It is colorless, odorless, tasteless and potentially lethal. Carbon monoxide poisoning is called the “silent killer” because it is virtually undetectable. Carbon Monoxide Awareness Week is November 1-7 and people are being urged to take action to protect themselves and their families. Carbon monoxide poisoning can cause flu-like symptoms such as headaches, nausea, dizziness, confusion and drowsiness. At very high levels, it can cause death. As BC returns to standard time early Sunday morning and clocks fall back an hour, Vernon emergency services are reminding residents it’s also time to check smoke alarms and carbon monoxide detectors for dead batteries and expiration dates. “Remember, working smoke alarms and carbon monoxide detectors save lives!” said Fire Chief David Lind. According to the BC coroner’s office, there have been nine deaths caused by carbon monoxide poisoning in 2021 and eight so far in 2022. Carbon monoxide poisoning has caused 118 deaths in B.C. since 2012. Carbon monoxide is produced when fuels – such as propane, gasoline, natural gas, heating oil or wood – do not burn completely in fuel-burning appliances and devices. In addition to installing alarms on every floor of their home, people should test their alarms at least once a month to make sure they are in working order. Maintain and replace the batteries in each unit according to the manufacturer’s instructions. “As we approach the colder months and the furnaces are on, making sure you and your family understand that the first signs of carbon monoxide poisoning could save your life,” said Phil Gothe, chief executive officer, Technical Safety BC . “Awareness and preparedness for carbon monoxide in your home is vital. Taking the proper steps, such as installing and testing carbon monoxide alarms and having your appliances inspected by a licensed contractor annually, can help protect your home from an otherwise undetectable hazard.” During Carbon Monoxide Awareness Week, fire services, educators, government and industry work together to raise awareness of carbon monoxide poisoning’s potential dangers, symptoms, sources and prevention methods. If you suspect someone may be experiencing carbon monoxide poisoning or if the alarm sounds, get everyone out immediately and call 911 or your local emergency number.
