Are furnace oil fumes dangerous

Yes, furnace oil fumes can be dangerous. They may contain harmful substances, including volatile organic compounds (VOCs) and particulate matter, which can lead to respiratory issues, headaches, and other health problems with prolonged exposure. Additionally, improper combustion of furnace oil can produce carbon monoxide, a colorless and odorless gas that is highly toxic. It's important to ensure proper ventilation and regular maintenance of heating systems to mitigate these risks.
