Chapter 2.02 - FIRE-RESISTIVE REQUIREMENTS AND STANDARDS FOR FIRE PROTECTION
 
SECTION 2.02.01: Fire-Resistive Requirements
 
(a) Exterior bearing and nonbearing walls of Types II and III constructions shall have one-hour fire-resistive rating; while those of types IV and V shall have four-hour fire-resistive rating.
 
(b) Interior bearing walls, permanent partitions, floors, and roofs of Types II to IV constructions shall have one-hour fire-resistive rating; while those of Type V shall have three-hour fire-resistive rating for walls, one-hour fire-resistive rating for partitions, and two-hour fire-resistive rating for vertical openings, floors, and roofs.
 
(c) Structural frames of Types II and III constructions shall have one-hour fire-resistive rating; those of Type IV shall have two-hour fire-resistive rating; and those of Type V shall have three-hour fire-resistive rating.
 
(d) Exterior doors and windows shall have three-fourths-hour fire-resistive rating for all types of construction.
 
SECTION 2.02.02: Fire-Resistive Standards
 
(a) General. Materials and systems of fire-resistive purposes shall be classified according to their fire-resistive ratings as determined by internationally accepted testing methods, subject to the provisions of this Section.
 
(b) One-Hour Fire-Resistive Time Period Rating
 
(1) The following walls and partitions shall have a one-hour fire-resistive rating: Solid masonry, 10 centimeters (4 inches) thick; hollow unit masonry, 15 centimeters (6 inches) thick; solid concrete, 10 centimeters (4 inches) thick; stud walls covered on each side with 1.9 centimeters (3/4 inch) lath and plaster, 1.6 centimeters (5/8 inch) of vermiculite gypsum board, or 2.5 centimeters (1 inch) of gypsum board; and 5 centimeters (2 inches) nominal thickness tongue and groove wood, or two layers of 1.9 centimeters (3/4 inch) tongue and groove wood separated by sheet metal or asbestos paper and treated on each side with a fire-retardant coating having a flame-spread rating of 50 or less. Square-edged boards may be used is the layers are laid at right angles with each other.
 
(2) The following floors shall have a one-hour fire-resistive rating: masonry or concrete, 10 centimeters (4 inches) thick; wood joists having two layers of flooring above and a plaster or gypsum board ceiling, 1.9 centimeters (3/4 inch) in thickness - the two layers of flooring shall be separated by sheet metal or asbestos building paper; 6.3 centimeters (2-1/2 inches) net thickness tongue and grooved wood floors covered with 1.9 centimeters (3/4 inch) wood flooring laid at right angles thereto. The supporting beams for such floors shall be not less than 15 centimeters (6 inches) in minimum dimension.
 
(3) The following protections for metal structural members shall have one-hour fire-resistive rating: 2.5 centimeters (1 inch) of concrete; 3.8 centimeters (1-1/2 inches) of masonry; and metal lath and 2.5 centimeters (1 inch) of plaster.
 
(4) The following shall also have a one-hour fire-resistive rating; wood colums, 20 centimeters (8 inches) or more in least dimension; and wood beams, 15 centimeters (6 inches) or more in least dimension.
 
(c) Two-Hour Fire-Resistive Time Period Rating
 
(1) The following partitions, walls, and floors shall have a two-hour fire-resistive rating: solid masonry, 15 centimeters (6 inches) thick; hollow unit masonry, 20 centimeters (8 inches) thick; and solid concrete, 127 centimeters (5 inches) thick.
 
(2) The following protections for metal structural members shall have a two-hour fire-resistive rating. 3.8 centimeters (1-1/2 inches) of concrete; 5 centimeters (2 inches) of masonry; and two layers of metal lath and plaster with 1.9 centimeters (3/4 inch) air space between and having a total thickness of 6.3 centimeters (2-1/2 inches).
 
(d) Three-Hour Fire-Resistive Time Period Rating
 
(1) The following partitions, walls, and floors shall have a three-hour fire-resistive rating: solid masonry, 17.8 centimeters (7 inches) thick; hollow unit masonry, 25.4 centimeters (10 inches) thick; and solid concrete, 15 centimeters (6 inches) thick.
 
(2) The following protection for metal structural members shall have a three-hour fire resistive rating: centimeters (2 inches) of concrete; 7.6 centimeters (3 inches) of masonry.
 
(e) Four-Hour Fire-Resistive Time Period Rating
 
(1) The following partitions, walls, and floors shall have a four-hour fire resistive rating: solic masonry walls, 20 centimeters (8 inches) thick; hollow unit masonry, 30 centimeters (12 inches) thick; and solid concrete, 17.8 centimeters (7 inches) thick.
 
(f) Steel Joists. Steel joist floors shall have from one to four-hour fire-resistive rating based on internationally accepted standards of engineering.
 
(g) Flame-Proof Materials. Materials required to be flame-proofed shall be treated with a flame-retardant having flame-spread rating of 50 less as determined by the "Tunnel Test".
 
SECTION 2.02.03: Interior Wall and Ceiling Finish
 
(a) General. Finishes for interior walls and ceilings of any building shall be classified according to their flame-spread characteristics using the internationally accepted "Tunnel Test" or other equivalent test for fire protection. The class of materials according to flame-spread characteristics shall be determined for each occupancy group. The smoke density shall not be greater than that obtain from the burning of untreated wood under similar conditions when tested in accordance with the "Tunnel Test" in the way intended for use. The products of combustion shall be no more toxic than the burning of untreated wood under similar conditions.
 
(b) Interior Finish Materials. Interior walls and ceiling finish shall mean interior wainscoting, paneling, or other finish applied structurally or for decoration, acoustical correction, surface insulation or similar purposes. Requirements for finishes shall not apply to trim, doors, and windows or their frames, nor to materials which are less than one millimeter (0.039 inch) in thickness cemented to an incombustible backing. Interior finish materials applied to walls and ceilings shall be tested as specified herein and regulated for purposes of limiting flame-spread.
 
SECTION 2.02.04: Promulgation of Fire-Resistive Regulations
 
(a) The Secretary shall promulgate appropriate standards and regulations on the testing of materials for flame-spread characteristics; application of controlled interior finish; finishes based on occupancy; materials and tests on fire dampers, fire tests of building construction and materials, fire tests of door assemblies, tin-clad fire doors, fire test of window assemblies, installation of fire door and fire windows, and smoke and fire detectors for fire protective signaling systems; fire-resistive protection of structural members; fire-resistive walls and partitions; fire-resistive floor-ceilings or roof-ceilings; fire-resistive assemblies for protection of openings; and fire-retardant roof coverings.
