ES&H Manual
Chapter 6121 Machine Tools
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.

Purpose
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.


Scope
Jefferson Lab recognizes machine tools as:
  • Non-portable – secured for stability
  • Having a rotational motion, hydraulic, or leverage force

T1 Safe Operation of Machine Tools
As outlined in ES&H Manual Chapter 6121 Appendix T1 Safe Operation of Machine Tools adequate training and knowledge of the safety considerations involved in the operation of machine tools are required at Jefferson Lab. Only personnel who have completed the required training can be authorized by the Machine Shop Manager to operate machine tools.

Jefferson Lab bases its Machine Tool Program on Occupational Safety and Health Administration (OSHA) regulations and American National Standards Institute (ANSI) standards. Operator's Manuals also provide valuable information and are used in preparation of OSPs and training.
Responsibilities:

Management authority may be delegated to a task qualified Jefferson Lab employee at the discretion of the responsible manager.
