NFPA 70B & 70E Changes and Additions Webinar Presented By Fluke

Join us for this webinar about NFPA 70B & 70E changes and additions. NFPA 70B and NFPA 70E are both essential standards from the National Fire Protection Association (NFPA) that focus on electrical safety in the workplace. Both standards are critical for protecting workers, reducing the risk of electrical accidents, and ensuring compliance with safety regulations in industrial and commercial environments. Fluke Sales Applications Manager Curt Geeting is presenting on this engaging topic: Curt has worked for Fluke for 24 years. He currently is the Senior Sales Engineer in the NYC & Philadelphia Metro Markets. In total, Curt has worked 40 years in the industry consisting of 14 years in Test Equipment Distribution, 4+ years in Mfg. Representation, NAED Accreditation, Level 1 Thermographer, Level 1 Vibration Specialist, and Power Quality SME.

Agenda Introduction – What is NFPA 70B & 70E 70E Changes and Additions 70B Changes and Additions Arc Flash, Electrical Fires & Safety, oh my!
What is NFPA 70B & 70E • The NFPA, or National Fire Protection Association, is a nonprofit organization dedicated to promoting fire prevention and safety. It develops and publishes codes and standards related to fire protection and electrical safety. • Codes and regulations enforced by Fire Departments, State Fire Marshals, Building Departments, Electrical Inspectors, OSHA and the EPA NFPA 70B is the Standard for Electrical Equipment Maintenance (Updated for 2023) NFPA 70E is the Standard for Electrical Safety in the Workplace (Updated for 2024) https://www.nfpa.org/en
What’s New for 70E and 70B NFPA 70E • Article 100 Definition additions • General Safety, Batteries and Battery Systems, and Capacitance • New Reference Annex S • Safety/Maintenance Relationship • Clarification to Electric Shock Boundaries and Thermography Standards NFPA 70B • “Recommended” vs “Standard” • Electrical Equipment to be Inspected and Maintained • Maintenance Intervals • Environmental Conditions • Condition of Maintenance https://www.nfpa.org/en
New Definitions - General Safety https://www.nfpa.org/en Boundary, Hearing Protection Worker distance at which a 1 percent probability of ear damage exists from a 20 kPa (3.0 psi) shock wave. Boundary, Lung Protection Worker distance at which a 1 percent probability of lung damage exists from a 70 kPa (10 psi) shock wave. Hazard, Arc Blast A source of possible injury or damage to health from the energy deposited into acoustical shock wave and high-velocity shrapnel. Competent Person One who has received safety training and has demonstrated skills to identify and avoid the hazards involved Protector A glove or mitten designed to be worn over rubber insulating gloves. NEW DEFINITIONS - Highlighting the Pressure Wave of an Arc Blast Incident. No longer just Electric Shock and Arc Flash Hazards.
New Definitions – Battery, Battery Systems, and Capacitance Why Should We Care? NFPA sees the growing use of Batteries and Battery Systems: • Proliferating throughout industrial applications • Especially important for renewable energy applications (Solar, Wind) • Defining terms around the safe handling of de-energized energy storage systems Battery Effect: When conductive materials become electrically charged, potentially causing electrical shock or fire Regulated Cell: A battery cell that is subject to regulations regarding its use, handling, and disposal Dielectric Absorption: The property of certain capacitors to recharge after being discharged Discharge Time: The time required to discharge a capacitor to below electrical hazard thresholds Charge Transfer: Improper discharging of capacitor networks that results in transferring charge from one capacitor to another capacitor instead of fully discharging the stored energy https://www.nfpa.org/en Pilot Cell: A test cell that is used to measure the electrolyte's performance characteristics in a battery
• Discusses the term “Condition of Maintenance” • Is electrical equipment well maintained or poorly maintained? • In short – Effective Maintenance of Electrical Equipment Improves Safety. NFPA 70E Annex S – New for 2024 “Electrical safety programs contain requirements to consider the condition of maintenance of electrical equipment and systems. The objective of these requirements is to emphasize the inherent risk to workers associated with performing tasks on electrical equipment that is not properly rated, not properly installed, has not been properly maintained, or otherwise exhibits evidence of an increased risk level for electrical workers or operators.” – NFPA 70E Annex S Introduction “Informative Annex S provides guidance to assist qualified workers to identify sources of information that are useful when assessing the condition of maintenance of electrical equipment.” See NFPA 70B, Standard for Electrical Equipment Maintenance, for additional information. https://www.nfpa.org/en
