How to manage the chemical supply drugs?

The supply management of chemical drugs mainly includes the following aspects:
Procurement Management:
Application and approval: Each department shall submit a reagent purchase application based on experimental requirements, including detailed information such as reagent name, specifications, quantity, etc., and submit it to the procurement department.
Market research and supplier selection: The procurement department conducts market research, selects suppliers through inquiry, comparison of quotations, and signs formal procurement contracts to confirm specific details such as delivery time and location.
Acceptance and delivery: The reagents need to be inspected by designated personnel and the inspection results should be recorded in the inspection report. After completing the purchase process, the reagents and related documents should be delivered to the application department.
Storage management:
Inventory management: Each department needs to establish a reagent inventory ledger, recording the name, specifications, quantity, purchase date, etc. of the reagents.
Storage environment: Reagents need to be stored in dedicated reagent cabinets, which should be clearly labeled and equipped with safety facilities such as fire prevention, explosion prevention, and ventilation. Reagents of different properties should be stored separately to avoid mixing and causing chemical reactions.
Safety inspection: The reagent cabinet should be regularly inspected to ensure that the environment inside the cabinet is dry and the temperature is appropriate, and to prevent harmful gas leakage.
Usage management:
Safe operation: Before using the reagent, it is necessary to carefully read the safety instructions of the reagent, familiarize oneself with its properties, hazardous characteristics, and handling methods. When using reagents, protective equipment such as laboratory gloves, goggles, lab coats, etc. should be worn.
Waste disposal: Used waste should be classified and stored, and disposed of in accordance with company regulations. If an accident occurs during the experiment, it should be reported in a timely manner, corresponding emergency measures should be taken, and relevant personnel should be notified.
Training and Management:
Training: Regularly organize training on the use and management of chemical reagents to enhance employees' safety awareness and operating standards.
Dedicated person in charge: Each department needs to designate a dedicated person to manage and monitor reagent inventory, regularly conduct inventory checks on reagents, and ensure that inventory matches the ledger.
Expired processing: Before the reagent is about to expire, relevant departments should be notified in advance for processing.
