1 Chemical analysts should wear labor protection articles as required. 2. Analytical drugs should be classified and stored, and strong oxidants, low-boiling inflammables and drugs that can have violent interaction should be stored according to the minimum packaging quantity. The drug storehouse shall not be overloaded or mixed. It is forbidden to store a large number of dangerous goods in the analysis room. Reagents and drugs used for analysis must be labeled. 3 analysts should abide by the relevant provisions of national standards when sampling, and pay attention to the relevant safety regulations of the on-site production workshop. 4 compressed gas cylinders should be properly kept and stored separately, and hydrogen should be stored in limited quantities. Do not exceed two bottles in the laboratory, and do not leak. Hydrogen cylinders and oxygen cylinders shall not be mixed. Liquid oxygen should not be dumped indoors, but should be treated outdoors; And abide by the Regulations on Safety Supervision of Gas Cylinders. Liquefied petroleum gas should be properly kept for glass workers to use. 6 Strengthen ventilation to prevent harmful gases in the air from exceeding the standard. Smoking is strictly prohibited in the laboratory. Open flame operation must be approved, and hot work is not allowed without permission. 8 oil bath can't be excessive, electric heater is fixed, and it is not allowed to move casually. Highly toxic products should be analyzed by special personnel and operated according to regulations. If toxic gas is generated during the analysis, it should be analyzed in the poison gas cabinet. 10 highly toxic samples should be sent back to the workshop in time to prevent loss. 1 1 Operators of highly toxic reagents must know the chemical properties of the preparation and wear protective equipment during operation to prevent accidental diffusion and pollution during operation. 12 where highly toxic reagents are used, there must be ventilation equipment. Before operation, turn on the ventilation equipment before work. Continue to ventilate after work, and then turn off the ventilation equipment later. Ventilation equipment is not allowed to work when it fails. 13 highly toxic reagents shall be kept by special personnel, and must be strictly controlled when used, and shall not leave without authorization. After the 14 test, the operator should thoroughly clean and clean the instruments and workplaces that use highly toxic reagents. Unused toxic reagents must be properly placed and clearly marked, and it is forbidden to take the reagents out of the room. 15 drugs must be under the dual responsibility system of two people. Storage and collection must be carried out in accordance with the provisions of drug administration, and the use of drama drugs must be operated by two people. 16 the scientific research and test analysis of new products, new processes, new varieties and new equipment must be reported to the factory and relevant departments for approval before the analysis can be carried out. The toxicity and related safety, physical and chemical properties of raw materials, intermediate products, products and by-products needed for 17 test should be understood when analyzing the test products. In the analysis of 18 test products, it is necessary to improve the detection methods of toxic and harmful substances, safety protection measures and the idea of "three wastes" treatment, and the dramatic drugs and explosives after test and analysis must be collected centrally to prevent accidents. 19 the production analysis of expanded test products can only be carried out after passing the inspection by the security department. When analyzing and sampling the raw materials of inflammable and explosive chemical products, we must operate in strict accordance with the relevant provisions on fire prevention and explosion prevention.
