What annex in NFPA 70E addresses the general categories of electrical hazards?
Annex K
Annex K, General Categories of Electrical Hazards: This annex was greatly expanded, and many new statistics were added.
What does the NFPA 70E standard now consider?
NFPA 70E establishes safety processes that use policies, procedures, and program controls to reduce the risk associated with the use of electricity to an acceptable level. The core objective is practical, accomplishable electrical safety that results in the employee going home safe at the end of the day.
What two things determine according to the NFPA 70E the type of PPE required?
To determine the right PPE, you must pick one of two methods, according to Grainger: an incident energy analysis method or an arc flash PPE category method. You can’t use both. The incident energy analysis method calculates “the incident energy and flash boundary” based on tables within the NFPA 70E guidelines.
What are the 3 chapters of NFPA 70E?
Listed below are major requirements of NFPA 70E that should be included in this procedure.
- Chapter 1: Safety-Related Work Practices.
- Article 110: General Requirements for Electrical Safety-Related Work Practices.
- Article 120: Establishing an Electrically Safe Work Condition.
- Article 130: Working on or Near Live Parts.
What does chapter 3 of the NFPA 70E cover?
Chapter 3 is titled “Safety Requirements for Special Equipment” and includes equipment such as: Electrolytic Cells, Batteries and Battery Rooms, Lasers, Power Electronic Equipment, R&D Labs and Capacitors.
What is the primary focus of the NFPA 70E?
Originally developed at OSHA’s request, NFPA 70E helps companies and employees avoid workplace injuries and fatalities due to shock, electrocution, arc flash, and arc blast, and assists in complying with OSHA 1910 Subpart S and OSHA 1926 Subpart K.
What are the two main types of risk assessments conducted under NFPA 70E?
The severity of an injury also depends on multiple factors and conditions, which is why it’s critical to follow proper procedures and conduct an assessment in the first place. The NFPA 70E requires a risk assessment for two types of hazards: shock and arc flash.
What is Annex N?
Annex N, Example Industrial Procedures and Policies for Working Near Overhead Electrical Lines and Equipment: Contact with energized overhead lines is frequently fatal. This annex provides an example of an industrial procedure for working near overhead electrical systems.
What is mainly covered in Chapter 2 of the NFPA 70E standard?
(1) Chapter 2 covers practical safety-related maintenance requirements for electrical equipment and installations in workplaces as included in 90.2. These requirements identify only that maintenance directly associated with employee safety.
What changes to NFPA 70E were recently adopted?
In the 2018 70E the table was modified to eliminate any clothing or PPE under 1.2 cal/cm2, because it only deals with arc-rated clothing and other PPE. The table was renamed Table 130.5(G) and put into the body of the standard. Its use is “permitted”, meaning it’s an option—it can be used, but is not mandatory.
What is the first priority of NFPA 70E?
the elimination of the hazard
New NFPA 70E explicitly states that the first priority must be the elimination of the hazard. The Standard continues to evolve to address risk assessment and introduces human factors, such as human error, as part of that assessment.
What the NFPA 70E does not cover?
Not covered are – electrical installations in marine, aircraft, auto vehicles, communications and electrical utilities. Key principles covered are JSA/JHA/AHA procedures to ascertain shock protection boundaries, arc flash incident energy expressed in calories/cm2, lockout-tagout, and personal protective equipment.
What is PPE Matrix?

Is fall protection covered by NFPA 70E?
NFPA 70E Covers Electrical Hazards Only. The NFPA 70E standard doesn’t cover other construction hazards such as fall protection, safe use of ladders and scaffolds, hazardous substances, and respirators. These other subjects are covered by OSHA construction safety regulations.
