Passive Fire Protection (PFP) Tunnel Systems are engineered to enhance the fire safety of tunnels and underground infrastructure. These systems use fire-resistant materials and construction techniques to contain fire, prevent its spread, and maintain the structural integrity of tunnels during high-temperature events.
For expert consultation, design, and installation of passive fire protection tunnel systems, contact Reliance Fire Protection Systems. We deliver end-to-end solutions tailored to your tunnel safety requirements.
Fire-Resistant Linings: Special panels or sprays applied to tunnel walls and ceilings to withstand high temperatures and protect concrete and steel structures.
Fire Barriers & Compartmentation: Barriers and partitions that divide tunnels into sections, limiting fire and smoke spread.
Fire-Resistant Coatings: Intumescent or cementitious coatings that expand or insulate under heat, protecting surfaces from fire damage.
Fireproof Insulation: High-performance insulation materials to protect cables, pipes, and critical systems.
Fire Doors & Seals: Certified fire doors and expansion joint seals to maintain compartmentation and block fire paths.
