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.

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.
