Labels must include nominal system voltage arc flash boundary at least one of the following: 1) the available incident energy and corresponding working distance, or 2) the arc flash PPE category for the equipment as listed in tables in the standard, but not both minimum arc rating of clothing and site-specific level of PPE. Labels: NFPA 70E requires equipment owners to apply detailed and informative labels to any electrical equipment that is likely to require adjustment or maintenance while energized. Because different equipment may pose different hazards, and different tasks may require different skills, it's possible for a given worker to be "qualified" for one job and "unqualified" for another. An unqualified person does not have these skills, knowledge, or training. Qualified Person: NFPA 70E defines a qualified person as someone who has the skills and knowledge to work on electrical equipment, and who has received the training to identify and avoid the associated hazards. One or the other method must be used, but not both on the same piece of electrical equipment. If likelihood does exist (designated as a yes response in the table) appropriate arc flash PPE must be determined by one of two methods: Incident energy analysis method or Arc flash PPE category method. They must identify the hazard, estimate the likelihood of occurrence of injury or damage to health and the potential severity of injury or damage to health and determine if additional protective measures are required, including the use of PPE. To quantify the risk present in the covered work, NFPA 70E-2018 identifies two assessments that must be done for each affected electrical equipment piece: Shock Risk Assessment and Arc Flash Risk Assessment. NFPA 70E also specifies safe work practices for employees who may not be directly working on electrical equipment, but who are performing work that might expose them to electrical hazards.Īrticle 110 also addresses the potential for human error and its negative consequences on people, processes, the work environment and equipment and Job Safety Planning and Job Briefing.Īrticle 120 requires employers to establish, document, and implement a lockout/tagout program and specify lockout/tagout procedures to safeguard workers from exposure to electrical hazards.Īrticle 130 of the standard specifically addresses work involving electrical hazards and covers any work condition that requires an electrically safe work condition and any work involving safety-related work practices, assessments, precautions, and procedures when an electrically safe work condition cannot be established. Purchase NFPA 70E® at NFPA 70E defines work practices that protect workers from electrical hazards, including arc flash hazards, during the inspection, operation, and maintenance of electrical equipment. Key requirementsįar too many to list in detail here. The electrical safety program must include elements to investigate electrical incidents.
