S.C. Code § 41-29-200
A person must not be excused from attending and testifying or from producing books, papers, correspondence, memoranda, or other records before the department, an appeal tribunal, or their duly authorized representative or in obedience to the subpoena of them in a cause or proceeding before the department or an appeal tribunal on the ground that the testimony or evidence, documentary or otherwise, required of him may tend to incriminate him or subject him to a penalty or forfeiture. An individual must not be prosecuted or subjected to a penalty or forfeiture for or on account of a transaction, matter, or thing concerning which he is compelled, after having claimed his privilege against self incrimination, to testify or produce evidence, documentary or otherwise, except that the individual testifying must not be exempt from prosecution and punishment for perjury committed in testifying.
