Actually, there isn’t any expiry date written on the helmet at all.
You have to calculate the date based on the manufacturing date that is etched on the helmet.
According to the general rule, all safety helmets need to be replaced after 3 years of usage.
However, if there is any wear & tear or damage, you should replace it immediately.
Where to find the expiry date
The tricky point is that the date isn’t etched or engraved like normal, it is done in a rather different manner.
Instead of the regular stickers, the manufacturing stamp is raised plastic that you will find on the inside of the helmet, right in the centre.
It is in a clock form that is very easy to read.
Here is how you can read the manufacturing stamp;
- Identify the stamp, it is similar to a clock face, with numbers 1-12 spread along its perimeter.
- The number represent the month of manufacture. For example, 1 is for January and 12 is for December.
- The arrow points at the month the helmet was manufactured in. If it is pointed at 3, it means it was manufactured in march.
- The year is stamped in the centre of the clock-like figure. If it says 15 in the center, it means your helmet was made in March 2015.
- Based on this you can calculate the expiry date of your helmet like in the above case, the hard hat expired in march 2018.
It is necessary to mention that there could be a different way the dates are stamped in different countries but the above one is the standard procedure in most countries.
