Case Study: Confined Space Continuous Gas Monitor in Railway Construction
The Challenge: Extreme Confined Space Hazards
In major infrastructure projects like the Shenshan High-speed Railway, underground tunnel excavation creates severe confined space hazards. The presence of heavy machinery, such as generators and compactors, combined with poor ventilation, requires a highly reliable fixed multi-gas detector. It must continuously monitor both toxic gases released from the ground and exhaust emissions from machines to ensure worker safety.
Real-Time Monitoring Data for Ex, O2, H2S, and CO
Our industrial-grade device effectively tracks four critical gas levels simultaneously. Based on the real-time site data shown on the device screen, all indicators are currently in the normal and safe range:
Ex (Combustible Gas)
Current Value: 3.3 %LEL (Range: 100.0 %LEL). This effectively tracks explosive gases like methane and coal gas, preventing them from reaching the lower explosive limit and causing accidents.
O2 (Oxygen)
Current Value: 21.06 %VOL (Range: 25.00 %VOL). This reading confirms a standard fresh air level. Monitoring oxygen is crucial to prevent hypoxia and asphyxiation for workers in enclosed underground environments.
H2S (Hydrogen Sulfide)
Current Value: 0.0 ppm (Range: 100.0 ppm). H2S is a highly toxic gas often released from deep soil or mud during excavation. The zero reading indicates a safe zone with no toxic gas accumulation.
CO (Carbon Monoxide)
Current Value: 6.5 ppm (Range: 500.0 ppm). A trace amount is detected, which is very common on construction sites. This typically originates from the incomplete combustion exhausts of fuel-powered machinery running in the tunnel.
Why Choose Our Industrial Gas Detector
As a professional industrial gas detector manufacturer, we prioritize durability and engineering safety. The device features a heavy-duty explosion-proof aluminum alloy housing built for high-dust, high-vibration environments. Furthermore, our professional installation standard ensures a clean setup with no visible wires exposed. This strictly compliant design significantly reduces the risk of accidental cable damage during heavy construction, providing true peace of mind for safety managers.
