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)
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
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.
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.
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.”
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
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
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
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
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
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.
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.
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
Article 105.3 Responsibility has been added to for better definition of Employer and Employee responsibilities. 105.3(A)(N) Employer Responsibility: The Employer shall
have the following responsibilities:
1. Establish, document, and implement the safety-related work practices and procedures required by this standard
2. Provide employees with training in the employer’s safety-related work practices and procedures.
105.3(B)(N)Employee Responsibility:
The employee shall comply with the safety-related
work practices and procedures provided by the
employer

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
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
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.
