6680 Appendix T3

Lead Use and Storage Areas –

Including Posting Requirements

 

 

1.0          Purpose

 

Jefferson Lab recognizes that an area where lead, and its associated apparatus, is used and stored is considered a hazard issue.  This appendix defines Jefferson Lab’s minimum lead work and storage area requirements, including postings and labels. 

 

2.0          Scope

 

It is recognized that listing the requirements for every activity involving lead at Jefferson Lab would be prohibitive, it is therefore required that Qualified Lead Workers read and follow the requirements/recommendation listed on associated Material Safety Data Sheet(s) for the material and any additional activities outlined on the associated Task Hazard Analysis or Work Control Document. 

 

The process steps for this procedure are performed in coordination with ES&H Manual Chapter 6680 Lead Handling Program.
