NFPA 502: A Guide to Fire Safety Standards for Road Tunnels, Bridges, and Other Limited Access Highways

Road tunnels, bridges, and other limited access highways are critical infrastructures that facilitate transportation and commerce. However, they also pose unique fire hazards and challenges for fire protection and fire life safety. To address these issues, the National Fire Protection Association (NFPA) has developed NFPA 502: Standard for Road Tunnels, Bridges, and Other Limited Access Highways.

NFPA 502 is a comprehensive document that covers the design, construction, operation, maintenance, and emergency response of road tunnels, bridges, elevated highways, depressed highways, and roadways that are located beneath air-right structures. The standard aims to prevent fires, limit fire spread, protect structural integrity, facilitate evacuation, and enable effective firefighting and rescue operations in these facilities.

Some of the topics covered by NFPA 502 include:

Fire risk assessment and fire scenarios

Fire detection and alarm systems

Fire suppression systems

Ventilation systems

Lighting and emergency lighting systems

Emergency communication systems

Fire safety management and training

Emergency planning and coordination

Inspection, testing, and maintenance

NFPA 502 is intended for use by engineers, architects, contractors, owners, operators, authorities having jurisdiction (AHJs), fire departments, and other stakeholders involved in road tunnels, bridges, and other limited access highways. The standard is updated periodically to reflect the latest research, technology, and best practices in the field.

The current edition of NFPA 502 was published in 2020 and is available for purchase or free access online at of the benefits of complying with NFPA 502 include:

Enhancing the safety and security of road users and emergency responders

Reducing the likelihood and severity of fire incidents and their consequences

Minimizing the disruption and economic losses caused by fire incidents

Improving the performance and reliability of fire protection and fire life safety systems

Facilitating the coordination and cooperation among different stakeholders and agencies

Some of the examples of road tunnels or bridges that follow NFPA 502 include:

The EisenhowerâJohnson Memorial Tunnel in Colorado, USA, which is the highest vehicular tunnel in the world and has a sophisticated fire detection and suppression system

The Channel Tunnel between France and the United Kingdom, which is the longest undersea tunnel in the world and has a dedicated fire safety authority and a comprehensive emergency plan

The Hong KongâZhuhaiâMacau Bridge in China, which is the longest sea-crossing bridge in the world and has a state-of-the-art ventilation system and a fire safety management system ec8f644aee
