6680 Appendix T4

Lead Clean-Up, Disposal, and Recycle Procedures



1.0           Purpose


This appendix 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.


2.0           Scope


Clean-up activities that allow lead particulates to become airborne are prohibited at Jefferson Lab. Contact Industrial Hygiene concerning disposal of lead and lead-contaminated material.


NOTE: Dry sweeping, scraping, or compressed air, may cause lead particles to become airborne. Operations, other than those listed within this appendix, are considered to have a Risk Code >2 and require a Work Control Document. 


The process steps for this procedure coordinate with ES&H Manual Chapter 6680 Lead Handling 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            Qualified Lead Worker

·       Abide by clean-up procedures listed below when working with lead.


3.2            Supervisor, Technical Representatives (TR), and Sponsors

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


3.3            Industrial Hygiene

·       Provide regulatory compliant clean-up training, supplies, and equipment (e.g.: wipes, impermeable containers, “Lead-only” HEPA vacuums).


4.0           Process Steps


Unless otherwise stated the Qualified Lead Worker performs the process steps stated below.

4.1.1       Surface Wipe Down


Step 1:          Prior to commencement of work – obtain from Industrial Hygiene:

·       Training

·       Wet-Wipes (also available from the Stockroom)

·       Cleaning agents

·       For solid surfaces, consider the use of "Decon Gel" for cleaning rather than soap/water solution to minimize wastewater generation. Contact Industrial Hygiene for review of decontamination options.


Step 2:          Upon completion of work, use appropriate cleaning supplies and techniques to wipe down the work surface, or in accordance with training. 


Step 3:          Contact ESH&Q for disposal of used cleaning supplies.


4.1.2       Vacuuming 


Step 1:          Prior to commencement of work – obtain from Industrial Hygiene:

·       Training

·       “Lead-only” HEPA vacuum obtained from Industrial Hygiene

·       Impermeable container


Step 2:          Upon completion of work – use “lead-only” HEPA vacuum obtained from Industrial Hygiene to clean the work surface in accordance with training. 


Step 3:          Collect in the impermeable container:

·       All used clean-up material

·       Used work-related PPE

·       Other disposables personal protective measures. See ES&H Manual Chapter 6680 Appendix T2 Lead Handling Personal Protective Equipment (PPE) and Other Related Personal Protective Measures.


Step 4:          Securely close and label the impermeable container


Step 5:          Return “Lead-only” HEPA vacuum and impermeable container to Industrial Hygiene.


4.1.3       Encapsulate


Step 1:          Obtain Decon Gel from Industrial Hygiene


Step 2:          Paint the contained surface with Decon Gel


Step 3:          Allow at least 24 hours to dry


Step 4:          Peel the dried Decon Gel from the surface


Step 5:          Submit waste to ESH&Q for disposal


4.2            Disposal of Other Lead Contaminated Items


Contact Industrial Hygiene for instructions regarding the disposal of lead and lead contaminated material such as:

·       Rinse water used to clean lead parts

·       Used solder mats

·       Debris from machining

·       Spent “lead-only” HEPA filter vacuum bags used in collection of lead dust

·       Protective sheeting and coverings
