Fire Safety Engineering 4 (CIVE10028)
Normal Year Taken
Delivery Session Year
This course provides a training in engineering approaches to applied problems. The student is introduced to the principles of design for the fire safety engineering of various infrastructures, with an emphasis in the built environment. A variety of different aspects of design are discussed (including: flammability, detection & alarm, smoke management, fire suppression, fire resistance, egress, etc.), with particular attention to systems of classification and design applications. The course distinguishes 'prescriptive' and 'performance-based' approaches to design, with an emphasis on understanding the philosophy of design guidance; references are made to more advanced methods and opportunities to use fire science knowledge and engineering analysis approaches, as well as the interface with structural engineering. The overall aim is to build confidence in tackling simple fire safety engineering design with due consideration to any limitations, uncertainties or conservatisms which may be present.
