Slow Cooker Fire Statistics

GITNUXREPORT 2026

Slow Cooker Fire Statistics

Cooking is tied to about 1 in 6 home fire injuries and $1.4 billion in property loss each year, yet slow cookers typically draw only a small slice of household electricity use and still hinge on the same unattended and abnormal operation risks that regulators and lab tests target. This page connects CPSC incident and recall data with IEC 60335-2-14 overheating and endurance results, so you can see exactly why a device that runs 300 W for 10 hours can be safer when used correctly and riskier when it is not.

Slow cooker fires are often treated as a low drama risk, yet U.S. cooking is behind about 1 in 6 home fire injuries, roughly 16%. At the same time, safety test standards like IEC 60335-2-14 focus on lid locking, temperature rise, and abnormal operation, because a small change in heating control can mean the difference between steady cooking and runaway overheating. Let’s look at how CPSC incident and recall records, energy cost math, and lab findings line up so you can see where the risk concentrates and why “unattended” is a recurring theme.
