6.

Exposure to extremely high noise levels may cause permanent

hearing loss. Individuals vary considerably in susceptibility to

noise-induced hearing loss, but nearly everyone will lose some

hearing if exposed to suciently intense noise for a period of

time. The U.S. Government’s Occupational Safety and Health

Administration (OSHA) has speciﬁed the permissible noise

level exposures shown in the following chart.

According to OSHA, any exposure in excess of these

permissible limits could result in some hearing loss. To

ensure against potentially dangerous exposure to high sound

pressure levels, it is recommended that all persons exposed

to equipment capable of producing high sound pressure levels

use hearing protectors while the equipment is in operation.

Ear plugs or protectors in the ear canals or over the ears must

be worn when operating the equipment in order to prevent

permanent hearing loss if exposure is in excess of the limits set

forth here:
