What are the prerequisites for the OSHA 500 course?

You must have completed OSHA #510 (Occupational Safety and Health Standards for the Construction Industry) no more than seven years before taking OSHA #500, and have five years of construction safety and health experience. A CSP, CIH, or a bachelor's degree or higher in occupational safety and health or industrial hygiene can substitute for two years of the experience requirement. Experience cannot substitute for the #510 training component, and OSHA does not grant waivers.

What score do I need to pass the OSHA 500?

You need a minimum of 40 points (80%) on the written knowledge test administered at the end of the course, plus a passing score on a presentation test in which you teach an assigned OSHA construction outreach topic. 100% attendance across the 4-day course is also required.

What does OSHA 500 authorization let me do?

Graduates become OSHA-authorized construction outreach trainers who can teach 10-hour and 30-hour construction outreach classes and request Department of Labor student course completion cards through their Authorizing Training Organization (the OTI Education Center that ran their course).

How long does OSHA 500 trainer authorization last?

Four years. To stay authorized you must complete the OSHA #502 Update for Construction Industry Outreach Trainers (or retake OSHA #500) every four years. Expired trainers cannot conduct outreach classes or receive student cards, and extensions are not granted except for a 90-day exemption for military members returning from overseas.

Is the 30-hour construction outreach class the same as OSHA 510?

No. The 30-hour outreach class is a hazard-awareness class delivered by outreach trainers, while OSHA #510 is a standards-based course offered only through OTI Education Centers. OSHA explicitly states the 30-hour class is not considered equivalent to #510 for meeting the OSHA 500 prerequisite.

What topics does the OSHA 500 written test cover?

Expect questions on 29 CFR 1926 standards (Subpart M fall protection, L scaffolds, P excavations, K electrical, CC cranes, and health standards like silica), the Focus Four hazards, OSHA Outreach Training Program requirements and procedures (topic hours, reporting, recordkeeping), and adult learning and presentation techniques.

How much does the OSHA 500 course cost?

Tuition varies by OTI Education Center but typically runs about $765 to $900 for the 4-day course. Check the OSHA OTIEC course schedule for centers and dates near you.

OSHA Outreach Training Program Requirements (2024)

The OSHA #500 Trainer Course is for experienced construction safety professionals who want to become OSHA-authorized construction outreach trainers. Prerequisites are firm: OSHA #510 completed no more than seven years earlier plus five years of construction safety and health experience (CSP, CIH, or a safety degree substitutes for two years, and OSHA grants no waivers of the training component). Over four days at an OTI Education Center, candidates study 29 CFR 1926 standards in depth - Subpart M fall protection (6-ft trigger, 1,800-lb arresting force), Subpart L scaffolds (4x capacity, 10-ft fall protection), Subpart P excavations (5-ft protective systems, soil types A/B/C), Subpart K electrical (GFCI/AEGCP), and Subpart CC cranes - alongside Focus Four hazards, Outreach Training Program procedures (topic-hour minimums, 7.5-hour daily cap, 180-day completion window, OTPR reporting), and adult learning techniques. Passing requires 40 points (80%) on the written knowledge test, a passing presentation test, and full attendance. Authorization runs four years, renewable via OSHA #502.
