Prepare for fire and evacuation risk


​How to ensure fire and evacuation safety?

The risk of fire and the need for evacuation safety are constant concerns of a facility manager. Meeting regulatory standards requires the ongoing development of your facilities, systems and organizations to ensure proper management of fire risks and evacuation safety. Investment projects, new materials, products and building methods in particular can lead to the unexpected risk of fire or evacuation safety issues.

VTT's fire and evacuation safety research covers methods of fire and evacuation safety assessment, material performance and risk analysis. Using our cross-disciplinary expertise and computational and experimental methods we can help you in the planning of safety strategies, the design of organisations and systems of different levels, and take-up of new methods and technologies.

Methods for fire and evacuation safety assessments

  • Fire simulation
  • Evacuation simulation
  • Efficiency of fire safety systems
  • Human behaviour
  • Simulation of fire and structures

Material fire safety

  • Atomistic simulation of materials
  • Pyrolysis experiments and modelling
  • Fire safety of composites

Risk analysis

  • Quantitative fire risk analysis
  • Operation time modelling
  • Fire service impact and strategies
