1.5 RISK ASSESSMENT AND HAZARD MITIGATION
Machine Tools are specifically designed to perform precise material-removal oper-
ations.
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 to be 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.
In contrast, Portable Machine Tools are designed for on-site machining applica-
tions. They typically attach directly to the workpiece itself, or to an adjacent struc-
ture, and achieve their rigidity from the structure to which it is attached. The
design intent is that the Portable Machine Tool and the structure to which it is
attached become one complete machine during the material-removal process.
To achieve the intended results and to promote safety, the operator must under-
stand 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 Porta-
ble Machine Tool and the workpiece as a whole.
