If you want to make any change on the gas storage condition, submit these documents at least 30days prior to the first day of the cycle concerned.
Applicant → safety office manager → director general → prefectural governor → [approval of delivery (storage) of high pressure gas container]
Delivery of High Pressure Gas Container to Other Places than “Storage Ring Facility etc.”
When storing a high pressure gas container in another building within the jurisdiction of JASRI than the “Storage Ring Facility etc.”, the “Application for approval of storage of high pressure gas (other than Storage Ring Facility)” and “Application for approval of changes in storage of high pressure gas (other than Storage Ring Facility)” must be submitted. It is necessary to keep an inventory of each building.
Regarding the delivery of high pressure gas container to the buildings managed by Japan Atomic Energy Agency (JAEA), RIKEN, and University of Hyogo, consult each institution.
Person in Charge of Gas Containers
Before delivering a high pressure gas container, assign a person in charge of management of gas containers.(Note 1)
(Note 1) As a general rule, the person in charge of the management of gas containers should be a person in charge of beamline (manager) for beamline, and a person in charge of the fire management for other laboratories. Total amount of all cylinders at the site should be grasped by a person in charge of the site. If it is difficult to assign the person in charge of beamline and the person in charge of fire management as the person in charge of the management of gas containers, other personnel can be assigned. Make sure to comply with the storage amount specified for a “storage place for a high pressure gas container.”
The person in charge of the management of gas containers is responsible for the security control of the high pressure gas containers.
Receipt and Delivery of Containers
The person in charge of the management of gas containers must manage the receipt and delivery of the gas containers, using “The Ledger for receipt and delivery of high pressure gas containers”. It is acceptable for the contractors who deliver the gas container to enter the ledger; however, a confirmation seal (signature) of the person in charge of the management of gas containers is necessary.
The Ledger for receipt and delivery of high pressure gas containers should be attached in a visible position near the container.
Handling of High Pressure Gas Containers
1) Store the high pressure gas containers (gas cylinders) in the storage place for high pressure gas containers. (Do not store on a cart for delivery.)
2) Always keep a tool to open and close the container (prescribed tool) in the facility where the high pressure gas containers are stored and used.
3) Attach a sign of open/close on a high pressure gas container that is in use.
4) Inspect daily.
5) Regarding containers that are not in use, filled and empty containers must be stored separately. Attach an “empty”(Note 2) sign to the empty containers.
(Note 2) Stickers stating “filled” and “empty” are attached by the contractors to the gas containers purchased by JASRI. Use these stickers to indicate whether the container is “filled” or “empty.”
6) Make sure to cap the container when not in use and during transfer.
Refer to the “Guideline for the handling of high pressure gas containers” of JASRI.

Return of High Pressure Gas Containers
The empty gas containers must be returned to the contractors as soon as possible.
The maximum storage period of high pressure gas containers at JASRI is one year. Containers that are stored at JASRI for longer than one year must be returned to the contractor, even if they are still filled.
Retention of Records
The person in charge of the management of the gas containers must retain the records such as “The Ledger for receipt and delivery of high pressure gas containers”.
When the person in charge of the management of gas containers is changed, make sure that the ledger is handed over.
These records may be presented at the regular and on-the-spot inspections by the prefecture or fire department.
Delivery by Users (Radiation Work Users)
When radiation work users deliver the high pressure gas containers to the storage place, enter the necessary information in the “Pre-application for delivery of high pressure gas container (for radiation users)”, and apply to the Safety Office Manager via SPring-8 Users Office.
Temporary Delivery (General Personnel)
Temporary Delivery (General Personnel)
General personnel include manufactures who deliver the high pressure gas containers for the purpose of other than research and construction workers.
When the general personnel deliver high pressure gas containers on a temporary basis(Note 5), enter the “Application for “temporary” delivery of high pressure gas containers (general)” and submit it to the Safety Office Manager via the person in charge(Note 6).
(Note 5) As a general rule, the delivery period is one week or less. Obtain permission from the Safety Office beforehand, if it is unavoidable for the period to exceed one week due to construction or work.
(Note 6) The person in charge is a staff member of JASRI or the contract beamline (including RIKEN beamline) who brought in the high pressure gas container directly or indirectly.
A standard for acetylene consumption is in place.

Handling of Ultra low Temperature Liquid Gas
Ultra low temperature liquid gases include liquid nitrogen, liquid helium, liquid oxygen, and liquid argon. In this section, liquid nitrogen, which is often used in various experiments, is discussed.
Among the ultra low temperature liquid gases that are used at SPring-8, liquid nitrogen is most frequently used in various experiments for the purpose of cooling and substitution. Therefore, the places where users obtain liquid nitrogen as needed are provided within the facility. There are 5 places in Storage Ring Facility Experiment Hall and 1 place in Medium-length Beamline Facility Building.
Before obtaining liquid nitrogen at these places, contact SPring-8 Users Office (Ext. 2225) and watch the training video regarding “handling of ultra low temperature liquid gas.”
Safety measures
‹Precautions concerning low temperature›
Because of its extremely low temperature of -196°C, liquid nitrogen may cause frostbite if it is spilled on the body.
Especially if a large amount of liquid nitrogen is poured on gloves or clothing, it becomes impossible to remove the gloves or clothing, resulting in severe frostbite. Therefore, it is necessary to wear special gloves for low temperature work and to not expose the skin.
‹Precautions for oxygen deficiency and explosions›
Liquid nitrogen evaporates and expands in the order of approximately 650 times its liquid volume. If the vents of the experimental equipment, through which evaporated liquid nitrogen is supposed to escape, are clogged, the piping and sealed container can explode due to elevated pressure. Therefore, proper measures such as providing safety valves should be taken. Be aware of the possibility of oxygen deficiency, when using liquid nitrogen in a small space.
Keep the room in which liquid nitrogen is used well ventilated. Take measures such as installing oxygen monitors to prevent oxygen deficiency, if needed.
