TITLE:	ES&H Manual
DOCUMENT ID:	6122 Appendix T4 Hot Work Area Posting Requirements

1.0 Purpose

Jefferson Lab recognizes that hot work is inherently dangerous. It is therefore required that designated areas and associated equipment be labeled to provide warning of potential hazards. This appendix defines Jefferson Lab’s labeling and posting requirements; and how to update, repair, and maintain these labels.

NOTE: When secondary hazards are identified, such as high noise, these postings are supplemental to the Hot Work Area Signage.

2.0 Scope

The process steps for this procedure are performed in coordination with ES&H Manual Chapter 6122 Hot Work (i.e. Welding, Cutting, Brazing, and Grinding) Safety Program.

3.0 Responsibilities

NOTE: Management authority may be delegated to a task qualified Jefferson Lab employee at the discretion of the responsible manager.
