H2s detector are often installed in tunnel construction to detect the concentration of toxic and harmful gases in the tunnel.
At present, with the construction of my country's road and railway transportation network, it is becoming more and more perfect. In the construction of these transportation networks, tunnels are often encountered. There are often a lot of toxic and harmful gases in the tunnel. , These gases have always been the main source of danger to the health and safety of construction workers. If the construction is improper, major safety accidents are very prone to occur. For example, in tunnel construction, h2s detector is used to detect the concentration of hydrogen sulfide gas.
Hydrogen sulfide gas is a colorless, flammable acid gas. Hydrogen sulfide can explode when the concentration in the air ranges from 4.3% to 45.5%. Hydrogen sulfide gas is highly toxic. A small amount of low concentration can cause tearing and coughing. Symptoms such as chest tightness and fatigue occur. If the human body inhales a small amount of high-concentration hydrogen sulfide gas, it may be fatal in a short time.
Therefore, it is necessary to monitor hydrogen sulfide gas in strict accordance with relevant regulations during construction. In addition, key monitoring is carried out on coal-measure strata and strata with high gas content. And depending on the situation, increase the density of monitoring sections. At the same time, it is also necessary to make records of changes in the concentration of various toxic and harmful gases. And timely and accurate summary to the organization and command system. Sorting out and analyzing the monitoring data of toxic and harmful gases. It is to ensure that construction and production are carried out in an orderly manner under the premise of safety.
h2s detector can continuously monitor online for 24 hours. The detection data is uploaded to the cloud platform in real time. View data through computer web pages, mobile apps, applets, etc. Support exporting historical data, linkage alarm function, etc.
