What This Certification Is and Why It Matters

The OSHA 10-Hour and 30-Hour Construction cards are credentials issued by the U.S. Department of Labor that demonstrate foundational knowledge of workplace safety and health hazards in construction. The 10-hour card is primarily intended for entry-level workers, while the 30-hour card is designed for workers with some safety responsibility, including supervisors, forepersons, and safety managers. These cards are valued for life and help workers recognize, avoid, and prevent common job site hazards. Many states and publicly funded construction projects mandate these credentials for employment.

Prerequisites and Eligibility Requirements

There are no formal age or prior experience requirements to enroll in OSHA 10 or 30-hour courses. The training is open to construction workers at all levels. However, some states impose additional mandates: Connecticut, New York, and Pennsylvania require workers on publicly funded projects to hold these certifications and recertify every five years. Florida and Massachusetts also mandate the credential for certain publicly funded work.

Step-by-Step Process to Obtain Certification

1. Enroll in an OSHA-Authorized Course
Complete training through an OSHA-Authorized Outreach Training Provider. Courses are available online and in-person, in English and Spanish.

All training must be completed within 180 days of the course start date. In-person 30-hour classes must span a minimum of four calendar days.

3. Pass the Final Exam
Score at least 70% on the course exam. You have three attempts to pass. You receive immediate feedback after incorrect responses.

4. Complete Course Evaluation
Finish the required course evaluation to receive your certificate of completion.

5. Receive Your Card
A certificate of completion is issued immediately upon passing. Your official Department of Labor OSHA card is shipped within two weeks.

Costs

Training fees vary by provider. The OSHA 10-hour course typically costs $59–$70, while the 30-hour course ranges from $150 and up. These are one-time fees; there are no separate exam fees. Some providers offer bulk discounts for groups.

State-by-State Differences

Most states accept the OSHA 10 and 30-hour cards without additional requirements. However, three states impose recertification mandates:

  • Connecticut: Workers on publicly funded projects must recertify every five years.
  • New York: Workers on publicly funded projects must recertify every five years.
  • Pennsylvania: Workers on publicly funded projects must recertify every five years.

Florida and Massachusetts also require the credential for workers on certain publicly funded projects, though specific recertification timelines were not detailed in available sources.

Renewal and Continuing Education Requirements

The OSHA 10 and 30-hour cards are valid for life and do not expire. However, in Connecticut, New York, and Pennsylvania, workers on publicly funded projects must recertify every five years to maintain eligibility for those specific projects. Renewal typically involves retaking the course and exam. OSHA-Authorized Trainers themselves must complete an update course every four years to maintain their authorization status.

Where to Apply or Register

Enroll directly through OSHA-Authorized Outreach Training Providers. The official OSHA Outreach Training Program website lists authorized providers and course options. Popular providers include ClickSafety, CareerSafe, HSI, and OSHA Education Center. All issue official Department of Labor cards upon successful completion.

Typical Timeline

For online courses, you can complete the 10-hour training in as little as one day, though you have up to 180 days to finish. The 30-hour course requires at least 30.25 hours of study, typically completed over one to two weeks for online learners or four calendar days minimum for in-person classes. Your official DOL card arrives within two weeks of completion, allowing you to seek or maintain employment immediately upon receiving your certificate.
