Most of us do not know this. Do you know that there is an expiry date (physical life) for CNG cylinders? Expired Cylinders are not safe for use and may cause accidents. In this regard please be cautious at the time of accepting any CNG cylinder from the vendor.
Here is how we can check the expiry of CNG 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 - June (Second Qtr), C-Sept
(Third Qtr), D for December (Fourth Qtr). The digits
stand for the year till it is valid. Hence D06 would
mean December qtr of 2006.
This Information may save life of many people and create Public awareness.
