What is the OSHA 500 course and who can take it?
OSHA 500 is the trainer course in occupational safety and health standards for the construction industry, delivered by OSHA Training Institute Education Centers. Completing it authorises you to conduct OSHA 10-hour and 30-hour construction Outreach Training Program classes and to issue Department of Labor course-completion cards to your students. Entry is gated: you must have completed OSHA 510 (Occupational Safety and Health Standards for the Construction Industry) within the previous seven years, and you must have five years of construction safety experience — a degree in occupational safety and health, a Certified Safety Professional or a Certified Industrial Hygienist designation may substitute for part of that requirement. Trainer authorisation lasts four years and is renewed by completing the OSHA 502 update course before it expires.
- OSHA 500 authorises you to teach OSHA 10 and 30-hour construction Outreach classes and issue DOL student cards.
- Entry requires OSHA 510 within the previous seven years plus five years of construction safety experience.
- Assessment is a written exam on 29 CFR 1926 plus a graded teaching presentation.
- Authorisation lasts four years and is renewed through the OSHA 502 update course.

OSHA 500 Assessment, Exam and Teach-Back
Written exam plus a graded student presentation
The course is assessed on two things: a written examination on the 29 CFR 1926 construction standards and a student teaching presentation in which you deliver a segment of Outreach material to the class and are critiqued on it. Candidates who do not pass both do not receive trainer authorisation, because the whole point of the course is to certify that you can teach the material, not merely that you know it.
What authorisation lets you do
What does trainer authorisation do for a safety career?
Authorisation turns a safety role into a revenue and compliance function: an authorised trainer can deliver Outreach in-house instead of buying seats, and can sell training externally. BLS reports the wage for the occupations these trainers typically sit in rather than for the authorisation itself.
GlobalCybers reimburses certification fees after a successful permanent placement through our network.
What the OSHA 500 Course Covers, Trainer Content
Outreach Program Requirements
The procedures that govern the whole programme: minimum topic hours, mandatory and elective topics, class size and delivery-time limits, and the paperwork that has to follow every class.
1926 Standards in Teaching Depth
Fall protection, electrical, struck-by and caught-in hazards — the Focus Four — taught at the level you need to answer a room full of experienced tradespeople rather than merely recite the rule.
Adult Learning & Presentation
Structuring a session, handling the disengaged or hostile student, using site photographs and incident case studies, and the teach-back that the course grades you on.
Documentation & Card Issuance
Roster requirements, verification of attendance hours, how cards are requested through your Education Center, and the record-retention period.
Trainer Integrity
The conduct rules that keep the programme credible — no shortcutting hours, no issuing cards for classes not delivered — and the revocation process when they are broken.
Keeping Authorisation Current
The four-year cycle and the OSHA 502 update course, including what happens to trainers who let the window close.
How do you become an authorised OSHA construction trainer?
Complete OSHA 510 first
OSHA 510, Occupational Safety and Health Standards for the Construction Industry, is the mandatory prerequisite and must have been completed within the previous seven years. Take it at an OTI Education Center; the 500 will ask for the completion record at registration.
Document five years of construction safety experience
You need five years of construction safety experience to enter the course. A college degree in occupational safety and health, or the Certified Safety Professional or Certified Industrial Hygienist designation, can substitute for part of that requirement — the Education Center verifies eligibility before it will seat you.
Attend the 500 at an OTI Education Center
The trainer course is delivered by the network of OSHA Training Institute Education Centers rather than by OSHA directly. You sit the written examination on the construction standards and deliver a graded teaching presentation to the class.
Renew every four years through OSHA 502
Trainer authorisation runs four years. Complete OSHA 502, the update course for construction Outreach trainers, before it expires. Trainers who let the authorisation lapse beyond the allowed window have to return to the full 500 course rather than the update.
Only Authorised Trainers May Issue DOL Cards
The Outreach Training Program is voluntary for students but tightly controlled for trainers. Department of Labor 10-hour and 30-hour cards may only be issued through an authorised trainer working under an OTI Education Center, and the trainer is personally accountable for the hours actually delivered and the accuracy of the class roster. Cards obtained outside that chain are not valid, which is why employers and jurisdictions that require OSHA 10 or 30 — New York City's Local Law 196 among them — verify the issuing trainer.
