Safety Precautions
Table 1. Minimum Approach Distances (MAD) (continued)
Voltage Range (Phase to Phase)
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 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 MAD 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 MAD 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 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 wiring are energized unless known otherwise.
1.3.4 Tipping Hazards
• Ensure that the ground conditions are adequate to support the maximum tire load
indicated on the tire load decals located on the chassis adjacent to each wheel. Do
not travel on unsupported surfaces.
• The user must be familiar with the operating surface before driving. Do not exceed
the allowable side slope and grade while driving.
• Do not elevate platform or drive with platform elevated while on or near a sloping,
uneven, or soft surface.
