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

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

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

Fire prevention in Luxembourg Guideline : Stability : - Conform to Eurocodes pt. 1. 2. National annexes Stability even while cooling down and after cooling down slide 7

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

Fire prevention in Luxembourg 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 slide 7

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

Fire prevention in Luxembourg 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 slide 9
