There are many dangers associated with gas appliances and flues, but an alarming number of UK residents do not know this. Two of the most common causes of carbon monoxide poisoning are gas appliances or flues that are not installed or ventilated properly.

Carbon monoxide (CO), a poisonous gas, is difficult to detect because it has no taste, smell, or colour. Effects of breathing in carbon monoxide include drowsiness, stomach and chest pains, and vomiting, and in some instances, CO poisoning is fatal. It is critical to act quickly if you suspect you or a family member has carbon monoxide poisoning because CO leaves the body rapidly, and test results will be inaccurate as soon as four hours after exposure to this poisonous gas.

Results of a carbon monoxide study conducted by researchers at the University of London under the direction of the HSE (Health and Safety Executive) are quite alarming. Improperly operating gas appliances were found in about 25% of the homes, and 8% of these homes were classified as having a higher than average risk for dangerous levels of carbon monoxide. Almost 50% of the residents included in the study did not know the hazards of CO. Knowing the basic safety rules for gas appliances is essential to keep your family and visitors safe from carbon monoxide poisoning and the possibility of illnesses, paralysis, and death. Considering the general lack of CO information, it is not surprising that over half of residential carbon monoxide poisonings are the result of residents taking inadequate action or not taking action at all.

A CORGI-registered technician should be your only choice for any type of service for your gas appliance, including installation, maintenance, yearly safety checks, and repairs. When you hire a CORGI-registered professional, you know that he or she will have the training necessary to perform the work safely. Choose a CORGI-registered installer to perform the required annual safety checks for your gas appliances, and look for a qualified chimney sweep to clean your flue at least every twelve months.

In order for gas to burn safely, gas appliances and flues need to be in well ventilated areas. There needs to be a constant flow of fresh circulating through the area to ensure proper appliance operation. Do not place objects on top of or next to appliances, and make sure that all vents are kept unobstructed. Most carbon monoxide poisoning incidents in homes are the result of insufficient ventilation.

Quickly turn off any gas appliance you suspect is not functioning properly. Let fresh air into the area by opening windows and doors, and turn off the gas supply line if you know how. If there is soot or stains around an appliance, a pilot light that refuses to burn, or a yellow-orange flame, your appliance is not working correctly.
