In the United States, the functions that EZ-SCREEN is intended
to perform are regulated by the Occupational Safety and Health
Administration (OSHA). Outside of the United States, these
functions are regulated by other agencies, organizations, and
governments. Whether or not any particular EZ-SCREEN
installation meets all applicable requirements depends upon
factors that are beyond the control of Banner Engineering Corp.
These factors include the details of how the EZ-SCREEN is
applied, installed, wired, operated, and maintained. It is the
responsibility of the purchaser and user to apply this
EZ-SCREEN System in full compliance with all relevant
applicable regulations and standards.
EZ-SCREEN can guard against accidents only when it is
properly installed and integrated into the machine, properly
operated, and properly maintained. Banner Engineering Corp.
has attempted to provide complete application, installation,
operation, and maintenance instructions. In addition, please
direct any questions regarding application or use of EZ-SCREEN
to the factory applications department at the telephone number
or addresses shown on the back cover.
In addition to OSHA regulations, several other organizations
provide information about the use of safeguarding devices.
Refer to the American National Standards Institute (ANSI),
the Robotics Industries Association (RIA), the Association for
Manufacturing Technology (AMT), and others (see below).
