Training and Qualifications of Qualified Workers

DOE-HDBK-1092-98

For temporary wiring installations;

a) All 120-V, single-phase, 15- and 20-A receptacle outlets that are or are not a part of the

permanent wiring of the building or structure and that are in use by employees shall have

GFCI protection for personnel [See 29 CFR 1926.404(b) and NEC Section 305-6(a) and (b)]

or an assured equipment grounding program (See Section 8.2).

b) GFCI protection or an assured equipment grounding program (See Section 8.2) for all other

receptacles to protect against electrical shocks and hazards. [See NEC 305-6(a) and (b)].

c) Receptacles on a two-wire, single-phase portable or vehicle-mounted generator rated not

more than 5 kW, where the circuit conductors of the generator are insulated from the

generator frame and all other grounded surfaces, need not be protected with GFCIs. (See

Figure 2-2 and Section 6.4).

Portable GFCIs shall be trip tested according to the manufacturers instructions.

2.8 TRAINING AND QUALIFICATIONS OF QUALIFIED WORKERS

Only qualified workers shall perform work on electrical systems. It is dangerous for unqualified

personnel to attempt to do electrical work. There should be an employee training program

implemented to qualify workers in the safety-related work practices that pertain to their respective

job assignments. (See 29 CFR 1910.269(a)(2), 1910.332, 1926.950(e), NESC Rules 410 and 420,

and NFPA 70E, Part II, Ch. 2-1 and 2-2.)

2.8.1 FORMAL TRAINING AND QUALIFICATIONS

Management should establish formal training and qualifications for qualified workers before they

are permitted to perform electrical work. Refresher training is recommended at intervals not to

exceed three years to provide an update on new regulations and electrical safety criteria.

The training shall be on-the-job and/or classroom type. The degree of training provided shall be

determined by the risk to the employee. This training shall be documented. Employees shall be

trained and familiar with, but not be limited to, the following:

1. Safety-related work practices, including proper selection and use of PPE, that pertain to their

respective job assignments.

2. Skills and techniques necessary to distinguish exposed live parts from other parts of electrical

equipment.

3. Skills and techniques necessary to determine the nominal voltage of exposed live parts,

clearance distances, and the corresponding voltages to which the qualified person will be

exposed.
