Appendix T3 Lead Use
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. This appendix defines Jefferson Lab’s minimum lead work and storage area requirements, including postings and labels.
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 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.
Note: Management authority may be delegated to a
task-qualified TJNAF employee at the discretion of the responsible manager.
