Electrocution Hazards; Minimum Approach Distance (M.a.d.) - JLG Toucan 8e Operation And Safety Manual

Electrocution Hazards

• This machine is not insulated and does not provide pro-
tection 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.

SECTION 1 – SAFETY PRECAUTIONS
Table 1-1. Minimum Approach Distance (M.A.D.)
Voltage Range
(Phase to Phase)
0 to 50 kV
Over 50 kV to 200 kV
Over 200kV to 350 kV
Over 350 kV to 500 KV
Over 500 kV to 750 kV
Over 750 kV to 1000 kV
NOTE: This requirement shall apply except where employer,
local or governmental regulations are more stringent.
• Maintain a clearance of at least 3 m (10 ft.) 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. A 0,3 m (1 ft.) additional clearance is
required for every additional 30 000 volts or less.
• The minimum approach distance may be reduced if insu-
lating barriers are installed to prevent contact and the bar-
riers 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 dimen-
sions of the insulating barrier. This determination shall be
