Laboratory Safety Operational Specification Dress code 1 Workclothes must be worn when entering the laboratory. 2 Protective devices (such as protective gloves) must be worn for the operation of hazardous substances, volatile organic solvents, specific chemicals or other toxic chemicals and biological samples. 3 In experiments, contact lenses are strictly prohibited (to prevent chemicals from splashing into the eyes and corroding and burning the eyes). 4 Long hair and loose clothes should be properly fixed, and slippers should not be worn in the laboratory. Two Dietary Regulations 1 It is strictly forbidden to eat in the laboratory. 2 Food is forbidden to be stored in laboratory refrigerators or storage cabinets. Relevant Regulations on Storage and Operation of Three Reagents 1 When operating dangerous reagents, we must strictly abide by the operating rules and strictly prohibit changing the experimental process by ourselves. 2 When using reagents, we should first confirm whether the label on the container is the required experimental reagent.Confirm whether the drug is a hazardous substance and whether there is a warning sign. 3 The use of volatile organic solvents, strong acids and alkalis, corrosive reagents, toxic reagents and so on must be operated in the fume hood. 4Organic solvents, solid chemicals, acidic and alkaline compounds should be stored separately. Volatile chemicals should be stored in wellventilated reagent cabinets. 5 Avoid doing dangerous experiments alone in the laboratory. 6Hazardous experiments must be conducted with the approval of the leaders. More than two people can be conducted in the presence. Hazardous experiments are strictly prohibited on holidays and nights. 7 When doing experiments on harmful gases, they must be carried out in the fume hood. 8 When the experiment is carried out (spiral, swing, blow drying, etc.), the mouth of the container is strictly prohibited from facing people. Safety Regulations on Electricity Use 1 Installation and use management of electrical equipment in laboratory must meet the requirements of safe power consumption. Special lines must be used for power consumption of high-power experimental equipment. Sharing with lighting lines is strictly prohibited, and fire due to overload should be avoided. 2 No random wiring is allowed in the laboratory. 3 Switches, sockets, plugs and other devices in laboratory power lines and distribution panels, boards, cabinets and line systems should always be in good working condition. The power of air switches must match the allowable capacity of lines.Indoor lighting fixtures should always be in a stable and usable state. 4 Instruments and equipment in the laboratory must be grounded if they are required to be grounded safely. Circuits should be checked regularly. 5 No open fire is allowed for heating in the laboratory and smoking is strictly prohibited. 6 Do not touch electrical appliances or equipment if you have water or humidity on your hands. 7 The appraisers in the laboratory must master the performance and operation methods of the instruments and equipment in the laboratory and operate in strict accordance with the regulations. 8 Daily duty personnel or those who finally leave the laboratory are responsible for the safety inspection of water, electricity, gas, instruments, doors and windows. 5. Safety Regulations for Pressure Vessels 1 Gas cylinders should be specially designed, and other kinds of gases should not be refitted at will. 2 Cylinders should be kept in a cool, dry place away from heat sources. 3 The cylinder should be handled lightly and steadily, and placed firmly. 4Generally, all kinds of barometers should not be mixed. 5 Oil contamination on oxygen cylinders is strictly prohibited. Pay attention to oil contamination on handles, wrenches or clothes. 6 The gas in the cylinder should not be exhausted to prevent backfilling. 7When opening the valve, stand on the side of the barometer. Do not align your head or body with the cylinder main valve in case the valve or barometer rushes out and hurts. 8 Check the normal pressure gauges of various gas cylinders from time to time. 6. Environmental sanitation and conditions 1 Laboratories should pay attention to environmental hygiene and keep clean. 2 Waste removal and disposal must meet sanitary requirements.Dumping shall be carried out at designated locations, and no dumping or accumulation shall be allowed at will.Biological waste should be collected regul
