⚠️ ALWAYS Check This Code on Your LPG Gas Cylinder!
Most people think LPG cylinders have an “expiry date” ❌
But that’s not actually true.
LPG gas cylinders do NOT have a fixed expiry date for the steel cylinder itself.
What you see on the cylinder is a 👉 **Statutory Testing Due Date**.
Every LPG cylinder is periodically tested for safety.
Only if it passes the inspection, it is allowed to be refilled and used again.
🔍 How to Read the Code?
Example: **D-28**
✅ Letter = Quarter of the Year
A → Jan, Feb, Mar
B → Apr, May, Jun
C → Jul, Aug, Sep
D → Oct, Nov, Dec
✅ Number = Year
28 means 2028
So 👉 **D-28** means the cylinder is due for mandatory safety testing between October and December 2028.
📍Where is this code written?
It is usually painted on one of the vertical metal strips/stays connecting the top ring to the cylinder body.
⚠️ Important:
If the due date has passed, the cylinder should ideally undergo testing before further use/refilling.
If it passes the test, a new due date is marked.
If it fails, the cylinder is scrapped.
✅ Whenever gas delivery arrives:
✔️ Check the seal
✔️ Check for leakage smell
✔️ Verify the Test Due Date code
Safety first 🙌
