Part XV: regulatory information
MSDS briefly describes the harm of a chemical to human health and the environment and provides information on how to safely handle, store and use the chemical. As a service provided to users, production enterprises should provide users with safety instructions along with chemical commodities, so that users can understand the relevant hazards of chemicals, take the initiative to protect when using, and play a role in reducing occupational hazards and preventing chemical accidents MSDS can be prepared by the manufacturer according to relevant rules The MSDS evaluation and certification report is prepared in accordance with the legal provisions and requirements of the country where the product is imported. At present, there is no unified international standard for the preparation of chemical evaluation laws. Generally, the internationally accepted versions are the eec/iso version of the European Union and the OSHA and ANSI versions of the United States. Because the legal documents of chemical management and trade in various countries and even states are different, some of them change every month. If the MSDS report provided is incorrect or the information is incomplete, they will face legal liability. Therefore, at present, foreign customers generally require their material suppliers to provide MSDS material safety assessment and certification reports conducted by professional third-party testing institutions, so as to prevent safety accidents and legal liabilities caused by the material suppliers' own MSDS reports that do not comply with the laws and regulations of relevant countries, or the material safety data provided in MSDS reports that are not true.
Regulations Information regulations on the safety management of hazardous chemicals (issued by the State Council on February 17, 1987), rules for the implementation of the regulations on the safety management of hazardous chemicals (HLF  No. 677), regulations on the safe use of chemicals in the workplace ( LBF No. 423), and other regulations have made corresponding provisions for the safe use, production, storage, transportation, loading and unloading of hazardous chemicals; According to the classification and marking of commonly used hazardous chemicals (gb13690-92), this substance is classified as a flammable liquid with flash point in category 3.2.
