The removed reagents cannot be returned to the original reagent bottle, and the reagents should be covered immediately after picking up, and should not be placed in order to avoid wearing them. ⑹ Radioactive chemical reagents When using this type of chemical reagents, be sure to take protective measures according to the method of using the radioactive substance. Pay attention to the hazard labels and drawings of the medicines to see if they are harmful. In the following, the safety performance of chemical reagents is classified, and the precautions in the use of various chemical reagents are introduced separately. ⑵Toxic chemical reagents General chemical reagents are toxic to the human body.
The label can be coated with molten paraffin for protection. Salts are generally classified according to the position of the metal ion in the periodic table, which is also from left to right, and then salt and acid salts: such as sodium salt sodium sulfide, sodium carbonate, sodium silicate, sodium nitrite, sulfuric acid Sodium, sodium thiosulfate, calcium salts, etc. Includes the properties, uses, general safety requirements,
first aid measures, disposal of discarded reagents, and fire protection knowledge for commonly used reagents. (3) When receiving chemical reagents or medicines, confirm whether the name indicated on the container is the required experimental medicine. Alkali is mainly classified according to the group of metal elements in the periodic table: such as sodium hydroxide, potassium hydroxide, magnesium hydroxide, calcium hydroxide and so on. http://www. Such as: acid splashed on the skin should be washed with lye and so on. (4
When Plastic Micro Tubes hazardous reagents such as flammable and explosive, highly toxic, highly corrosive, and strong oxidizing agents, you must apply in advance to report how many collars are used, and prepare them for use at one time. In addition to the above three categories, there are other categories: such as indicators, acid-base indicator reagents, redox indicators, other indicators, stains, etc . Also avoid contact with the human body to avoid burns to the skin. The size of the label should be compatible with the size of the reagent bottle.
