SECTION 1 - SAFETY PRECAUTIONS
31217162 1-5
Electrocution Hazards
• This machine is not insulated and does not provide protection
from contact or proximity to electrical current.
• Maintain safe clearance from electrical lines, apparatus, or any
energized (exposed or insulated) parts in accordance with the
Minimum Approach Distance (MAD) as specified in Table 1-1.
• Allow for machine movement and electrical line swaying.
• Maintain a clearance of at least 10 ft (3 m) between any part of
the machine and its occupants, their tools, and their equip-
ment from any electrical line or apparatus carrying up to
50,000 volts. One foot additional clearance is required for
every additional 30,000 volts or less.
• It is not recommended to use the machine during lightning. To
prevent injury or machine damage if lightning occurs during
operation, lower the platform and shut down the machine in a
safe and secure location.
• The minimum approach distance may be reduced if insulating
barriers are installed to prevent contact, and the barriers are
rated for the voltage of the line being guarded. These barriers
shall not be part of (or attached to) the machine. The mini-
mum 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 with
respect to electrical transmission and distribution in accor-
dance with the employer, local, or governmental requirements
for work practices near energized equipment.
DO NOT MANEUVER MACHINE OR PERSONNEL INSIDE PROHIBITED ZONE (MAD). ASSUME
ALL ELECTRICAL PARTS AND WIRING ARE ENERGIZED UNLESS KNOWN OTHERWISE.
