This thesis examines the guarding of the principal metalworking machines employed in the economy. The machines selected for consideration comprise the bulk of metal processing equipment utilized in the basic fabrication and manufacturing processes. It has been intuitively recognized that this equipment has been involved in a significant quantity of industrial accidents by the very nature of the hazards created by their normal use. Consequently, a need to develop some form of guarding or means of operator protection is called for.

In order to examine this question the principal metalworking machines are enumerated, their basic operating characteristics set forth,, and the hazards associated with their use are identified. The principal methods and techniques of guarding against the created hazards are set forth. An examination of the injury record, both frequency and severity, is conducted and the codes and standards governing the construction, care and use of the equipment are presented. Potential sources of aid and assistance in effecting guarding methods are developed and catalogued.

The conditions found and examined are analyzed in a practical light and a specific philosophy adaptable to all aspects of the industry is derived. A program to accomplish the principles and intents of the philosophy is developed and set forth.
