This is a single-wide mobile trailer that has been converted to simulate a normal residential structure and areas of restricted passage. The trailer is separated into three distinct rooms. Two of the rooms are built with two levels. The bottom level is divided into 1 X 1 metre cubicles with sliding doors. This allows the instructors to change the floor plan to prevent repetition. Inside this prop, firefighters are challenged with all kinds of obstacles such as ropes draped across hallways, floor hatches and interior stairs as they quest in their search and rescues in a smoke-filled environment.
