Magali Gruwé - Safety and access (II) : Access system for HWC Abstract and layout Abstract: Hardware commissioning using the access system Set the rules for access, different modes Layout: Moving to using the access system What is being done? Status? Procedure to access in “General access mode” in “Restricted access mode” Issues Conclusions Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Moving to using the access system (I) Access points are being configured to “operational mode” (were in “installation mode” up to now): Biometry is active!! To enter, one Needs to have performed the biometric scan in building 55 Needs Either a personal dosimeter (with the biometry attached). To be obtained in building 55. Or a personal token (with the biometry attached). To be obtained in building 55. Note: this is NOT the HWC token as distributed during commissioning of 4-5!! These should all be given back (anyway, they won’t work anymore) Needs to have appropriate access rights: to be asked via EDH LHC-HC access (Or LHC-CR access, but ONLY for cryo operators!) Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Moving to using the access system (II) When cooling down a sector from 300K to 80K: Access points are in “General access mode” but with restricted access list: LHC-CR No CCC intervention to give access When sector is below 80K: Access points are in “General access mode” but with restricted access list: LHC-HC When ready for power commissioning: Access points are in “Restricted access mode”, with restricted access list: LHC-HC Person in CCC necessary for giving access Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Magali Gruwé - Safety and access (II) : Access system for HWC Status Sector 8-1: Access points UJ14 and UA87 in General mode, LHC-HC list, biometry active Other doors closed and “plombage” put on emergency handles Sector 5-6: Access point PM56, UJ63, UP63 in General mode, LHC-HC list, biometry active Sector 7-8: Access point UJ83 in General mode, LHC-CR list, biometry active Sector 6-7: Next on the list. Will be done on March 10th. Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Magali Gruwé - Safety and access (II) : Access system for HWC Note A power commissioning sector is different from an access system sector!!!! Power commissioning sector: Is one eighth of the ring Contains more than one access system sector Possibly more than one access points (PADs) Access system sector: Belongs to a zone, which belongs to an LHC point (1 to 8) Is related to an access point (PAD) The mode of a sector is the mode of the zone it belongs to And the mode of a zone is defined by the access point A sector is patrolled independently from the other sectors Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

General access mode (I) In order to enter the zone, a person should: Be on the LHC-CR or LHC-HC list (depending on which is active) Badge with the personal dosimeter or the personal token Enter the PAD and perform biometric scan Exit on the other side In order to exit the zone, the person should: Enter the PAD Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

