S.D. Codified Laws § 34-28-6
Each lite of safety glazing material manufactured, distributed, imported, or sold for use in hazardous locations, or installed in such a location within the State of South Dakota shall be permanently labeled by such means as etching, sandblasting, firing of ceramic material, hot-die stamping, transparent pressure sensitive labels, or by other suitable means. The label shall identify the seller, whether manufacturer, fabricator, or installer, the nominal thickness and the type of safety glazing material, and the fact that said material meets the test requirements of the American National Standards Institute Standard Z-97.1-1972. The label must be legible and visible after installation. Such safety glazing labeling shall not be used on other than safety glazing materials. A violation of this section is a petty offense.
