Storage of high-pressure gas

Do not take a high-pressure gas cylinder into a sealed room. If you must do so by necessity, please install necessary devices such as a ventilation system and an oximeter.
For specialty gases, additional procedures (JASRI's procedures or legal procedures) are required. Please fill in form² and contact the Safety Office. The cylinder cannot be transported into the facility until a permit is acquired.
For flammable gas, toxic gas and oxygen gas, legal technical standards must be fulfilled. Please provide the necessary information³ to Safety Office and satisfy the technical standards before high-pressure cylinders containing such gases are transported into the facility.

The Storage Ring Building and Storage Ring Annex West (hereafter called Storage Ring Buildings) have been registered with the government as places where high-pressure gas is stored. Therefore, high-pressure gas cylinders that do not fulfill the requirements cannot be brought into these buildings.

When new high-pressure gas cylinders are brought into the buildings or the storage conditions are changed, fill in High-pressure gas storage request (the Storage Ring Buildings) (pdf format) or High-pressure gas storage change request (the Storage Ring Buildings) (pdf format), respectively, and submit them to the head of the Safety Office.

The outline of the procedures, which take approximately 1 month, is as follows.

Applicants -> The head of the Safety Office -> Executive head of JASRI -> Prefectural governor
-> Granted permission to transport and store high-pressure gas cylinders

Radiation beam users who transport high-pressure gas cylinders into the buildings temporarily⁴ are requested to fill in High-Pressure Gas Cylinder Temporary Installation Confirmation and Report (pdf format, both sides), and submit it to the head of the Safety Office through the User Administration Division.

General persons are people other than radiation beam users, including the staff of JAEA(Japan Aomic Energy Agency), RIKEN, JASRI, University of Hyogo and contract beamlines, gas suppliers and contractors.

General persons transporting high-pressure gas cylinders for temporary installation⁵ must fill in High-Pressure Gas Cylinders Temporary Installation Confirmation and Report (general persons) (pdf format) and submit it to the head of the Safety Office through the person in charge⁶.

Special application is not required for transporting high-pressure gas cylinders (except specialty gases, flammable gases, toxic gases, and oxygen gas) into buildings other than the Storage-Ring Buildings. The cylinder manager shall be in charge of the safe storage of the cylinders.

To transport high-pressure gas cylinders into buildings administrated by JAEA, RIKEN, and University of Hyogo, follow each instruction.

The Safety Office will examine the number of stored high-pressure gas cylinders annually (planned at the beginning of December). Cylinder managers should fill in Questionnaire for Stored High-Pressure Gas Cylinders Quantity Inspection (compressed gas cylinders)" (pdf format) and submit it to the Safety Office. Details will be provided at the implementation of the examination.

The cylinder manager must keep records such as Inventory of high-pressure gas cylinders. In the event of a change of the cylinder manager, the invetory records must be taken over by the new manager. These records must be shown during the regular inspection or on-site inspection by the prefectural government or fire department. The records must be kept until the regular inspection or on-site inspection by the prefectural government.
