How is the chemical supply managed?

chemical supply management is a standardized system covering the entire chain from procurement, storage, use to disposal, aimed at ensuring safety, preventing abuse, and improving resource utilization efficiency.
1、 Procurement management: strict approval, controllable source
Requirement declaration: The laboratory or user unit shall fill in the procurement application according to actual needs, specifying the drug name, specifications, quantity, use and other information, and shall be reviewed by the responsible person.
Classification approval:
Ordinary chemical reagents are approved internally by the unit;
Dangerous chemicals and easily producible drugs/explosives need to be registered with the public security organs or obtain permits;
The first category of precursor chemicals for drug production must apply for a purchase permit from the provincial public security, while the second and third categories require county-level filing.
Supplier management: Prioritize selecting suppliers with legal qualifications and good reputation, establish records and sign contracts, and clarify quality and safety responsibilities.
2、 Storage management: classified storage, controlled environment
Special location: Set up dedicated storage rooms or cabinets for fire prevention, explosion prevention, ventilation, shading, and temperature control, and store drugs of different properties in separate areas (such as acid and alkali isolation, and separation of oxidants and reducing agents).
Clear labeling: All containers are labeled with information such as product name, concentration, hazard, expiration date, etc; Dangerous goods also need to be labeled with safety labels.
Ledger registration: Establish a dynamic inventory ledger to record the inflow, outflow, and balance status, ensuring that the accounts match the goods, and conduct regular inventory checks.
3、 Usage management: Standardized operation, leaving traces throughout the entire process
Usage registration: The user must sign the "Usage Registration Book", indicating the date, product name, quantity, purpose, etc., accurate to grams or milliliters for valuable or dangerous goods.
Safety training: First time users must receive safety training, master the properties of drugs, protective measures, and emergency response methods, and pass the assessment before they can operate.
Process supervision: During the experimental process, the guiding teacher or management personnel should supervise students to operate in a standardized manner to avoid waste or misuse; Highly toxic substances must be used under surveillance and with dual locks for two people.
4、 Special category management: strict management in accordance with the law to prevent loss
Precursor chemicals: Cash transactions are strictly prohibited, and units must truthfully record transaction information and file it with the public security organs on time; Lost or stolen must be reported immediately.
Highly toxic and high-risk goods: Implement "five pairs" management (double storage, double collection, double use, double lock, double account), and immediately return the remaining part to the safe after use.
5、 Waste disposal: classified recycling, centralized treatment
The remaining drugs and waste liquids after use must be classified and collected, and cannot be dumped at will.
Hazardous waste shall be handed over to qualified units for unified disposal; Reusable drugs should be prioritized for internal adjustment and use within the organization.
