We have 4 areas on site that have potential to exceed 80dBA. Not on a regular basis but often enough to think about it.
We've given all operators in the areas training of effects of excessive noise on hearing and they have selected appropriate PPE but want to put some sort of display in the areas to indicate to the operators when the noise gets to potential damaging level so they know to wear hearing protection.
I'm really struggling to find a noise display that is suitable!
Any suggestions would be greatly received!
PS, Engineering and Admin controls already considered and acted upon
