Maintenance B. Wesolowski : Routine maintenance on doors (all doors) will be scheduled by floor coordinators. Lisa Gades will coordinate effort and lists of doors to be serviced. We will work with contractor so not to have any downtime of Tecknit (contractor). See Bill's email which was sent out on Info-net:
Routine Maintenance of Experimental Enclosure Doors
AOD management was advised of problems related to experimental enclosure door problems due to the lack of routine maintenance (i.e., cleaning and lubricating) of these doors and is considering whether to provide such a service. Presently, enclosure door maintenance is the responsibility of the beamlines. This is done by arranging for the service provided by Tecknit through the Floor Coordinators.
The following is put forth for comment and questions:
- AOD would contract Tecknit to perform routine maintenance of enclosure doors.
- All doors would be serviced once annually.
- Door maintenance would be done during the three scheduled accelerator maintenance periods.
- Floor Coordinators would schedule and track the servicing, insuring that beamlines are contacted, work requests and configuration controlled work permits are complete and, conflicts are resolved prior to door maintenance.
NOTE: if any adjustments or part replacements are found necessary, a separate service request would be put in place and the cost would be the responsibility of the beamline.
If AOD management does put this in place, again it would be the beam line's option to accept or reject this service as has been done in the past with other AOD provided services (i.e., chain falls inspections, sling inspections, etc.)
Comments and questions can be addressed to Bill Wesolowski at email@example.com , phone 2-9496, or page 4-9496.
