Tackle today’s structural protection and emergency readiness challenges to reduce hazards and help safeguard lives.
Introducing your updated fire and life safety sidekick: NFPA® 502, Standard for Road Tunnels, Bridges, and Other Limited Access Highways—the international standard for limited access highways, road tunnels, bridges, elevated highways, depressed highways, and roadways that are located beneath air-right structures. With comprehensive provisions for ventilation, means of egress, electrical systems, standpipe and water supply, and traffic control and communications, NFPA 502 is essential for designers, engineers, architects, authorities having jurisdictions (AHJs), and state and federal regulators.
The 2023 update also includes:
New Annex D that provides guidance on controlling smoke formation in tunnels with critical velocity calculation methods
Recategorization of tunnels to reduce the number of categories
New requirements covering safety features required for Category A tunnels
Updates to Annex G to incorporate the latest developments and hazards for alternative fuel vehicle technology
Updated requirements to address recognition of various non-listed systems
Added references to other standards for the use of alternative time-temperature curves when testing passive fire protection materials
