A: No there is no regulation or standard stating that but one
thing that you want to ensure is that the sticker being applied will not affect
the shell of the hardhat. Some stickers contain adhesives that may break down
the outer shell and reduce the original protection rating. It is recommended to
keep the stickers to a minimum so you can always see the shell and ensure that
it is still in good condition.
