Conduct of Operations – Control of Equipment and System Status Video of the Week – Non-Control of Equipment Collider-Accelerator Department 3-15-11 Take 5 for Safety
Equipment and Systems Alignment • Operations personnel (no just MCR) must be aware of the alignment of systems and equipment within their area, whatever the current mode of operation (i.e., startup, shutdown, normal operations, or maintenance) • Alignment checklists must be developed for all modes of operation and incorporated into the appropriate procedures • Examples of checklists include: • AGS Ring Lockout Tagout Checklist • Compressor Room – Initial Valve Configuration List • Compressor Room – Cryogenic Purifier Operation Checklist • RSC Check-off List • ESRC Check-off List • …
ASE Limits Compliance • Accelerators must establish procedures to ensure proper adherence to accelerator safety envelope limits (C-AD OPM 2.5 series of procedures) • These ASE limit requirements s are sometimes expressed as specific conditions (e.g., the ODH fans must be operable) requiring specific response actions (approved alternatives) if the condition is not met • The OC must direct, or be aware of, all approved alternatives taken in response to not meeting the ASE limit requirements • If there are no approved alternative, then the operations must be stopped in a safe and controlled manner • All appropriate C-AD personnel must be informed of ASE limit requirements • All C-AD personnel having responsibility for actions under ASE limits must periodically review the conditions for operation and ensure that the appropriate actions are performed
Equipment Deficiencies • When equipment deficiencies are discovered, the MCR OC and equipment owner must be notified (OPM 2.9 Trouble Reporting System) • The deficiency is documented in a web based system and identified for correction in accordance with the work control system • The deficiency is communicated via the web system to other affected personnel (e.g., System Engineer, Trouble Reporting Committee, MCR Group Leader) • Other methods for communicating deficiencies to affected personnel include caution tags, narrative logs, turnover checklists, round sheets, annotated status boards, etc.
Alarm Status • Reliable, up-to-date information on the status of the accelerators, Siemens, cooling systems, and the cyro plant is essential for safe and reliable operation • Much of this information is transmitted to the MCR OC and operators and the CAS Watch by control panel or local panel meters, gauges, alarms, etc. • Checking the status of indicating devices and alarms is part of routine inspection tours by CAS Watch and system operators
Work Control • During operations periods, all activities that change the status of systems or equipment important to safety, that affect operations, or that change control indications or alarms for the accelerators, must be authorized by the OC • These activities include maintenance, testing, access control system changes, and others
Equipment Post-Maintenance Testing and Return to Service • Before returning equipment to service following maintenance, the equipment must be tested to demonstrate that it is capable of performing its intended function • Testing should verify that the maintenance was performed correctly • Testing should prove that no problems were introduced as a result of the maintenance activities • The C-AD Maintenance Coordinator must approve all testing on new and existing equipment in AGS, Booster and RHIC rings • C-AD knowledgeable engineers, knowledgeable technicians, and FES Group personnel are responsible for ensuring that testing is performed to prove the operability of certain equipment such as high risk magnets, power supplies, etc.
