Could a refrigerator give off dangerous vapors or gases?
A refrigerator is basically nothing more than an electric motor and fan connected to a sealed cooling system (that used to contain Freon or other CFCs but now contains their more environmentally friendly alternatives). It’s possible that the gas could leak from the system. But if this were happening, the refrigerator would no longer be able to keep anything cold and you’d know about that. And the gas is inert and essentially non toxic. It’s also possible for mold to grow in a refrigerator. Not all mold is intolerant to cold temperatures. And this mold can release spores that are harmful to breath in. Mold problems are far more common than anything else. So you need to check your food and throw out anything on a regular basis that is well beyond its expiration point. And you need to keep the temperature of the refrigerator at a moderately low level… It’s also possible for the electrical wiring to have a short that slowly vaporizes wiring insulation, but you’d smell that right away as
