ELECTRICAL HAZARDS
• This vehicle is not insulated and does not provide protection from contact or being
near electrical current. This includes lightning and lightning strikes.
• NEVER operate the vehicle in an area where overhead power lines, overhead
or underground cables, or other power sources may exist without ensuring the
appropriate power utility company de-energizes the lines.
• Always check for power lines before raising the deck.
• Look up and use light to search for power lines in the dark.
• Allow for vehicle movement and electrical line swaying.
• Do not step off or touch a charged vehicle.
• Maintain a clearance of at least 10 ft (3m) between any part of the vehicle from
any electrical line or apparatus carrying up to 50,000 volts. Refer to the Minimum
Approach Distance (MAD) chart. One foot additional clearance is required for
every additional 30,000 volts or less.
Minimum Approach Distance (M.A.D.)
Voltage Range
(Phases to Phase)
MINIMUM APPROACH DISTANCE
in Feet (Meters)
0 to 50KV
10 (3)
Over 50KV to 200KV
15 (5)
Over 200KV to 350KV
20 (6)
Over 350KV to 500KV
25 (8)
Over 500KV to 750KV
35 (11)
Over 750KV to 1000KV
45 (14)
NOTE: This requirement shall apply except where employer, local
or government regulations are more stringent.
• 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 truck. 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.
