The question is, "Does a gas cylinder have an expiration date?
You are humbly welcome to the Ghana Media Trend desk. In this article, we will take you through some steps to know the facts about gas cylinders.
As the question was already asked above
Yes, gas cylinders have an expiry date. While the metal cylinder itself does not expire, its safety and usability are subject to periodic inspections and certifications.
Check the Validity
The lifespan of a gas cylinder varies depending on the manufacturer and the regulations in your country, but it is typically between 10 to 15 years from the date of manufacture.
Most LPG (liquefied petroleum gas) cylinders have a test date stamped on the metal, indicating when they should be re-tested for safety.
How to Check the Expiry Date:
1. Look for the Date Code—On the metal body of the cylinder, you will find a set of letters and numbers, typically on the collar or handle.
2. Deciphering the Code/Marking Code—The date is often written in a format like A-25, B-26, C-27, or D-28, where:
- A, B, C, and D represent quarters of the year (A = Jan-Mar, B = Apr-Jun, C = Jul-Sep, D = Oct-Dec).
- The number (e.g., 25, 26, 27, etc.) represents the year when the cylinder needs retesting.
OR
The letters represent quarters of the year:
- A → January to March
- B → April to June
- C → July to September
- D → October to December
For example, B-26 means the cylinder is due for inspection in April-June 2026. If a cylinder is used beyond its test date without re-inspection, it may become unsafe.
OR
The number represents the year (e.g., "24" means 2024).
What Happens After Expiry? / Why Does It Matter?
The cylinder should be sent for testing and recertification.
If found unsafe, it is decommissioned or replaced.
Using expired cylinders can be dangerous due to the following reasons below;
Expired cylinders can become weaker and prone to leaks, cracks, or explosions. If your cylinder is past its test date, it should be inspected and recertified by an authorized gas supplier.
NOTE: Always check the test date before using or refilling a gas cylinder for safety
