The 10 hour OSHA Construction Training Class provides training for workers on the recognition, avoidance, abatement, and prevention of safety and health hazards in workplaces in the construction industry. It also provides information regarding workers' rights, employer responsibilities, and how to file a complaint. This course training is required on all construction sites. It is taught by an Occupational Safety and Health Administration (OSHA) authorized instructor. Students receive a card acknowledging they have completed the class. OSHA cards do not expire. However, as per the New York City Department of Buildings, the card must have been issued within the past 5 years in order to work on any site.
