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.

Wiring a light switch wrong can cause a fire if the incorrect wiring causes arcing, meaning the current jumps uncontrolled from one conductor to another. Loose wires or worn wires that are not repaired or replaced can cause arcing. If you’re not 100% sure you can do the job safely, don’t attempt to wire a light switch on your own.

Shiplap can be safe for a gas fireplace, but you should consult with a fireplace installation pro before proceeding. You need to make sure your project meets building and safety codes since shiplap is made from flammable wood. You may need to install another non-combustible material, like stone or brick, around the fireplace for a certain amount of space before you can add shiplap.

Short circuits can cause significant damage to electrical appliances, bodily harm, and potentially death to humans. For this reason, they are a serious occurrence. If you’re unable to find and fix a short circuit on your own, you must reach out to a licensed electrician for help.
