A fire broke out Monday at a Coupang logistics center in Incheon, South Korea, spreading from the sixth floor to the seventh [1].
The incident raises questions about the safety of high-density storage systems in massive warehouses. While automated safety systems were active, the speed of the fire's spread suggests that interior structural layouts may override standard fire suppression efforts.
Firefighters arrived to find that fire shutters and sprinklers were already operating [1]. However, the blaze managed to move upward through the facility despite these measures. Investigators are now focusing on the specific arrangement of the warehouse's interior storage [2].
At the center of the investigation is a three-tier mezzanine shelving system located on the sixth floor [2]. The area features a floor height of 10 meters [2]. Officials suspect that the dense arrangement of combustible goods on these high shelves created a pathway for the fire to accelerate and climb to the floor above [2].
Heo Seok-gyeong, the chief of the Incheon West Fire Station, provided details on the facility's safety zoning. He said that fire shutters were operational upon the department's arrival [1]. He said that fire compartments for areas equipped with sprinklers are typically divided into sections of 3,000 square meters [1].
Despite the adherence to these compartmentalization standards, the vertical nature of the mezzanine shelving may have bypassed the intended fire breaks. The combination of high ceilings and stacked combustible materials often creates a "chimney effect," which can push heat and flames upward more rapidly than sprinklers can suppress them [2].
“Fire shutters were operational upon the department's arrival.”
This incident highlights a critical tension between logistics efficiency and fire safety. As e-commerce giants utilize vertical mezzanine shelving to maximize storage in limited footprints, the resulting high-density combustible loads can outpace traditional sprinkler and shutter systems. The investigation may lead to revised safety regulations regarding the maximum height and density of shelving in South Korean logistics hubs.
