What type of heater is commonly associated with carbon monoxide poisoning in winter?

Space heaters are commonly associated with carbon monoxide poisoning during winter because many of these devices can burn fuel, such as propane or natural gas, to generate heat. When used in enclosed spaces without adequate ventilation, it can lead to a dangerous accumulation of carbon monoxide, which is a colorless and odorless gas. Unlike electric heaters, which do not produce carbon monoxide, space heaters that rely on combustion processes can pose a significant risk if safety measures are not observed. This makes it crucial for users to ensure proper ventilation and to regularly maintain these appliances to minimize the risk of carbon monoxide exposure.

Central heating systems and wall heaters may also present risks if they are not properly vented, but space heaters are particularly noted for their frequent use in smaller, unventilated areas where carbon monoxide poisoning is more likely to occur.
