HEARING LOSS
Sandblasting injuries are not always a direct result of the dust. Sandblasting is an extremely loud activity. Hearing loss is a real possibility for blasters and many already suffer from it. Even though blasters wear hoods, it is still important to wear earplugs. This is even more important when blasting inside enclosed spaces like tanks where much blasting takes place.
