13.1 Introduction

Machines perform many functions in the workplace that were, at one time, performed by people. The mechanical advantage provided by machines over humans has enabled industries to grow and expand, and ultimately reduce the cost of production and services rendered. Designed to be powerful, quick, and tireless, machines are capable of performing repetitive tasks unachievable by people. Functions are performed daily by countless machines such as cutting, punching, bending, shaping, tempering, assembling, fusing, finishing, packaging, and handling of products and materials in almost all industries. These mechanical advancements have eliminated a number of hazards workers previously were exposed to and have saved many from occupational injury, and death.

However, with all their benefits, machines present certain hazards and risks. Machine‐related injuries make up the highest number of permanent, partial disabilities, and rank third among all industrial accidents.
