Elements and Performance Criteria

  1. Collect weather information
  2. Interpret weather information
  3. Analyse, record and communicate fire weather information

Required Skills

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

Required Skills

access weather recording data weather maps and webbased weather products

implement strategic risk analysis techniques

interpret fire weather source data

interpret topographic maps in order to assess effects on weather

manage data and maintain accurate records

use and interpret weather maps

Required Knowledge

effects of topography on weather and fire behaviour

fire behaviour factors

observation analysis and interpretation of weather signs

sources of data relating to weather and fire behaviour

Evidence Required

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 a wildfire an accurate analysis and projection of weather affecting a local area and the probable impact on fire behaviour

Consistency in performance

Competency should be demonstrated over time in actual andor simulated workplace environments

Context of and specific resources for assessment

Context of assessment

Competency should be assessed in an operational environment or in an agencyapproved simulated workplace environment

Specific resources for assessment

Access is required to

range of actual or simulated conditions

range of sources of information related to weather conditions and fire behaviour

agency templates for weather recording

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 andor 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 agencyapproved 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
