    Old motorcycle helmets

    Any idea what I can do with old motorcycle helmets? Seems such a waste to just throw them away. In the US I donated them to emergency services for them to practice rescues. I wonder if they will take them in Hong Kong…

    Leave them beside a bin, if there’s a use or a market for then, someone will take it.

    Helmets should be replaced every 5-10 years depending on use. Some even say 3 years.

    Do the responsible thing and destroy it.

    Its the same with very old heaters. You may be tempted to give them to charity, but what you’re doing is actually giving a fire hazard to a poor person who likely already is living in a hazardous living environment.

    I would be a bit dubious as to this claim, which I have seen repeated for bicycle helmets on many internet articles without research backing. If these things incorporate EPS foam, that stuff certainly lasts for more than 3-5-10 years and is highly resistent to salt from sweat. The other concern might be UV degradation of the outer shell, but that stuff is also made to be highly UV resistant.

    A snippet regarding bicycle helmet testing (much lighter construction than motorcycle helmets): Extensive testing of used (but not crashed) bicycle helmets shows that the foam liners retain their performance over many years. MEA Forensic announced at a May ASTM F08.53 technical meeting the results of their testing of 675 bicycle helmets, some as old as 26 years. "There is no justification for two to ten year replacement recommendations based on impact performance," said MEA's Alyssa DeMarco.

    My suspicion of the rapid replacement recommendation for helmets is a mix of manufacturers doing a CYA exercise, and encouraging resales.

    I am certainly one to lean onto the sinister resales reasoning. Without reading into it and simply knowing MY usage of motorcycle and bicycle helmets, mainly how often it falls or is pressed against other objects, I replaced every so often (~5 years). Daily usage.

    I would still not suggest using a secondhand helmet. Considering a nice motorcycle helmet for $800 is but half of annual insurance and that even 20 year old motorbikes cost 10,000+, I wouldn’t be convinced financial difficulties are paramount to use a secondhand helmet.

    With good care (storage) / less usage, a helmet likely could last a lifetime, yes.
