Harvey brings decades of tunnel engineering experience to international committee setting fire safety standards for road tunnels, bridges and other limited access highways
NEW YORK, NY. (Jan. 15, 2025) — Norris Harvey, PE, HNTB’s practice leader for fire life and safety and tunnel ventilation, has been reappointed chair of the National Fire Protection Association’s (NFPA) 502 Committee, an international organization that sets the standard for fire protection and life safety in road tunnels, bridges and other limited-access highways.
The NFPA 502 Committee comprises 30 members from 10 countries and is responsible for maintaining a consensus standard that is internationally recognized and adopted. The standard is updated every three years to reflect advances in fire suppression, ventilation and emerging vehicle technologies.
Over the past three decades, Harvey has contributed to the design and rehabilitation of more than 50 highway tunnels and six transit systems across the U.S. and is recognized for his expertise in tunnel ventilation, fire protection and emergency response systems.
“Tunnel safety is constantly evolving, and our committee’s work ensures NFPA 502 remains a living document that addresses new risks and technologies,” Harvey said. “I’m honored to lead this group of industry experts again as we continue to advance best practices for the safety of the traveling public.”
Sanja Zlatanic, HNTB’s national tunnel practice leader, said Harvey’s appointment underscores HNTB’s commitment to safety and innovation.
“Norris’s leadership and technical expertise have set a high standard in tunnel ventilation and fire and life safety engineering,” said Zlatanic. “As chair of the NFPA 502 Committee, he is well positioned to help advance the industry, supporting agencies and communities nationwide. Throughout his career, Norris has earned a strong reputation within the profession, and our clients have developed a high level of trust and confidence in his expertise.”
NFPA 502 integrates active and passive safety measures, including egress provisions, emergency ventilation and structural protection. The latest edition emphasizes performance-based, risk-informed design and also addresses new challenges such as alternative fuel vehicles and autonomous technologies.
