SECTION 1 - SAFETY PRECAUTIONS
• The minimum approach distance may be reduced if insulat-
ing barriers are installed to prevent contact, and the barri-
ers are rated for the voltage of the line being guarded.
These barriers shall not be part of (or attached to) the
machine. The minimum approach distance shall be reduced
to a distance within the designed working dimensions of
the insulating barrier. This determination shall be made by
a qualified person in accordance with the employer, local,
or governmental requirements for work practices near
energized equipment.
DO NOT MANEUVER MACHINE OR PERSONNEL INSIDE PROHIBITED ZONE
(M.A.D.). ASSUME ALL ELECTRICAL PARTS AND WIRING ARE ENERGIZED
UNLESS KNOWN OTHERWISE.
