NFPA 502 revisions and a new mandate for integrated testing help you improve the fire protection and life safety of today’s road tunnels and bridges. From emergency egress to communications issues, limited-access highways, tunnels, bridges, elevated highways, and air right structures present a host of unique fire protection and life safety challenges. The 2017 edition of NFPA 502: Standard for Road Tunnels, Bridges, and Other Limited Access Highways provides designers, engineers, AHJs, and state and federal regulators with the latest guidelines for the construction, operation, maintenance, and fire protection of these venues to mitigate hazards, maintain structural integrity, and protect lives. This important international Standard also covers traffic control, standpipe and water supply, control of hazardous materials, emergency ventilation, electrical systems, and emergency response. Designers, engineers, architects, and AHJs will work more confidently to address risks and implement appropriate safety systems with this edition. Added guidance for conducting an engineering analysis includes a revised list of considerations to be taken into account, along with more guidance in the Annexes. Integrated testing on fire protection, life safety, and emergency systems is now required in accordance with NFPA 4: Standard for Integrated Fire Protection and Life Safety System Testing. Modified requirements for the structural protection of bridges will assist designers, engineers, architects, and AHJs. Annex B includes guidance on establishing noise levels in order to maintain a minimum level of speech intelligibility through the emergency communication system. The constant K1 used in the critical velocity equation of Annex D has been modified and is no longer a constant for heat release rates (HRR) less than or equal to 100 MW. Annex E presents new information regarding the effects of fire suppression on HRR and tunnel ventilation. New Annex M adds guidance on the use of automatic fire detection systems in road tunnels. Apply the latest requirements to safeguard the public on limited-access highways, road tunnels, and bridges.
