Cables
Make sure your cables are out of the way of performers, production crew, and audience so
they will not trip over them.
Sound Level
Permanent hearing loss may be caused by exposure to extremely high noise levels. The U.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.
