Description

TECHNICAL FIELD The present invention relates to a dangerous goods storehouse for storing dangerous goods defined by the Fire Service Act.

When storing more than the specified amount of hazardous materials under the Fire Service Law, it is necessary to store them in a hazardous materials storage that meets the standards of various laws and regulations.

Hazardous materials under the Fire Defense Law are classified into Classes 1 to 6 according to their types. In order to store a certain amount (for example, 1/5 to 10 times the specified amount) of a flammable and volatile liquid such as a must be stored in a designated hazardous materials store.

Food additives such as flavorings are also chemical substances, so they may be subject to regulations for hazardous materials under the Fire Service Law. Furthermore, some raw materials for pharmaceuticals and cosmetics, such as alcohol, are classified as dangerous substances under the Fire Defense Law, and must be stored in hazardous substance storage.

Hazardous material storage can be constructed as a building with a concrete structure at the installation site, but in the case of relatively small-scale storage of 1/5 to 10 times the designated quantity, the floor area is 1 tsubo or more. Steel-frame structures with a size of about 3 tsubo are in widespread use. In the factory, this steel-framed storage for hazardous materials is first formed by welding or other means to form a framework of steel-framed parts, then steel plates are attached to the floor, ceiling, and walls, and the necessary equipment (exhaust fans, lighting, etc.) is attached. produced by Then, after being produced as a finished product in a factory, it is transported to an installation site and installed at a predetermined position. Factory production limits the size that can be transported, but ensures stable quality, shortens the construction period, and reduces costs.

In addition, although a structure in which the floor has a concrete structure has been proposed (for example, Patent Document 1 and Patent Document 2), even in this structure, after being produced in a factory, it is transported by truck and installed at the installation position. .

Furthermore, instead of factory production, by assembling parts such as floor units, wall panels, and ceiling units at an indoor installation location, a dangerous goods storage is completed and installed indoors (Patent Document 3) ). There is also proposed a hazardous material storage facility with a built-in jib crane that enables easy and safe loading and unloading of stored items that are too heavy to be lifted by human power (Patent Document 4).
