NFPA 502-2020 PDF Download

NFPA 502-2020 is a comprehensive document that provides guidelines and requirements for addressing fire protection and life safety challenges in road bridges, tunnels, and limited-access highways. The standard encompasses various aspects such as construction, operation, maintenance, and fire protection of these structures.

This international standard covers a wide range of topics including emergency systems and response, traffic control and communications, ventilation, means of egress, electrical systems, standpipe and water supply, and control of hazardous materials. It offers detailed provisions and critical information for mitigating risks and safeguarding lives in these limited access areas.

The 2020 edition of NFPA 502 incorporates the most current industry best practices and technological developments. It includes several updates and additions that enhance the standard, such as clarifying that protection methods assume a single fire event, requiring analysis on non-conventional and non-grid connections, providing further explanations for fixed-water-based fire-fighting systems, updating the section on Operations Control Centers (OCCs), introducing a new requirement for structural fire protection materials, and referencing NFPA 72, the National Fire Alarm and Signaling Code, for automatic fire detection systems.
