The OSHA 30-hour training is primarily intended for supervisors, managers, and other individuals with safety responsibilities in their workplaces. The program covers a wide range of topics, including hazard recognition, prevention, and control measures for various workplace hazards, such as falls, electrical hazards, and hazardous materials.
