Electrical Safety PPE Requirements

The Employees' Obligation

 

Employees must follow the requirements of the Arc Flash Hazard label by wearing the proper personal protective equipment (PPE), use insulated tools and obey other safety related precautions. This includes not working on or near the circuit unless you are a “qualified” worker.

Qualified person: One who has received training in and has demonstrated skills and knowledge in the construction and operation of electric equipment and installations and the hazards involved.

Additional requirements for qualified persons. Qualified persons (i.e. those permitted to work on or near exposed energized parts) shall, at a minimum, be trained in and familiar with the following:

  • The skills and techniques necessary to distinguish exposed live parts from other parts of electric equipment.
  • The skills and techniques necessary to determine the nominal voltage of exposed live parts, and
  • The clearance distances specified in 1910.333(c) and the corresponding voltages to which the qualified person will be exposed.

AN: As needed [in addition to the protective clothing and PPE required by 130.5(C)(1)].

SR:  Selection of one in group is required by 130.5(C)(1).

Notes:

(1)     Face shields with a wrap-around guarding to protect the face, chin, forehead, ears and neck area are required by 130.7(C)(10)(c).  For full head and neck protection, use a balaclava or an arc flash hood.

(2)    All items not designated “AN” are required by 130.7(C)

(3)    Arc ratings can be for a single layer, such as an arc-rated shirt and pants or coverall, or for an arc flash suit or a multi-layer system consisting of a combination of arc-rated shirt and pants, coverall and arc flash suit.

(4)    Rubber insulating gloves with leather protectors provide arc flash protection in addition to shock protection.  Higher class rubber insulating gloves with leather protectors, due to their increased material thickness, provide increased arc flash protection.
