Abstract
The main objective of Test Two was to demonstrate the effectiveness of ventilation
changes and smoke management on the growth of a compartment fire and to display the
potential for these techniques to be incorporated into an automated fire fighting system.
The compartment furniture and sensory equipment was set up in an almost identical
configuration to that of Test One as described in detail in Chapter 2 and in Abecassis
Empis et al. (2007). The windows and doors leading to the fire compartment, and the
front door of the apartment, were fitted with mechanisms enabling remote opening and
closing thus permitting general control over the compartment’s ventilation. With the aid
of live video streams, the ventilation was altered remotely during the fire to allow the
outflow of any smoke accumulated within the compartment; the intention being to
interrupt the positive feedback loop associated with a stratified compartment fire, thus
delaying the fire growth rate and maintaining tenable conditions within the compartment.
A substantial but enforced change to the ventilation conditions from Test One, given the
circumstances, was the placing of a large hole in the wall from the fire compartment to
the adjacent bedroom.
