Workshop
Comment 70E-191b, Words & Phrases Task Group
Proposal 70E-1
2008 IEEE, IAS Electrical Safety Workshop
*
Article 100 Definitions
"live parts" was changed to "energized electrical conductors or
circuit parts" throughout the standard.
C 70E-191b WPTG
P 70E-1
Insulated conductor, is it energized, previously the term live
only applied to the conductor, not the insulation
*
NFPA 70E Words & Phrases Task Group
Created between ROP and ROC meetings to deal with terms such as
“exposed”, “energized”, “live parts”, “where equipment is
interacted with”, “working on”, “working near”, etc.
WPTG did a good job with the monumental task of cleaning up
inconsistent language
Members: Louis Barrios (API), Palmer Hickman (IBEW), Daniel
Roberts (CSA Z462), Vince Saporita (NEMA), David Wallis (OSHA), Jim
White (NETA) and Jim Dollard (IBEW).
Paul Debrowsky Presentation, 2008 IEEE IAS Electrical Safety
Workshop
New definition and Fine Print Notes (FPN) to better identify
when a flash hazard exists
2008 IEEE, IAS Electrical Safety Workshop
*
Article 100 Definitions
Arc Flash Hazard. A dangerous condition associated with the
possible release of energy caused by an electric arc.
Paul Debrowsky Presentation, 2008 IEEE IAS Electrical Safety
Workshop
One of the most significant changes in 2009 edition. Provides
the 70E committee’s intent on when an arc flash hazard exists
2008 IEEE, IAS Electrical Safety Workshop
*
Arc Flash Hazard Continued
FPN No. 1: A flash hazard may exist when energized electrical
conductors or circuit parts are exposed or when they are within
equipment in a guarded or enclosed condition, provided a person is
interacting with the equipment in such a manner that could cause an
electric arc. Under normal operating conditions, enclosed energized
equipment that has been properly installed and maintained is not
likely to pose a flash hazard.
Paul Debrowsky Presentation, 2008 IEEE IAS Electrical Safety
Workshop
2008 IEEE, IAS Electrical Safety Workshop
*
Arc Flash Hazard Continued
FPN No. 2: See Table 130.7(C)(9) for examples of activities that
could pose a flash hazard.
FPN No. 3: See 130.3 for flash hazard analysis information.
C 70E-207 WPTG
P 70E-244
Paul Debrowsky Presentation, 2008 IEEE IAS Electrical Safety
Workshop
New definition, establishes the basis for later requirement to
wear “balaclava” with face shields
2008 IEEE, IAS Electrical Safety Workshop
*
Article 100 Definitions
New
Balaclava (Sock Hood). An arc-rated FR hood that protects the
neck and head except for facial area of the eyes and nose.
P 70E-50
Paul Debrowsky Presentation, 2008 IEEE IAS Electrical Safety
Workshop
This change along with the new definition of “arc flash hazard”
clarify when an arc flash boundary exists
2008 IEEE, IAS Electrical Safety Workshop
*
Article 100 Definitions
Boundary, Arc Flash Protection. When an arc flash hazard exists,
an approach limit at a distance from a prospective arc source
within which a person could receive a second degree burn if an
electrical arc flash were to occur.
C 70E-212 WPTG
P 70E-36
Paul Debrowsky Presentation, 2008 IEEE IAS Electrical Safety
Workshop
2009 Recognizes arc-resistant switchgear
2008 IEEE, IAS Electrical Safety Workshop
*
Article 100 Definitions
New
Switchgear, Arc-Resistant
Switchgear, Metal-Clad.
Metal-Enclosed Power Switchgear.
C 70E-230
P 70E-50a
[Metal-Enclosed from 2008 NEC]
*
Paul Debrowsky Presentation, 2008 IEEE IAS Electrical Safety
Workshop
“Working Near” was an ambiguous term used inconsistently in 70E
to represent shock and/or flash hazards. The “limited approach
boundary” only applies to shock. The term “working near” will no
longer appear in NFPA 70E and has been replaced with either the
“Limited Approach Boundary” or “Arc Flash Protection Boundary”
2008 IEEE, IAS Electrical Safety Workshop
*
Article 100 Definitions
Paul Debrowsky Presentation, 2008 IEEE IAS Electrical Safety
Workshop
“Live” was replaced by “energized” and “parts” was replaced by
“electrical conductors and circuit parts” throughout NFPA 70E to be
more consistent with current OSHA language. “Exposed live parts” or
“live parts” no longer appear in NFPA 70E.
2008 IEEE, IAS Electrical Safety Workshop
*
Article 100 Definitions
API proposal to differentiate “diagnostic testing” from “repair”
was accepted
Paul Debrowsky Presentation, 2008 IEEE IAS Electrical Safety
Workshop
Further clarifies that electrical hazards generally exist “while
work is being performed on energized electrical conductors,
electrical equipment, or circuit parts”.
2008 IEEE, IAS Electrical Safety Workshop
*
110.1 Scope.
Chapter one covers electrical safety-related work practices and
procedures for employees who are exposed to an electrical hazard
while work is being performed on energized electrical conductors,
electrical equipment, or circuit parts in workplaces covered in the
scope of this standard. …..
C 70E-258 P 70E-63
Paul Debrowsky Presentation, 2008 IEEE IAS Electrical Safety
Workshop
API attempted to change this to every two years failed.
2008 IEEE, IAS Electrical Safety Workshop

[The OSHA Directive CPL 2-2.53 Guidelines for First Aid Training
Program recommends annual retraining.]
*
Paul Debrowsky Presentation, 2008 IEEE IAS Electrical Safety

voltage-detector and shall demonstrate how to use a device to
verify the absence of voltage, including interpreting indications
provided by the device. The training shall include information that
enables the employee to understand all limitations of each specific
voltage-detector that may be used.
P 70E-74 C 70E-282

Originally proposed - “not to exceed 3 yr intervals”
As modified, language is more consistent with new OSHA
language.
2008 IEEE, IAS Electrical Safety Workshop
*
110.6(D)(3) Retraining. New
An employee shall receive additional training (or retraining)
under any of the following conditions:
(a) If the supervision or annual inspections indicate that the
employee is not complying with the safety-related work
practices
Paul Debrowsky Presentation, 2008 IEEE IAS Electrical Safety
Workshop
2008 IEEE, IAS Electrical Safety Workshop
*
110.6(D)(3) Continued
(b) If new technology, new types of equipment, or changes in
procedures necessitate the use of safety-related work practices
that are different from those which the employee would normally
use, or
(c) If he or she must employ safety related work practices that
are not normally used during his or her regular job duties".

Arc Flash Hazard
Continued
•
FPN No. 1: A flash hazard may exist when
energized electrical conductors or circuit
parts are exposed or when they are within
equipment in a guarded or enclosed
condition, provided a
person is interacting
with the equipment in such a manner that
could cause an electric arc. Under normal
operating conditions, enclosed energized
equipment that has been properly installed
and maintained is not likely to pose a flash
hazard.
