When it comes to oxygen cylinders, two independent deadlines must be distinguished: the technical inspection period for the pressurized gas container and the expiry date of the contained medical oxygen. Both pieces of information have different functions and should be checked separately in the operational control process.
Summary: TÜV Inspection and Shelf Life Compared
| Inspection Point | What is inspected? | What is decisive? |
|---|---|---|
| Technical Inspection Period | Pressurized gas cylinder / pressure vessel | Marking or inspection date on the cylinder body; for the oxygen cylinders we typically use, the inspection cycle is generally 10 years. |
| Oxygen Usability | Medical oxygen as a medicinal product | The expiry date indicated on the medicinal product labeling of the specific cylinder. Our fillings are regularly labeled with 35 months from the date of filling. |
Important: A valid technical inspection period does not extend the usability of medical oxygen. Conversely, a still valid expiry date for oxygen does not indicate whether the cylinder may be refilled.
Technical Inspection Period for Oxygen Cylinders
The recurring inspection concerns the pressurized gas container. The inspection date or the relevant marking is permanently affixed to the cylinder body. For the oxygen cylinders typically in our range, the technical inspection cycle is generally ten years; however, the marking on the specific cylinder and the regulation applicable to the container are always decisive.
For a refill, the cylinder must meet the applicable technical requirements. If a prescribed recurring inspection is due, it must be taken into account before further filling.
What to do if the inspection period is exceeded?
An exceeded inspection period does not automatically mean that an already filled cylinder must be emptied immediately in all cases. For portable pressurized gas containers, the relevant technical rules provide for further retention and emptying under certain conditions, including if an external visual inspection shows no irregularities. However, the specific assessment depends on the container, its condition, its labeling, and its operational use.
For a refill, on the other hand, the technical inspection period is of central importance. If you are unsure whether an existing cylinder can still be exchanged or refilled, you can send photos of the cylinder labeling in advance.
Usability of Medical Oxygen
Independent of the technical inspection period, medical oxygen as a medicinal product has its own expiry period. For the oxygen cylinders supplied by us, the specific expiry date is indicated on the medicinal product labeling of the respective cylinder. Our fillings are regularly labeled with an expiry period of 35 months from the date of filling; the date actually indicated on the cylinder is always decisive.
The labeling includes, among other things, batch information as well as information on filling and usability. Further information on the labeling of an oxygen cylinder can be found in our guide.
Consider Technical Inspection and Medicinal Product Labeling Separately
- Technical Inspection Period: concerns the pressurized gas container and in particular its refilling capability and safe operation.
- Expiry Date: concerns the contained medical oxygen as a medicinal product.
For professional users, it is therefore recommended to record both dates separately as part of regular inventory control. This prevents a technically flawless cylinder with unusable contents from being overlooked or a cylinder from being planned for filling even though a technical inspection is due.
What to do if TÜV or expiry date expire?
For suitable existing cylinders, we offer an oxygen cylinder exchange service as well as a refilling and supply service for medical oxygen. If a new cylinder is needed, you can find the available sizes and designs under Buy oxygen cylinder.
Frequently Asked Questions
How often must an oxygen cylinder be technically inspected?
For the oxygen cylinders we typically use, the inspection cycle is generally ten years. However, the marking on the specific cylinder and the regulation applicable to the respective pressurized gas container are always decisive.
Is medical oxygen shelf-stable for ten years if the cylinder has a ten-year TÜV inspection?
No. The technical inspection period of the cylinder and the usability of the medicinal product are independent of each other. For medical oxygen, only the expiry date indicated on the specific cylinder is decisive.
How long is the medical oxygen supplied by bluAqua usable?
Our fillings are regularly labeled with an expiry period of 35 months from the date of filling. The expiry date actually indicated on the delivered cylinder always remains decisive.
Can a cylinder with an expired technical inspection period be refilled?
A due prescribed technical inspection must be taken into account before a refill in accordance with the applicable requirements. Whether and what inspection is required depends on the specific container and its labeling.
