OSHA’S mission is not
SEEK AND DESTROY
OSHA’S mission is
IDENTIFY AND FIX
OSHA’S EXPECTATIONS
Never work on live circuits unless it is absolutely necessary.
OSHA has strict guidelines for working live circuits.
Production or inconvenience is not justification for working
energized.
Not having the authority to shut off power, cannot be used
as an excuse for workers.
OSHA’S EXPECTATIONS

3.
4.
5.
Was an arc flash hazard analysis performed?
Were flash protection boundaries established?
Were all other potential electrical hazards
identified?
Was a shock hazard analyses performed?
Were shock hazard boundaries established?
These are all Questions every EHS professional
should have an answer to.
OSHA’S EXPECTATIONS
• This can be a very complex task for most facilities.
• OSHA inspectors are trained to ask if these analyses were
performed
• This is the only way for electrical hazards to be reduced to a
manageable level.
OSHA’S EXPECTATIONS
Go Home the way you came to work today.
Don’t make your family the victim of complacency.
OSHA’S EXPECTATIONS
The employer must show proof of the appropriate training
and certifications for a person to be deemed qualified in
OSHA’s Eyes
• This is achieved by training, even for the experienced
electrician.
OSHA’S INSPECTIONS
Employer May Qualify for a
"Focused Inspection"
Inspector will "focus" on these four hazard areas:
• Falls
• Struck by
• Caught in/between
•
Electrical
OSHA’S INSPECTIONS
Example OSHA Citation
NFPA 70E
Standard for electrical safety in the workplace
• Arc Flash Assessments and reviews every 5 years!
• Only qualified persons working within the limited
approach boundary energized parts!
• Retraining every 3 years!
• Annual audits of performance!
• CPR/AED annually!
• Release of victims training annually!

130.5 Arc Flash Risk Assessment
An arc flash risk assessment shall be
performed and shall:
(1) Determine if an arc flash hazard exists. If an arc
flash hazard exists, the risk assessment
shall determine:
a. Appropriate safety-related work practices
b. The arc flash boundary
c. The PPE to be used within the arc flash boundary

110.1 (G) Risk Assessment Procedure
(1) Identify hazards
(2) Assess risks

110.1 Electrical Safety Program
• (B) Maintenance. The electrical safety program shall include
elements that consider condition of maintenance of
electrical equipment and systems.
What are we going to Cover
– Training Requirements
– Qualified Persons
– Retraining Requirements
Proper Use of Test Instruments
Article 110.4(1) Testing
Only qualified persons
shall perform tasks such as
testing, troubleshooting,
and voltage measuring
within the LAB or
energized electrical
conductors or circuit parts
operating at 50 volts or
more or where an electrical
hazard exists.
There are many effective ways to train
employees.
110.2 Training Requirements.
(C) Emergency Response Training
Employees shall be trained:
(1) Contact Release.
Employees exposed to shock hazards shall
be trained in methods of safe release of
victims from contact with exposed energized
electrical conductors or circuit parts.
Refresher training shall
occur annually.
110.2 Training Requirements.
(C) Emergency Response Training
Employees shall be trained:
(2) First Aid, Emergency Response, and Resuscitation.
(a) Employees responsible for responding to medical
emergencies shall be trained in first aid and emergency
procedures. (Periodically)
(b) Employees responsible for responding to medical
emergencies shall be trained in cardiopulmonary
resuscitation (CPR).
Refresher training shall occur annually.
110.2 Training Requirements.
(C) Emergency Response Training
Employees shall be trained:
(2) First Aid, Emergency Response, and
Resuscitation. (Continued)
(c) Employees responsible for responding to
medical emergencies shall be trained in the use of
an automated external defibrillator (AED) if an
employer’s emergency response plan includes the
use of this device.
Refresher training shall occur annually.
110.2 Training Requirements.
(C) Emergency Response Training
(3) Training Verification.
Employers shall verify at least annually that
employee training
required by this section is current.
(4) Documentation. The employer shall document
that the training required by this section
has occurred.
100 Definitions
Qualified Person.
One who has demonstrated skills and
knowledge related to the construction
and operation of electrical equipment and
installations and has received safety training
to identify and avoid the hazards involved.
OSHA Definitions
Qualified Person.
The latest revision of the OSHA definition for
qualified person (1910.399 8/07) includes the
phrase
“has demonstrated skills.”
To meet this requirement, the person has to
actually demonstrate that he/she can perform
the task.
Summary of Qualified Persons Skills
• Trained
• Taught
• Learned
• Demonstrated ability to Perform task safely
Summary of Qualified Persons Skills
Is permitted to work
• Operating at 50 volts or more
• Within the limited approach boundary of
• Energized conductors and circuit parts (this is what system
and equipment is made of)
110.2 Training Requirements.
(D)(1) (e) Qualified Person.
Employees shall be trained to select an
appropriate test instrument 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
test instrument that might be used.
110.2 Training Requirements.
(D)(1) (f) Qualified Person.
The employer shall determine through regular
supervision or through inspections conducted on at
least an annual basis that each employee is
complying with the safety-related work practices
required by this standard.
110.2 Training Requirements.
(D)(3) Retraining
Retraining in safety-related work practices and
applicable changes in this standard shall be
performed at intervals not to exceed three years.
110.2 Training Requirements.
(E) Training Documentation
The employer shall document that each
employee has received the training required by
110.2(D).
This documentation shall be made when the employee
demonstrates proficiency in the work practices involved
and shall be maintained for the duration of the employee’s
employment.
