SECTION 1 - SAFETY PRECAUTIONS
3121230 – JLG Lift – 1-5
Electrocution Hazards
• This machine is not insulated and does not provide protec-
tion from contact or proximity to electrical current.
• Maintain distance from electrical lines, apparatus, or any
energized (exposed or insulated) parts according to the
Minimum Approach Distance (MAD) as shown in Table 1-1.
• Allow for machine movement and electrical line swaying.
• Maintain a clearance of at least 10 ft. (3m) between any part
of the machine and its occupants, their tools, and their
equipment 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.
• 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
Table 1-1. Minimum Approach Distances (M.A.D.)
