Where should oil burning appliances not be installed?

Oil burning appliances should not be installed in areas where there are combustible dusts or flammable liquids, gases, or vapors because this creates a significant fire hazard. The presence of flammable materials can easily ignite from the heat generated by the oil burning appliance, leading to dangerous situations including explosions and uncontrollable fires. Ensuring that such appliances are installed in safe environments that are free from these hazards is critical for maintaining safety standards and preventing potential disasters.

While other locations such as residential garages, near swimming pools, and in attics and basements may have their own limitations or considerations, the key concern in option B is the direct and immediate risk that flammable substances pose, which elevates the need for stringent safety measures and proper installation guidelines.
