2. MATERIALS: Objective: understanding the behaviour of materials when exposed to fire F.Corsanego 2

3. Materials properties: combustion speed. Furniture, fittings Decorations, panels, etc. (permanent or temporary, ie: associated to celebrations) Construction materials F.Corsanego 3

4. Typical accident chain: A cigarette ignites a sofa A « flashover » may follow a few minutes Its very quick, even if smoke detection raises the alarm Most victims are found in the room at the origin of the fire EDMS No 1082781 SEE template for presentations 4 Exemple: small flame(cigarette) on an upholstered furniture. First cause of fire mortality: Sofa fire flashover Sofa ikea comparison Upholstering foam is also known as « solid gasoline » amongs the fire brigade people High-speed propagation example: upholstered sofa

5. CUT Effect of cuts and damage on sofas Even if a manufact is certified (DIN 4102 - classe B2), surface damages can completely void its performance (ref. CERN Test EDMS 1020319 ) F.Corsanego 5 4 min

6. Trash container fires F.Corsanego 6 Fire test made at Warrington Fire Research Centre Waste bins (video)

7. (Example of price enquiry on google -2010) Avoid large plastic garbage containers Assure frequent removal of garbage and residuals of operations F.Corsanego 7 A steel garbage bin after a fire

8. Real fire accident cases Many dramatic accidents have occurred in public places, essentially due to poor materials choice associated to other aggrievating factors: 4 th Dec 2009 Perm (RU) Lame horse discotheque fire (156 victimSs) 4 th Dec 2009 Perm (RU) Lame horse discotheque fire 20 th Feb. 2003 Station Club Rhode Island US (96 victims) 20 th Feb. 2003 Station Club Rhode Island US F.Corsanego 8

9. The accident dynamic is very often the same: F.Corsanego 9 Ignition for whatever reason Fire spreads quickly on walls and ceiling A «flash-over» (ignition of all materials) ensues in 2-3 minutes

10. Be attentive(and report to HSE) in occasion of installation of new materials F.Corsanego 10

14. Also external decorations and façades shall comply to strict fire propagation requirements

15. Materials properties At CERN all materials containing PVC or other halogens fire retardants are forbidden. EUROCLASSES for construction materials (A à F) (Commission decision (2000/147/CE) of 8th February 2000) Only hard-to ignite no-flashover classes A and B are fully acceptable Class C has limitations D, E are not authorised Class C room fire Euroclass C room test vs Class A F.Corsanego 15

16. Constructions materials, panels, insulation panels, furniture, curtains, etc. If you are asked for advice -> adress the request to HSE Materials have to respond to fire rating classes F.Corsanego 16

17. FERMACELL (~ 10Euro / m²) Also used to create fire walls Installed as normal gypsum board, on light steel rails F.Corsanego 17

18. F.Corsanego 18 Wood in thickness (> 18 mm) is tolerated, but not everywhere. Excluded from public buildings, technical rooms and areas where combustibles can’t be stored)
