Unit Descriptor
Unit descriptor |
This competency covers the operation of the range of pumps and valves typically encountered in the fluid flow system of a processing plant. It includes identifying, operating, monitoring and troubleshooting these items. |
Application of the Unit
Application of the unit |
In a typical scenario, an operator uses a number of general purpose pumps, piping and valves to move liquids from a storage tank area into the processing plant and products to the finished goods tanks. The operator utilises in-line mixers, strainers and filters, valves, controls and meters to complete this work. The operator would:
Generally the operator would be part of a team during start up and shut down procedures and would be expected to be capable of demonstrating competence in all parts of this unit. At all times they would be liaising and cooperating with other members of the team. This unit does not require the operation of a central control panel. This competency covers all general duty pumps, their associated drivers (motors) and valves. It does not cover special duty pumps (eg hydrocarbon transmission pumps), drivers which incorporate ancillaries and valves which are used for high pressure/flow situations (see PMAOPS221 Operate and monitor prime movers , PMAOPS222B Operate and monitor pumping systems and equipment and PMAOPS223B Operate and monitor valve systems ). Competence in this unit (PMAOPS20B1 Operate fluid flow equipment ) would preclude counting PMAOPS223B Operate and monitor valve systems towards a qualification. |

Overview of assessment |
Assessment of this unit should include demonstrated competence on actual plant and equipment in a work environment. The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency. Assessment will occur over a range of situations which will include disruptions to normal, smooth operation. Simulation may be required to allow for assessment of parts of this unit. Simulation should be based on the actual plant and will include walk-throughs of the relevant competency components. Simulations may also include the use of case studies/scenarios and role plays. This unit of competency requires a significant body of knowledge which will be assessed through questioning and the use of what-if scenarios both on the plant (during demonstration of normal operations and walk throughs of abnormal operations) and off the plant. |
|
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action. The emphasis should be on the ability to stay out of trouble rather than on recovery from a disaster. Consistent performance should be demonstrated. In particular look to see that:
These aspects may be best assessed using a range of scenarios/case studies/what-ifs as the stimulus with a walk through forming part of the response. These assessment activities should include a range of problems, including new, unusual and improbable situations which may have been generated from the past incident history of the plant, incidents on similar plants around the world, hazard analysis activities and similar sources. |
|
Context of and specific resources for assessment |
Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations. A bank of scenarios/case studies/what-ifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions. |
|
Method of assessment |
In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units. Consider co-assessment with units covering:
In a major hazard facility, it may be appropriate to assess this unit concurrently with:
The assessment should cover at least one type of centrifugal pump and one type of positive displacement pump, as well as at least two different types of valves for the operator to be regarded as competent. |
|
Guidance information for assessment |
Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed. |
Range Statement
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. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts. |
|
Codes of practice / standards |
Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used. |
Context |
This competency is typically performed by all operators. It includes items of equipment such as:
The effect of pipe fittings on pump performance and problems/problem analysis is also included. All operations are performed to procedures. |
Problems |
Typical problems include:
|
Appropriate action |
Appropriate action includes:
|
Procedures |
Procedures may be written, verbal, computer-based or in some other form. They include:
For the purposes of this Training Package, 'procedures' also includes good operating practice as may be defined by industry codes of practice (eg Responsible Care) and government regulations. |

Health , safety and environment (HSE ) |
All operations to which this unit applies are subject to stringent health, safety and environment requirements, which may be imposed through State or Federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence. |
