Qualification -
Unit of Competency PMASUP244A - Prepare and isolate plant
Description This unit of competency covers the skills and knowledge needed to isolate and prepare plant for subsequent work, typically maintenance of some sort. It also includes preparing the plant for return to service.
Employability Skills This unit contains employability skills
Learning Outcomes and Application This unit applies to a person who has the responsibility for isolating and preparing plant. This is probably part of their work role, although it could be a full time secondment for a major shutdown. The type of people to whom this unit may apply include (but are not limited to):operators, and maintainersmaintenance personnel.While this unit is written to apply to an individual they will usually undertake it in liaison with relevant experts and stakeholders.This unit applies:after the isolation and preparation plan has been authorisedbefore the work commences.This unit has a strong relationship with the relevant ‘permit’ units (e.g. MSAPMPER200B Work in accordance with an issued permit and MSAPMPER300C Issue work permits) and decommissioning/recommissioning units (e.g. PMASUP440B Commission/recommission plant and PMASUP441C Decommission plant). Where relevant, these units should also be accessed.This unit requires a detailed knowledge of the plant to be prepared and isolated, such as might be obtained from the relevant technical units covering this plant. Hands-on operating competency, however, is not necessarily required.This unit does not include the planning for the isolation and preparation of plant - see PMASUP444A Plan plant preparation and isolation.This unit has been written with the preparation and isolation of hazardous plant, such as a major hazard facility in mind. However, it should also be applicable to the preparation and isolation of lower hazard plants and mobile plant with appropriate contextualisation.Much of this unit is iterative and the text below should not be taken as specifying necessary sequence.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.
Prerequisites/co-requisites Not applicable.

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

This unit should be assessed as holistically as is practical and will generally be assessed using a workplace project as a significant assessment activity.

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

A person who demonstrates competency in this unit must be able to provide evidence of the ability to:

perform isolations to plan for a significant item of equipment or plant area

prepare plant for the work to plan

prepare plant for return to service to plan.

Context of and specific resources for assessment

Assessment of performance must be undertaken in a workplace.

Access may be required to:

workplace procedures and plans relevant to work area

specifications and documentation relating to planned work

documentation relating to the plant, process and materials

the isolation and preparation plan

any other materials which would normally be available in the workplace while conducting this activity.

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.

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assignment, checklist) and due date here

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills include:

Ability to:

read and interpret technical documentation and drawings/graphics

inerpret material safety data sheets (MSDS)

interpret test results (e.g. for atmosphere/gas testing and leak testing)

Required knowledge includes:

Knowledge of:

work control system for site and organisation

existence of regulations and other external controls relevant to the proposed work

isolation philosophy of organisation

isolation and preparation plan for work

plant energy sources and their methods of being de-energised and isolated

hierarchy of isolations

methods of proving isolations

methods and equipment used for purging and ventilation

physical properties of process materials (e.g. density and viscosity)

hazardous properties of relevant materials (e.g. process, purging and ventilation materials)

decontamination methods and requirements for various materials and situations

as low as reasonably practicable (ALARP) concept

importance of appropriate rates of change for pressure and temperature for vessels and other plant

significance of time allowed for draining, purging, ventilation

fluid dynamics relating specifically to draining piping systems:

the ability of a liquid to ‘hang-up’ in pipework, the importance of identifying high point vents to release gas/vapours and low point drains to release liquids

determining the amount of liquid drained from a piping section to ascertain that draining has been effective/prove drainage

the potential effects (e.g. damage to tanks or vessels) of vacuum by not draining correctly (e.g. by pulling a vacuum behind a slug of liquid)

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.

Isolation

Isolation is a process for ensuring no energy or material can enter the isolated area

Plant energy sources

Plant energy sources may include, but are not limited to:

Required paperwork

Required paperwork may include, but is not limited to:

atmosphere/gas testing

testing the restoration of utilities and services

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
