Tenn. Code Ann. § 68-120-301: Part definitions.

As used in this part, unless the context otherwise requires:

(1) “Hazardous locations” means those installations, glazed or to be glazed in commercial and public buildings, known as framed or unframed glass entrance doors; and those installations, glazed or to be glazed in residential buildings and other structures used as dwellings, commercial buildings, and public buildings, known as sliding glass doors, storm doors, shower doors, bathtub enclosures, and fixed glazed panels adjacent to entrance and exit doors that, because of their location, present a barrier in the normal path traveled by persons going into or out of these buildings, and because of their size and design may be mistaken as means of ingress or egress; and any other installation, glazed or to be glazed, in which the use of other than safety glazing materials would constitute an unreasonable hazard as the state fire marshal may determine; whether or not the glazing in such doors, panels, enclosures and other installations is transparent; and

(2) “Safety glazing material” means any glazing material, such as tempered glass, laminated glass, wire glass or rigid plastic, that meets the requirements of the minimum statewide building construction safety standards established by the state fire marshal pursuant to § 68-120-101(a), and that are so constructed, treated, or combined with other materials as to minimize the likelihood of cutting and piercing injuries resulting from human contact with the glazing material.
