|Chapter 6410 Laser Safety Program|
Lasers and associated apparatus create intense concentrations of direct and reflected infrared, visible, and ultraviolet non-ionizing radiation. Jefferson Lab has developed engineering and administrative controls, warnings devices, and documented procedures to control the hazard issues associated with the use of lasers.Scope
This program satisfies applicable requirements as outlined in ES&H Manual Chapter 2410 Appendix T1 Hazard Issues List.
This program pertains to lasers at Jefferson Lab above Class 2. If the laser class you are working with is unclear, contact the Laser Safety Officer for a determination.
Jefferson Lab considers Class 2 and below lasers to be safe and does not require any special considerations. Individuals are to follow department procedures when using these types of lasers.

T1 Laser Operational Safety Procedure
Jefferson Lab has determined that Class 3B and Class 4 laser light poses an unmitigated Risk Code>2; therefore, in accordance with ES&H Manual Chapter 3210 Work Planning, Control, and Authorization Process, a formal work control document is required for each piece of equipment or system, and the area where it is located. ES&H Manual Chapter 6410 Appendix T1 Laser Operational Safety Procedure (LOSP) has been developed to ensure hazard issues are identified through a Task Hazard Analysis, are adequately addressed, and appropriately mitigated before activities involving lasers are approved or commence.
T2 Laser Requisitioning and Purchasing
Jefferson Lab has established requisitioning and purchasing protocols to ensure that only approved lasers and associated equipment are used on, for, and around laser systems. ES&H Manual Chapter 6410 Appendix T2 Laser Requisitioning and Purchasing describes how to requisition these items so that the appropriate approvals are obtained prior to assembly, inspection and/or use of these items.
T3 Laser Personal Protective Equipment (PPE)
Jefferson Lab recognizes that lasers expose workers to certain recognized hazard issues; some of which can be mitigated through the use of appropriate PPE. ES&H Manual Chapter 6410 Appendix T3 Laser Personal Protective Equipment provides information on how to determine the appropriate PPE, and obtain it.
T4 Laser Alignment
Laser alignment is considered inherently risky. Jefferson Lab has determined that this activity carries an unmitigated Risk Code>2. A separate LOSP is written when laser alignment is required. Individuals involved read, sign, and abide by the documents procedures prior to and during work. ES&H Manual Chapter 6410 Appendix T4 Laser Alignment Activities provides the minimum required activities to be performed during laser alignment.
T5 Laser Safety Controls Inspection
Laser safety controls for Class 3 and Class 4 lasers are inspected prior to initial start-up and every six months thereafter for the duration of operations. ES&H Manual Chapter 6410 Appendix T5 Laser Control Inspection - Checklist Instructions provides the minimum process for performing this operation.
T6 Laser Labeling/Posting Requirements
Jefferson Lab recognizes that lasers and their associated apparatus are inherently dangerous. It is therefore required that they, and the designated area, be labeled to provide warning of the potential hazards. ES&H Manual Chapter 6410 Appendix T6 Laser Labeling/Posting Requirements defines Jefferson Lab's labeling and posting requirements for equipment and areas; and how to update, repair, or maintain these labels.
T7 Student Mentor Program
At Jefferson Lab, employees who are considered students by their supervisors and work with lasers of Class 3 or 4 are required to be in a structured mentor program. The LSS, who is responsible for the equipment and/or area, mentors these employees to ensure they develop safe and reliable working skills. ES&H Manual Chapter 6410 Appendix T7 Laser Safety - Student Mentor Responsibilities provides the minimum requirements of these programs.
Management authority may be delegated at the discretion of the responsible manager.
