A significant number of house fires are believed to be caused by electrical appliances. Many firefighters suspect that some of these fires are caused by electric rice cookers but lack empirical evidence to counter the denials of major electric rice cooker companies. To investigate this hypothesis, a previous fire suspected to be caused by an electric rice cooker was identified for an experiment in which an electric rice cooker was intentionally short-circuited in similar conditions to determine if the rice cooker was a possible cause of ignition. By analyzing the combustion traces of the past fire and the points of ignition in the short-circuiting experiment, this study concludes that the cause of ignition in the past fire is likely the electric rice cooker. By identifying the electric rice cooker as the cause of ignition, we hope that the reliability of future fire investigation results is improved and further research can be used as reference for analysis of future home appliance fires.
