    The 2015 Has Arrived!

    The NFPA 70E was first

    published in 1979 at the

    request of OSHA.

    The 2015 Edition is the tenth to

    be published.

    Each edition is made to bring

    clarification and a safer work

    environment.

    The 2015 edition brings in

    some major changes.

    Global Changes

    These Global Changes provide

    accuracy and better harmonize with

    other standards addressing risk

    and hazards

    Definitions

    Qualified Person.One who has demonstrated

    skills and knowledge related to the construc- tion

    and operation of electrical equipment and

    installations and has received safety training toidentify and avoid the hazards involved.

    Risk.A combination of the likelihood of occurrence

    of injury or damage to health and the severity ofinjury or damage to health that results from a

    hazard.

  • 8/10/2019 2-2015 NFPA 70E Changes

    6/31

    Definitions

    Risk Assessment.An overall process that

    identifies hazards, estimates the potential severity

    of injury or damage to health, estimates the

    likelihood of occurrence of injury or damage tohealth, and determines if protective measures are

    required.

    InformationalNote: As used in this standard, arcflash risk assessment and shock risk assessment

    are types of risk assessments.

    Article 110.1(A)Electrical Safety Program.

    General. The employer shall implement and document an overall

    electrical safety program that directs activity appropriate to the risk

    associated with electrical hazards. The electrical safety programshall be implemented as part of the employers overall occupational

    health and safety management system, when one exists.

    Informational Note No. 1:Safety-related work practices such as

    verification of proper maintenance and installation, alerting

    techniques, auditing requirements, and training requirements

    11/31

    Article 130.2(A)(4)This was added in the 2015 Text:

    Article 130.5Arc Flash Risk Assessment: An arc flash risk assessment shall be performed and shall:

    (1) Determine if an arc flash hazard exists. If an arc flash hazard exists, the risk assessment shall

    determine:

    a. Appropriate safety-related work practices

    b. The arc flash boundary

    c. The PPE to be used within the arc flash boundary

    (2) Updated with major modifications and reviewed periodically, at intervals not to exceed 5 yrs.

    (3) Take into consideration the design of the overcorrect protective device and its opening time,

    including its condition of maintenance.

    Informational Note No. 1: Where equipment is not properly installed or maintained, PPE

    selection based upon incident energy analysis or the PPE category method may not provide

    adequate protection from arc flash hazards.

  • 8/10/2019 2-2015 NFPA 70E Changes

    19/31

    Article 130.5(C)Arc Flash PPE: One of the following methods shall be

    used for the selection of PPE. Either, but not both, methods

    shall be permitted to be used on the same piece of

    equipment. The results of an incident energy analysis to

    specify an arc flash PPE Category in Table 130.7(C)(16)

    shall not be permitted.

    Arc-Rated vs. Flame-

    ResistantProtective equipment and clothing that is intended for protectionfrom an arcing fault must be rated by the manufacturer for use in

    an environment influenced by an electrical arc. Although the term

    flame resistant (FR)has been used in previous editions of NFPA

    70E, an FR marking on a garment does not necessarily mean it isarc rated. The term flame resistant is no longer used in NFPA

    70E; this change has been made to clarify that onlyclothing or

    other PPE with an arc ratingis acceptable for protecting persons

    against arc flash hazards. The term flame resistant could indicate

    exposure to other events such as flames from a fire. As anexample, FR clothing for race car drivers or pilots is not suitable

    for arc flash protection.Arc-rated clothing is the only clothing

    marked with the cal/cm2 rating.

    flash PPE is required. When arc flash PPE is required, Table 130.7(C)(15)(A)(b)

    shall be used to determine the arc flash PPE category. The estimated maximum

    available short-circuit current, maxi- mum fault-clearing times, and minimum

    working distances for various ac equipment types or classifications are listed inTable 130.7(C)(15)(A)(b). An incident energy analysis shall be required in
