Manage gas concentrations in tunnels and underground construction to ensure work safety.
This is a system that monitors the concentrations of oxygen (O2), flammable gases (methane: CH4), hydrogen sulfide (H2S), and carbon monoxide (CO), and alerts construction personnel of any detected anomalies. If the concentrations of these gases exceed or fall below the set reference values, an alarm will sound, enabling prompt action.
