[Case Study] Heiki Shipping Co., Ltd. <Explosive Structure>

The installation of a "ceiling" necessary for temperature management is not possible. A solution has emerged by focusing on the on-site environment.

We would like to introduce a case study of problem-solving at Heiki Kaiun, which has newly entered the hazardous materials warehouse industry that requires special structures and strict constraints. The basic structure of a hazardous materials warehouse is designed to allow explosions to vent from the roof. When temperature control is necessary, the installation of "ceiling insulation panels" is effective, but it is rare to obtain installation permission under the Fire Service Act. Therefore, we approached the solution with a "ceiling installation." Focusing on a site facing the sea with few adjacent buildings and pedestrian traffic, we proposed a "lateral" explosion venting structure that directs the explosion away from the door. By reducing the risk of accident induction through "the width of the retained open space" and ensuring that the explosion direction is towards the wide area of the site and the sea, and further designing the door as an explosion venting structure, we were able to obtain approval from the fire department based on strength values. 【Case Overview】 ■ Issue: Explosion venting structure ■ Solution: Door explosion venting structure that meets special conditions ■ Industry: Transportation and warehousing ■ Warehouse Type: Hazardous materials warehouse, temperature-controlled warehouse ■ Stored Materials: Hazardous materials *For more details, please download the PDF or feel free to contact us.
