Select and use utilities and services


Application

This unit of competency covers skills and knowledge required to select and use a range of utilities and services in the plant.

This unit of competency applies to operators who are required to select the appropriate utility/service from those provided to the plant and recognise and respond to operational problems.

This unit of competency applies to an individual who may work alone although under routine direction and supervision. They may work as part of a team or group and will work in liaison with other shift team members and the control room operator, as appropriate.

In a typical scenario an operator will be able to identify and select utilities and services used on a day-to-day basis. These will be provided to a process plant and will consist of instrument and plant air, nitrogen, plant water, steam, flushing oil and other utilities/services required for a particular process. The operator uses these utilities/services as required. The correct use and application of these substances is essential to plant and operator safety and the continued performance of the process.

This unit of competency applies to any/all service utilities which form part of the utility system for the plant, typically:

steam (saturated and superheated)

air (process, instrument and breathable)

water (cooling, boiler feed, plant and waste)

inert atmosphere (nitrogen and carbon dioxide)

flushing oil.

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

Evidence of Performance

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria, and include the ability to:

select the required utility/service

recognise early warning signs of equipment/processes needing attention or with potential problems

determine the most likely cause of routine problems

take appropriate action to ensure a timely return to full performance

isolate the causes of problems to an item of equipment within the production system and to distinguish between causes of problems/alarm/fault indications, such as:

instrument failure/malfunction

electrical failure/malfunction

mechanical failure/malfunction

variations in product parameters (temperature, flows, pressure and levels)

identify hazards and apply hazard control procedures.


Evidence of Knowledge

Evidence must be provided that demonstrates knowledge of:

all items on a schematic of the utilities system and the function of each

differences between grades/types of services (e.g. grades of steam, air and nitrogen)

differences in use and methods between each service and utility

hazards that may arise in the job/work environment, and:

their possible causes

potential consequences

appropriate risk controls

physics and chemistry relevant to the utility and its use

process parameters and limits, including temperature, pressure, flow and pH

routine problems, faults and their resolution

relevant alarms and actions

types and causes of utility problems within operator's scope of skill level and responsibility.


Assessment Conditions

The unit should be assessed holistically and the judgement of competence based on a holistic assessment of the evidence.

The collection of performance evidence:

should occur over a range of situations which include typical disruptions to normal, smooth operation of an operating plant

will typically include a supervisor/third-party report or other evidence, focusing on consistent performance and problem recognition and solving. A supervisor/third-party report must be prepared by someone who has a direct, relevant, current relationship with the person being assessed and who is in a position to form a judgement on workplace performance relevant to the unit of competency

must include the use of an appropriate industrial item of equipment requiring selection and use of utilities and services and responding to problems

may use industry-based simulation for part only of the unit where safety, lack of opportunity or significant cost is an issue.

Assessment should occur in operational workplace situations. Where this is not possible, or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment reflecting realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.

Assessment in a simulated environment should use evidence collected from one or more of:

walk-throughs

pilot plant operation

demonstration of skills

industry-based case studies/scenarios

‘what ifs’.

Knowledge evidence may be collected concurrently with performance evidence (provided a record is kept) or through an independent process, such as workbooks, written assessments or interviews (provided a record is kept).

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.

The regulatory framework will be reflected in workplace policies and procedures and is not required to be independently assessed.

Foundation skills are integral to competent performance of the unit and should not be assessed separately.

Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.

In addition, the assessor or anyone acting in subject matter expert role in assessment must demonstrate both technical competency and currency. If the assessor cannot demonstrate technical competency and currency they must assess with a subject matter expert who does meet these requirements.

Technical competence can be demonstrated through one or more of:

relevant VET or other qualification/Statement of Attainment

appropriate workplace experience undertaking the type of work being assessed under routine and non-routine conditions

appropriate workplace experience supervising/evaluating the type of work being assessed under routine and non-routine conditions

Currency can be demonstrated through one or more of:

being currently employed undertaking the type of work being assessed

being employed by the organisation undertaking the type of work being assessed and having maintained currency in accordance with that organisation’s policies and procedures

having consulted/had contact with an organisation undertaking the type of work being assessed within the last twelve months, the consultation/contact being related to assessment

conducting on-the-job training/assessments of the type of work being assessed

being an active member of a relevant professional body and participating in activities relevant to the assessment of this type of work


Foundation Skills

This section describes those language, literacy, numeracy and employment skills that are essential to performance.

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
