Experimental study on the influence of water mist activation time on the secondary ignition characteristics of discontinuous combustible materials in tunnels

Key Points

• Secondary ignition characteristics are significantly affected by the activation time of water mist, leading to safer tunnel environments.
• The study measured ignition responses in discontinuous combustible materials using specific water mist activation times for effective comparison.
• Assessment was done through experimental simulations in tunnel-like structures to provide detailed insights into fire behavior.
• Optimizing water mist activation time is crucial for enhancing fire safety in tunnels; further exploration is encouraged.
