1 NFPA 70E 2018 TOP CODE CHANGES Minnesota Safety & Health Conference MAY, 2018

2 DEFINITIONS Electrical Safety Program: (N) A documented system consisting of electrical safety principles, policies, procedures, and processes that direct activities appropriate for the risk associated with electrical hazards. Boundary, Arc Flash: When an arc flash hazard exists, an approach limit from an arc source at which incident energy equals 1.2 cal/cm2 (second degree burn - removed)

3 DEFINITIONS Fault Current: (N) The amount of current delivered at a point on the system during a short-circuit condition. Fault Current, Available: (N) The largest amount of current capable of being delivered at a point on the system during a short circuit

4 DEFINITIONS Maintenance, Condition of: (N) The state of the electrical equipment considering the manufacturer s instructions, manufacturer s recommendations, and applicable industry codes, standards, and recommended practices. Working Distances: (N) The distance between a person s face and chest area and a prospective arc source.

5 INCIDENT INVESTIGATIONS Incident Investigations, Article 110.1(J), (N) states: The electrical safety program shall include elements to investigate electrical incidents. Electrical incidents comprise events or occurrences that result in, or could have resulted in, a fatality or injury.

6 Incident Investigations cont d Informational Note: To decrease complacency and improve electrical workplace safety, the technical committee selected the term incident instead of accident. By requiring an incident investigation, not only do electrical events that result in injury require an investigation, but so do close calls or near misses that could have resulted in injury.

7 Job Safety Planning and Briefing (N) 110(I) 110.1(I) Before starting each job that involves exposure to electrical hazards, the employee in charge shall complete a job safety plan and conduct a job briefing with the employees involved

8 JOB PLANNING AND BRIEFING ARTICLE 110.1(I)

9 110.1(I)(1) (N) The job safety plan shall be in accordance with the following: Be completed by a Qualified person Be documented cont d

10 Include the following information: A description of the job and individual tasks Identification of the electrical hazards associated with each task A shock hazard assessment for tasks involving a shock hazard An arc flash risk assessment for tasks involving an arc flash hazard Work procedures involved, special precautions, and energy sources

11 110.1(I)(2)(N) The job briefing shall cover the job safety plan and the information on the energized electrical work permit, if a permit is required 110.1(I)(3) (N) Change in scope. Additional job safety planning and job briefings shall be held if changes occur during the course of the work that might affect the safety of employees

12 LOCKOUT/TAGOUT AUDIT

13 110.1(K)(3)(N) Lockout/Tagout Program and Procedure Audit: The lock program shall be audited by a qualified person not to exceed 1 year. The audit shall cover at least one lockout/tagout in progress. The audit shall be designed to identify and correct deficiencies in the following: 1. The lockout/tagout program and procedures 2. The lock/tagout training 3. Worker execution of the lockout/tagout procedures

14 RISK ASSESSMENT

15 Risk Assessment: The new risk assessment procedure requires you to address human error and its consequence on employees, procedures, the workplace and equipment. Annex Q has been developed was added to assist in adding this procedure to your Safety program. Additionally, The Hierarchy of Risk Control Methods is now in the standards mandatory text.

16 110.1(H)(2)(N) Human Error: The risk assessment procedure shall address the potential of human error and its negative consequences on people, processes, the work environment, and equipment.

17 110.1(H)(3) (N) Hierarchy of Risk Control: The risk assessment procedure shall require that preventive and protective risk control methods be implemented in accordance with the following: a Elimination b Substitution c Engineering controls d Awareness e Administrative controls f PPE

18 RESPONDSIBILITES

19 Article Responsibility has been added to for better definition of Employer and Employee responsibilities (A)(N) Employer Responsibility: The Employer shall have the following responsibilities: 1. Establish, document, and implement the safetyrelated work practices and procedures required by this standard 2. Provide employees with training in the employer s safety-related work practices and procedures.

20 105.3(B)(N)Employee Responsibility: The employee shall comply with the safety-related work practices and procedures provided by the employer

22 TWO TABLES THAT HAVE BEEN CHANGED

23 Table 130.5(C): Estimate of the Likelihood of Occurrence of an Arc Flash Incident for ac and dc Systems This table was 130.7(C)(15)(a) and has been revised and moved. It can be used for both ac and dc for doing your arc flash risk assessment. It also applies to incident energy analysis method and PPE method

24 Table 130.5(G) has been moved from the annex material (formerly H.3.(b)) to mandatory text. It has been revised to provide guidance on how to select gear when using the incident energy analysis method

25 First Aid, Emergency Response, and Resuscitation (Modified) 110.2(C)(2)(d) Training shall occur at a frequency that satisfies the requirements of the certifying body.
