    The executive summary will describe the

    major action items associated with the

    analysis.

    It will also have details regarding over-dutied equipment

    and recommendations for protective device settings.

    When energized work is necessary, there

    should be a specific safe work procedure.*

    Energized work should be the last choice when it is not

    feasible to de-energize the work location due to equipment

    design or operation limitations.

    *In accordance with OSHA CFR 1910 Subpart R or Subpart S and NFPA-70E-2015.

    Follow the OSHA regulations for employer

    responsibility.

    Determine who is qualified to work on energized electrical

    equipment and outline the qualifications.

    The analysis report may identify locations

    with high arc flash incident energy levels.

    If it is not feasible to mitigate arc flash hazard at all

    equipment, prioritize by reviewing operational goals and

    identifying locations where interactions with the equipment

    are frequent and prolonged.

    Work with your power system engineer to

    develop a plan to mitigate the hazards

    identified in "Step 4."

    Implement recommendations for over-dutied equipment and

    protective device settings that may have been identified.

    Invest in training for electricians,

    maintenance personnel, site safety teams,

    and facilities management teams.

    Ask:

    Who is qualified to work on electrical equipment?

    Is my day-to-day operation going to be affected by our

    renewed focus on electrical safety?

    What do I need to do to ensure my team is working

    safely?

    Per NPFA-70E, electrical equipment likely to

    require examination, adjustment, servicing

    or maintenance while energized must be

    field-marked with a label containing:

    1. The nominal system voltage

    2. The calculated arc flash boundary

    3. The available incident energy and working distance as

    calculated by the arc-flash-incident energy analysis

    In development of the electrical safety

    policy, a PPE system needs to be

    implemented based on the incident energies

    calculated.

    In the 2015 edition of NFPA-70E, there are no standard

    PPE categories based on calculated incident energy.

    *Table H.3(b) in NFPA-70E offers guidelines for selection of arc-rated clothing and other PPE when incident energy exposure is determined.

    The electrical equipment owner, or

    designated representative, is responsible.

    Improper maintenance can lead to increased operating

    time, which could result in higher arc flash incident energy

    than the values determined by arc flash analysis. If the

    incident energy for an actual arc flash event is higher than

    the incident energy calculated by the arc flash incident

    energy analysis, the electrical worker may not be wearing

    sufficient PPE.

    Continuous improvement focuses on

    removing stagnation and implementing

    evolving processes and procedures.

    Use this opportunity to ensure that equipment continuously

    operates at peak performances, and to ensure safety

    policies and procedures are updated and reviewed on a

    regular basis.
