The Occupational Safety and Health Administration (OSHA) 30 Construction Outreach Training is a comprehensive program intended for safety directors, field supervisors, and forepersons in the construction industry. The 30-hour course covers a range of topics designed to teach supervisors the rules and regulations for everyone working under their supervision.

The training consists of modules, and at the end of each module, there is a 10-question quiz. To move forward to the next module, you must score at least 70% on each quiz, and you have three attempts to pass each one. If you fail to pass the quiz on your third attempt, you will be locked out of the course and cannot continue with online training. After completing the modules, you must pass a final exam, which is 20 questions long, to receive full credit for the course. You get three opportunities to pass the final exam, and you need a score of at least 70% to pass it.

You have six months from the course enrollment date to complete the 30-hour Construction Outreach Training. If you do not complete the course within six months, your account will expire, and you will need to purchase the course again. However, upon successfully completing the course, you can immediately obtain a temporary printable certificate, and you will receive a DOL Construction Outreach course completion wallet card within two weeks.

OSHA 30 Construction suits workers and supervisors with job site safety responsibilities. The program emphasizes hazard control, avoidance, prevention, and identification for OSHA standards. Therefore, it is best suited for positions such as safety directors, field supervisors, and forepersons who have supervisory duties.

Although DOL cards do not expire at the federal level, some states and industries have unique requirements. Hence, you should renew your training every 3-4 years to stay updated on OSHA regulation changes.
