background
Reasons for toxic and harmful gas monitoring. On May 24, 2021, a toxic and harmful gas suffocation accident occurred in the Furong Bamboo Shoots Food Factory in Changning County, Yibin City, Sichuan Province during the maintenance of its facilities. Five ambient air monitoring points were set up around the Changning County Furong Bamboo Shoots Food Factory. And three monitorings were carried out. The monitoring results show that the hydrogen sulfide and ammonia in the surrounding air are below the pollutant emission standards.
On the afternoon of May 24, the sewage treatment system was reopened during the company's maintenance operations. Causing the overflow of toxic and harmful gases such as hydrogen sulfide in the sewage. Causing the poisoning of 2 employees who were working. And then 6 people (3 employees of the company, 3 residents around the plant) ) Successively went to rescue and caused poisoning. The accident caused a total of 8 people to be poisoned, of which 7 died and 1 was slightly injured. They were temporarily out of danger and all vital signs were normal. This tragic incident tells people that the constant monitoring of toxic and harmful gases is the top priority. This will not only protect the lives of employees but also reduce the company's losses.
The role of toxic and harmful gas monitoring
The explosion-proof all-in-one gas detector independently developed by Jingxunchangtong is an industrial gas safety detection instrument designed in accordance with the national standards GB15322.1-2003 and GB12358-2006. The explosion-proof all-in-one gas detector adopts a dual-chamber structure design, and the protection level is IP65. It is suitable for detecting combustible, toxic and harmful gases in chemical, outdoor irrigation areas and other environments. It has accurate measurement, fast response, strong anti-interference ability, and can be applied to Gas monitoring in various harsh environments.
The gas alarm controller includes two specifications: digital tube display and color screen display. The data readings detected by the sensor are summarized on the display screen for display. At the same time, according to the settings, the controller will perform a series of alarm actions after the current data is greater than the alarm concentration. Such as Sound and light alarm, exhaust, power failure, etc. (according to customer settings), the gas alarm controller can support a control system with up to 16 sensor inputs. Support two-way relay control, and can link air exhaust and power failure.
