Chapter 21: Tunnel Lighting, The NFPA provides two standards that address the design Chapter 22: Power Supply and Distribution, of tunnel system elements related to fire protection: Chapter 23: Water Supply and Drainage Systems, and Chapter 24: Surveillance and Control Systems. NFPA 130: Fixed Guideway Transit and Passenger Rail Sys- tems Standard [Ref. 2] and The recently published Handbook of Tunnel Fire Safety NFPA 502: Road Tunnels, Bridges, and Other Limited Access [Ref. 26] contains five parts addressing the key elements of Highways Standard [Ref. 5]. tunnel fire life safety: In addition, the NFPA provides guidelines for the design of Part I: Real Tunnel Fires, the fire protection and emergency response aspects of trans- Part II: Prevention and Protection, portation tunnels, including transit, rail, and road [Ref. 27]: Part III: Tunnel Fire Dynamics, Part IV: Fire Safety Management and Human 14.3 Fixed Guideway Transit and Passenger Rail Systems Factors, and 14.4 Rail Transportation Systems, and Part V: Emergency Procedures. 14.7 Fire Protection for Road Tunnels. 7.15 More Effective Fire Detection PIARC has in its library of published documents a report Systems entitled,"Fire and Smoke Control in Road Tunnels" [Ref. 27], Using the results from research like that noted in Section which contains technical chapters providing guidelines on the 7.5, researchers could continue to develop more advanced following: detection systems.
