At around 6:00 am on July 31, a suspected gas explosion occurred at Jiu Hao canteen, 198 Qianlong Olympic Sports City, Cangshan District, Fuzhou. Two restaurant employees and a passer-by were 2023 at the scene, three people were injured and are not in critical condition.

On the 30th, the national safety production teleconference was held in Beijing. Zhang Guoqing, Vice Premier of the State Council and Chairman of the State Council Security Committee, attended the meeting and delivered a speech. Wang Xiaohong, State Councilor and vice chairman of the State Council Security Committee chaired the meeting. The meeting stressed the need to resolutely implement the guidelines issued by General Secretary Xi and Premier Li Qiang's requirements, learn from the lessons learned from the recent accident, accurately investigate and rectify potential accident risks, and make solid efforts in work safety, we will effectively prevent and contain major accidents.

The meeting stressed the need to firmly establish the concept of safety development, eliminate the idea of“Making efforts after the event”, adhere to the eyes down, staring at the line, sinking regulatory power, strict supervision and law enforcement, focus on accident-prone industry, high-risk sites, and so on, pay close attention to the terminal terminal end of the main responsibility implementation, risk bottom-up investigation, root cause and eradicate hidden dangers. We must strictly implement the responsibility review mechanism, promote accountability to extend forward, to ensure comprehensive coverage of the investigation and rectification, thorough investigation and true change. We should comprehensively carry out a comprehensive control of fuel gas safety, focusing on such key links as defective gas, defective bottles, defective valves, defective hoses, defective pipe networks, defective environments, and so on, we will resolutely curb the growth of gas accidents. We should strengthen science and technology to ensure safety, speed up the safety transformation of old facilities and equipment, vigorously cultivate safety culture, and strive to tamp down the Safety Foundation. 

Why frequent gas accidents in the catering industry?

Because of the lack of safety awareness, the restaurant vendors tend to choose the traditional detectors that need to be adjusted because of the lower one-time purchasing cost. The restaurant vendors do not have the ability to adjust their own equipment, time for a long time the detector has been virtually useless. In the case that there seems to be monitoring but there is no monitoring, the explosion accident is inevitable.

The technology principle of point laser methane sensor determines that it does not need to be adjusted and can run stably for a long time. The anti-interference characteristic of optics makes it completely immune from the electromagnetic interference of wet steam, high temperature and motor in the operating room. Millisecond reaction speed can be issued in an instant command to cut off the gas source. The possibility of an accident is technically ruled out. Therefore, it is a feasible method to replace electrochemical detector with laser detector for gas safety in catering industry.

Point laser methane sensor

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

You can choose cable communication (Modbus-RTU or 4-20mA) , wireless communication (4G or NB-loT) , 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.

Strong anti-interference

Free from humidity, dust, temperature and other gases, can work in a high humidity environment for a long time.

Internet of things technology is available

The area covered by the network can be used regardless of distance and range.

Easy installation

Point laser methane sensor is a stand-alone instrument, just need to replace the original electrochemical detector into a laser detector, and the original fire control by the original connection on the way it can be connected. The replacement work is very simple.
