In October 2022, Anhui Lijian Defense Technology Co., Ltd. signed a contract with the National Safety Production Emergency Rescue Center to officially undertake the research and development task of the safety production emergency rescue technology equipment unveiling project, and develop remote toxic and harmful gas detection equipment for hazardous chemicals to solve the problem of fire, explosion, and poisoning accidents caused by the inability to timely identify the nature of unknown toxic and harmful gas (liquid) leakage in hazardous chemical accident handling, improper or untimely handling, which seriously endangers the lives and property safety of on-site emergency rescue personnel and the people.
As an advanced independent developer of high-performance infrared spectroscopy intelligent detection equipment in China, Anhui Lijian Defense Technology Co., Ltd. has carefully studied the task requirements and development goals, fully utilized its previous technical accumulation and product development and application experience, actively arranged and implemented funds, personnel, and venues, and after careful organization and scientific implementation, completed the research work ahead of schedule in August 2023 and developed remote toxic and harmful gas detection equipment for hazardous chemicals.

On December 5, 2023, the National Work Safety Emergency Rescue Center organized relevant units and experts to conduct an acceptance review of the project in Hefei. A total of 19 people from Tsinghua University, the National Work Safety Emergency Rescue Center Zhoushan Team, the National Work Safety Emergency Rescue Center Crude Oil Field Team, Beijing University of Chemical Technology, Sinopec Safety Engineering Research Institute, the National Work Safety Emergency Rescue Center, the Safety Standard National Mine Product Safety Mark Center, Anhui Lijian Defense Technology Co., Ltd., and the Chinese Academy of Sciences Hefei Institute of Physical Sciences participated in the acceptance. Among them, 5 experts from Tsinghua University and other units formed an acceptance expert group. After on-site inspection and conference review, the project has passed the acceptance inspection.
The acceptance of remote toxic and harmful gas detection equipment for hazardous chemicals marks an advanced new technological means for China's hazardous chemical supervision, accident prevention and early warning, monitoring, and disposal rescue. It helps to quickly improve China's emergency response capabilities for safety production accidents and further meet the practical needs of professional emergency response teams for safety production, thereby enhancing China's hazardous chemical safety management, risk control, and disposal capabilities.
