1.3 OPERATION SAFETY
Electrical Hazards
• This machine is not insulated and does not provide protection from contact or
proximity to electrical current.
• Maintain safe distance from electrical lines, apparatus or any energized
(exposed or insulated) parts according to the Minimum Safe Approach Distance
(MSAD).
• 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 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 safe 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 safe 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.
