On May 3, 2024, an explosion occurred in the pentafluoroiodoethane synthesis reactor at Sichuan Xi'ai Fluorine Technology Company, resulting in the death of three people. Subsequently, on May 4 and May 5, fires broke out consecutively at Mengrong Fine Materials Company in Baotou, Inner Mongolia, and Hongzi New Energy Technology Company in Jiangsu. The specific causes of these incidents are under investigation.

Just days before, on April 30, the Ministry of Emergency Management had issued a notice announcing the launch of the 2024 National "Safe Production Month" campaign. The notice emphasized the need to thoroughly promote and implement the important statements of General Secretary Xi Jinping on work safety.

The Ministry of Emergency Management issued safety reminders twice before and during the "May Day" holiday, clearly outlining requirements for handling abnormal operating conditions and ensuring safety during inspection and maintenance operations. However, the consecutive occurrence of three chemical accidents has exposed issues such as inadequate attention and implementation in some regions and enterprises. This has also sparked reflections on the importance of technological prevention over manual prevention. By adopting advanced technological means to improve detection efficiency, the installation of fixed reflective laser gas telemetry meters and fixed scanning laser gas telemetry meters in areas such as equipment, tank farms, reactors, compressors, and more, can effectively detect the leakage and spillage of hazardous gases. Due to their wide detection range, long detection distance, and fast response time, these meters provide broader detection coverage, increased safety, simpler design and construction, and cost savings compared to conventional multi-point fixed detectors.

Fixed reflective laser gas telemetry meter

Hanhai Optoelectronics' fixed reflective laser gas telemetry meter features an integrated transceiver design with a detection range of up to 1 kilometer. It boasts a response time of just 1 second, enabling precise detection of trace leaks at the ppm level. This meter truly realizes preventive monitoring of gas leaks. Compared to traditional detectors that are prone to interference from factors such as the environment and cross-gases, it exhibits strong anti-interference capabilities. With fingerprint-based detection, it ensures zero false alarms. The product requires no calibration, saving operational costs throughout its entire lifecycle. It can detect a wide range of gases, including methane, ethylene, acetylene, carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia, and more.

Fixed scanning laser gas telemetry meter

The telemetry meter integrates laser control, spectrum acquisition, and spectrum analysis. It emits a laser beam towards the distant object being monitored, which is then reflected back to the telemetry meter. The telemetry meter analyzes the returned signal to obtain gas concentration data. By rotating in both horizontal and vertical directions, the telemetry meter scans and creates a 360° three-dimensional area similar to a radar, enabling coverage and monitoring of a large space with a detection radius of up to 300 meters. Combining detection data with video images allows managers to "see" the current detection situation, including the location being detected and gas concentration information. Leaks can be discovered and located through scanning. Multiple scanning modes can be set, with the scanning detection path freely customizable. It operates fully automatically, without the need for manual operation. It provides real-time online monitoring of gases such as methane, ethylene, acetylene, and ammonia.
