At present, relevant departments of some urban areas stipulate that mining mountain workers must be equipped with portable gas detection alarms and self-rescuers. It is understood that the portable gas detection alarm device has built-in gas sensor detection components, which can automatically measure the gas in the well. When the harmful gas content exceeds the standard or the oxygen is insufficient, it will automatically alarm.
The self-rescuer is required for every worker to go down the well. In the event of a fire or poor air quality, the worker can remove the self-rescuer and open it, and plug the mouth to save himself.
Gas detection According to different field environments, the corresponding gas alarm and gas sensor should be selected.
In confined spaces, the following waterways, agricultural closed granaries, railways
In tank cars, tunnels, etc., before personnel enter, they must be tested and tested outside the confined space. At this point, it is necessary to select an alarm with built-in multi-gas detection function, because the gas distribution and gas type in different parts of the confined space are very different.
Therefore, a complete confined space gas alarm should be a non-contact, sub-site detection with multi-gas detection function to detect dangerous gases distributed in different spaces, and should be a portable instrument that does not affect the work of workers. Only in this way can the absolute safety of the personnel entering the confined space be guaranteed.
The gas detector is a gas sensor that detects the composition and concentration of gas. It is used in some mines and other places where safety hazards are hidden, which greatly reduces the occurrence of some possible mine disasters.
The gas composition in the mine represents a variety of hazardous conditions, including toxic gases such as carbon monoxide, carbon dioxide, and sulfur dioxide, as well as insufficient oxygen. In some cases, methane may also reach explosive concentrations.
Therefore, at present, in many underground gas detection equipment, different types of gas sensors, such as oxygen sensors, carbon dioxide sensors, carbon monoxide sensors, etc., are installed. Complex gas compositions and concentrations are detected by replacing different gas detection probes.
