Can Your Slow Cooker Start a Fire?

Slow cookers and crockpots are an easy and convenient way to cook food. However, although commonly used, this cookware can be a fire hazard. When you leave your slow cooker on too long, temperatures can rise to dangerous levels. Not only can the handles melt, but a fire can start. While crockpots are a great tool to have in the kitchen, it’s important to not take them for granted.

How a Slow Cooker Fire Starts

The most common way a slow cooker fire starts is when the grease drips onto the heating element of the pot and catches on fire. Other ways a fire may start are from over filling the pot, using too high heat, and leaving the crockpot unattended.

How Bad Can a Slow Cooker Fire Be?

Cooking is the number-one cause of U.S. home fires. According to a study by the National Fire Protection Association (NFPA), between the years of 2011 and 2015, “an annual average of 70 cooking fires involving slow cookers resulted in two civilian injuries, no deaths, and $3.3 million in direct property damage”. From these statistics, the chances of a fire starting from your slow cooker or crockpot are slim, but possible.

Once a slow cooker fire occurs in your kitchen though, the damage can be equivalent to an oven fire. The heat and flames from the unit and outlet can spread to the walls, cabinets—affecting the entire kitchen. Since these kitchen tools are plug-in’s, your overall electrical system may be affected as well.

Even after the fire is out, damage can continue to impact the rest of the house. Soot, smoke stains, and mold can spread throughout the rest of your home. At this level of severity, contacting fire cleanup and restoration services would be needed.
