Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
1. Coordinate fire investigation | 1.1 Roles and responsibilities of multi-agency and support personnel involved in fire investigation are confirmed 1.2 Cooperation with multi-agency personnel in the conduct of the investigation consistent with designated roles and responsibilities for the fire investigation is achieved 1.3 Information required for the fire investigation from multi-agency personnel is identified, sought and received 1.4 Protective clothing and equipment are used 1.5 Occupational health and safety (OHS) procedures appropriate to the incident are followed |
2. Identify, assess and collect circuitry components and appliances | 2.1 External and internal survey of fire scene is conducted to identify and assess electrical circuitry, electrical equipment and appliances 2.2 Relevance of electrical circuitry, electrical equipment and appliances to fire cause is assessed and established 2.3 Arrangements are made for the attendance of a specialist electrical fire investigator, or government or private specialist investigators, where it is believed that electrical systems, components or appliances may have contributed to the fire 2.4 Local expertise is sourced, where required 2.5 Interviews are conducted 2.6 Circuitry plans/layouts are sourced 2.7 Areas or items of evidential value relevant to the investigation at the fire scene are identified and preserved 2.8 Evidence is recorded and collected at the fire scene and relevant observations are documented 2.9 Electrical circuitry components, equipment and appliances of evidential value are protected |
3. Arrange for tests on electrical evidence collected | 3.1 Advice is received from the specialist fire investigator (electrical), or government or private specialist investigator, as to the tests required of evidence relating to electrical systems or appliances 3.2 Arrangements are made for laboratory and specialist testing and assessment of electrical items of evidential value |
4. Interpret and record findings | 4.1 Circuitry components on site plans are documented to support evidence and conclusions 4.2 Basic circuit diagrams and electrical plans relating to building, components and equipment are interpreted 4.3 Report providing expert opinion concerning the potential of electrical circuitry or equipment failure to contribute to the cause of fire is obtained 4.4 Expert findings relating to potential electrical circuit component or appliance contributions to ignition are considered in conjunction with other observations and evidence from the fire 4.5 Product recall and material safety data sheet databases are researched, as appropriate 4.6 Recommendations are forwarded to appropriate authorities/ stakeholders, as required 4.7 Findings are interpreted and recorded according to required practice and agency policy |
Required Skills
This describes the essential skills and knowledge and their level, required for this unit. |

Evidence Required
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessment must confirm the ability to: methodically examine fire scenes in which electrical installations may have a potential relationship demonstrate knowledge of basic electrical circuitry apply relevant laws, legislation, codes of practice and relevant standards to fire investigation document findings identifying components of electrical equipment (prior to and post fire) and relationships (or not) to any possible electrical causes of ignition to a fire scene. 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 or in a simulated workplace environment. Specific resources for assessment Access is required to: various electrical circuitry, electrical equipment and appliances fire scene or simulation electrical circuitry, electrical equipment and appliances damaged by electrical faults which resulted in fire legislation, policy, procedures and protocols relating to gathering and managing evidence case studies and workplace scenarios to capture the range of offences 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. |
