Okla. Stat. tit. 63, § 63-2352: Labeling

Each light of safety glazing material manufactured, distributed,

imported or sold for use in hazardous locations or installed in such

a location within the State of Oklahoma shall be permanently labeled

by such means as etching, sandblasting or firing ceramic material on

the safety glazing material. The label shall identify the labeler,

whether manufacturer, fabricator or installer, and the nominal

thickness and the type of safety glazing material and the fact that

said material meets the test requirements of ANSI Standard Z-97.1-

1966 and such other further requirements as may be adopted by the

State Health Department. The label must be legible and visible

after installation. Such safety glazing labeling shall not be used

on other than safety glazing materials.
