FCC Week April 2016 Rome FCC collaboration “fire safety” S. La Mendola and M. Plagge HSE/SEE/XP R. Trant TE/HDO 14/04/2016 2

3 ITSF: a time-tested forum for exchanges on safety S. La Mendola HSE/SEE/XP 14/04/2016

4 Fire safety challenges shared by different physics laboratories S. La Mendola HSE/SEE/XP 14/04/2016

5 Why fire safety justifies a common effort? Fire safety objectives for ordinary surface buildings are reached through compliance with prescriptive compulsory rules. Example: R of French labor code prescribes that “The maximum evacuation distance to reach a stair is never longer than 40 m”. For unique infrastructures such as the FCC, fire safety objectives are satisfied by performance-based design. S. La Mendola HSE/SEE/XP 14/04/2016 Smoke propagation simulations Probabilistic assessments Evacuation simulations Fire modelling Structural fire resistance

6 Workshop in Lund, a first confirmed commitment to collaborate S. La Mendola HSE/SEE/XP 14/04/2016

Main topicSub-topic Hazard characterization Burning behavior of commonly present items Fire simulations Oxygen Deficiency Hazard Flammable gases Passive fire protection Active fire protection systems Fire detection Fire extinction Smoke extraction and ventilation Intervention of rescue teams Life safety in underground facilities Evacuation of occupants Fire risk methodologies and tools Collection, analysis and use of statistics RAMS aspects FCC study: a great opportunity to cooperate! 7 Workshop in Lund: collaboration topics S.

8 Current members of the FCC fire collaboration S. La Mendola HSE/SEE/XP 14/04/2016 Jülich Research Centre (DE) joined the collaboration after the workshop in Lund. A CERN PhD student from the university of Wuppertal (DE) is also involved.

9 Fire protection: workshop at CERN It marked a milestone in the collaboration road map; It included the following topics: Day 1 Air management (smoke extraction) in radioactive facilities Intervention strategies of fire brigade teams Fixed extinguishing systems Day 2 Burning behavior of electric cables Computational fire simulations Performance-based structural fire design Evacuation simulations Draft standards for mine safety S.
