Description
This unit of competency involves the skills and knowledge required to manage the inspection and assessment of a structure fire to determine origin and cause. The unit focuses developing and applying a systematic approach to fire investigation in a structured environment.It includes originating structure fire investigations, securing fire scenes and preserving evidence. It also includes the evaluation and examination of fire debris, identifying and recovering evidence relevant to a fire investigation, packaging items of evidence for examination and conducting a thorough analysis of fire behaviour, development and travel as well as gathering evidence to establish fire cause. Application of this unit is relevant to fire investigators who are required to determine the origin and cause of a structure fires.The fire sector is those sections of government departments, statutory authorities or organisations that have responsibility under jurisdictional arrangements for the delivery of firefighting and fire management services.No licensing, legislative or certification requirements apply to this unit at the time of publication.
