When normally enclosed live parts are exposed for maintenance or repair, they must be guarded to protect unqualified persons from contact with the live parts. - (2) Alerting techniques . You must use the following alerting techniques to warn and protect employees from hazards which could cause injury due to electric shock, burns, or failure of electric equipment parts: - (a) Safety signs and tags . You must use safety signs, safety symbols, or accident prevention tags where necessary to warn employees about electrical hazards which may endanger them. - (b) Barricades . You must use barricades in conjunction with safety signs where it is necessary to prevent or limit employee access to work areas exposing employees to uninsulated energized conductors or circuit parts. Conductive barricades may not be used where they might cause an electrical contact hazard. - (c) Attendants . If signs and barricades do not provide sufficient warning and protection from electrical hazards, you must station an attendant to warn and protect employees. - (3) Design requirements .

If work is to be performed near overhead lines, you must deenergize and ground the lines, or provide other protective measures before work is started. If the lines are to be deenergized, you must make arrangements with the person or organization that operates or controls the electric circuits involved to deenergize and ground them. If protective measures, such as guarding, isolating, or insulating, these precautions must prevent employees from contacting such lines directly with any part of their body or indirectly through conductive materials, tools, or equipment. - (6) Unqualified persons . When an unqualified person is working in an elevated position, or on the ground, near overhead lines, the location must be such that the person and the longest conductive object he or she may contact cannot come closer to any unguarded, energized overhead line than the following distances: - (a) For voltages to ground 50kV or below--10 ft.; - (b) For voltages to ground over 50kV--10 ft. plus 0.4 inch for every 1 kV over 50 kV. - (7) Qualified persons .

## ELECTRICAL POWER LINES Keep a safe distance from electrical power lines. Never approach power lines with any part of the machine and its load unless all local and national required safety precautions have been taken. Electrocution and death can result from arcing, touching or even being close to a machine that is in contact with or near an electrical source. - · Maintain the maximum possible distance from power lines and never violate the minimum clearance. - · Always contact the nearest electric utility and determine jointly what specific precautions must be taken to ensure safety. - · Consider all lines to be power lines and treat all power lines as energized even though it is known or believed that the power is shut off and the line is visibly grounded. - · Use a signal person to observe the approach of any part of the machine or load to the power line. - · Caution all ground personnel to stand clear of the machine and the load at all times. - · If the machine should come in contact with a live electrical source, do not leave the operator's seat. Do not allow anyone to approach or touch the machine. - · Observe the applicable rules or regulations for clearance distances for power lines and other electrical equipment for the country where the machine is operating. Always maintain the following clearances when operating near high voltage power lines. <!-- image --> The reference of the safe distances from high voltage cables are as follows. ## WORKSITES IN URBAN AREAS Set up barricades to prevent unauthorized personnel and/or vehicles from entering the worksite. If working near a road, use a signal person and signs to alert vehicles and pedestrians of potential hazards and falling objects. If needed, use a signal person to direct traffic. The operator should always be alert and follow the signals from the signal person. The operator shall respond to signals only from the appointed signal person, but shall obey a stop signal from anyone at any time. <!-- i…
