Yantai Sancheng gas alarm security risks

The gas alarm is a safety valve that is produced by the company. If it fails, it will have a huge potential safety hazard. A few days ago, the Yantai City Metrological Institute had a total of 1200 gas detectors, of which 30% were in use with safety hazards, most of which were due to sensor aging.

It is understood that the gas alarm is a measuring instrument for safety protection. When the harmful gas leaks and reaches a certain concentration, the alarm is issued quickly. This is a safety device for preventing accidents. At present, the core device of a combustible gas alarm is a catalytic fuel sensor. Under normal use conditions, the sensor's sensitivity will naturally decline by 10% to 30% per year. Its life span is only 2 to 5 years. Once the aging does not achieve the alarm function, it will Cause serious security risks. According to the surveyed personnel, many enterprise managers in the city do not understand the working principle and technical characteristics of the alarms, or attach insufficient importance to the safety performance of the alarms, resulting in some unqualified alarms or non-performing periodic verifications. . At present, the Institute has dealt with related issues.
