Safety - E. Chang: Elroy reported on the following areas of safety:

  • Two OSHA team leaders will be here on a scoping visit (either ANL and/or APS) on June 16-17, 2003.

  • Memo dated May 6, 2003, Carol Scott to Distribution, subject "Update on OSHA Visit, May 6"

  • Safety Inspection Reports documentation of corrective actions should be filled in and returned to E. Chang, bldg. 401.

  • Machine Shop Training - Elroy is in communication with a professor of manufacturing technology from the College of DuPage to provide basic machine shop training. This training will be offered to the Machine Shop coordinators.

  • SECON 1 conditions preclude CAT Directors should now look in their areas at any equipment or supplies they have on-hand, provide instructions on shutdown and startup/recovery, etc. in case of a SECON 1 situation. A list of "essential personnel" is being generated at the present time.

  • Compressed Gas EQO chooses a topic for lab-wide discussion. We have uncovered at least three areas in which a problem could occur with regard to unsafe gas storage. A discussion began on whether gas cylinders needed to be stored separately as storage space is becoming sparse. It was agreed that CATs want to keep their own cylinders in their shed, do not want to share sheds but need larer storage sheds.

ESAF B. Glagola: Were keeping up with the recommendations and revisions for the on-line forms. If there are further requests, please direct them to Bruce Glagola, ext. 9797.

The next CAT Chat will take place on Monday, June 9th at 3:00 p.m. in building 401, conference room A1100.
