An overview of emergency callers

Waterproof and moisture-proof telephones for non-coal mines and mines

It is well-known that accidents that occur in mines and mines in the country occur from time to time, and the positioning of underground personnel in the rescue work and the situation at the underground site are difficult to grasp. At this time, if the emergency assistance phone under the mine can be used to contact with the outside world, it will become even more important. Therefore, it is required that the phone must be able to be used normally for a long time in a high (tide) wet environment, when the mine or mine occurs. In the event of collapse or flooding, it must be able to call for help from the outside world.

Specific requirements:

1. High degree of protection, at least above IP66, in principle, as long as a person can speak, an emergency call must be able to function;

2. Emergency telephones are not usually used at ordinary times, but they must be used when they are used. Therefore, there are strict requirements for the quality and life cycle of SOS telephones.

Explosion-proof telephone for coal mines and oil wells

For coal mines, oil wells and other environments where there are a large number of flammable and explosive gases or liquids, combined with the major flooding and explosion accidents in coal mines, the emergency call for coal mines and oil wells must meet the requirements of waterproof and explosion-proof. In recent years, coal mine safety accidents have also increased year by year. According to incomplete statistics, from January 5th this year, the accident of Lisheng coal mine in Xiangtan County, Hunan Province, to the coal mine accident in Wangjialing Coal Mine, Shanxi Huajin, March 28th, 2010, and 4 On the 10th of this month, a total of 41 safety accidents occurred in Yihe Village, Yixing Village, Zhuyuan Town, Fengjie County, Qinghai Province. According to relevant data, even if the number of deaths in the Wangjialing Coal Mine were not counted, it had reached 135 people. The specific location of underground personnel is not sure to bring great difficulty to the rescue work.

In fact, as a member of an industrial telephone industry, every time I see these data, I feel very sad. So far, there is no good anti-explosion waterproof telephone in the country, and even some of them are holding the banner of "intrinsically safe" and selling it. Is an ordinary telephone external explosion-proof coupler, I do not know what they received the so-called explosion-proof certification is issued by the unit? How high is the credibility? And when the trend of certification in the industry does not recognize products, can people really be the center?
