Purpose
|
NOTE: Machine tools are inherently risky. Jefferson Lab has determined that use of a machine tool carries an unmitigated Risk Code 3. To reduce the risk to an acceptable level an Operational Safety Procedure (OSP) is written for each machine tool and read by machine operators prior to use. |
Jefferson Lab requires that machine
operators be adequately trained and familiar with the safety considerations
involved in the operation of machine tools. Only personnel who have completed
the required training can be authorized by the Machine Shop Manager to operate
machine tools. This chapter provides the training and mitigation requirements to
help ensure the safe operation of Jefferson Lab’s machine tools.
This program satisfies applicable federal, state, and local requirements as outlined in ES&H Manual Chapter 2410 Appendix T1 Hazard Issues List.
