Abstract
Ducts penetrating the fire compartment are passageways for spreading the flames and smoke of igniting deposits attached to the inside or fires from outside. Fires through ducts have a fast flame propagation speed and are difficult to extinguish quickly because of the high-temperature heat. Therefore, in this study, to improve the fire risk of ducts, the need for institutional improvement is confirmed by analyzing fire cases, comparing domestic and foreign laws and standards, and analyzing the current situation. As a result, a blind spot is evident in domestic law at the location of the fire damper installation because of the mitigating condition of fire compartments. There is also a gap regarding the need to prepare preventive systems such as maintenance standards inside ducts and installation standards for fire suppression systems in commercial restaurant kitchens.
