Course and source checkpoint
Which OSHA Outreach course does your work require?
Confirm the requirement with your employer, project, union, state, or locality before enrolling. This saved choice is separate from all lesson, flashcard, Test, Pathway, score, weak-area, missed-question, readiness, and exam-date progress.
Zero-admission boundary
Course-aligned admissions: 0 / 826. All 798 distinct prompts, 5 lessons, and 23 cards remain mixed supplemental hazard review until every asset has complete course-family, procedure, topic, source, explanation, ownership, security, and human-review records.
Official-source boundary
Practice is not the 30-hour Outreach course
OSHA describes Outreach as voluntary hazard-awareness training, not a certification or license. OSHA does not require a standard test, and the 30-hour class does not replace job-specific training required by OSHA standards. Only successful completion through an authorized trainer or accepted online provider can lead to the Department of Labor completion card. VoltExam is independent supplemental practice and cannot provide the required contact hours or issue the card.

Frequently Asked Questions
What is the OSHA 30-hour course?
OSHA describes its 30-hour Outreach class as voluntary hazard-awareness training intended for supervisors or workers with some safety responsibility. It does not satisfy the training requirements in OSHA standards, and OSHA does not consider the course a certification or license.
Does OSHA require an exam for the 30-hour card?
No. OSHA does not require testing in Outreach classes. An authorized trainer may choose to assess learning, but the trainer decides how a student successfully completes the class. VoltExam practice is not that trainer's assessment and does not predict course completion.
How do I receive an OSHA 30 completion card?
Attend and successfully complete the entire class through an OSHA-authorized Outreach trainer or an OSHA-accepted online provider. The authorized trainer or provider issues the Department of Labor completion card. VoltExam cannot deliver the required contact hours or issue the card.
