Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a Unit of Competency.

Performance Criteria describe the required performance needed to demonstrate achievement of the element. Where bold italicised  text is used, further information is detailed in the Range Statement. Assessment of performance is to be consistent with the Evidence Guide.

Elements and Performance Criteria

ELEMENT 

PERFORMANCE CRITERIA 

1. Analyse factors impacting on the spread and behaviour of an intermediate wildfire and develop an incident prediction 

1.1 Information on the current and future fire spread and fire behaviour  is collected from a range of sources  and recorded.

1.2 Analysis is conducted using consideration of fuels and fuel assessment , weather analysis , the effects of topography  and likely resultant fire behaviour.

1.3 Fire prediction tools and references  are effectively utilised in the analysis of fire spread and behaviour.

1.4 Results of the fire behaviour analysis are validated against fire observations as they become available.

2. Develop maps and data, and maintain associated information regarding projected fire spread and behaviour 

2.1 Necessary map information and data  is prepared.

2.2 Fire spread and behaviour projections are developed in a manner appropriate to the incident.

2.3 Use of the information in planning the control of the incident is facilitated through quality, timeliness and presentation of the information.

2.4 Fire spread and fire behaviour projections are updated as new weather and fire information becomes available.

3. Analyse and communicate key risks of the projected fire spread and behaviour 

3.1 Site information is sought from agency databases or experts.

3.2 Area and timing of potential future impact of the fire is projected.

3.3 Key risks  of the fire to human, economic and environmental assets  are considered.

3.4 Fire and weather are monitored to assess if or when fire danger is likely to suddenly increase.

4. Prepare and analyse a range of fire suppression options consistent with incident objectives 

4.1 Range of options with an analysis of probable level of success and consequences of failure is prepared for consideration by the Incident Management Team.

4.2 Time available and the threshold fire behaviour for which each strategy  and tactic  is likely to be effective are considered.

4.3 Projected changes to or variation in fire behaviour conditions (due to fuel, weather, topography, fire size) are considered.

4.4 Advice and analysis are provided to the Incident Management Team to assist in development of strategies and fallback strategies.

Required Skills and Knowledge

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

Required Skills 

  • access and interpret weather products
  • implement strategic risk analysis techniques
  • interpret fire spread source data
  • manage data and maintain accurate records
  • understand and interpret topographic maps in order to plot potential fire spread
  • use fire prediction tools and suppression guides

Required Knowledge 

  • categories of risk
  • conditions suitable for and the limitations of fire suppression strategies
  • effects of topography on fire behaviour
  • fire behaviour factors
  • fire suppression strategies and tactics
  • fire weather
  • fuel and fuel assessment
  • sources of data relating to fire behaviour

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for this Training Package.

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

Assessment must confirm the ability to:

  • provide (for use by the Incident Management Team to plan the control of an intermediate wildfire):
  • accurate analysis and projection of fire spread and fire behaviour, indicating probable and possible scenarios
  • analysis of a range of appropriate fire suppression options

Consistency in performance 

Competency should be demonstrated over time in actual or simulated wildfire incidents.

Context of and specific resources for assessment 

Context of assessment 

Competency should be assessed in a range of actual or simulated wildfire incidents.

Specific resources for assessment 

Access is required to:

  • range of actual or simulated fires
  • range of sources of information related to fire spread and behaviour
  • agency templates for fire behaviour prediction

Method of assessment 

In a public safety environment assessment is usually conducted via direct observation in a training environment or in the workplace via subject matter supervision and/or mentoring, which is typically recorded in a competency workbook.

Assessment is completed using appropriately qualified assessors who select the most appropriate method of assessment.

Assessment may occur in an operational environment or in an agency-approved simulated work environment. Forms of assessment that are typically used include:

  • direct observation
  • interviewing the candidate
  • journals and workplace documentation
  • third party reports from supervisors
  • written or oral questions
