Possibility of Fire Spreading Owing to Radiant Heat from Fire Shutters in Logistics Facilities

The mock-up experiments were conducted to confirm the possibility of fire spreading, such as ignition of commodities (e.g., cardboard boxes), owing to the radiant heat, in the event of a fire in the fire shutter, which is the main fire compartment element that forms the fire compartment of logistics facilities. From the experiment, it was found that commodities located at a distance of 1, 2, and 3 m from the fire shutter can be ignited by the radiant heat of the fire shutter in the event of a fire, which can affect the spread of the fire. Therefore, to prevent the spread of the fire to neighboring fire compartments in the event of a fire in logistics facilities, it is necessary to restrict the placement of commodities within a certain separation distance from the fire shutter or install a fire shutter with radiant heat limiting performance. It is important to improve standards related to fire shutters in logistics facilities.