Discusses methods for determining condition of maintenance: NFPA 70E Annex S – New for 2024, Continued https://www.nfpa.org/en Visual Inspection Maintenance History of Electrical Equipment:  Should be kept and readily accessible.  Labels  Digital & Electronic Methods (CMMS Software) Infrared Thermography Electrical Measurements: • Voltage & Current • Insulation Resistance Tests • Battery Impedance Testing Condition Monitoring Other Possible Methods: Ultrasound for Partial Discharge and Corona
Changes to Electric Shock Boundary and Thermography 70E 2024 clarifies standard for the Electric Shock Boundary when performing Thermographic inspections. Only Qualified Thermographers can perform inspection within Arc Flash and Limited Approach Boundaries as long as • They are wearing proper PPE • Cover is removed and replaced by a Qualified Electrician https://www.nfpa.org/en MAY NOT penetrate Restrictive Approach Electric Shock Boundary while performing Thermography.
Starting in 2023 NFPA 70B – Standard for Electrical Equipment Maintenance Previous Years Electrical Maintenance Programs (EMP) are a “recommended” practice. Electrical Maintenance Programs (EMP) are a “standard” practice.
NFPA 70B – Standards for Electrical Equipment Maintenance 7.4 Infrared Thermography • 7.4.1 Infrared thermography shall be used when required to verify temperature differences (ΔT) of the following: • (1) Similar electrical components under similar loading • (2) Comparison between electrical components and ambient air temperatures • 7.4.2 All accessible and necessary covers shall be removed prior to infrared thermography inspection to provide a clear line of sight to the equipment being scanned. • 7.4.3 Temperature differences between the area of concern and the reference area shall be documented. • 7.4.4 Infrared thermography inspections shall be performed at normal circuit loading. • 7.4.5 Where normal circuit loading is not feasible, circuit loading of not less than 40 percent of nominal circuit loading shall be permitted. • 7.4.6 Circuit loading characteristics shall be documented and retained for future reference. Standards are no longer a suggestion. NFPA 70B 3.2.5: Shall. - Indicates a mandatory requirement. 70B defines fundamental testing methods and all the equipment that shall be tested and at what intervals, depending on capacity, environment and condition. The very first Fundamental Testing Method (NFPA 70B 7.2.1.1) is Infrared Thermographic Inspection of Electrical Connections. “Infrared thermographic inspection of electrical connections and terminations shall be performed in accordance with Section 7.4.” https://www.nfpa.org/en
NFPA 70B – Scope of Work Prescribed scope of work maintenance intervals vary depending on the following factors: Electrical Equipment Scope of Maintenance Condition of Maintenance on Equipment Environmental Factors Use of Equipment outside of Designed Rating Level of Danger with Equipment Failure Prescribed areas for inspection and maintenance Lubrication Maintenance and Tes Visual Inspection Electrical Testing Cleaning Corona Detection Mechanical Inspection Servicing Mechanical Servicing Special Procedures Mechanical Checks
NFPA 70B – Maintenance Intervals Equipment condition assessment (ECA) depends on the following conditions: 1. Equipment physical condition 2. Criticality 3. Operating environment Equipment Condition Assessment Product Scope of Work Condition 1 Condition 2 Condition 3 All Equipment Infrared thermography 12 months 12 months 6 months Scope of Work Example Thermal Detection Equipment Condition Assessment Product Scope of Work Condition 1 Condition 2 Condition 3 Substations Corona Detection 12 months 12 months 6 months High-Voltage Substations Corona Detection 12 months 6 months 4 months Substation Scope of Work Example Corona Detection NFPA 70B now provides mandatory scopes of work and maintenance intervals broken out by product type and based on an equipment condition assessment.
