Users reported similar unusual activity in Sectors 9, 14, and 19ID. C.-Y. will look at the information they will submit to him to further analyze their data.

Users reported that information was not readily available. Some users remained at their station for long periods, refreshing their monitor screens in hope that more detail could be learned.

C.-Y. asked if we post a message, would that be acceptable. The Users who were present today all agreed that that would be helpful and to add a date and time to the message. Additionally, a PA announcement could be added to help the notification process.

Safety W. Wesolowski:  Last week it was reported in order to prepare for SECON 1, conditions preclude CAT Directors look in their areas at any equipment or supplies they have on-hand, provide instructions on shutdown and startup/recovery, etc..  Following is further information regarding that request:

Each beamline must have a SECON-1 shutdown plan. This is a document describing the shutdown sequence that the beamline would like to see implemented in the case of a site evacuation. This plan should be written to address shutdown during off normal hours and during a run period or maintenance period when few personnel are on site. Floor Coordinators on duty can be utilized to aid in beamline shutdown during off normal hours during run periods.

To aide in formulating individual plans, AOD Floor Coordinators are working on a template for a Beamline shutdown plan should SECON 1 be implemented. Once the template has been completed, Floor Coordinators will work with each sector to formulate individual plans.

Bill Wesolowski and Kevin Beyer are working together to compile a template of SECON 1 plans. The deadline for submission of finalized plans is July 1, 2003.

Two OSHA team leaders will be here on a scoping visit (either ANL and/or APS) on June 16-17, 2003. OSHA personnel will look at electrical panel boards as well as check on panel legends. Please remember to remove all obstructions beforehand.

The next CAT Chat will take place on Monday, June 16th at 3:00 p.m. in building 401, conference room A1100.
