Abstract
Abstract A mobile fire safety training facility which simulates a residential structure and has reduced scale rooms and exterior for appeal to children. A two level structure mounted on a conventional flat bed trailer includes conventional house windows and doors for instruction on escape methods, a non-toxic smoke generator, operating smoke alarms and a functioning telephone system for instruction on emergency telephone use. The reduced overall height of the structure and a truss roof structure permit highway transportation, and an on-board control room with full view of the entire interior assures the safety of the children using the facility.
