Electrocution Hazards
•
This machine is not insulated and does not provide protection
from contact or proximity to electrical current.
•
Maintain distance from electrical lines, apparatus, or any ener-
gized (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 (3 m) 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 work-
ing 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 ener-
gized equipment.
DO NOT MANEUVER MACHINE OR PERSONNEL INSIDE PROHIBITED ZONE (MAD). ASSUME
