extremity of a powered cableNon respect of lock-out tag-
out rules (consignation)Reinforcement of safety rules for electrical commissioning

2 Jun. 2005Helium release in the LHC
tunnelInjection of helium in a non
commissioned lineLine should be isolated when
not commissioned
n°49UX45
7 Jul. 2005When removing a 45kg
cryogenic safety valve it hit the head of the worker
Broken valveLack of competence of the
firm, activity not planned, no procedure
n°50UX65
22 Aug. 2005When cutting a tube the
operator got his finger caughtFinger tip cut
Machine is not conform, self certification, similar accident
happened before
n°51UX15
7 Sep. 2005Fall when climbing down a
scaffolding ladderScratch on wrist
Scaffolding not conform, no verification, difficult access,
climbing down the ladder the wrong way round
n°52US25
21 Sep. 2005 A plug of the MAFI vehicle
explodedDestruction of plug
Short circuit in the plug and non functioning of the electrical protections
n°53US25
28 Sep. 2005When installing a circuit
breaker the power came backNo damage
Lock-out tag-out procedure not respected.
n°54US45
29 Sep. 2005Strong electrical shock when
touching cable in the false floor
Electrical shockOld LEP cables not protected, not grounded. Circuit breaker
difficult to find
n°55SD18
6 Oct. 2005When pulling cable in PM18,
the cable slipped in the machine and the drum came
off its axleDoor of SD18 damaged
Inadequate machine for the work being performed
n°56Sector 4-5
22 Nov. 2005A finger got caught when
centring manually the EU on the OTU
Finger crushedProcedure not followed, the
correct tool at the work place
Other Accidents Fatal Accident in
RR13,2 fingers cut in
RE62,Fingers between
soldering machine and support,
Fingers squashed by trailer wheel,
Etc.
•45 accidents or incidents were declared in 2005, 14 were followed by an inquiry, and probably many more were not declared.
•Manual handling, falls, incidents or accident of electrical origin, etc.
•Procedures badly applied, changed at the last minute, not followed or non existing.
•Personnel involved: sub-contractors, interim or experts who are over-confident.
Recurrent Problems
•PPSPS not done, or at the last minute, generic, copy-paste, not adapted to the situation
•Works not declared, or continuing beyond what is declared or authorised
•Safety perimeters not respected
•Lack of supervision and preparation
•No smoking and personal protection
Safety coordination procedure
•PGC - contractual document
•Bidders’ conference - rules are presented
•PPSPS - 30 days before start of work with precise and full task description
•Work Package Analysis, experimental zones
•Joint inspection (VIC) - one week before start of work
Work at height
•Accident of the Queen Mary in St. Nazaire: 15 dead (Endel)
•Decree of Sept. 2004 : Scaffolding, platforms, work at height
•Structure calculations, qualification of personnel (erection, control, etc.), training, work with harness, etc.
•New European rules in 2006
Working rules for firms
•Night and Sunday work is forbidden in France and Switzerland
•Derogation only for safety reason (transport, X-rays) or continuity of work (Site guards)
•Strictly forbidden to lend personnel (CERN, company, collaboration, etc.)
Consequences of an accident at SLAC
• Electrical arc when installing a circuit breaker in an electrical cabinet.
• 2nd and 3rd degree burn of a person from a outside sub-contractor.
• Stop of all activities during a month and all accelerators for 6 months.

immediate risk of death or wound which could be invalidating or
mutilating.Example 1: work at height without collective or individual protection.
Example 2: work on a machine or process without protection.
Example 3: use of dangerous substances without adequate protection
Example 4: use of a faulty device

•Note that the Safety Commission, DSO, TSO, etc. are not in the line
Integration of safety
•Schedule, Quality, Safety
•Optimisation of the installation and maintenance at the design level
•Take into account the work environment
•Work not well prepared or difficult = loss of time, quality and risk of an accident.
•ISO 9000, ISO 14000, OSHAS 18000
Reinforced Safety Coordination Team
•3 safety coordinators (Jean Weber, John Etheridge, Emmanuel Paulat)
•3 more since Jan. 2006 (Hervé Buret, Patrick Thévenon, X)
•1 more Safety Engineer starting Mar. 2006(Stefano Fratianni)
Conclusion
•An accident may have catastrophic consequences on the whole project
•The level of safety revels the respect of the schedule, of quality and of the environment
•Everybody shall be involved
•Compression of the planning must be done without compromise on safety
No project is worth the life of somebody
