Beware of expiry date
LPG cylinder has an expiry date. Expired cylinders are not safe for use and many cause accidents. Be cautious at the time of accepting any LPG cylinder from the vendor.
Here is how we can check the expiry date of a LPG cylinder: on one of the three side stems of the cylinder, the expiry date is coded as –A or B or C or D, followed by some two-digit number, for e.g. D 11. The alphabet stands for different quarter of the year, i.e. A for 1st quarter; B for 2nd quarter; C for 3rd quarter and D for 4th quarter. The digits stand for the year. Hence, D06 means the cylinder has a life up to December, 2011.
Tyres too have an expiry date:
Vehicle tyres have a 4-year validity period from their Date Of Manufacture (DOM). Now, how to find out the expiry date of a tyre? One may check for a stamp like this on the tyre (*2611*). There is an asterisk at the beginning and at the end of this serial number. The first two numbers represent the week of the year in which the tyre was manufactured. In this example, 26 represents the 26th week of the year. The subsequent two numbers represent the year. In this example, 11 represents the year, 2011. That means the tyre was manufactured in the 26th week of 2011.
Check all your tyres for safety purposes. Do not use tyres which are more than 4 years old. They are likely to burst because the rubber component may have hardened and cracked.
I gained this knowledge after a bitter experience for neglecting the expiry date of tyres.
So, let us beware of expiry dates!
