Electrical Safety Practice Test

Twenty-five questions on jobsite and plant electrical safety, with every answer traced to the paragraph it comes from: ground-fault protection and the assured equipment grounding conductor program, flexible cords and temporary wiring, working near overhead and buried lines, what separates a qualified person from an unqualified one, and the narrow case in which OSHA allows work on parts that are still energized. Construction rules come from 29 CFR 1926 Subpart K and general industry rules from 29 CFR 1910 Subpart S; where the two differ, the question says which one it is asking about. Your employer's training program remains required; this test only helps you review.

Not OSHA-authorized training. SteelToeTools is not affiliated with, endorsed by, or authorized by OSHA or the U.S. Department of Labor. This free educational content does not satisfy any OSHA or other regulatory training requirement, and no card, certificate, or credential is issued. Only OSHA-authorized trainers can deliver OSHA Outreach Training (10-Hour and 30-Hour) and issue DOL cards. Always follow your employer's training program and applicable federal, state, and local requirements.

Frequently asked questions

There is no official OSHA test. OSHA sets what training must cover in 29 CFR 1910.332 and leaves the delivery and the record to the employer; it does not publish or grade an exam. This free practice test is not affiliated with OSHA or the Department of Labor, and nothing is issued for taking it.

No. No card, certificate, or credential is issued. Electrical work assignments come from your employer after training that matches the risk of your job under 1910.332(c), and your employer keeps the record.

No, and nothing online can. 1910.399 defines a qualified person as 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. Demonstrating those skills happens on the equipment, in front of someone who can judge it.

Both. Construction questions come from 29 CFR 1926 Subpart K and general industry questions from 29 CFR 1910 Subpart S. The two are close but not identical — the daily cord inspection, for example, is a construction requirement tied to the assured grounding program, while general industry inspects before use on any shift.

Every explanation names it — 1926.404(b)(1)(iii)(E) for the three-month test interval, 1910.333(a)(1) for the deenergized-first rule, 1926.405(a)(2)(ii)(G) for portable lighting in tanks and vessels. Read the explanations on the questions you got right as well; that is where the value is.

Because OSHA does not publish those numbers for general industry or construction outside 1910.269 and 1926 Subpart V. Arc flash boundaries and clothing categories come from NFPA 70E, a private consensus standard, and reproducing its tables would be a copyright problem and a safety one — your employer's assessment is what governs your job.
