XI issued important instructions on the gas explosion accident at Fuyang barbecue restaurant in Xingqing District, Yinchuan Province, demanding full treatment of the injured, strengthening safety supervision in key industries and areas, and ensuring the safety of people's lives and property

June 21,20:40 Xu, Yinchuan, Xingqing District Fuyang barbecue gas explosion accident. So far, the accident has caused 31 deaths and 7 injuries.

After the accident, General Secretary of the Communist Party of China, president and Central Military Commission President XI attached great importance to and gave important instructions. A gas explosion occurred at Fuyang barbecue restaurant in Xingqing District, Yinchuan, Ningxia, the loss of many lives is a painful and profound lesson. We must do our best to treat the wounded and comfort their families, find out the cause of the accident as soon as possible, and seriously investigate the responsibility according to law. It is now the Dragon Boat Festival Holiday, and all regions and relevant departments should firmly establish the concept of security and development, adhere to the People First, life first, with"Always at ease," a sense of responsibility, work to implement, keep an eye on potential dangers and thoroughly examine risks. In the near future, relevant departments should carry out a special rectification of work safety risks, strengthen safety supervision in key industries and fields, and effectively prevent the occurrence of serious and serious work safety accidents, we will ensure the safety of people's lives and property.

According to XI's instructions, the Ministry of Emergency Management, the Ministry of Housing and urban-rural Development, the National Health Commission and the General Administration of market supervision have dispatched working groups to the scene to guide the rescue and treatment of the wounded and emergency treatment. The Ningxia Hui Autonomous Region and Yinchuan have put together an all-out effort to deal with the aftermath. At present, medical treatment, accident investigation and other work is under way.

Article thirty-six of the new work safety law clearly stipulates that “If a production or business unit in the catering industry uses fuel gas, it shall install a fuel gas alarm device and ensure its normal use.”

Driven by the requirements of the new“Work Safety Law” and local policies, gas-fired production and business units such as the catering industry have basically installed combustible gas alarm devices, but why do accidents still occur frequently?

The traditional combustible gas alarm device needs regular adjustment, but as a restaurant business does not have the ability of regular adjustment, can not guarantee its normal use. After a few months the combustible gas alarm went off. There is an urgent need for a non-calibration, long-life flammable gas detector.

Due to the high cost of one-off purchase of laser products and the low safety awareness of restaurant vendors, they tend to choose low-cost one-off purchase of traditional detectors to be adjusted. But as the industry supervision department, it should take the responsibility of popularizing the safe and reliable technology and equipment on the issue of People's life safety. We will give top priority to the safety of the people's lives,” XI said.”

Passive fiber laser leakage monitoring system

The passive fiber laser leakage monitoring system consists of a monitoring platform, a photosensitive terminal and an electromagnetic valve. The monitoring platform is placed in the monitoring center, the photosensitive terminal is placed in the gas-using fire scene, and the solenoid valve is placed at the gas pipeline entrance. The platform is connected with the photosensitive terminal and the solenoid valve by optical fiber to form a gas safety monitoring network. Once the gas leak occurs, the system drives the solenoid valve to cut off the gas source immediately to prevent the explosion. When the unit air reaches the safety standard, the system automatically restores the air supply.

No power supply is required on site

The system mainframe can be installed dozens of kilometers away, and gas-fired monitoring sites only need to install passive photosensitive terminals (pure optical equipment, no power supply) . The real-time and on-line monitoring of combustible gas is realized by remote monitoring platform in the area where restaurants gather.

No calibration is required

The passive optical fiber laser leakage monitoring system does not need regular calibration and maintenance to ensure its normal use. No error report can improve the reliability of gas detection.

Long life

Using semiconductor light source, optical glass, no contact measurement, no physical loss, life up to 10 years. Therefore, the lifetime of passive fiber laser leakage detection equipment is 10 times that of traditional detection equipment.

More stable

The stability of traditional detection equipment is poor, and it is easy to be impacted and poisoned by the high concentration of gas leakage. This problem does not exist in passive fiber laser leak monitoring equipment. More stable performance.

Unique fire protection certification in laser industry

Laser on-line monitoring system for active internet of things

On-site visualization of gas monitoring concentration

With the display screen, the scene can be real-time display gas monitoring concentration, timely to avoid the occurrence of potential accidents.

Sound and light on-site alarm more intuitive

With on-site sound and light alarm function, fault prompt function. Gas leak the first time to remind the user, do a good job in a timely manner on-site staff evacuation.

More diverse means of communication

Can choose wired communications (RS485 or 4-20ma) , wireless communications (NB-Iot or 4G) , GPS or bluetooth communications, adapt to a variety of communication scenarios.

High protective performance

IP68 protection of the highest level, explosion-proof level up to Exd I a IIC T 6GB.
