Did you know that there is an expiry date (physical life) for LPG cylinders? Expired Cylinders are not safe for use and can cause lethal accidents.
Here is how you can check the expiry date of LPG cylinders:
On one of three side stems of the cylinder, the expiry date is coded alpha numerically which starts with A, B, C or D followed by a two digit number. e.g. D06.
The alphabets stand for quarters -
A for March (First Qtr),
B for June (Second Qtr),
C for Sept (Third Qtr),
D for December (Fourth Qtr).
The digits stand for the year till it is valid. Hence D-06 would mean December quarter of 2006.
So next time your delivery boy comes with a re-fill cylinder, make sure you check the expiry date. Many local LPG re-fillers even conceal the date, usually by pasting some sticker over it. So please be extra careful while checking
If you get a cylinder post expiry date, please return it back immediately, they are highly prone to leaking or bursting causing serious injuries and can even take life.
Although finding the expiry date is not hard at all if you know the trick, an average common man would almost never be able to decipher it. I wonder how difficult it is for the LPG companies to write something like "exp: Dec-2006" instead of such an alien code. Or may be they too want to conceal it?
