When using ether, first check whether there is peroxide. The method is as follows: put 10 ml ether in a test tube, add 1 ml newly prepared 10% potassium iodide solution, shake well and let stand for one minute. If the ether layer is yellow, you can't use this ether. Intransitive verb General operating procedures for hazardous chemicals 1. When preparing dilute sulfuric acid, it must be carried out in heat-resistant containers such as beakers and conical bottles, and concentrated sulfuric acid must be slowly added to water. When preparing aqua regia, nitric acid should be slowly injected into hydrochloric acid and stirred at any time with a glass rod. Reverse operation is not allowed. 2. All reagent bottle should be labeled with toxic drugs. 3. The dissolution of heating products such as sodium hydroxide and potassium hydroxide must be carried out in a heat-resistant container. 4, it is forbidden to reagent entrance. If you need to identify the reagent with your nose, put reagent bottle aside, stir it gently with your hands and smell it slightly. Do not approach the bottle mouth with your nose. The glass tube (rod) is broken, so a small groove must be made in the broken place with a steel shovel, and then the cloth is broken. When in use, the fracture surface should be smooth. When the glass tube (rod) is inserted into the rubber tube or rubber plug, a cloth pad should be inserted to prevent it from breaking and hurting hands. 6, it is forbidden to tableware and utensils mixed together or misappropriate each other. 7, explosive operation, shall not be carried out on people. Don't point the pot at people to avoid possible injuries in advance. Wear protective glasses or set protective baffles when necessary. 8, all toxic gas operations, must be carried out in the fume hood. When the ventilation device fails, it is forbidden to operate. 9. All solid insolubles and concentrated acids are strictly forbidden to be poured into the sink to prevent blockage and corrosion of the waterway. 10. When flammable materials are on your body or hands, clean them immediately and stay away from open flames. 1 1. When opening a large bottle of medicine, the gypsum must be sawed with a saw. Don't knock it open with anything else to avoid breaking the bottle.

12. The treated concentrated acid and concentrated alkali waste liquid must be discharged before being poured into the sink. All waste liquid, if it contains harmful substances exceeding the safety standards, should be treated first, and it is not allowed to be directly discharged into the sewage system. 13. High-temperature objects (such as hot plates or burnt-out burning pipes) should be placed in places where there will be no fire. 14. When taking off boiling water or solution, gently shake it with a beaker clamp before taking it off for use, so as to avoid sudden boiling and splashing when using it. 15, when using alcohol lamps and gas lamps, pay attention to colorless flame burns. Seven, laboratory safety operation procedures 1. 1, staff must wear clean work clothes during working hours. 1.2. All drugs, standard samples and solutions should be labeled. Never put anything that does not conform to the label into the container. 1.3. It is forbidden to use laboratory utensils to hold food, do not use teacups and tableware to hold medicines, and do not use beakers as tea sets. 1.4, toxic, corrosive, flammable and explosive articles should be properly kept, and a large number of them are not allowed to be stored in the laboratory. Should storage and use regulations be observed? Regulations on the safety management of hazardous chemicals? . 1.5. When diluting concentrated sulfuric acid, it must be carried out in a hard and heat-resistant beaker or conical flask. Concentrated sulfuric acid can only be slowly injected into water while stirring. When the temperature is too high, it should be cooled before continuing. It is forbidden to pour water into sulfuric acid. 1.6. Before opening the volatile liquid reagent, put reagent bottle in tap water and cool it for several minutes. When opening the bottle, don't point it at people. It's better to do it in a ventilated kitchen. 1.7, flammable solvent heating, must be carried out in a water bath or sand bath. 1.8. The containers containing highly corrosive, flammable, toxic or flammable items shall be cleaned by the operators themselves. 1.9. When moving and opening a large bottle of liquid medicine, the bottle should not be placed directly on the concrete floor. It is best to use blankets or straw mats. If it is packaged with gypsum, it can be opened after being softened with water. It is forbidden to slam and knock to prevent it from being broken. 1. 10. When taking off the boiling solution, shake it with a bottle clamp to avoid spilling and hurting people. 1. 1 1, glass rod, glass tube, thermometer, etc. When inserting or pulling out the hose, cotton cloth should be padded, and it is not allowed to be forcibly inserted or pulled out, so as not to break and stab people. 1. 12. Open the high-pressure gas cylinder slowly, and don't point the bottle at people. 1. 13. When toxic and corrosive gases such as HCN, NO2, H2S, SO2 and NH3 are released during drug preparation or inspection, it should be carried out in a ventilated kitchen. 1. 14, electricity consumption shall comply with safety regulations.
