What are the principles of chemical treatment and what are the principles of chemical treatment

The three principles of chemical use:

1.Do not touch the medicine with your hands;

2.Do not put your nostrils to the mouth of the container to smell the medicine;

3.Do not taste any medicines.

Handling principle: the remaining drugs in the laboratory should be done"Three noes".

1.The remaining drugs from the experiment cannot be put back into the original bottle;

2.It cannot be discarded at will;

3.Can't take out the lab.

It is the treatment principle of the adsorption process.

1) Activated carbon treatment is more difficult (Song Hood Fat Emulsion Injection) or the adsorption is very large, through the control of raw materials and excipients to meet the requirements of injection (plus bacterial endotoxin), the control of the final product can also be achieved.

2) After experimental research, it is determined that a certain concentration of activated carbon adsorbs the main existence, and other excipients can be dissolved with an appropriate amount of water for injection before decarburization, and then the main drug is added to the decarburized solution to dissolve and then finely filtered. (Generally approved for small-sized injections).

3) If the main drug needs to be decolorized or the concentration and dosage of activated carbon cannot be reduced, the amount of main drug feeding can be appropriately increased according to the adsorption amount to ensure that the content of intermediates and finished products is within the range specified in the quality standards. The increase in the main feeding amount generally does not exceed the upper limit of the content limit in the standard.

Three no's principle: do not hold drugs by hand; Do not put your nostrils close to the mouth of the container to smell the drug; Do not taste the taste of any medicine.

Legal basis: Regulations on the Safety Management of Hazardous Chemicals

Article 1 These Regulations are formulated in order to strengthen the safety management of hazardous chemicals, prevent and reduce accidents involving the destruction of hazardous chemicals, ensure the safety of people's lives and property, and protect the environment.

Article 2 These Regulations shall apply to the safety management of the production, storage, use, operation and transportation of hazardous chemicals. The disposal of discarded hazardous chemicals shall be carried out in accordance with the relevant laws on environmental protection, administrative regulations on fiber destruction and relevant national regulations.

Some metals, such as sodium, are generally stored in kerosene, and when used, they are removed with tweezers, blotted dry with filter paper, and cut into pieces with a knife. The rest cannot be put casually, and must be put back into the original reagent bottle.

Chemically used leftover drugs may be affected by the external environment and deteriorate or contaminate, generally speaking, after taking out, can not be put back, in line with the principle of safety and prevention of environmental pollution, to put into a designated container (generally a waste tank).

However, the dropper bottle can be, or it is an alkali metal, such as sodium, potassium and the like. For example, sodium is generally stored in kerosene, and when used, take it out with tweezers, blot it with filter paper, and cut it into pieces with a knife. The rest can't be put away casually, and must be put back into the original reagent bottle.

The remaining medicines should not be put back into the original bottle, but should be placed in the designated container.

There is a special waste bucket for liquids, and solid drugs can be dissolved in water and poured into the waste bucket, and cannot be put back into the reagent bottle or directly discarded.

Solid drugs can be dissolved in water and poured into waste barrels, and cannot be put back into the reagent bottle or directly discarded.
