Section 1: Introduction
1.1 Purpose of the Training Session
To raise awareness about Electrical
Safety and Arc Flash Prevention
5 to 10 people injured, 1 to 2 killed each
day in arc flashes
In 2007, OSHA mandated that
companies SHALL protect against arc
flashes
Steps to “Provide a Safe Work
Environment”
Section 1: Introduction
1.2 Electrical Statistics
Electrical Safety Statistics
About 8,000 electrical contact
injuries referred to emergency rooms
annually in the United States.
One person is electrocuted in the
workplace each working day.
Over 2,000 workers are sent to burn
centers each year with electricalrelated burn injuries.
Section 1: Introduction
Section 1: Introduction
1.3 OSHA History
OSHA – Occupational Safety and Health Administration
Mission – “to assure the safety and health of America’s
workers by setting and enforcing standards; providing training,
outreach, and education; establishing partnerships; and
encouraging continual improvement in workplace safety and
health.”
Fact – Since OSHA’s inception in 1971, nonfatal occupational
injury and illness rates have dropped 60 percent, and
occupational fatality rates have fallen to the lowest annual
preliminary total since 1992
Section 1: Introduction
1.4 OSHA vs. NFPA
OSHA is the “WHAT”
NFPA is the “HOW”

OSHA 29 CFR 1910.332
Qualified Person:
“Those who have training in avoiding the electrical hazards of
working on or near exposed energized parts.”
This is a broad description for a qualified person. An
electrical qualified person is more defined in the NFPA 70E

2.7 OSHA 29 CFR 1910.333 (c)(2)
Work on energized equipment:
“Only qualified persons may work on electrical circuit
parts or equipment that have not de-energized under the
procedures of paragraph (b) of this section. Such
persons shall be familiar with the proper use of special
precautionary techniques, personal protective
equipment, insulating and shielding materials, and
insulated tools.”
Section 3: NFPA 70E
3.2 NFPA Regulating Publications
Application of Safety Related Work Practices
Responsibility (NFPA 70E 105.3)
The employer shall provide the safety
related work practices and shall train the
employee, who shall then implement them.
Section 3: NFPA 70E
3.2 NFPA Regulating Publications
NFPA 110.1 (C)
110.1 Relationships with contractors
(outside service personnel, etc)
(A)(2) The host employer shall report
observed contract-employer-related
violations of this standard to the contract
employer.
(B)(2) The contract employer shall
ensure that each of his or her
employees follows the work practices
required by this standard and safetyrelated work rules required by the host
employer.
Section 3: NFPA 70E
3.2 NFPA Regulating Publications

110.2 Training Requirements
(C) Emergency Procedures
Employees exposed to shock hazards and
those employees responsible for taking action
in case of emergency shall be trained in
methods of release of victims from contact with
exposed energized electrical conductors or
circuit parts. Employees shall be regularly
instructed in methods of first aid and emergency
procedures, such as approved methods of

resuscitation, including cardiopulmonary
resuscitation and automatic external defibrillator
(AED) use, shall be certified by the employer
annually.
Section 3: NFPA 70E
3.3 Need to Know
NFPA ARTICLE 130
130.2 Electrically Safe Working
Conditions. Energized electrical
conductors and circuit parts to which an
employee might be exposed shall be put
into an electrically safe work condition
before an employee performs work if either
of the following conditions exist:
The employee is within the limited
approach boundary.
The employee interacts with equipment
where conductors or circuit parts are not
exposed, but an increased risk of injury
from an exposure to an arc flash hazard
exists.
Section 3: NFPA 70E
3.3 Need to Know
130.2 (A) Energized Work
1) Greater Hazard – Energized work shall
be permitted where the employer can
demonstrate that de-energizing
introduces additional hazards or
increased risk.
2) Infeasibility – Energized work shall be
permitted where the employer can
demonstrate that the task to be
performed is infeasible in a de-energized
state
3) Less than 50V – Shall NOT be required
to be de-energized
Section 3: NFPA 70E
3.3 Need to Know
NFPA 130.3
(A)(2) Energized electrical
conductors and circuit partsUnsafe work condition. Only
qualified persons shall be permitted to
work on electrical conductors or circuit
parts that have not been put into an
electrically safe work condition.
Section 3: NFPA 70E
3.3 Need to Know
NFPA 130.4
Approach Boundaries to Energized
Electrical Conductors or Circuit Parts
(A) Shock Hazard Analysis A shock
hazard analysis shall determine the
voltage to which personnel will be
exposed, the boundary requirements,
and the PPE necessary in order to
minimize the possibility of electric
shock to personnel.
Reference Table 130.4(C) (a)(b)
NEW Table on: DC Approach
Boundaries
Section 3: NFPA 70E

NFPA 130.5
Arc Flash Hazard Analysis
Shall determine the arc flash
boundary, the incident energy at the
working distance and PPE within the
arc flash boundary.
Shall be updated when a major
modification or renovations takes
place.
Shall be reviewed periodically, not to
exceed 5 years.
Section 3: NFPA 70E
3.3 Need to Know
NFPA 130.5 (C) Equipment Labeling.
Electrical equipment such as switchboards,
panelboards, industrial control panels, meter
socket enclosures, and motor control centers that
are in other than dwelling units, and are likely to
require examination, adjustment, servicing, or
maintenance while energized, shall be field
marked with a label containing all the following
information:
At least one of the following:
Available incident energy and the
corresponding working distance
Minimum arc rating of clothing
Required level of PPE
Highest Hazard/Risk Category (HRC) for
the equipment
Nominal system voltage
Arc flash boundary
Section 3: NFPA 70E
3.3 Need to Know
NFPA 130.6

How to Get Started
• Get Upper Management Support
Building new Culture Only works Top Down
You will have to purchase Arc Flash Study
You will have to purchase PPE
You will have to increase Training
You don’t have to do it alone
There are many Engineering Firms
There are many Training Organizations
There are few who can do all of it
29
How to Get Started
• Perform an Arc Flash Study
Sole Source to a Trusted Engineer
RFP Process
Provides The Risk assessment DATA
• Use Data to align “Qualified” People
The Energy Levels of your system get aligned
with the resume’s on your team
Deeming one “Qualified” is not easy, and the
employee and employer have to be very clear
on RISK (Top Down again) OPEN
COMMUNICATION!
30
How to Get Started
• Training in 70E
Every Year!, Every 3 Year’s required
NFPA changes every 3…hmm
New Maintenance rules in 2015 Standard!
• Document Arc Flash Program
• It sits right next to your LOTO
• Its custom to your system and your staff
LOTO (Lockout/Tagout) This better be implemented already!
•
work experience/interpersonal skills
It instills a positive culture, allow for healthy
job briefings and will reduce your Electrical
related Risks.
