At home, we might have noticed a letter and number marked on the gas cylinder, but often we overlook it. This marking has an important meaning—it shows the due date for the cylinder’s periodic safety check.
The letter represents the quarter of the year:
A – January to March
B – April to June
C – July to September
D – October to December
The number next to the letter indicates the year.
For example, “B25” means the cylinder is due for safety testing between April and June 2025.
So, next time you receive a gas cylinder, take a moment to check the marking. It’s a small step that helps ensure your safety at home.
