How long is the life of a safety helmet?
It depends on the material used for the helmet (the use of the helmet is calculated from the day the product is manufactured):Woven sticks of plant sticks, no more than two years.Plastic cap, paper glue cap, not more than two and a half years.Glass steel (vinylon steel) rubber cap is more than three and a half years.More than necessary to do testing, testing qualified can continue to use, but then still have to be tested regularly.
After the expiration of the term of use of the safety helmet, the unit concerned must go through the spot check test to the relevant departments, and may continue to use it after qualified, otherwise the batch of helmets will be scrapped.
The use of helmets should pay attention to the use of the deadline and the conditions for the abolition. The use of plastic safety helmet is 3 years, and the use period of FRP helmet is 2 and a half years
Preferably two years a change, after all, helmet is consumable, no one can know the exact expiration time, safety or in the first place!
