The helmet is new on the outside, but worn out on the inside! Know after how many years it should be replaced

Bike or scooter riders are required to wear helmets. Despite this, many people wear helmets just to avoid currency. This is the reason why after buying a helmet, we keep using it until it breaks. But did you know that even helmets have a fixed age? An old helmet that looks great on the outside may fail to protect the head during an accident. Therefore, it is important to know how often the helmet should be changed.

For how many years can the helmet be used?

According to safety experts and many major helmet companies, good and ISI certified helmets should generally be replaced after 3 to 5 years of purchase. Famous Japanese helmet companies Arai and Shui also offer similar advice regarding the age of helmets.

According to Arai guidelines, even if the helmet is brand new and has never been used, its warranty and safety capability expires after completion of 7 years from the date of manufacture. This means that keeping the helmet unused for a long time is also not a way to extend its life.

Why does a helmet deteriorate even though it looks perfect on the outside?

Often people think that when there is no crack or wear in the helmet, then what is the need to replace it. But its real security does not depend only on the outer shell. Inside the helmet is a special white thermocouple-like layer, called the EPS foam liner. It plays an important role in reducing the blow to the head during an accident.

During regular use, sweat, hair oil, dust and moisture gradually degrade this foam. Over time it hardens and shrinks. In such a situation, in case of an accident, its ability to absorb shock is reduced. Additionally, UV rays from constant exposure to sunlight can also weaken the outer shell of the helmet.

Replace the helmet immediately under these circumstances

There are some situations in which one should not wait for 3 to 5 years to complete. If your helmet has been involved in a road accident or has fallen from a height and hit a concrete floor hard, it is better to replace it. Even if no marks are visible on the outside, the EPS foam inside can be damaged.

Also, if the helmet starts to loosen on the head or slips out of place when moving the head, buy a new helmet. During an accident, a loose helmet may come off the head and you may not get the protection you need.
