Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.

While a hot fire can help heat up and loosen tar within your chimney, making it a recommended step before using a creosote log, it will not burn off significant existing buildup on its own. Attempting to remove built-up creosote with a hot fire is dangerous and can cause a chimney fire. For safe and effective removal of caked-on creosote, the best approach is to hire a professional chimney sweep.

Ensure you have a safe environment for them to work on, and there aren’t items such as logs, build-up of yard materials, missing or damaged shingles, and weak areas on the roof. Communicate any known electrical issues with contractors at the beginning of the project, and consider hiring an electrician to fix those. Finally, if you are attempting the project yourself, do so when there isn’t any rain, and you can safely get your footing on the roof using proper equipment, such as an extension ladder. Don’t attempt this alone, and have a helper nearby to assist.

As with any smoking appliance, a smoking oven is a concerning fire risk. It also negatively impacts your indoor air quality, which can put vulnerable people at risk of breathing problems. A dirty oven can catch fire if you don’t stay on top of regular maintenance, so remember to check your oven for signs that it’s time for a cleaning and remove buildup every three months to stay on the safe side.