General access mode (II) Entering procedure does not require CCC intervention. In CCC there is a way to know: How many people are in a zone Who is in a zone (name) If a door has been forced open: An icon on the console shows the door which is forced: Even if the door is closed after the passage, the icon still shows the door has been forced Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Restricted access mode (I) In order to enter the zone, a person should: Be on the LHC-HC (or LHC-CR) list Have a personal dosimeter or a personal token Go to the access point of the zone Badge with the personal dosimeter or the personal token Call the CCC by interphone on access point and Explain the reason for the intervention Explain where exactly the intervention will take place Give estimate of duration of intervention Take the access key provided by the key distributor (when/if released by operator in CCC) Use the released access key to unlock the PAD Enter the PAD and perform biometric scan Exit on the other side Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Restricted access mode (II) In order to exit the zone, the person should: Badge with the personal dosimeter or the personal token Press the unlock button Enter the PAD Exit on the other side Put the access key back in the key distributor (which will open itself automatically) Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Restricted access mode (III) In CCC: When receiving an access request, the EIC/operator should : Ask The reason for the intervention Where exactly the intervention will take place How long the intervention is foreseen to last Inform The person about the ongoing tests/dangers Decide if intervention can occur or not Depending on status of powering (which test is ongoing) Type and location of intervention (See next talk) In case intervention can occur: Release an access key Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Restricted access mode (IV) In CCC: Possible to know: How many people are in a zone Who is in a zone (name) If a door has been forced open An icon on the console shows the door which is forced: Even if the door is closed after the passage, the icon still shows the door has been forced Search signal of the sector is not valid anymore: a patrol has to be performed Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Restricted access mode (V) Rules: Before powering circuits in an octant: Access points of the area should be in “restricted access mode” (yellow on access touch screen) (See next slide) Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Magali Gruwé - Safety and access (II) : Access system for HWC Access touch screen Restricted access mode General mode Some veto is applied (not in access mode) Being patrolled Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Restricted access mode (VI) Rules: Before powering circuits in an octant: Access points of the area should be in “restricted access mode” (yellow on access touch screen) Area has to be patrolled: Search signal has to be valid for all involved sectors If not the case: no powering should take place till patrol has been conducted (See next slide) Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Magali Gruwé - Safety and access (II) : Access system for HWC Access console Missing key No missing key Search signal is valid Patrol box not armed Search signal is not valid Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Magali Gruwé - Safety and access (II) : Access system for HWC Issues (I) Access system will NOT replace the war map: Possible to know who has entered through which access point, but NOT possible to know where exactly the person went, where exactly the person is working, what the person is doing Thus: In CCC: When given access (releasing key): Ask about the intervention and update the war map When starting tests: call the people in the tunnel to confirm their position, warn them about the tests to be started In tunnel: Stick to the foreseen intervention: no initiatives without checking with CCC Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Magali Gruwé - Safety and access (II) : Access system for HWC Issues (II) Access system is NOT interlocked with magnets (except very few specific cases): If a door is forced: powering of circuits can (technically) continue. No interlock to stop the tests! Thus: In CCC: When given access (releasing key): Ask about the intervention and update the war map When starting tests: call the people in the tunnel to confirm their position, warn them about the tests to be started Before starting tests: check that “search” signal of all relevant sectors is still active (which means patrol is still valid). In tunnel: Never ever force open a door: do not use emergency handles (except in case of real emergency of course)!!! Always use the access points (therefore CCC will be informed) and possibly the “unlock” buttons next to sector doors Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Magali Gruwé - Safety and access (II) : Access system for HWC To open a door Do not use this: Use this instead: If button not green or if it doesn’t work: this means you should not enter! Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Magali Gruwé - Safety and access (II) : Access system for HWC Issues (III) Who will give access? During shifts: HWC/OP EIC or operators In case of need, over night or during weekend: TI operators Do people know how to give access? Not all (yet)… Training foreseen: Lecture on access system on March 12th Hands-on sessions on March 12th, March 13th or March 14th At least one console has to be RESERVED for ACCESS!!!! No use for ANY other purpose allowed No test, no PM analysis work, no QPS monitoring, etc… No installation of other software and/or documents Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Magali Gruwé - Safety and access (II) : Access system for HWC Issues (IV) Time to take care of access requests: Access in restricted access mode requires intervention in CCC: Either EIC or operator (in consultation with EIC) has to take the time to deal with access requests Time for patrolling: Before starting power commissioning Whenever a door is forced open: No means to know who has entered a sector If door is forced open, it remains open till emergency handle has been properly rearmed: no means to know who might be entering in the mean time. Thus: Patrol is required. Takes time and man-power. But as powering should be stopped till patrol is done: plenty of people available in the CCC to go and patrol the area… Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008

Magali Gruwé - Safety and access (II) : Access system for HWC Patrol’s issues Patrol procedure: Patrol circuits defined in edms documents Patrol procedure (responsibilities, equipment, etc…) being worked on. Patrol team: Patrol leader: Who? To be defined. Being worked on. Other patrol members: Who? To be defined. Should be a pool of people whom EIC can call whenever needed. Being worked on. Training: Patrol leaders and patrol members will have to be trained before powering starts! To be organized. General patrol issues will be dealt with in BFSP meeting this afternoon.

Magali Gruwé - Safety and access (II) : Access system for HWC Conclusions Plus: We will know who is IN When starting a test: can call each person who is IN to ask where he/she is, what he/she is doing, and to warn about forthcoming test Minus: Time to give access via console (EIC or operator, in consultation with EIC) Doesn’t replace the war map: once in tunnel, where does the person go? Whenever a door is forced: patrol required Powering of magnet is NOT interlocked: still need discipline and appropriate procedures Magali Gruwé - Safety and access (II) : Access system for HWC 2/28/2008
