In recent years, with the acceleration of industrialization and urbanization, various safety production accidents and environmental pollution incidents have occurred frequently, seriously threatening people’s life safety and health. Against this background, the demand for gas safety monitoring in the field of emergency rescue has become increasingly prominent. Gas sensors , with their excellent integration capabilities and powerful gas monitoring functions, have become an indispensable tool in emergency rescue work.
Gas sensors have a wide range of applications in the field of emergency rescue, playing a pivotal role from the prevention stage to the response stage to the recovery stage. In the prevention stage, by installing gas sensors, the concentration of various harmful gases in the environment can be monitored in real time, potential safety hazards can be discovered in a timely manner, and effective measures can be taken to intervene and avoid accidents. In the response phase, when an accident occurs, the gas sensor can quickly and accurately detect the type and concentration of harmful gases at the accident site, providing rescuers with scientific decision-making basis to ensure the safety and effectiveness of rescue operations. During the recovery stage, gas sensors also play an important role. They can help monitor the recovery of environmental quality and provide data support for subsequent reconstruction work.
In emergency rescue, commonly used gas sensor types include carbon monoxide (CO) sensor, oxygen (O₂) sensor, combustible gas (EX) sensor, hydrogen sulfide (H2S) sensor, ammonia (NH₃) sensor, volatile organic compounds (VOCs) ) sensor, sulfur dioxide (SO₂) sensor and carbon dioxide (CO₂) sensor, etc. Each of these sensors has unique detection functions and application ranges, and can fully cover various gas monitoring needs in emergency rescue.
For example, carbon monoxide sensors can detect carbon monoxide concentrations at accident sites and confined spaces, effectively preventing carbon monoxide poisoning accidents;
oxygen sensors are used to monitor oxygen concentrations in underground spaces, confined spaces, or environments after long-term combustion to ensure personnel safety. ;
Combustible gas sensors can promptly detect leaks of flammable gas or steam to prevent fire or explosion accidents;
hydrogen sulfide sensors are suitable for sewage treatment plants, mines and other places where there is a risk of hydrogen sulfide, effectively ensuring the safety of workers.
In addition to the detection of single gases, multi-gas sensors are also gradually receiving attention. It can detect multiple gases at the same time, such as carbon monoxide, oxygen, flammable gases and other toxic gases, and is suitable for comprehensive environmental monitoring. The emergence of this kind of sensor not only improves monitoring efficiency, but also reduces monitoring costs and provides more comprehensive and accurate data support for emergency rescue work.
