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.

Figure 2-2. There are three methods of providing GFCI protection for construction sites.

4. Procedures on how to perform their jobs safely and properly.

5. How to lockout/tagout energized electrical circuits and equipment safely.

29 CFR 1910.269(a) and 1910.332 also require training for persons other than qualified workers, if job assignments bring them close enough to exposed parts of electrical circuits operating at 50 V or more to ground for a hazard to exist. Other types of training recommended for electrical workers include the following:

a. National Electrical Code (NFPA 70)

b. National Electrical Safety Code (ANSI C2)

c. Use of personal protective grounds-29 CFR 1910.269(n), 1926.954(e), NESC Rule 445, and NFPA 70E, Part II, Ch. 2-4.

d. Use of testing and measuring equipment-29 CFR 1910.269(o) and 1910.334(c)

e. Work permit and work authorization procedures

f. Use and care of personal protective equipment-29 CFR 1910.2690) and 1910.335(a)

g. Proper clothing required for arc blast protection-29 CFR 1910.269(1) and NFPA 70E Part II Ch. 2-3.3

h. First aid and CPR-29 CFR1910.269(b) and 70E Part II, Ch. 2-1.3. Refresher training is recommended at intervals not to exceed 3 years (see OSHA Instruction CPL 2-2.53).
