unless:

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

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.
