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.


1. Was an arc flash hazard analysis performed?

2. Were flash protection boundaries established?

3. Were all other potential electrical hazards identified?

4. Was a shock hazard analyses performed?

5. Were shock hazard boundaries established?

These are all Questions every EHS professional

should have an answer to.


• 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.


Go Home the way you came to work today. Don’t make your family the victim of complacency.


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

Inspector will "focus" on these four hazard areas:

• Falls

• Struck by

• Caught in/between

• Electrical

Employer May Qualify for a "Focused Inspection"

OSHA’S INSPECTIONS Example OSHA Citation

• 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!

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

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

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.

Proper Use of Test Instruments

There are many effective ways to train

employees.

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.



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.



(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.



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.

100 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.

OSHA Definitions

• 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)

Summary of Qualified Persons Skills

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.


(D)(1) (e) 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.


(D)(1) (f) Qualified Person.

Retraining in safety-related work practices and

applicable changes in this standard shall be

performed at intervals not to exceed three years.


(D)(3) Retraining

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.

The documentation shall contain the content of the training,

each employee’s name, and dates of training.
