Laboratory chemicals and reagent management
A. Storage of chemical reagents and pharmaceuticals
1. The chemical storage room should comply with relevant safety regulations and have safety measures such as fire prevention and explosion protection. The indoors should be dry and well ventilated. The temperature should not exceed 28 °C. The lighting should be explosion-proof.
2. The chemical storage room should be kept by a dedicated person and have strict accounting and management systems.
3. Fire equipment should be provided indoors.
4. Chemicals should be stored according to their class, especially chemical dangerous goods stored separately according to their characteristics.
B. Management of chemical test solution
1. The reagent bottle containing the test solution should be placed in the medicine cabinet, and the reagents and solutions placed on the rack should be protected from light and heat.
2. Do not place heating equipment such as electric furnace near the test bottle.
3. The inner wall of the liquid surface in the test solution bottle condenses water droplets, and shake it evenly before use.
4. After each time you take the test solution, you should change the bottle stopper. Do not open the bottle for a long time.
5. The pipette that draws the test solution should be cleaned and dried beforehand. At the same time, several test solutions contained in the same container are taken to prevent the bottle cap from being mis-contaminated.
6. The test solution that has deteriorated, contaminated or failed should be discarded and reconstituted.
C.Safekeeping of dangerous goods
1. The chemical dangerous drugs used in the experiment must be stored in a special room or cabinet, and should not be mixed with ordinary reagents or randomly placed. They should also be stored separately according to their respective hazardous characteristics.
2. Chemical dangerous drug rooms and cabinets must be managed by special personnel. Managers must have a high sense of responsibility, understand the dangerous characteristics of various chemicals, and have certain protection knowledge.
3. The chemical dangerous goods room should be equipped with corresponding fire-fighting facilities, such as fire extinguishers, etc., and the special personnel should be inspected regularly.
4. Regularly check the packaging, labeling and status of chemical dangerous goods, and check the inventory quantity so that the accounts are consistent.
5. The abandoned waste liquid and waste residue of dangerous drugs in the experiment should be collected in time and properly disposed of, and should not be kept in the laboratory, or even left in the sewer.
6. If there is any problem in the management and use of hazardous reagents, besides taking measures to eliminate them promptly, they must report to the leaders in a timely manner and must not be concealed.
