There have been a few updates to NFPA 70E regarding the selection of Arc Rated PPE.
NFPA 70E 2015 Article 130.6(C)
NFPA 7OE 130.6 (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 the table 130.7 (C)(16) shall not be permitted.
(1) Incident Energy Analysis Method. The incident energy exposure level shall be based on the working distance of the employee’s face and chest areas from a prospective arc source for the specific task to be performed. Arc-rated clothing and other PPE shall be used by the employee based on the incident energy exposure associated with the specific task. Recognizing that incident energy increases as the distance from the arc flash decreases, additional PPE shall used for any parts of the body that are closer than the distance at which the incident energy is determined.
(2) Arc Flash PPE Categories Method. The requirements of 130.7(C)(15) and 130.7(C)(16) shall apply when the arc flash PPE category method is used for the selection of arc flash PPE.
