Live-Line Work Minimum Approach Distances
• Distances agree with OSHA
guidelines in Table R-6 of the
Federal Register published
1/31/94. These distances
take into consideration the
highest switching surge an
employee will be exposed to
on any system with air as the
insulating medium and the
maximum voltages shown.
• The clear live-line tool dis-
tance shall equal or exceed
the values for the indicated
voltage ranges.
*Avoid contact.
