Next time when cylinder is dropped at your place, do not hesitate to check the Expiry Date! Attached picture is of the expired Cylinder of my home! You have learnt something today! Isn't it!
Very good info mals, thanks for sharing! I have not observed this till now but why does they supply expired cylinders :confused2: don't they know its dangerous?
Dear Mals, very valuable information.....:2thumbsup: thanks for sharing. will check mine after getting back home. love, Anu
Hi Seno, Normally they do not, my cylinder's expiry date was at the end of this month, but my cylinder got empty before that itself. When they supply cylinders they keep 2 months min margin of expiry date, but it is always safe to check! Isn't it!
Hi Anu, I was so excited, that I ran to my cylinder to check where it is written, all these years I never knew that these numbers meant expiry date. Ooooppps!
