Safety is the process of reducing the chance of injury or harm through thoughtful action and, in engineering settings, includes knowledge related to (a) laboratory guidelines and standards, (b) machine and tool safety, and (c) personal protective equipment and attire. This core concept is important to the practice of Material Processing as life is full of many hazards, which can be particularly true in engineering-related environments or facilities where machines and materials are being used by people. Furthermore, engineering professionals apply an understanding of safety principles and guidelines to inform their decisions when developing a design and performing the related operations toward improving their work environment.
