ARSD 61:15:05:06. Floor covering requirements

Interior floor finish materials in a day care center must be a Class 2 material in required exits, exit passageways, or corridors providing exit access. A Class 2 material is any material having a minimum critical radiant flux of 0.22 watts per square centimeter as established by the procedures specified in NFPA-253, "Standard Method of Test for Critical Radiant Flux of Floor Covering Systems Using a Radiant Heat Energy Source," 2015. If an automatic sprinkler system is installed, floor covering materials need not be classified. Floor covering requirements apply to new construction and to replacing of floor covering in existing facilities.
