29 CFR 801.1 - Purpose and scope.
(a) Effective December 27, 1988, the Employee Polygraph Protection Act of 1988 (EPPA or the Act) prohibits most private employers (Federal, State, and local government employers are exempted from the Act) from using any lie detector tests either for pre-employment screening or during the course of employment. Polygraph tests, but no other types of lie detector tests, are permitted under limited circumstances subject to certain restrictions. The purpose of this part is to set forth the regulations to carry out the provisions of EPPA.
(b) The regulations in this part are divided into six subparts. Subpart A contains the provisions generally applicable to covered employers, including the requirements relating to the prohibitions on lie detector use and the posting of notices. Subpart A also sets forth interpretations regarding the effect of section 10 of the Act on other laws or collective bargaining agreements. Subpart B sets forth rules regarding the statutory exemptions from application of the Act. Subpart C sets forth the restrictions on polygraph usage under such exemptions. Subpart D sets forth the recordkeeping requirements and the rules on the disclosure of polygraph test information. Subpart E deals with the authority of the Secretary of Labor and the enforcement provisions under the Act. Subpart F contains the procedures and rules of practice necessary for the administrative enforcement of the Act.
