Applications of Handheld Gas Detectors & Detector Solutions
At present, relevant departments in some urban areas have stipulated that mining workers must be equipped with portable gas detection and alarm devices and self rescue devices when going underground. Why is gas detection device an essential equipment for underground workers?
At least a few people die in mining accidents every year in the world, and the frequency of occurrence is particularly prominent in developing countries such as China. In 2003, China produced about 35% of the world's coal, but accounted for about 80% of the deaths in coal mine accidents.
There may be various reasons for mining accidents, including toxic gas or natural gas explosions (such as methane), coal powder explosions, seismic activity, hydrological or mechanical failures, and pointing errors.
Toxic gases, on the other hand, are the least detectable. A single gas detector can accurately measure over 21 types of toxic and harmful gases, including oxygen.
The mining explosion-proof portable carbon monoxide detection alarm has simple and convenient dual button operation; Ultra large visual display, easy to perceive instrument information; Durable and reliable shell design ensures easy handling under harsh conditions; Users can quickly obtain alarm information through red LEDs.
Functional testing and calibration operations can be easily completed manually or managed through the MP300T1 automatic calibration and management platform.
Therefore, all types of anti loosening equipment used underground in coal mines must comply with the national standard "GB3836-2000"
If the explosion-proof equipment is not qualified, the flame of the internal explosion will spread to the outside and come into direct contact with the combustible and explosive mixed gas underground, which may cause mine fires and gas or dust explosions, resulting in major malignant accidents. In enclosed places such as sewers, agricultural enclosed grain warehouses, railway tankers, roads, etc., personnel must be tested before entering the workplace, and testing must be carried out outside the enclosed space. A complete enclosed space gas alarm should be non-contact and have multiple gas detection functions to detect dangerous gases distributed in different spaces, and should be a portable heart device that does not affect workers' work.
