In the past few months, it happened"6 · 13" Major Gas Explosion Accident in Shiyan City, Hubei ProvinceMany people should still be impressed by its bad influence and profound lessons, which has also caused the society to attach great importance to the safety of urban pipeline gas. In recent years, various localities have stepped up the investigation of hidden dangers of pipeline gas, in order to put an end to all kinds of hidden dangers in the bud.

Zui's newly revised "the People's Republic of China Safety Production Law" has been formally implemented on September 1 this year, which stipulates mandatory regulations for the installation of combustible gas alarm devices by production and business units in catering and other industries. Article 36 of the new "Safety Production Law" clearly stipulates: "If production and business units in catering and other industries use gas, they shall install combustible gas alarm devices and ensure their normal use."

The new "Safety Production Law" includes catering and other industries production and business units.Combustible gas alarm device not installed for used gasThe nine major acts have clearly defined the punishment standard: order to make corrections within a time limit and impose a fine of less than 50,000 yuan; If it fails to make corrections within the time limit, it shall be fined not less than 50,000 yuan but not more than 200,000 yuan, and the person in charge and other persons directly responsible shall be fined not less than 10,000 yuan but not more than 20,000 yuan. If the circumstances are serious, they shall be ordered to suspend production or business for rectification. The new "production safety law" will increase the punishment for illegal acts, and the fine amount will be higher. The fine amount for especially serious accidents can reach 0.1 billion yuan. Increasing the penalties for violations and raising the cost of violations reflects the importance attached to safe production,"Whoever dares to ignore safe production may be fined and ruined"；

This also means that starting from September 1 this year, production and business units that use gas in the catering industry will install gas alarms one after another. Relevant government departments will also increase the intensity of guidance and even mandatory installation of gas alarms from the regulatory level in the future.

Catering and other industries should install combustible gas alarm devices

In view of the safety hidden problems existing in gas users in catering and other industries, as well as the irregular use of alarm equipment related to production safety, Article 33 is changed to Article 36, and two paragraphs are added as paragraphs 3 and 4:
"Production and business units shall not close or destroy monitoring, alarm, protection, life-saving equipment and facilities directly related to production safety, or tamper with, conceal or destroy their relevant data and information.
"If production and business units in catering and other industries use gas, they shall install combustible gas alarm devices and ensure their normal use."

Promoting "Internet Emergency Management"
The new safety law proposes that "the emergency management department of the State Council shall take the lead in establishing a unified national emergency rescue information system for production safety accidents. The relevant departments of transportation, housing and urban and rural construction, water conservancy, civil aviation and other relevant departments of the State Council and local people's governments at or above the county level shall establish and improve the emergency rescue information system for production safety accidents in relevant industries, fields and regions to realize interconnection and information sharing, Through the implementation of online safety information collection, safety supervision and early warning, improve the precision and intelligent level of supervision".

Recently, safety production investigation and rectification actions have been carried out across the country. Many companies that have hidden dangers in safety production and the selection of combustible gas alarms that do not meet the requirements have been fined, notified, or even closed for rectification, and reported to the person in charge of the company and procurement. Responsible personnel are held accountable. This shows the importance of the correct selection of combustible gas alarm.

How to choose a combustible gas alarm?

When choosing a combustible gas alarm, it is necessary to choose according to whether the gas used is natural gas, liquefied gas or other types of combustible gas. The gas composition of different regions is different, should use the local gas composition calibration and detection of combustible gas alarm.

The core component of the household combustible gas alarm is the combustible gas sensor, and the technology recommend is the low-power gas sensor.TGS3870The TGS3870 is a semiconductor gas sensor that can simultaneously monitor gas and carbon monoxide. Due to the use of the microbead type gas sensing structure, by applying periodically varying high and low voltages to the heater of the sensor, it is possible to allow a sensor to detect both methane and carbon monoxide gases. Moreover, the gas sensor is very small, and the power consumption of the heater is only 38mW (average).

TGS3870-B00 is extremely sensitive to the typical interfering gas ethanol vapor in the living environment and is very durable, so it is the ideal sensor for the gas alarm market.

Methane/carbon monoxide dual gas sensor TGS3870 main parameters:
Methane detection range: 500-12500ppm
Carbon monoxide detection range: 50-1000ppm
Methane sensitivity (resistance ratio):0.50-0.65
Carbon monoxide sensitivity (resistance ratio):0.1-0.6
Circuit voltage: 5V ± 0.2V(DC, pulse)
