in area shall comply with Sections 402.12.1 through 402.12.4.
402.12.1
Materials. Children's
playground structures shall be constructed of noncombustible materials or of
combustible materials that comply with the following:
1.
Fire-retardant-treated
wood complying with Section 2303.2.
2. Light-transmitting plastics complying with
Section 2606.
3. Foam plastics
(including the pipe foam used in soft-contained play equipment structures)
having a maximum heat-release rate not greater than 100 kilowatts when tested
in accordance with UL 1975.
4.
Aluminum composite material (ACM) meeting the requirements of Class A
interior finish in accordance with Chapter 8 when tested as an
assembly in the maximum thickness intended for use.
5. Textiles and films complying with the
flame propagation performance criteria contained in NFPA 701.
6. Plastic materials used to construct rigid
components of soft-contained play equipment structures (such as tubes, windows,
panels, junction boxes, pipes, slides and decks) exhibiting a peak rate of heat
release not exceeding 400 kW/m2 when tested in
accordance with ASTM E 1354 at an incident heat flux of 50
kW/m2 in the horizontal orientation at a thickness
of 6 mm.
7. Ball pool balls, used
in soft-contained play equipment structures, having a maximum heat-release rate
not greater than 100 kilowatts when tested in accordance with UL 1975. The
minimum specimen test size shall be 36 inches by 36 inches (914 mm by 914 mm)
by an average of 21 inches (533 mm) deep, and the balls shall be held in a box
constructed of galvanized steel poultry netting wire mesh.
8. Foam plastics shall be covered by a
fabric, coating or film meeting the flame propagation performance criteria of
NFPA 701.
9. The floor covering
placed under the children's playground structure shall exhibit a Class I
interior floor finish classification, as described in Section
804, when tested in accordance with NFPA 253.
402.12.2

Children's playground structures located within the mall shall be provided with
the same level of approved fire suppression and detection
devices required for kiosks and similar structures.
402.12.3
Separation. Children's
playground structures shall have a minimum horizontal separation from other
structures within the mall of 20 feet (6090 mm).
402.12.4
Area limits. Children's
playground structures shall not exceed 300 square feet (28
m2) in area, unless a special investigation has
demonstrated adequate fire safety.
