Beamline Downtime Report R. Klaffky:  Roger reports two faults-- one was an EPS fault. The user was called in at 2:00 a.m. The other was a vacuum glitch on a FE which was reset within five minutes.

March Inspections E. Chang:   Edmund advised of inspections to take place in March 2003 of 431A and 438. Let him know what date and times you want by sending email to: change@aps.anl.gov.

Electrical Safety Lab-Wide Focus Group E. Chang: Edmund solicits your input to content of a new electrical safety course, good or bad, to be shared with the focus group to which he has been newly appointed. Email your comments to him: change@aps.anl.gov. - or phone 2-6714.

Experiment Safety Reviews S. Davey:   Sector safety people will be visited by Bruce Glagola who will be asking them to provide input on the Hazard Control Plan (DOE requirement).

Water Spill Cleanup - P. K. Job:   In reply to inquiries regarding what to do when there is a liquid/water spill, P. K. told the group there were two important things to keep in mind: 1) nothing has been found by HP (no possible activation of deionized water), and 2) you can clean up the spill but if you ask someone else like PFS custodial to clean it, and they ask for a survey to be performed before they will remove it, you must comply with their wish.

Badge Check / Users: S. Strasser: When ANL was graduated from yellow to orange security level, guards had confiscated user badges and actually destroyed about thirty badges. There was confusion as to the proper intensity of color of the blue background with yellow stripes that was being used for User badges. This has now been clarified with ANL Security and they are accepting any shade of blue with yellow stripes.

The security level is currently back to yellow. Expect new criteria for Non-US citizen access to Argonne National Laboratory.

Twelfth Users Meeting (April 29-May 1, 2003) S. Strasser: Susan brought meeting posters and invited the group to take a poster back to the LOMs and encourage users to come to the meeting. Where once this meeting was scheduled to occur every 18 months, it is now moving to an annual meeting. This year especially, student attendance is encouraged. The admission cost has been lowered and cash prize for best student poster is being offered.  Please register through the website at url: http://www.aps.anl.gov/conferences/12um/

Handling Carcinogens in LOM Chemical Fume Hoods B. Stockmeier:   Bruce supplied handouts (see following table and text) and explained fume hood data from a project viewgraph.


20030303 CAT Chat handout

Highly Toxic Materials in LOM Chemical Fume Hoods

ANL policy requires that chemical hoods used for handling carcinogens and other highly toxic materials have a face velocity in the range 120 to 150 feet/minute. As shown below, many APS LOM chemical hoods now operate in this range.

To request adjustment of your LOM hoods flow rate, contact Bruce Stockmeier (bcs@aps.anl.gov or 2-9394).

To request a placards (not required) indicating that highly toxic materials may or may not be handled in an LOM fume hood, contact Edmund Chang (change@aps.anl.gov or 2-6714).

Those handling highly toxic materials in chemical fume hoods should:

Ensure containers and equipment do not interfere with the air flow into the bottom opening at the back of the work surface

Perform work in the back half of the work surface
