S.C. Code Ann. § 58-17-3120

All railroad companies operating passenger trains or coaches by steam, within or through this State, must put cinder deflectors or wire screens that will effectually keep cinders from engines from entering cars upon all windows of passenger coaches, so as to protect passengers when the windows are raised. The deflectors must extend from the bottom of windows the entire length and three inches above the top of the sash and must be six inches wide and permanently fastened to each outside edge of each window. Any railroad company refusing or neglecting to comply with the provisions of this section is subject to a penalty of not less than five hundred dollars nor more than one thousand dollars for each coach not screened as required by this section, to be recovered by the Office of Regulatory Staff at the request of any person aggrieved by such refusal or neglect, for the benefit of the State. The Office of Regulatory Staff must enforce this section.
