A FACT ABOUT CYLINDER.

I bet you didn't  knew about a fact of LPG cylinders. That it has an expiry date. Well a brilliant student name Shaini of take one school of mass communication writes an article, "a fact you didn't knew about cylinders "
She writes
" We all have been using LPG cylinders but approximately 80 % of the people are ignorant about a fact that it also has an expiry date like every consumable product. Generally while receiving that LPG cylinder most of the consumers are only focused on its weight and seal ignorant about its expiry date.  Nowadays,  LPG supplying companies are taking advantage of it by refilling the expired cylinder and further supply it to the consumer. This Is the main reason behind the accidents where LPG cylinder are responsible.
So how to check the expiry date.

there is ring on the top of the cylinder  to hold it and further three strips are connected to it.  The expiry date is printed on one of the three strips in which English alphabet letters A,B,C and D Are printed along with two numbers.
"A is for the first quarter of the year (January to march)
"B"is for second quarter of the year(April to June)
"C" is for third quarter of the year (July to September)
"D" is for the fourth quarter of the year (October to December)
And after that two numbers are printed along with that letter which signifies the year if expiry.

for instance, If A11 is printed on the cylinder than the expiry date of the cylinder is March 2011 and further usage of the cylinder will be harmful. The cylinder will likely become a bomb. In this situation consumer are suppose to refuse to receive such kind of cylinders and LPG supplying company get to be informed about it for prevention of any mishappenings"
