Consultant Tomas Rantatalo, Fire safety engineer
Background
1994
• Functional requirements
• Full flexibility
• Alternative solutions
• Unclear safety level
Mission
Start 2006 – In effect, fall 2011
• Functional – Performance-based
• Clear levels
• EU-harmonization
• Cost-efficient fire safety
Conclusions
• More clear level of performance
– Improved hierarchical structure
– FSE methods & criteria
– Mandatory operative requirements
• Dependance on acceptable solutions
– Finding implicit risk levels
• Need of more performance criteria
Hierarchy 2011
Process of fire safety engineering
2. Identify verification need
3. Verification
4. Acceptable risk?
1. Design proposal
Verification methods
• Qualitative
• Scenario based
–Design fires
–Performance criteria
–Evacuation, smoke spread, etc.
• Quantitative
Operative requirements
• Barriers or safety means
–Means of escape
–Prevent fire & smoke spread
–Means of rescue
–Structural integrity
• Robustness
Performance levels
Acceptable solutions
• The foundation
• Building of reference
Performance criteria
• Quantitative
Exceptional buildings
Example, performance levels
Goal Buildings should be design to make it possible to evacuate
Method Acceptable solution Performance criteria
< 30 m to evacuation route 4 scenarios
Design fire 5 MW
Untenable conditions, e.g. 80 C
Important changes
• Risk based occupancies classes
• Cost-benefit analyses
• Sprinkler system in hospitals and nursing homes
• Self-contained smoke alarm in dwellings

Input from …
• Some 15 consultants
• The group of reference
• The Nordic countries
A special thanks to:
• Dr Håkan Frantzich
• Mr Robert Jönsson
• Dr Johan Lundin
• Mr Fredrik Nystedt
• Clear performance level
• A continued flexibility
• Acceptable fire safety for a resonable price
Thank you!
