Smoke and heat control for fires in large car parks: Lessons learnt from research?

This paper focuses on car park fire safety, more particularly on fire and smoke (and heat) dynamics. The first part deals with the choice of design fire, based on recent full-scale car fire experiments with modern cars and different set-ups. Different aspects of smoke and heat control (SHC) systems are then discussed from the perspective of smoke (and heat) dynamics. The focus is mainly on the effect of horizontal mechanical ventilation, a popular technique, on the smoke and heat generated by the fire source. Some fundamental differences from (longitudinal) mechanical ventilation in tunnels are described. Possible effects of water (sprinklers, water mist or from a fire brigade intervention), as well as some possible routes for further research, are briefly commented.
