Required Skills and Knowledge

This section describes the skills and knowledge required for this unit.

Required skills 

  • identify and respond to operational problems
  • produce reports and logs

  • communicate effectively with colleagues to determine work requirements and report information using clear and direct communication appropriate for the audience and context
  • work effectively as part of a team
  • use organisation's communication equipment
  • receive, clarify and confirm work instructions
  • perform chemical dosing calculations
  • prepare and apply fluoride dosing
  • identify and report control system faults
  • identify and report hazards
  • perform fluoride residual sampling and testing
  • use literacy skills to produce reports and logs and interpret a range of workplace documents
  • interpret and follow material safety data sheets (MSDS)

Required knowledge :

  • properties of fluoridation chemicals
  • fluoridation and its relationship to public health
  • fluoride sampling and record keeping
  • fluoride addition points
  • fluoride system layout and security
  • lock-out procedures for mechanical and electrical installations
  • policies and standard operating procedures for fluoride processes
  • organisation's communication systems and procedures
  • safe handling and disposal of fluoride compounds
  • risk factors and potential hazards associated with fluoridation
  • work-related fluoride calculations
  • fluoride dosing processes
  • equipment operation, capacity and limitations
  • effects of weather and conditions on operation of site or plant
  • pumping and valving systems
  • automatic feed rate control systems
  • MSDS

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 the Training Package.

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

The candidate should demonstrate the ability to monitor, operate and report on fluoridation processes by:

  • scheduling work
  • selecting and using appropriate tools and equipment, including personal protective equipment
  • calculating average fluoride concentrations
  • collecting process samples and determining fluoride residuals
  • collecting and reporting process data
  • preparing and applying fluoride dosing safely
  • completing log sheets

Context of and specific resources for assessment 

Access to the workplace and resources including:

  • documentation that should normally be available in a water industry organisation
  • relevant codes, standards and government regulations

Where applicable, physical resources should include equipment modified for people with disabilities.

Access must be provided to appropriate learning and assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed.

Validity and sufficiency of evidence requires that:

  • competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace
  • where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice
  • a decision of competence should only be made when the assessor has complete confidence in the person's competence over time and in various contexts
  • all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence
  • where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time
  • assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit

In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator and cultural issues that may affect responses to the questions, and will reflect the requirements of the competency and the work being performed.

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised  wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
