Frequently Asked Questions

Who must take this training?

OSHA 29 CFR 1910.332 Training states:

(a) Scope. The training requirements contained in this section apply to employees who face a risk of electric shock that is not reduced to a safe level by the electrical installation requirements of §1910.303 through 1910.308.

NOTE: Employees in occupations listed in Table S-4 face such a risk and are required to be trained.


Blue collar supervisors, Electrical and electronic engineers, Electrical and electronic equipment assemblers, Electrical and electronic technicians, Electricians, Industrial machine operators, Material handling equipment operators, Mechanics and repairers, Painters, Riggers and roustabouts, Stationary engineers, and Welders.

Other employees who also may reasonably be expected to face a comparable risk of injury due to electric shock or other electrical hazards must also be trained.

How often is retraining or recertification required?

OSHA has not specified any time frame for required retraining or recertification for Electrical Safety Training (general industry). Since there is no OSHA standard dealing with this specific hazard the OSH Act general duty clause, section 5(a)(1), 29 U.S.C. 654(b)(1) defines the standard which provides that:

(a) Each employer –

(1) shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees.

A recognized hazard is a danger recognized by the employer’s industry or industry in general, by the employer, or by common sense. The general duty clause does not apply if there is an OSHA standard dealing with the hazard, unless the employer knows that the standard does not adequately address the hazard.

Therefore it is our recommendation that workers be retrained at least every three years.

What are the governing regulations?

This online electrical safety training course satisfies the training requirements of OSHA 29 CFR § 1910.301 to 1910.399 Electrical Standard.

Navigation Strategies

Beginners: Complete the course in order from beginning to end. Once any topic is completed, you will have full access to it at any time for one year after registration, to use as a resource.

Intermediate/Advanced Users: Use the course as a flexible resource tool to find what you need, whenever you need it. Try the assessment tests first, if you get 80%+ you can move to the next level, if you get less than 80% you should complete the lecture. This gives you a pre and post-assessment score, which can be used to track your skills improvements.
