If chemical waste is discharged directly without disposal or improper disposal, it will seriously endanger the life and health of the experimenters and the safety of the environment. Obviously, safety management can not be ignored. You understand the relevant information.
Improving the Safety Management System of Waste
实验室化学废弃物，具有成分复杂多变，无固定排污量及聚集排污点，难以停止大范围聚集处置等特性，处置难度很大，容不得半点马虎与造假，必需要有强迫性的处置规则，包括法令法规、规范及 技术实现 手册等规则，实在增强对实验室药品和样品的平安监管，指导各实验室按照化学性质树立处置办法，完成实验室废弃物的无害化处置，打造Green化学实验室，维护生态环境。
Laboratory chemical wastes have the characteristics of complex and changeable composition, no fixed discharge and centralized discharge points, and it is difficult to stop large-scale centralized disposal. It is very difficult to dispose of them. It is not allowed to be sloppy and fraudulent. It is necessary to have compulsory disposal rules, including laws and regulations, norms and technical manuals, so as to enhance the safety supervision of laboratory drugs and samples. According to the chemical nature, laboratories set up disposal methods, complete the harmless disposal of laboratory waste, build green chemical laboratories, and maintain the ecological environment.
Inventory Management of Waste
Every laboratory should set up a close list of wastes, solid, liquid and gas, including unused reagents and their packaging, by-products and leaks in the experimental process, and liquidations after the experiment, and stop classifying chemicals and sample wastes according to their physical and chemical characteristics, such as toxicity, radioactivity, corrosiveness, acidity and alkalinity, flammability, explosiveness and oxidation. Sex, resilience and pollution.
For each type of waste, the source, main composition and properties of the compounds should be indicated, indicating the risk of toxic gases, heating, splashing and explosion. In order to avoid secondary pollution, it is necessary to select harmless or easy-to-dispose drugs or methods as far as possible. Detailed treatment measures are indicated, such as treating cyanide-containing wastewater with bleaching powder, treating certain acid liquids with quicklime, and treating waste alkali liquor with waste acid liquor. If it cannot be handled properly, it must be labeled as a legitimate professional disposal agency.
When disposing of laboratory waste, we should set up a strict disposal account, stop meticulous recording of the disposer, disposal quantity, disposal method, disposal time and other related information, double review, regular inspection and long-term archiving.
Classification and Collection of Waste
Laboratory waste should be classified and collected according to different properties, incompatible experimental waste should be collected and stored separately, and should be stopped by the inspectors according to the classification rules and collected separately in the storage containers designated by the laboratory. For flammable, explosive, highly toxic and other chemicals in use and after the use of waste residues, waste liquids, experimental operators should be timely and properly disposed of, classified and poured into designated containers, strictly forbidden to be left in disorder. The culture medium, specimens and bacteria storage solution, disposable medical supplies and disposable instruments after the experiment should be strictly stopped and placed in designated containers according to the rules.
