The OSHA 10 Construction test is a crucial component of the Occupational Safety and Health Administration’s (OSHA) 10-hour Construction Outreach Training program. This course is designed to provide non-supervisory workers in the construction industry with a fundamental understanding of workplace safety. To successfully complete the course and receive the Department of Labor (DOL) wallet card, participants must pass a series of module quizzes and a final exam.

Throughout the course, participants will encounter module quizzes at the end of each module, consisting of 10 questions each. To move forward, a score of at least 70% is required on each quiz. Participants have three attempts to pass each module quiz; failing to do so results in being locked out of the course, rendering online training unattainable for the participant.

Upon completing the modules, a final exam of 20 questions tests the participant’s knowledge of the information covered throughout the course. A passing score of at least 70% is required, and participants are granted three attempts to pass the final exam. Failure to pass after the third try results in being locked out of the course, disallowing online outreach training completion.

Participants have six months from their enrollment date to complete the 10-hour Construction Outreach Training. After this period, the account expires, and participants must repurchase the course. Successful completion of the course allows participants access to a temporary printable certificate and a DOL Construction Outreach course completion wallet card within two weeks. To receive the DOL wallet card, participants must complete a survey at the end of the course.

OSHA 10 Construction courses are tailored to meet the specific safety requirements of the construction industry, as outlined in 29 CFR 1926. It is important to distinguish between OSHA 10 and OSHA 30 courses. OSHA 30 is a more comprehensive 30-hour training program that covers supervisory responsibilities and a broader range of safety awareness topics, suitable for supervisors such as safety directors, foremen, managers, field supervisors, and crew leads.

The OSHA 10 card serves as a foundational orientation to workplace safety for non-supervisory workers. Although it does not replace mandatory OSHA training, many employers require the card as it ensures a consistent level of safety knowledge among employees. Construction has a high incidence of occupational injury, illness, and death, making OSHA 10 training particularly valuable in this field.

In some jurisdictions, an OSHA 10 Construction card is legally required for work in the industry. These requirements may change over time, but as of now, states and regions that mandate the card include Nevada, Philadelphia (PA), Connecticut, Miami-Dade County (FL), Massachusetts, Missouri, New Hampshire, New York City, New York State, Rhode Island, and West Virginia. Employers may also give preference to job candidates with a DOL card, making it a worthwhile investment for construction workers.

While OSHA 10 cards do not expire according to OSHA, some jurisdictions or employers set a refresher period, often ranging between 3-5 years. The DOL card will display an issue date, which can be used to determine the card’s validity for specific needs.
