3. Point 8 “Evacuation”, 22. 5. 2013 9:50FB informed that Lift in PM 85 not working 10:05FB intervention truck at P8 10:20Technician for Lift maintenance arrives on-site, can give no estimated duration of the reparation FB “evacuates” 30 persons waiting in the PM 85 safe room by the stairs. 3 FB teams are engaged in total 12:00Lift operation back to normal 13th LSC, 21. 6. 2013 Thomas Otto, TE Safety Officer3 FB characterises this intervention as a “mise en sécurité” (safeguarding) With the main evacuation route not working, it may be wise to remove personnel from an area with potential dangers This is a very conservative interpretation of the procedure “Sortie du LHC en cas de maintenance ou panne de l’ascenseur” (2009 ff.)

4. “ Entree ou sortie du LHC en cas de Maintenance ou de Panne de l’Ascenseur ” (presently in work) 2 major cases: Lift not working, normal conditions Personnel may continue working or use another lift at the same Point (2,4,5) or walk to an adjacent point Or use the stairs, after informing FB Lift not working, emergency conditions FB in charge Evacuation pathway depending on availability and location of the danger 13th LSC, 21. 6. 2013 Thomas Otto, TE Safety Officer4

5. Safeguarding of personnel When all lifts adjacent to a sector fail, the personnel will be safeguarded by the Fire Brigade 13th LSC, 21. 6. 2013 Thomas Otto, TE Safety Officer5

6. Accident in LHC sector 1-2 Use of the orbital cutting tool Worker manipulated “manchette” while keeping the finger on the motor command Disrespect of procedure Entrainment of finger Several days of absence 13th LSC, 21. 6. 2013 Thomas Otto, TE Safety Officer6 Doigt d’indexage tenu par la main gauche Porte-outil Sens de déplacement de la manchette

7. Restricted Use of Bump-Caps Obstacles in zones where a helmet is not required. Constrained workstations where a helmet cannot be worn Risk of head injuries 13th LSC, 21. 6. 2013 Thomas Otto, TE Safety Officer7

8. Restricted Use of Bump-Caps 13th LSC, 21. 6. 2013 Thomas Otto, TE Safety Officer8 In areas marked with this or a similar sign a safety helmet according to standard EN 397 must be worn. Only in constrained workspaces, where a safety helmet would be inappropriate, it may be replaced by a bump-cap Not from the CERN stores. To be ordered from external suppliers. Shall conform to standard EN 812
