AB Safety Unit

Meeting 04 12 2008:

Present: I.Brunner, G.Roy, S.Hutchins, R.Bonzano, L.Bruno

tour de table:

GR: 898 measurements need more analysis to size problem, fencing needs, doors to building will have local patrol box not in TT20 chain to stop beam, DP523 also, interlocks to be removed from grille. Civil engineering needed to support shielding around 898.

Logic in SPS TZ80 access chain false: Patrol could miss people in tunnel. Beam possible.Proposition to change key to TI8 and volet on patrol box.

LHC no access during warmup no access around point 5, discussion with K.Foraz

Isolde: old accident poorly reported, 9 months absence from work. Risk analysis for Isolde, wooden mezzanine in rad zone noted.

Sector reorganisation: installations and TSOs to different departments, to study implications with other DSOs, aim for a unified safety structure across sector.

TDC2 risk analysis, reliability of crane?

RB: machines on key access

SH: TT20 ventilation shaft radiation: examine virolle suspended on chain?

RGE10 update with flow-charts of CCC procedures.

PGCSPS: last sections to finish, short presentation in LHC Shutdown planning meeting today.

Better Wiki with e-mail from actions.

Risk assessment page for AB safety webpage.

Chamonix Presentation.

Follow-ups updated.
