PUAFIR607A
Apply electrical_electronic knowledge to fire investigations

This unit covers the competency required to inspect and assess a fire scene to determine whether the origin and possible cause of fire is related to the presence of electrical installations and appliances, in accordance with agency procedures.It includes identifying sources of evidence, collecting and documenting that evidence in preparation for analysis, and developing findings and conclusions. No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Application

Application of this unit applies to fire investigators who are required to assess a fire scene and to identify whether the presence of an electrical circuit, equipment or appliance may have contributed to the cause of fire.
