16. 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.

17. 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

18. 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

19. 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

22. Gravity of faults MANQUEMENT DELIBERE Gravity MANQUEMENT NEGLIGENCE INATTENTION IMPRUDENCE MALADRESSE Sentence

23. Gravity of faults LE DELIT DE MISE EN DANGER DE LA PERSONNE Expose directly somebody to an 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

24. Line of responsibility The line of responsibility IS the hierarchical line Director General Department Leader Group Leader Project Engineer • Note that the Safety Commission, DSO, TSO, etc. are not in the line

25. 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

26. 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)

27. 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

28. No project is worth the life of somebody
