1.5 Risk Assessment and Hazard Mitigation
Machine Tools are specifically designed to perform precise material-removal
operations.
Stationary Machine Tools include lathes and milling machines and are typically
found in a machine shop. They are mounted in a fixed location during operation and
are considered a complete, self-contained machine. Stationary Machine Tools
achieve the rigidity needed to accomplish material-removal operations from the
structure that is an integral part of the machine tool.
Portable Machine Tools are designed for on-site machining applications. They
typically attach directly to the workpiece itself, or to an adjacent structure, and
achieve their rigidity from the structure to which it is attached. The design intent is
that the Portable Machine Tool and the structure attached to it become one complete
machine during the material-removal process.
To achieve the intended results and to promote safety, the operator must understand
and follow the design intent, set-up, and operation practices that are unique to
Portable Machine Tools.
The operator must perform an overall review and on-site risk assessment of the
intended application. Due to the unique nature of portable machining applications,
identifying one or more hazards that must be addressed is typical.
When performing the on-site risk assessment, it is important to consider the Portable
Machine Tool and the workpiece as a whole.
