【国外标准】 Standard Guide on Metallographic Laboratory Safety

4.1 This guide is intended as a summary of safety practices in the metallography laboratory. It can be used as a training reference for those new to the field of metallography and as a refresher to those who are experienced.4.2 This guide is not intended to be inclusive of all safety concerns encountered in a metallographic laboratory. Several books that provide safety information are available (1-15).54.3 Before operating any equipment, it is advisable to read and understand the accompanying manuals and to follow any specified safety guidelines.4.4 Safety data sheets (SDS) for chemicals being used in a laboratory should be on file and readily accessible. When working with any chemicals, especially for the first time, one should review the SDS supplied by the manufacturer and follow any safety guidelines suggested. The most current and applicable SDS should be on file for a given product or chemical.1.1 This guide outlines the basic safety guidelines to be used in a metallographic laboratory. Safe working habits are discussed for various tasks performed in a metallographic laboratory.1.2 The sections appear in the following order:  Section 1Referenced Documents 2Terminology 3 4General 5Heat Treating 6Specimen Preparation/Sectioning 7Specimen Mounting 8Mechanical Grinding/Polishing 9Chemical Safety 10Electrolytic Polishing/Etching 11Sulfur Printing 12Laboratory Ventilation/Fume Hoods 13Chemical Spills 14Photography 15X ray/Electron Microscopy 16Laboratory Ergonomics 17Disposal of Residues 18Keywords 191.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
