2 Prescriptive guidelines (dating from 2003) : - Third version today Fire prevention in Luxembourg slide 1

3 Prescriptive texts (dating from 2003) : Same content to all Art. 1 - Objectifs et domaine d'application Art. 2. - Définitions Art. 3. - Implantation Art. 4. - Aménagements extérieurs Art. 5. - Construction Art. 6. - Aménagements intérieurs Art. 7. - Compartimentage1 Art. 8. - Evacuation de personnes, issues et dégagements intérieurs Art. 9. - Eclairage Art. 10. - Désenfumage (évacuation de fumée et de chaleur) Art. 11. - Installations techniques Art. 12. - Installations au gaz Art. 13. - Installations électriques Art. 14. - Prévention de panique en cas d'alarme Art. 15. - Moyens de secours et d'intervention Art. 16. - Registre de sécurité Art. 17. - Réception et contrôles ANNEXE I ANNEXE II Fire prevention in Luxembourg slide 1 bis

4 General prescriptions : - lower buildings : < 7 m - 1 level - 2-3 levels - middle rise buildings : 7 < × < 22 m - high-rise buildings : < 22 m - < 30 m - 30 < × < 60 m - 60 < × < 200 m - > 200 m (not yet existing) Fire prevention in Luxembourg slide 2

5 Specific prescriptions : -Office buildings, -Assembly rooms -Underground Parkings -Hotels -Restaurants -Shopping centers -Hospitals and homes for elder people -Residential buidings -Building sites Fire prevention in Luxembourg slide 3

6 Qualitative Analysis (in project) : -Fire load, -Fire risk, -Occupation (quality of persons) (conform to British Standard) Fire prevention in Luxembourg slide 4

7 Quantitative Analysis (in project) : performance-based fire prevention by fire engineer methods Design fire Definition of scenarios Fire prevention in Luxembourg slide 5

8 Performance-based fire prevention (in project) : Three guidelines : -Stability in fire -Smoke exhaust (evacuation of heat and smoke) -Evacuation-simulation of people Fire prevention in Luxembourg slide 6

9 Guideline : Stability : -Conform to Eurocodes pt. 1.2. -National annexes -Stability even while cooling down and after cooling down Fire prevention in Luxembourg slide 7

10 Guideline : Evacuation of heat and smoke -Prescriptive methods conform to EN norms -General statements -Performance-based calculating (quantitative) Fire prevention in Luxembourg slide 7

11 Evacuation of heat and smoke : 4 types -single storey > 3 m -single storey < 3 m (small height) -small spaces > 300 m 2 < x < 600 m 2 in underground) -atrium Fire prevention in Luxembourg slide 7

12 Evacuation of people -Egress time -Egress time compared to smoke evolution and stability -Optimizing architecture in order to reduce egress time -Optimizing number and width of issues Fire prevention in Luxembourg slide 8

13 Procedures for authorization -Proposal of an authorized expert -Control of scenarios, design fire by authorities and control organisations -Control of different parameters by authorities and control organisations -Calculation and simulation by expert -Control of the result by authorities and control organisations Fire prevention in Luxembourg slide 9
