👉 Appliances that emit fumes, often referred to as "fume-emitting" or "toxic fumes" devices, release harmful gases or vapors into the air during their operation. These can include items like certain types of heaters, steam generators, and some industrial equipment. Common examples include propane heaters, which can release carbon monoxide if not properly ventilated, and some industrial boilers that emit sulfur dioxide and other toxic compounds. Fumes from these appliances can pose significant health risks, including respiratory issues, dizziness, and in severe cases, long-term damage to organs. Proper ventilation, regular maintenance, and adherence to safety guidelines are crucial to mitigate these risks. Users should always check for proper installation and operation, and consider using exhaust systems or fume hoods to reduce exposure.
