S.C. Code Ann. § 24-27-500
Application of Religious Freedom Act to prison regulations.
For the purposes of Chapter 32 of Title 1: (A) A state or local correctional facility's regulation must be considered "in furtherance of a compelling state interest" if the facility demonstrates that the religious activity: (1) sought to be engaged by a prisoner is presumptively dangerous to the health or safety of that prisoner; or (2) poses a direct threat to the health, safety, or security of other prisoners, correctional staff, or the public. (B) A state or local correctional facility regulation may not be considered the "least restrictive means" of furthering a compelling state interest if a reasonable accommodation can be made to protect the safety or security of prisoners, correctional staff, or the public.
