No qualified employee shall be permitted to approach or take any conductive object closer to exposed energized lines or parts than the distances listed in the following references:

1) The employee is insulated from the energized line or part. Electrical protective equipment, rated for the voltage involved, and properly used, such as fiberglass live line tools, insulated tools, gloves, or sleeves, shall be considered effective insulation for the employee, or

2) The energized line or part is insulated from the employee and from other lines or parts at a different potential. Electrical protective equipment, rated for the voltage involved, and properly used, such as hose, hoods, blankets, mats, or covers, shall be considered effective insulation for the employee, or

3) For live-line bare-hand work, the employee is isolated, insulated, or guarded from any exposed conductive objects.

No unqualified employee shall be permitted to approach or take any conductive object closer to exposed, energized lines or parts than the distance listed in 29CFR 1910.333(c)(3)(i) and NFPA 70E Table 2-3.3.5, Columns 3 and 4

For further information, see the associated text to the tables above.

2.13.4.2 TWO WORKERS

Because of exposure to energized parts, electrical work, independent of voltage, that presents a significant shock or arc blast hazard to employees, needs to be evaluted as to the number of employees involved. (See 2.1.2, 2.1.3, and 29 CFR 1910.269.)

2.13.4.3 ELECTRICAL SAFETY RULES

Before performing any electrical work, each individual shall be familiar with the electrical safety rules. The rules should be regularly reviewed by each employee and at periodic safety meetings to ensure that each individual understands the rules. Employees shall adhere to all safety rules at all times.

Prior to beginning any work at the job site, an individual should be designated as the person in charge (PIC) to be responsible for seeing that the safety rules are followed and to coordinate all the work activities. All personnel assigned to the job shall comply with the safety rules.

The following are safety directions and measures that should be followed when working on energized circuits:

1. Know before work begins the work content and the sequence in which it should be accomplished.

2. Know the safety procedures that shall be followed while performing the work.

3. Ensure that the tools and instruments are in good working order and have up-to-date calibration or testing as required.

4. Know what tools are required and how to use them and what protective equipment is required to perform the job safely.

5. Allow only qualified individuals to operate tools and equipment.

6. Use safety signs, symbols, or accident prevention tags to warn and protect employees where electrical hazards are likely to endanger lives.

7. Use barricades in conjunction with safety signs where it is necessary to prevent or limit employee access to work areas where they might be exposed to uninsulated energized conductors or circuit parts. Do not use metal barricades where they are likely to cause an electrical contact hazard.

8. Use manual signaling and alerting when signs and barricades do not provide sufficient warning and protection from electrical hazards.

9. Limit access to the work area to authorized individuals who are familiar with the work.

10. Ensure that the PIC notifies all individuals involved in the work of any changes in the work conditions.

11. If unsafe conditions develop during the work process, immediately report them to the person in charge or the immediate supervisor.

12. Establish emergency safety procedures to deal with electrical accidents.
