Tunnel Emission Monitoring
Tunnel emission monitoring involves the measurement and assessment of pollutants released into the atmosphere of the tunnel, particularly road tunnels and underground transportation systems. It helps ensure compliance with air quality standards, assess the effectiveness of pollution control measures, and protect the health and safety of tunnel users and nearby communities.
Exhaust Gas Monitoring
Monitoring the exhaust gases emitted by vehicles passing through the tunnel is crucial. It involves measuring pollutants such as nitrogen oxides (NOx) and carbon monoxide (CO) to assess their levels and compliance with regulatory limits.
Air Quality Monitoring
Monitoring the ambient air quality in and around the tunnel is important to assess the impact of emissions on nearby communities. This involves measuring pollutant levels such as NOx, PM, CO, Visibility and Light at various monitoring stations located within the tunnel, near the tunnel exits or in the surrounding areas.
Carbon Monoxide Monitoring
Carbon monoxide (CO) is primarily emitted from vehicle exhaust and can pose a risk to tunnel users if concentrations exceed safety thresholds. Continuous monitoring of CO levels ensures prompt detection of any anomalies and timely response to mitigate risks.
Monitoring visibility within the tunnel is important for the safety of drivers. CODEL monitoring systems can measure factors such as air flow, light levels and visibility range to ensure adequate visibility and alert authorities in case of poor visibility conditions.
Tunnel emission monitoring is often required to ensure compliance with local and national air quality standards and regulations. Regular monitoring, reporting, and data analysis are essential for demonstrating compliance and identifying areas that require improvement.
The TunnelTech 200 Series Air Quality Monitors can continuously monitor CO, NO & visibility within road and rail tunnels. Monitoring of these vital gases ensures that the tunnel ventilation system provides sufficient clean air to protect tunnel users health and for drivers to clearly see the road ahead.
