Qualified Person Requirements
• Misconception throughout industry
– What constitutes a Qualified Person:
• Licensed Journeyman Electrician?
• Licensed Master Electrician?
– Typical license requirements:
• Required number of years under a licensed electrician
• Pass a National Electrical Code (NEC) exam
– Experience may be residential
– Not qualified for petrochemical facility
Qualified Person Requirements
• Qualified employees requirements must be
established, before conducting:
– Needs Assessment
– 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 safetyrelated 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
• 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
Electrical Hazard Analysis
• Analysis identifies the hazards of electricity:
– Electric shock
– Electric arc flash
– Electric arc blast
Electrical Hazard Analysis
• Hazard assessment from OSHA 1910.132(d)
– “The employer shall assess the workplace to
determine if hazards are present, or are likely to
be present, which necessitate the use of personal
protective equipment (PPE).”
• NFPA 70E, 110.3(B)(1) provides requirements:
– Shock Hazard Analysis
– Arc Flash Hazard Analysis
Electrical Hazard Analysis
• OSHA 1910.132(d)(2) requires:
– Employer to certify assessment was performed
– Date of the hazard assessment
– Workplace that was evaluated (area or location)
• OSHA may require disclosure of documentation
• Assessment identifies requirements for the
Energized Electrical Work Permit

Typical Insulated Hand Tools
Personal Protective Equipment
• Common misconception
– 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.”
Electrical Safety Program
• OSHA 1910.333(a) states:
– Safety-related work practices shall be employed:
• To prevent electric shock or other injuries
– From either direct or indirect electrical contacts
– When work is performed near or on equipment or circuits
which are or may be energized
– The safety-related work practices shall be consistent with the
nature and extent of the associated electrical hazards
Electrical Safety Program
• OSHA 1910.333(a) also states:
– If exposed live parts are not deenergized:
• Safety-related work practices shall be used
• Work practices shall protect workers
• Work practices shall be suitable for the conditions and
voltage
– If deenergized but not locked or tagged:
• Must treat as energized
Electrical Safety Program
• OSHA 1910.333(c) applies to energized work
– Where employees are exposed to electrical hazards
– Only Qualified Persons may work on energized
– Persons shall be capable of working safely
• OSHA Instruction STD 1-16.7
– Requires a “written procedures and strictly
enforced”
Electrical Safety Program
• NFPA 70E, 110.3 outlines the requirements:
– Awareness and Self-Discipline
– Electrical Safety Program Principles
– Electrical Safety Program Controls

Conclusion
• Extensive training is required for employees
considered to be Qualified Persons
• Training determined by:
– Needs Assessment
– Job/Task Analysis
– Hazard Analysis
Conclusion
• OSHA and NFPA 70E require employers to:
– Document employees have demonstrated
proficiency
– Certify employees are qualified
– Maintain certification for duration of employee’s
employment
• Utilizing only Qualified Persons to perform
electrical work can greatly reduce the risk to the
employee, as well as increasing reliability of the
electrical system and equipment.
