June this year is the 21st national "safety production month", with the theme of "observing the safety production law and being the first responsible person". The newly revised work safety law clearly stipulates that the main person in charge of the production and business operation unit is the first person responsible for the work safety of the unit and is fully responsible for the work safety of the unit.

In order to further promote the principal responsible person of an enterprise to perform the duties of the first responsible person and play the role of "key minority", the emergency management department recently announced a number of typical law enforcement cases. In law enforcement activities, administrative penalties were imposed strictly according to law not only on the enterprises that had illegal acts, but also on the illegal acts of the principal responsible person of the enterprise that did not perform their statutory duties, urging the principal responsible person of the enterprise to take the lead in respecting, learning, abiding by and using the law, Consciously put safety first, strictly strengthen safety management, spare no effort to prevent safety risks, timely eliminate potential accidents, and resolutely curb accidents.

In the context of consolidating the safety base and improving the safety management level, the traditional safety supervision mode is moving closer to the intelligent information mode, and people begin to shift their attention from "paying attention to post-processing" to "paying attention to prevention in advance".

Relevant contents of the new work safety law

Production and business operation entities must strengthen the standardization and informatization of work safety, establish a dual prevention mechanism of hierarchical management and control of safety risks and troubleshooting and treatment of hidden dangers, improve the risk prevention and resolution mechanism, improve the level of work safety and ensure work safety.

The production and business operation entities shall establish a hierarchical management and control system for safety risks, take corresponding management and control measures according to the classification of safety risks, establish, improve and implement the investigation and treatment system for hidden dangers of production safety accidents, and take technical and management measures to discover and eliminate hidden dangers of accidents in a timely manner.

In the "prevention in advance", the traditional gas detectors are unstable, easy to be disturbed, and have a high rate of missed and false alarms. In this regard, Hanhai technology group, in cooperation with the Chinese Academy of Sciences, undertook the industrialization of laser absorption spectrum gas detection technology, a major national scientific research achievement. The equipment can realize on-line, high accuracy, calibration free, highly sensitive and reliable detection under the environment of strong acid, strong alkali and various gas interference.

Fixed reflection laser gas telemeter

Hanhai photoelectric fixed reflection laser gas telemetry instrument is composed of laser control unit, spectral analysis unit and optical reflection unit. It adopts laser absorption spectral gas detection technology (TDLAS) to conduct long-distance all-weather online monitoring of gas concentration between laser transceiver and reflection device. Through the networking of multiple devices, the real-time monitoring of the distribution concentration, moving speed and moving direction of different component gases can be realized. It is an ideal choice for monitoring gas leakage in a large open area. It is very suitable for the scenario application of hazardous chemical production enterprises, hazardous chemical storage enterprises and chemical industry parks.

01. Wide detection area

The fixed reflection laser gas telemeter can detect methane at a distance of 1km, and can detect ethylene, acetylene, hydrogen sulfide and other gases at a distance of 200m.

02. Preventive monitoring

Different from the passive waiting of traditional detection mode, it actively monitors the leakage risk points. The response time is only 1 second, which can accurately detect ppm level micro leakage. Truly realize the preventive monitoring of gas leakage.

03. Convenient installation

The laser transmitting end and receiving end are integrated at one end, and the other end is only equipped with a reflecting device, which is convenient to install.

04. Strong anti-interference ability

Compared with traditional detectors, which are easily disturbed by environment, cross gas and other factors, the anti-interference ability is strong. Fingerprint detection, truly achieve zero false alarm.

05. Accurate measurement

The leakage gas concentration is quickly obtained by spectral inversion algorithm, and the sensitivity is up to 1ppm m. Completely eliminate the phenomenon of false positive and false negative.

06. "0" maintenance

The product does not need to be adjusted, which can save operation in the whole life cyclcost.

07. Long service life

The service life of the product is up to 20 years.

08. Detection of gas diversification

Gas detection type: methane, carbon monoxide, hydrogen sulfide, and ethylene Alkene, acetylene and ammonia (more gas detection schemes can be provided according to customer needs)
