The OSHA 10-hour General Industry course is for entry-level workers, while the OSHA 30-hour General Industry course is designed for supervisors or workers with safety responsibility. The 10-hour course provides a general overview of common safety and health hazards, while the 30-hour course covers a broader range of topics and in-depth, industry-specific training. Both courses are delivered by OSHA-authorized trainers and lead to the issuance of an official Department of Labor OSHA card.
