321.2.1 Fire scenario design parameters.

Approved fire scenarios used for designing fixed guideway transit and passenger rail systems shall be in accordance with Sections 4.4 and A 4.4.2 of NFPA 130, as modified by FC Appendix B, and the following:

   1.   The worst case scenario, as set forth in NFPA 130, as modified by FC Appendix B, shall be used for both the station and trainway designs.

   2.   Computational fluid dynamics analysis for the fire simulation shall be performed for an approved period of time, both with and without mitigating systems, including but not limited to ventilation and sprinkler protection.

   3.   The tenable condition parameters reported in the computational fluid dynamics analysis, including but not limited to heat, visibility and carbon monoxide, shall be precisely reported in the analysis.

321.3 Operation and maintenance.

The operation and maintenance of fixed guideway transit and passenger rail systems shall be in accordance with NFPA 130 and all Annexes thereto, as modified by FC Appendix B.

321.4 Construction site fire safety.

Construction operations of fixed guideway transit and passenger rail systems, including stations and tunnels, shall be conducted in accordance with Chapter 33 of the Building Code; this code, including FC Chapter 33; and NFPA 130, as modified by FC Appendix B. Approved fire extinguishing systems shall be provided for construction shanties and construction storage facilities and areas.
