ES&H Manual



6680 Lead Program



Jefferson Lab has determined that working with lead carries an unmitigated Risk Code >2. At a minimum all tasks requiring lead are discussed with the supervisor prior to commencement of work.  An Operational Safety Procedure (OSP) is written for work considered to be Risk Code >2 in accordance with ES&H Manual Chapter 3210 Work Planning, Control, and Authorization Process.

1.0           Purpose

Lead is considered to be a chemical. It is therefore subject to the requirements stated in ES&H Manual Chapter 6610 Chemical Hygiene Program and its associated appendices. This document, and its associated appendices, defines Jefferson Lab’s additional requirements related to lead. 


The use of less harmful materials is the preferred method to mitigate the hazards associated with lead. However, when lead must be used the responsibilities and procedures included within this program are followed. 


This program satisfies applicable federal, state, and local requirements as outlined in ES&H Manual Chapter 2410 Appendix T1 Hazard Issues List.

2.0           Scope

The specific situations where lead exposure is a concern includes:  

·       Lead used during soldering and machining operations.

·       Movement of portable radiation shielding (i.e. bricks, sheeting, and shot bags).

·       Lead oxidation (whitish discoloration on the lead’s surface).

·       Equipment containing lead shielding.


Welding of lead is not authorized at Jefferson Lab and is not included within this program.

3.0           Responsibilities

Note:   Management authority may be delegated to a task-qualified TJNAF employee at the discretion of the responsible manager.


3.1            Lead Requisitioner

·       Implement the requirements of ES&H Manual Chapter 6610 Appendix T2 Chemical Requisitioning and Receiving or ES&H Manual Chapter 3420 Appendix T2 Mitigation Requirements for Hazard Issues involving Service and Construction Procurements, and ES&H Manual Chapter 6680 Appendix T5 Procurement Requirements Related to Lead Work when making procurements involving lead.


3.2            Qualified Lead Worker

·       Complete and maintain appropriate training (SAF 136 Lead Worker Training, or equivalent) and medical monitoring requirements. Lead worker training must be repeated on an annual basis when a workers lead exposure has been determined to be at or above the Action Level of 0.3 mg/m3, this is determined through Industrial Hygiene air monitoring

·       Ensure Pre-Work Planning is adequate. Request a hazard evaluation if lead exposure is considered to be an issue.

·       Abide by minimum protective measures listed in ES&H Manual Chapter 6680 Appendix T2 Lead Personal Protective Equipment (PPE) and Associated Protective Measures when working with lead.

·       Abide by clean-up procedures listed in ES&H Manual Chapter 6680 Appendix T4 Lead Clean-up, Disposal, and Recycle Procedures.

·       Request an equipment/area hazard evaluation from Industrial Hygiene if compliance with requirements is unclear.


3.3            Supervisor, Technical Representatives (TR), and Sponsors

·       Use a less toxic substance whenever practical (i.e. kirksite bricks instead of lead).

·       Assign only Qualified Lead Workers to lead work.

·       Ensure appropriate PPE is available and used during lead handling operations.

·       Ensure appropriate clean-up procedures are incorporated into work plan and performed to prevent lead from becoming airborne.


TRs also:

·       Abide by the requirements of ES&H Manual Chapter 3420 ES&H Aspects of Procurements.

·       Accurately describe the nature of the lead work and any useful information to aid the subcontractor in protecting his or her employees and everyone at Jefferson Lab. 

·       Required an activity hazard analysis that describes the plan for ensuring safety and health during the job. This may include special work methods for lead and any industrial hygiene and/or medical monitoring required by law.

·       Make specific reference to the OSHA lead standards for construction (1926.62) and/or general industry (1910.1025) (as appropriate) within the project specifications for lead-related work (other than lead abatement). 

·       Include requirements to ensure good job-site housekeeping and lead-dust control measures.   


3.4            Industrial Hygiene

·       Perform lead work, equipment, and area hazard evaluation and determine required mitigation including postings.

·       Provide regulatory compliant clean-up training, supplies and equipment (e.g.: bags, vacuums, labels).

4.0           Technical Appendices

4.1            Lead Work Safety Requirements

ES&H Manual Chapter 6680 Appendix T1 Lead Work Requirements provides Jefferson Lab’s minimum requirements when working with lead including: pre-work planning and actual work activities (i.e.: movement of lead bricks, machining, soldering, welding, and lead based paint abatement).


4.2            Personal Protective Equipment and Associated Control Measures

ES&H Manual Chapter 6680 Appendix T2 Lead Handling Personal Protective Equipment (PPE) and Other Related Personal Protective Measures provides information regarding the minimum PPE and associated control measures to be utilized during lead work activities.  Information includes how to:

·       Determine the appropriate protective measures.

·       Determine how to obtain the appropriate protective measures.


4.3            Work and Storage Areas – Including Posting Requirements

Jefferson Lab recognizes that an area where lead, and its associated apparatus, is used and stored is considered a hazard issue.  ES&H Manual Chapter 6680 Appendix T3 Lead Use and Storage Areas including and Posting Requirements defines Jefferson Lab’s minimum lead work and storage area requirements, including posting requirements.  


4.4            Clean-Up, Disposal, and Recycle

ES&H Manual Chapter 6680 Appendix T4 Lead Clean-Up, Disposal, and Recycle Procedures describes the accepted method for lead clean-up; and associated disposal or recycle methods.  Jefferson Lab only authorizes the following clean–up activities:

·       Surface Wipe Down: tools, equipment, floors, soldering or other surface cleaning.

·       Vacuuming: Use “Lead-only” HEPA vacuum obtained from Industrial Hygiene.


4.5            Procurement of Material or Subcontracted Services related to Lead

Procurement of material or equipment containing lead follow the procedure provided in ES&H Manual Chapter ES&H Manual Chapter 6610 Appendix T2 Chemical Requisitioning and Receiving. 


Procurement of subcontracted services involving lead following:

·       The minimum requirements of ES&H Manual Chapter 3420 Appendix T2 Mitigation Requirements for Hazard Issues involving Service and Construction Procurements, and

·       ES&H Manual Chapter 6680 Appendix T5 Procurement Requirements Related to Lead.
