S.C. Code Ann. § 42-11-80: Wilful misrepresentation by employee as to absence of disease; waivers.

If an employee, at the time of his employment, wilfully and falsely represents in writing that he has not previously suffered from the disease which is the cause of disability or death, no compensation shall be payable. If an employee who has previously suffered from an occupational disease desires to continue in an employment to which such a disease is a hazard, he may waive his right to receive further benefits for disablement or disability from such disease by written agreement approved by the commission in accordance with such rules as it may promulgate.
