Gas Explosion at Barbecue Restaurant in Yinchuan, Ningxia: 31 Deaths Reported
Xi Jinping issued an important instruction on the gas explosion accident at Fuyang Barbecue Restaurant in Xingqing District, Yinchuan City, Ningxia Hui Autonomous Region, demanding all-out efforts to treat the injured, strengthen safety supervision in key industries and fields, and effectively safeguard the people's lives and property safety.
At around 20:40 on June 21, a gas explosion occurred at Fuyang Barbecue Restaurant in Xingqing District, Yinchuan City, Ningxia Hui Autonomous Region. Up to now, the accident has caused 31 deaths and 7 injuries.
After the accident, Xi Jinping, General Secretary of the Communist Party of China Central Committee, President of the People's Republic of China, and Chairman of the Central Military Commission, attached great importance to it and made important instructions. The gas explosion at Fuyang Barbecue Restaurant in Xingqing District, Yinchuan City, Ningxia, has caused heavy casualties, which is distressing and leaves a profound lesson. All-out efforts should be made to treat the injured and comfort the families of the casualties, the cause of the accident should be found out as soon as possible, and responsibilities should be seriously pursued in accordance with the law. Currently, it is the Dragon Boat Festival holiday. All regions and relevant departments must firmly establish the concept of safe development, adhere to the people-first and life-first principle, implement work with a sense of responsibility of "being on tenterhooks all the time", keep an eye on potential hazards, and conduct a comprehensive risk investigation. In the near future, relevant departments should carry out a special rectification of production safety risks, strengthen safety supervision in key industries and fields, effectively prevent the occurrence of major and extraordinarily serious production safety accidents, and truly protect the people's lives and property.
In accordance with Xi Jinping's instructions, the Ministry of Emergency Management, the Ministry of Housing and Urban-Rural Development, the National Health Commission, and the State Administration for Market Regulation have sent working groups to the scene to guide the treatment of the injured and emergency disposal work. Ningxia Hui Autonomous Region and Yinchuan City have organized forces to fully carry out the aftermath work. At present, medical treatment and the investigation into the cause of the accident are underway.
Article 36 of the newly revised Work Safety Law clearly stipulates: "Production and business units in the catering and other industries that use gas shall install combustible gas alarm devices and ensure their normal use."
Driven by the requirements of the new Work Safety Law and local policies, production and business units using gas in the catering industry and other sectors have basically installed combustible gas alarm devices, but why do accidents still occur frequently?
Traditional combustible gas alarm devices require regular calibration, but catering businesses do not have the ability to perform regular calibration, making it impossible to ensure their normal use. After a few months, the combustible gas alarms become useless. At present, there is an urgent need for a combustible gas detector that requires no calibration and has a long service life.
In response to the safety status of the catering industry, Hanhai Optoelectronics has developed the Passive Optical Fiber Laser Leakage Monitoring System and the Active Internet of Things Laser Online Monitoring System. Both products require no calibration and have a service life of up to 10 years. They are new technical products with higher safety and reliability and lower comprehensive costs, which can prevent gas explosion accidents caused by gas leakage in the catering industry.
Given that the one-time purchase cost of laser products is relatively high, catering businesses, due to weak safety awareness, tend to choose traditional detectors that require calibration with lower one-time purchase costs. However, as industry supervision departments, on issues related to people's lives, they should assume the responsibility of promoting safe and reliable technical equipment, and effectively implement General Secretary Xi Jinping's instruction that "always put the people's lives and safety first".
Passive Optical Fiber Laser Leakage Monitoring System
The Passive Optical Fiber Laser Leakage Monitoring System consists of a monitoring platform, optical sensing terminals, and solenoid valves. The monitoring platform is placed in the monitoring center, the optical sensing terminals are installed at the gas and fire use sites, and the solenoid valves are placed at the gas pipeline entrances. The platform is connected to the optical sensing terminals and solenoid valves via optical fibers, forming a gas safety monitoring network. Once a gas leak occurs, the system immediately drives the solenoid valve to cut off the gas source to prevent explosions. When the air quality at the gas and fire use unit meets safety standards, the system automatically resumes gas supply.
No On-site Power Supply Required
The system host can be installed dozens of kilometers away, while only passive optical sensing terminals (pure optical equipment with no power supply required) need to be installed at the gas and fire monitoring sites. For areas with concentrated catering businesses, real-time online monitoring of combustible gases is realized through a remote monitoring platform.
No Calibration Needed
The Passive Optical Fiber Laser Leakage Monitoring System does not require regular calibration and maintenance, ensuring its normal use. The absence of false alarms improves the reliability of gas detection.
Long Service Life
Adopting semiconductor light sources and optical glass, it uses non-contact measurement with no physical wear and tear, and has a service life of up to 10 years. Therefore, the service life of the passive optical fiber laser leakage monitoring equipment is 10 times that of traditional detection equipment.
Higher Stability
Traditional detection equipment has poor stability and is prone to damage and failure due to high concentrations of gas leakage, while the passive optical fiber laser leakage monitoring equipment is free from such problems and has more stable performance.
The Only Fire Certification in the Laser Industry
Active Internet of Things Laser Online Monitoring System
On-site Visualization of Gas Monitoring Concentration
Equipped with a display screen, it can display gas monitoring concentrations in real time on-site, timely avoiding potential accidents.
Intuitive On-site Sound and Light Alarm
It has on-site sound and light alarm functions and fault prompt functions. In the event of a gas leak, it alerts users at the first time to facilitate the timely evacuation of on-site personnel.
Diverse Communication Methods
It can adopt wired communication (RS485 or 4-20mA), wireless communication (NB-IoT or 4G), GPS or Bluetooth communication, adapting to various communication scenarios.
High Protection Performance
It has the highest protection level of IP68 and an explosion-proof grade of Exd ia IIC T6 Gb.
