Safety Documentation

Users are required to have Jefferson Lab safety training, including EH&S and radiation worker training, which are regularly scheduled, and ODH training / testing, which is given by the User Liaison Office.

Please read the following three documents, and confirm by sending an email to Joe Mitchell: mitchell@jlab.org.

COO: Conduct Of Operations - postscript
ESAD: Experimental Safety Assessment - postscript
Hall A ESAD - postscript

There are in addition several more documents to read, and the Hall A safety walkthrough.

A copy of the Hall A 1999 RWP is in the counting house. Please read and sign it if you have not already done so.
Copies of the 89-019/99-008 and 94-012 RSADs (Radiological Safety Assessment Documents) will be in the counting house. Please read them.
Hall A safety walkthrough instructions
Noone should operate the radiator without training from Dave Meekins / Ron Gilman. Hall A radiator documentation (revised 2001) is available for those interested.

Getting started...

How to join the e89019 and/or e94012 experiment email list - emails will in the future be sent to both of these mailing lists, you only need to sign up for one.
