Job/Task Analysis OSHA and NFPA

Establishes training and qualifying requirements

Qualified Person Requirements

NEC definition of Qualified Person

One who has skills and knowledge related to the

construction and operation of the electrical equipment and installations and has received safety training to recognize and avoid the

hazards involved.

Qualified Person Requirements

OSHA definition of Qualified Person:

One who has received training in and has

demonstrated skills and knowledge in the construction and operation of electric equipment

and installations and the hazards involved.”

Qualified Person Requirements

Note 1 to OSHA definition:

“Whether an employee is considered to be a ‘‘qualified person’’ will depend upon various circumstances in the workplace. For example, it is possible and, in fact, likely for an individual to be considered ‘‘qualified’’ with regard to certain equipment in the workplace, but ‘‘unqualified’’ as to other equipment.”

Qualified Person Requirements

Note 2 to OSHA definition:

“An employee who is undergoing on-the-job training and who, in the course of such training, has demonstrated an ability to perform duties safely at his or her level of training and who is under the direct supervision of a qualified person is considered to be a qualified person for the performance of those duties.”

Qualified Person Requirements

OSHA 1910.332 requires:

Qualified Person to be trained in “the safety-

related work practices that are required by 1910.331 through 1910.335 that pertain to their respective job assignments.”

Qualified Person shall, at a minimum, be trained in:

Skills and techniques to distinguish exposed live parts

Skills and techniques to determine nominal voltage

Clearance distances to exposed voltages

Qualified Person Requirements

(1) Riggers and roustabouts.

(1) Stationary engineers.

(1) Welders.

Footnote (1) Workers in these groups do not need to be trained if their work or the work of those they supervise does not bring them or the employees the supervise close enough to exposed parts of electric circuits operating at 50 volts or more to ground for a hazard to exist.

Qualified Person Requirements

Must be trained in the proper use of:

Special precautionary techniques

Insulating and shielding materials

Insulated tools and test equipment

Job planning

Qualified Person Requirements

Additional training or retraining if:

Inspection indicates non-compliance

– –

Classroom with exam On-the-job demonstration

Hands-on training Figure 1

Hands-On Low-Voltage Circuit Breaker Training

Qualified Person Requirements

• • •

Training shall be:

Classroom

On–the–job

Or a combination of the two Retraining is required:

Not to exceed 3 years All training shall be documented

Needs Assessment

• • • •

Must be performed before training can be accomplished Involves relevant company personnel who:

Are aware of job requirements

Are aware of codes, standards, and regulations Provides insight into past and present performance problems Other factors that may affect performance

Job/Task Analysis

• •

Review needs assessment information Develop initial job description:

Job title

Qualification requirements for the job

General description of job requirements

Description of job position within organization

List of tools and equipment used in the job

List of resource documents and references

Inventory of tasks

Job/Task Analysis

Task inventory is most difficult part of the job description

List of tasks that make up the job

Task is defined as a unit of work that is:

Observable

Measurable

Definite beginning and end

Of relatively short duration

Task are made up of elements or steps

Electrical Hazard Analysis

The electrical hazard analysis determines:

Hazard mitigation techniques

Risk management responsibilities

Personal protective equipment (PPE)

Training program development

Requirements for an Electrical Safety Program

Rubber insulating gloves not required when using insulated tools – this is FALSE Rubber insulating gloves are shock protection Insulated tools are used to prevent:

Going phase-to-ground

Going phase-to-phase Rubber insulating gloves and insulated tools must be used together

Personal Protective Equipment

OSHA 1910.335(a)(2)(ii) provides summary:

Protective shields, protective barriers, or

insulating materials shall be used to protect each employee from shock, burns, or other electrically related injuries while that employee is working near exposed energized parts which might be accidentally contacted or where dangerous

electric heating or arcing might occur.
