As such, each of the doors 13 and explosion-proof parts 15 mentioned above is arranged at one end of the body 11 and the other end of the body 11, in particular using the lock member 21 of the door 13. By closing the door 13, it is possible to store dangerous goods such as a propellant that is accommodated inside the body 11, and also to transport dangerous goods such as a propellant.

However, the dangerous goods such as the propellant charged and received inside the body 11 may be burned or exploded inside the body 11 due to the surrounding environment, ambient temperature, external shock, and the like. If a dangerous object such as a propellant is burned or exploded in a state of being stored and stored inside the body 11, the body 11 itself may explode, and as a result, if a person is nearby, it may cause human injury. In particular, in the case where a plurality of dangerous goods storage devices 100 are stacked in the same space, a chain explosion may be caused.

Thus, in the present invention, by preventing the explosion of the body 11 itself by providing a dangerous material, such as the propellant, such as the explosion-proof part 15 is melted or crushed by the rise of the flame or gas pressure caused by an abnormal reaction. do. That is, in the present invention, the explosion prevention unit 15 is melted or crushed by an increase in the flame or gas pressure generated by an abnormal reaction such as a propellant, etc., which is referred to as opening the other end of the body 11. Since the flame or gas pressure can be discharged to the outside of the body 11, the body 11 itself can be prevented from being exploded even when dangerous substances such as a propellant charged and stored inside the body 11 abnormally react. It is.

Therefore, the explosion prevention unit 15 may be made of a material having a low melting point, a brittle material, or the like, in which dangerous goods such as propelling charges are melted or crushed by an increase in the flame or gas pressure generated due to an abnormal reaction. These may be used alone or in combination.

Examples of the material having a low melting point include an increase in flame or gas pressure generated during an explosion or explosion due to an abnormal reaction of a dangerous substance such as a propellant, before the body 11 itself burns or explodes, together with a dangerous substance such as a propellant.
