The hazardous chemicals involved in the laboratory are flammable,explosive,toxic,and harmful,with high safety risks.Once not properly controlled,accidents can easily cause significant casualties and property damage.In order to effectively prevent and resolve the safety risks of hazardous chemicals,a comprehensive safety management system should be established.Safety is crucial in the production and storage of chemicals.In order to respond to emergency situations and protect the safety of employees,intelligent hazardous chemical containers have emerged.Intelligent hazardous chemical containers are specifically designed to store hazardous chemicals and materials to ensure their safety,compliance,and ease of management.

　　The"five double management system"should be implemented,namely:double acceptance,double shipment,double storage,double lock,and double ledger.

　　1.Subscription application

　　To avoid duplicate procurement and backlog of reagents,it is necessary to check if there is still any surplus in the reagent storage area before applying for reagents.If laboratory personnel find insufficient reagents,they should promptly notify the person in charge of the reagent application.

　　2.Warehousing

　　At least two highly toxic and dangerous goods administrators shall inspect and register the type,quantity,packaging,danger signs,arrival time,etc.of highly toxic reagents and store them in a dedicated reagent cabinet.

　　The specialized reagent cabinet should be equipped with corresponding fire-fighting facilities,set up obvious signs,and ensure smooth communication;The storage of hazardous chemicals must be isolated,separated,and stored according to performance zones,classifications,and warehouses.Various types of hazardous chemicals with conflicting chemical properties or different fire extinguishing methods are not allowed to be mixed for storage.

　　3.Using

　　When coming into contact with highly toxic and dangerous goods,necessary protective equipment must be worn,and a strict system of two people receiving and sending and two people keeping must be implemented.The administrator should regularly verify the collection status and report any theft,loss,or misuse to the responsible person immediately.

　　Note:Highly toxic and dangerous goods administrators must be politically reliable,have a strong sense of responsibility,and have a certain level of professional knowledge.

　　4.Hazardous waste disposal

　　Strict control of waste should follow the principles of differential treatment,classified disposal,centralized disposal,and harmless disposal.The residue and waste liquid of the reactants after the experiment should not be casually poured out,but should be poured into the container.Especially some flammable,highly corrosive,and toxic hazardous materials(such as concentrated acids,organic solvents,etc.)must be properly treated before being poured into the waste liquid tank.They must not be used for other purposes or discarded without authorization,and relevant records must be kept.

　　The intelligent hazardous chemicals cabinet is used as the carrier to combine the software and hardware capabilities to realize the full life cycle management of hazardous chemicals from the docking of procurement information,label printing,coding and warehousing,application and approval,requisition and return,and reagent scrapping,and to visualize and trace all operation behaviors and operation Data and information visualization.
