(d) NFPA 255-1972, Method of Test of Surface Burning Characteristics of Buildings Materials;
(11) “inspector”: inspectors appointed in accordance with the Public Buildings Safety Act (chapter S-3);
(12) “exit”: a means of egress or a part of a means of egress leading directly from a floor area to another floor area, to a public thoroughfare or an approved open space;
