OSHA 10-hour training is designed for entry-level workers in construction and general industry. While the OSHA Outreach Training Program is voluntary, employers may require you to earn an OSHA 10 card before you start work. This training is also mandatory in certain states, cities and local jurisdictions. OSHA 10-hour construction training is appropriate for workers who perform new construction, alterations or repairs. If you work in any industry other than construction, agriculture or maritime, OSHA considers you a general industry worker and recommends the OSHA 10 General industry course. OSHA 30-Hour training is appropriate for supervisors and workers with some safety responsibilities. How to Earn Your OSHA 10 DOL Card When you successfully complete OSHA 10-hour training, you will receive an official OSHA 10 DOL card in construction or general industry. We’ll deliver your plastic, wallet-sized OSHA 10 card by mail free of charge. Immediately after you finish the course, you can download a certificate of completion. While you wait for your OSHA 10 DOL card to arrive in the mail, you can provide the certificate to your employer to prove you completed your training. What Are the Benefits of an OSHA 10 Card? Acquiring an OSHA 10 DOL card proves to employers that you have completed 10 hours of OSHA-authorized training on critical workplace safety topics. Entry-level workers with this credential have industry-specific knowledge and skills that help prevent injuries and keep workplaces safe and productive.
