OSHA 30 is a 30-hour training course that prepares workers and supervisors to recognize, avoid, abate, and prevent health and safety hazards in the workplace. The course covers a variety of safety subjects and provides in-depth, industry-specific training. It is intended for workers whose job positions carry health and safety responsibility, such as managers and field supervisors. The course is available in two industry-specific versions: construction and general industry. The OSHA 30-hour training program is not mandatory, but it can be useful in advancing ones career and promoting a safety culture in the workplace. Upon completion of the course, participants receive an official OSHA 30 card from the U.S. Department of Labor.
