Safety E. Chang:   Safety inspections of sectors 20, 19, 18, 17, and 16 have been performed.   The write-ups have been sent out.

Laser inspections by Argonne Area Office will be taking place soon.   If you wish to find out the status, call Ralph Hinterman (ext. 2881) as B. Murdoch will not be available after 3/15/2004).

R. Hislop and E. Chang toured the experimental hall and spoke to many machine shop coordinators about the card key readers.

To receive credit for sector orientation, you can access the link on the ESAF page.

Reminder that the speed limit in and around the ring should not exceed fast walking pace.

BLEPS B. Wesolowski:   The automatic paging for BLEPS faults affecting PS2 is in progress.   All beamlines have been contacted regarding whether they want the service.   The script to accomplish this and the loading of pager information should be complete by next week.

Oxford report and attachments for the restart package included with the minutes.
