Qualification -
Unit of Competency PUAFIR604A - Determine origin and cause of structure fire
Description This unit covers the competency required to manage the inspection and assessment of a structure fire to determine the origin and the cause.It includes the excavation and examination of fire debris, identifying and recovering evidence relevant to the fire investigation, packaging items of evidence for examination and conducting a thorough analysis of fire behaviour, development and travel, and gathering evidence to establish fire cause. No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application Application of this unit is relevant to fire investigators who are required to determine the origin and cause of a structure fire. The unit focuses on the skills and knowledge required to develop and apply a systematic approach to fire investigation in a structure environment.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.
Prerequisites/co-requisites PUAFIR302B Suppress urban fire (Fire sector specific)PUALAW001B Protect and preserve incident scene (Fire sector specific)PUALAW002B Conduct initial investigation at incident scene (Fire sector specific)

Elements of Competency Performance Criteria              
Element: Coordinate structure fire investigation
  • Roles and responsibilities of multi-agency and supportpersonnel involved in a structure fire investigation are confirmed
  • Cooperation with multi-agency personnel in the conduct of the investigation consistent with designated roles and responsibilities for a structure fire investigation is achieved
  • Information required by fire investigator from multi-agency personnel is identified, sought and received
  • Protective clothing and equipment are used in accordance with agency procedures
  • Occupational health and safety (OHS) procedures appropriate to the incident are followed
       
Element: Secure fire scene and preserve evidence
  • Legal obligations of fire scene investigators are adhered to throughout the investigation
  • Methods of scene security prior to examination are implemented
  • Procedures to monitor and log access to a fire scene are established and applied, as required
  • Strategies for locating, collecting and processing evidence are implemented
  • Methods of preservation of evidence at a fire scene are implemented
  • Scene is protected from unnecessary damage, spoliation, destruction or contamination
       
Element: Conduct scene investigation
  • External and internal survey of scene is conducted to identify hazards and action is taken to mitigate risk
  • Scene is examined externally and internally to determine areas of interest and to record observation of factors which may have a bearing on the origin, cause or development of a structure fire
  • Areas or items of evidence that have a potential bearing on the origin, cause or development of a structure fire are identified
  • Effect of building construction and other factors relevant to fire development and spread are identified
  • Nature and reactivity of materials involved in fire cause are identified
  • Site indicators of fire spread with other sources of evidence are examined
  • Witness and firefighter information is obtained in accordance with the rules of evidence
  • Significance of evidence is assessed and prioritised for further review
  • Burn patterns and effects of fire suppression are identified and assessed
  • Area/likely point of origin and possible cause of structure fire are determined
  • Origin and cause determination theories are assessed and tested
       
Element: Collect and analyse evidence from a fire scene
  • Appropriate sampling areas and items are identified using required sampling equipment and resources
  • Appropriate collection techniques are applied eliminating contamination and loss of evidence
  • Best available samples and items including control samples are collected
  • Appropriate collection and packaging techniques are adopted
  • Potential for destruction (spoliation) and contamination of evidence is eliminated
  • Integrity and continuity of collected exhibits is maintained
  • Evidence from fire scene is analysed and processed using a range of recording and technological media
  • Witness accounts are reviewed against theories
  • Findings are reported and documented according to required practice and agency policy
  • Evidence is secured for subsequent action
  • Investigation report is completed and forwarded to appropriate authorities/stakeholders
       


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessment must confirm the ability to:

collect and maximise the potential evidentiary value of physical evidence

apply safe work practices at a fire scene

identify area/point of origin and possible cause of fire

apply evidence and forensic scientific principles to assess possible area/point of origin and causes.

Consistency in performance

Competency should be demonstrated over time and across a range of workplace and/or simulated situations.

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in the workplace and in a simulated workplace environment.

Specific resources for assessment

Access is required to:

legislation, policy, procedures and protocols relating to gathering and managing evidence

case studies and workplace scenarios to capture the range of causes likely to occur for which evidence needs to be gathered and managed.

Guidance information for assessment

Assessment methods suitable for valid and reliable assessment of this unit may include a combination of:

case studies

demonstration

observation

questioning

scenarios

authenticated evidence from the workplace.

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This describes the essential skills and knowledge and their level, required for this unit.
