An OSHA 30 Construction course is a 30-hour training program designed for individuals in the construction industry who hold supervisory roles, like safety directors, field supervisors, and forepersons, providing them with in-depth knowledge of OSHA regulations and safety procedures to effectively oversee workers under their supervision on a construction site; it covers a comprehensive range of topics including fall protection, hazard identification, personal protective equipment, and incident reporting, going beyond the basic safety information covered in a standard OSHA 10 course.
