Elements and Performance Criteria

Required Skills

Required skills

Required skills include

interpretation of symbols and other drawing elements

problem solving

Required knowledge

Competence includes an understanding of process plant schematics and their application to the actual plant and process In particular it includes a knowledge of

symbols used on schematics by that organisation

schematic conventions eg with particular reference to crossing and branching lines

indications of equipmentpipe specifications

indications of process conditionslimits

cause and effect interpretation as relevant

Evidence Required

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

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

Competence must be demonstrated in the ability to apply schematics to plantprocess based situations

Consistent performance should be demonstrated In particular look to see that

critical processplant features can be identified from a schematic

main process features can be described using a schematic

Context of and specific resources for assessment

Assessment will require access to a plant over an extended period of time or a suitable method of gathering evidence of ability over a range of situations A bank of scenarioscase studieswhatifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions

Method of assessment

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

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.

Codes of practice/ standards

Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.

Items

Items on schematic/in plant includes:

all major plant items such as:

heat exchangers

minor plant items

Context

Schematics have various names and includes:

P&IDs (piping and instrumentation diagrams)

PFDs (process flow diagrams)

PEFs (Process Engineering Flow)

cause and effect diagrams/matrix

Unless qualified in the unit, 'schematic' means a formally drawn, authorized schematic and may be hard copy or electronic.

Symbols

Symbols and conventions used in the schematics for the relevant plant area should be used. They may be Australian Standards symbols, the organisation's standard symbols or some other standard system:

Minor equipment

Minor equipment includes that equipment commonly described by size and type and includes:

instrumentation (local and remote)

It typically would not include items such as vessels, columns, reactors or heat exchangers which would be major plant items.

Plant preparation

Plant preparation entails all that activity which may be required to render the plant safe for non-operational work (which is typically maintenance but may be other work) and includes:

blank/spade/spectacle blind, breakout spool locations

locating plant, equipment and services - above ground

locating below ground (or otherwise obscured) pipeline and services.

Key conditions

Key conditions includes:

normal range of process conditions such as

alarm conditions/values

trip, ESD values

Work lists

Work lists may include:

spade/blind lists

Manual schematic

Manual schematic may include:

a hand drawn sketch of the part of the process of interest

a mark up of a formally drawn schematic

Schematics may be hard copy or electronic.

Appropriate action

Appropriate action includes:

determining problems needing action

determining possible fault causes

rectifying problem using appropriate solution within area of responsibility

following through items initiated until final resolution has occurred

reporting problems outside area of responsibility to designated person.

Procedures

Procedures may be written, verbal, computer-based or in some other form. They include:

all work instructions

standard operating procedures

formulas/recipes

temporary instructions

any similar instructions provided for the smooth running of the plant.

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.
