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. An Operational Safety Procedure (OSP) is written for each machine tool and read by machine operators prior to use.


Purpose
This chapter provides guidance to help ensure the safe operation of the machine tools used at Jefferson Lab.

Jefferson Lab recognizes machine tools as:
  • Being non-portable - secured for stability.
  • Having a rotational motion, hydraulic, or leverage force.


Scope
This document and ES&H Manual Chapter 6121 Appendix T1 Safe Operation of Machine Tools define Jefferson Lab's safety requirements for the use of machine tools.

Technical Appendices:

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:

Note: Management authority may be delegated at the discretion of the responsible manager.

Everyone at Jefferson Lab
  • Avoid unauthorized entry into machine tool work areas. If you must enter maintain a safe distance from the tools.
  • Wear appropriate eye and hearing protection and clothing. Signs indicating the minimum level of protection and dress code are posted in the machine tool work areas.
