CAUTION! Permanent hearing loss may be caused by exposure to extremely high noise levels. The U.S.
Government's Occupational Safety and Health Administration (OSHA) has specified permissible exposures to certain
noise levels.
According to OSHA, exposure to high sound pressure levels (SPL) in excess of these limits may result in hearing
loss. When using equipment capable of generating high SPL, use hearing protection while such equipment is under
operation.
