No, you cannot get carbon monoxide poisoning from a refrigerator or freezer. Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is produced by the incomplete combustion of fuels such as natural gas, gasoline, propane, and wood.
Refrigerators and freezers do not produce carbon monoxide as a byproduct of their normal operation. They are electrical appliances that cool and preserve food through the use of compressors, fans, and refrigerant gases.
However, it's important to note that some older models of refrigerators and freezers may use a coolant called chlorofluorocarbon (CFC), which is harmful to the environment but not to human health when used in proper amounts and not released into the air. Modern refrigerators and freezers typically use more environmentally friendly refrigerants such as hydrofluorocarbon (HFC) or hydrochlorofluorocarbon (HCFC).
If you have any concerns about the safety or operation of your refrigerator or freezer, it's always best to refer to the manufacturer's guidelines or consult with a qualified professional for proper maintenance and troubleshooting.
