Expiry date of gas cylinders

I got the email saying “expiry date of gas cylinders”. Then I search this from web at that time I sow this mail published in several WebPages (Blogs). And also I was able to find another article published in website, for your convenience I’m publishing this two article.
I report You decide.

Do you know that there is an expiry date (physical life) for LPG cylinders?
Most of us do not know this.
Expired Cylinders are not safe for use and may cause accidents.
In this regard please be cautious at the time of accepting any LPG cylinder from the vendor.
Here is how we can check the expiry of LPG cylinders:
On one of three side stems of the cylinder,
the expiry date is coded alpha numerically as follows
A or B or C or D and some two digit number following this 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 D06 would mean Fourth Qtr (December) of 2006.

CHENNAI: ‘Have you ever heard about LPG gas cylinder’s expiry date?’ Thus begins an email seeking to create awareness among consumers on the safe usage of domestic cooking gas cylinders.

The forwarded mail, which has been in circulation for about two weeks now, says that ‘expired’ cylinders are not safe to use and claims that it may cause accidents and explosion. It advises the consumers not to accept expired cylinders from the distributors.

The date of expiry is explained thus in the mail: ‘On one of three side stems of the cylinder, the expiry date is coded alpha numerically. While A stands for first quarter, B represents the second quarter, C the third and D the fourth quarter. The last two digits represent the year. Hence, D06 would mean that the date of expiry for that cylinder is December 2006.’

The mail also warns: ‘Please return the cylinder to the distributor if it had already expired as they are prone to leaks and may cause mishaps.’

Express sent the e-mails to top officials of the oil companies and sought their opinion.

Deputy General Manager (LPG), Indian Oil Corporation Limited, U V Mannur, said the word ‘expiry’ was misleading. “The date stenciled on the side stem of the cylinder refers to the due date for testing.

As per the Central Government guidelines, the cylinders are to be sent to the Controller of Explosives at Nagpur once in five years for mandatory safety test,” he said. This norm has been revised and cylinders could be sent once in ten years, the top official said, adding that every time the empty cylinders reach the plant, they are put to rigorous safety tests.

“There is absolutely no need for the public to break their heads over such things, as we stand guarantee for the safety of the products,” he added.

In his response, DGM-LPG, South Zone, Hindustan Petroleum Corporation Limited, K Radha Krishnan, said that all care was being taken at the plants to ensure that no ‘overdue’ cylinder goes into circulation. Regarding the mandatory testing, he too reiterated the views of the Indian Oil official.
