Preface. This document has been prepared within Task 3 Escape route doors of Project 4.3 Fire safety measures for dwellings within FRIC - Fire Research and Innovation Centre. It is a continuation of the first part of the project, which resulted in the report Fire performance of escape route doors in cultural heritage buildings A state-of-the-art review [9].
