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.

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.
