Carbon monoxide is a silent killer. Undetectable by the human senses, it is highly toxic. Leaky chimney ducts, poor ventilation or sealed windows can contribute to carbon monoxide poisoning and lead to severe headaches, vomiting, coma and even death.
Every year, during the heating season, we receive reports of carbon monoxide poisoning, which is why police officers remind residents of the need to air rooms and inspect ventilation ducts. Special detectors can warn of the danger.
