Knowing about the expiry date of Gas Cylinder

LPG gas is the most used cooking fuel in India and many other countries. Not only does it make your mother's kitchen work convenient, it is also a live bomb sitting just next to her almost all the time.
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. Using LPG cylinder post its expiry date can result in leakage that can also lead to an explosion. Once the cylinder is past the expiry date, one must stop using it. But most people have no idea how to check the expiry of the bottle. The steps to check the expiry are very simple and basic.
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. D-06.
The expiry of LPG Cylinder can be found on one of the metal strips that connect the body of the cylinder to top ring (handle). It is mentioned on the inner side of the strip. The strip has any of the alphabets from A to D painted on it along with a number. Decoding the expiry date is simple. The alphabet represents the month of expiry while the number indicates the year of expiry. A year is divided into four quarters –
  • A – January to March
  • B – April to June
  • C – July to September
  • D – October to December
Eg 1 : The digits stand for the year till it is valid. Hence D-06 would mean December 2006.
Eg 2 : If your cylinder has ‘A-18’ painted on the metal strip. The alphabet Arepresents month March, and 18 indicates the year 2018. So, a cylinder having A 18 mentioned on it means it will expire on March 2018. However, there is a limited grace period of three to four months after the expiry as the cylinder cannot be pulled out immediately out of the circulation.
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. There have been reports that distributors tamper with the expiry date as it is written with paint. So, please be extra careful while checking.
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.
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. So, next time you receive a cylinder do check the expiry date and stay safe.
