NWPTRT012
Operate and control fluoride addition process


Application

This unit describes the skills required to monitor and operate fluoridation processes and to report on water quality control.

This unit applies to those working as water operators responsible for fluoridation processes in water treatment. It may be a requirement for compliance with state and territory legislation and government water quality guidelines.

The skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to, particularly those relating to WHS.

Those undertaking this unit would work under supervision, while performing routine tasks, in a range of familiar contexts.

No licensing, legislative or certification requirements apply to unit at the time of publication.

Evidence of Performance

Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. To be deemed competent the candidate must be assessed in at least one of the fluoridation processes listed in the Range of Conditions. If not otherwise specified the candidate must demonstrate evidence of performance of the following on at least one occasion.

applying policies, regulatory standards and standard operating procedures relevant to fluoridation

receiving, clarifying and confirming work instructions

performing chemical dosing calculations

identifying and reporting control system faults and operational problems

identifying and reporting hazards

using literacy skills to produce reports and logs and interpreting a range of workplace documents

interpreting and following safety data sheets (SDS)

preparing for 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


Evidence of Knowledge

Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. If not otherwise specified the depth of knowledge demonstrated must be appropriate to the job context of the candidate.

properties of fluoridation chemicals

fluoridation and its relationship to public health

fluoride sampling and record keeping

fluoride addition points

fluoride system layout and security

policies and standard operating procedures for fluoride processes

safe handling using SDS and disposal of fluoride compounds

risk factors and potential hazards associated with fluoridation

work-related fluoride calculations

fluoride dosing processes

automatic feed rate control systems


Assessment Conditions

Competency should be assessed in an actual workplace or in a simulated environment, with access to equipment and infrastructure appropriate to the outcome. Competency should be demonstrated over time to ensure the candidate is assessed across a variety of situations.

Some components of this unit require assessment in a workplace environment therefore the unit is not suitable for fully external or electronic based assessment.

Consideration must be given to holistic assessment for this unit. Refer to advice in the companion volumes.

Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors.
