated. Even low levels of CO can cause illness because carbon monoxide builds up in the body over time. However, having a certain level of CO is definitely a danger and immediate action should be taken to prevent illness or even death.
Here are some significant levels of CO and their effects:
3 to 7ppm
Results in one
14% increase in hospitalizations
Can significantly increase the number of deaths from heart disease.
Causes a significant increase in cardiovascular disorders.
30 to 35ppm
Alerts may be available on some CO detectors. May cause exertional angina.
First warning by multiple CO detectors when maintained for 30 days. Apartment dwellers may experience headaches, dizziness, weakness, irregular heartbeat, etc.
As mentioned earlier, health problems can occur at significantly lower levels of CO in the air when home occupants stay indoors for long periods of time. Because the elderly and infirm are already more susceptible to the effects of CO poisoning, they often feel the negative effects of CO more quickly.
Professional inspection by an HVAC technician
HVAC professionals have three main options for equipment used to detect CO in homes. These are ambient air testers, pump analyzers and combustion analyzers.
Ambient air monitors are the most popular professional CO detectors, in part because they are relatively inexpensive, with some costing less than $200. These devices have an ambient air sensor and a digital CO level reader. Ambient air testers are easy to use and require no special training.
Ambient air testers cannot test raw exhaust or hot air under any circumstances. It is also important that the user properly calibrates the device and uses it according to its specifications. The outdoor ambient air tester should first be used to set the reading to zero. Only then can the device be used internally to measure the possible presence of CO in the house.
Pump analyzers can provide additional information to find the cause of CO leaks in your home. The pump driven analyzer can test combustion gas products and hot air as well as ambient air. This can be invaluable not only for detecting a CO problem, but also for locating the device or equipment causing the CO leak.
This add-on comes at a price, as the cost of most pump analyzers is more than twice that of an ambient air tester. Some devices have the ability to graph CO measurements over time and can send readings to a printer to provide a permanent record. These devices should also be calibrated outside the home before being tested indoors.
The most powerful CO tester is the combustion analyzer. These instruments can perform all the functions of a pump analyzer or ambient air tester and can also measure oxygen and carbon dioxide in air. In this way, they can assess the efficiency of combustion by creating a picture of the proportions of gases in the smoke products. This feature can help determine the cause of a CO leak.
Combustion analyzers are the most expensive CO detectors in an expert’s arsenal and can cost between $600 and $2,000, depending on the features. Special training may be required to understand the information provided by the combustion analyzer, including the proper burn rate. Like other devices, this one needs to be calibrated regularly and not outside the home before being tested indoors.
HVAC professionals are often the first line of defense in detecting and responding to a home carbon monoxide situation. It is therefore their responsibility to watch for signs of carbon monoxide and take steps to protect residents. By using proper equipment and being aware of potentially dangerous levels, HVAC technicians can save lives and improve the health of those whose homes they serve.
Popular questions about how to test carbon monoxide
how to test carbon monoxide?
To test a carbon monoxide detector, hold down the “test” button until you hear two beeps sound off. Once you hear these beeps, release your finger off the test button.
How do you test for carbon monoxide in your home?
The easiest way to see if there is carbon monoxide inside your home is with a carbon monoxide detector (which also includes an alarm). In fact, many building codes require a carbon monoxide gas detector.
Can you detect carbon monoxide without a detector?
CO is almost undetectable unless you have a decent detector in place. But it is possible to spy some tell-tale signs that dangerous levels of carbon monoxide may be in the atmosphere. Alarm bells should ring if you spy soot or yellowy-brown stains on or around fuel appliances.
How do you know if you carbon monoxide?
What are the symptoms of CO poisoning? The most common symptoms of CO poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. CO symptoms are often described as “flu-like.” If you breathe in a lot of CO it can make you pass out or kill you.
How do you know if you have a carbon monoxide leak?
