Most people using cooking gas do not that their gas cylinder has an expiry date. When a gas cylinder expires, it results in leakage and this can cause an explosion which may eventually lead to loss of lives and properties.

According to a State Coordinator, Standard Organisation of Nigeria [SON], Joseph Ugbaja, “If a cylinder of 12kg explodes, it is capable of bringing down a two-storey building. Cooking gas cylinders must not exceed five years.” According to the SON Director, most people using gas cylinders hardly remember when it was bought. Once the cylinder is past the expiry date, one must stop using it. But most people have no idea how to check the expiry date of the cylinder. 

To check the expiry date of your LPG cylinder, follow this process:

Here is how to verify the expiry date of the LPG cylinder. The expiry of the LPG Cylinder can be found on one of the metal strips that connect the body of the cylinder to the top ring (handle). It is painted on the inner side of the strip with any of the alphabets from A to D along with a number. It is written like a code but decoding the expiry date is simple. The alphabet represents the month it expires while the number indicates the year.

A year is divided into four quarters –

  • A – January to March
  • B – April to June
  • C – July to September
  • D – October to December


For example, this cylinder has a ‘B 13′ painted on the metal strip. Alphabet B represents the month of June and 13 indicates the year 2013. So a cylinder having B 13 painted on it means it will or already expired in June 2013.

However, after the expiry date, there is a limited grace period of three to four months as the cylinder cannot be pulled out immediately out of the circulation. There have been reports on how distributors tamper with the expiry date as it is written with paint. So, when next you purchase or receive a gas cylinder, do check the expiry date to avoid “stories that touch the heart”. Please, stay safe.

Thanks, Amira for this timely information, with all the explosion going on lately and the unnecessary loss of lives, I will definitely go and check my cylinder now.

Thanks for sharing this knowledge, it would go a long way to reduce gas explosions arising from the usage of expired gas cylinders.

I think information such as this should be given to all cylinder sellers so that they can educate buyers.
