4Complete and review reports. | 4.1 Produce information relating to system maintenance and operation according to organisational requirements. 4.2 Review information and contribute to enterprise processes for continuous improvement and incident management. |
This describes the essential skills and knowledge and their level, required for this unit. |
Required skills: identify and respond to operational problems produce reports and logs use safety and personal protective equipment follow plans, charts and instructions apply policies, regulatory standards and standard operating procedures communicate effectively work effectively as part of a team use communication equipment give and receive instructions perform work-related ozone calculations prepare and apply ozone dosing operate computerised equipment identify control system faults identify hazards perform microbiological and ozone residual sampling use literacy skills in regard to verbal and written communication in the workplace interpret material safety data sheets (MSDS) |
Required knowledge: properties and chemistry of ozone pH microbiological water quality guidelines ozone system layout lock-out procedures for mechanical and electrical installations policies, standard operating procedures and legislation communication systems hazardous substances handling risk factors and potential hazards associated with ozonation work-related ozone calculations ozone dosing processes operation, capacity and limitations of ozone generation equipment effects of weather and conditions on operation of site or plant pumping and valving systems automatic feed rate control systems MSDS |
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 ozone treatment systems including: scheduling work selecting and using appropriate tools and equipment, including personal protective equipment monitoring ozone treatment systems collecting process samples and performing standard tests collecting and reporting process data preparing and applying ozone dosing safely producing reports |
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. |
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. Add any 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. | |
Legislative and organisational requirements may include: | relevant federal and state or territory legislation and regulations codes of practice, associated standards and guidance material documented organisational policies, manuals and induction programs relevant community planning and development agreements, such as land care agreements |
Equipment and tools may include: | electronic monitoring and metering systems recording systems basic hand and power tools sampling and laboratory testing equipment computerised equipment on- and off-road vehicles communication equipment personal protective equipment |
Ozone treatment systems may include: | electric discharge ozone-generation system UV ozone-generation system |
Tests may include: | ozone residuals exhaust gas ozone concentration pH |
