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 Scope 1 Referenced Documents 2 Terminology 3 Significance and Use 4 General 5 Heat Treating 6 Specimen Preparation/Sectioning 7 Specimen Mounting 8 Mechanical Grinding/Polishing 9 Chemical Safety 10 Electrolytic Polishing/Etching 11 Sulfur Printing 12 Laboratory Ventilation/Fume Hoods 13 Chemical Spills 14 Photography 15 X ray/Electron Microscopy 16 Laboratory Ergonomics 17 Disposal of Residues 18 Keywords 19 1.3 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. ====== Significance And Use ====== 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 ) . 5 4.3 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.
