Abstract

This paper describes an investigation of the effect of inlet openings in a multi-story underground building or station. Smoke filling tests were carried out in a model test rig consisting of a fire compartment and a three-story model structure with horizontal openings between each floor. A 0.25 m x 0.25 m kerosene pool fire was arranged in the fire compartment. The fire compartment and the lowest floor of the three-story model building were connected with a door opening. A shaft was arranged at the top of the fire compartment to make it possible to investigate the spread of smoke from the fire compartment into the three-story building, i.e., the inlet air was drawn down through the horizontal openings at each floor level and into the fire compartment. The height of the shaft was varied, as was the size of the horizontal openings and the door opening. The aim of the work is to determine the critical conditions needed to prevent the smoke from spreading from the fire compartment to the first floor compartment.
