
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
Table 1-1. Minimum Approach Distances (M.A.D.)
Voltage Range (Phase to Phase)
MINIMUM APPROACH DISTANCE in Feet
(Meters)
0 to 50 KV 10 (3)
Over 50KV to 200 KV 15 (5)
Over 200 KV to 350 KV 20 (6)
Over 350 KV to 500 KV 25 (8)
Over 500 KV to 750 KV 35 (11)
Over 750 KV to 1000 KV 45 (14)
NOTE: This requirement shall apply except where employer, local or governmental
regulations are more stringent.

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 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 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 (MAD). ASSUME ALL ELECTRICAL PARTS AND
