In this study, a combustion experiment of the monitor, body, desk, chair and electric blanket used in daily life was carried out using the oxygen consumption rate principle-based Room Corner Tester(RCT), in order to provide practical data about heat release rates and smoke release rates of daily supplies. As the result, the computer monitor's maximum heat release rate was $166.28kW/m^2$. This is the relatively highest heat release rate among the five daily supplies and 20.55 times bigger than the body. This was followed by the chair, electric blanket, desk and computer body. The computer monitor showed the highest total heat release rate at $52.5kW/m^2$ and the total smoke release of the desk, electric blanket, computer body, monitor and chair was $35,274m^2/m^2$, $31,859m^2/m^2$, $27,121m^2/m^2$, $14,369m^2/m^2$, and $8,403m^2/m^2$ respectively. Therefore, it is considered that heat transfer in the monitor and electric blanket with high heat release rates is fast due to the high heat quantity in the event of fire and the desk can be an important clue to measure the direction and intensity of flames, because this leaves many traces of soot caused by much smoke.
