Elements and Performance Criteria

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:
vessels,
columns,
reactors
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:
pumps
valves
strainers
filters
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:
isolations
blank/spade/spectacle blind, breakout spool locations
draining
purging
blanketing
venting
ventilating
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
level
pressure
flow
temperature
alarm conditions/values
trip, ESD values
Work lists
Work lists may include:
punch list
tag numbers
spade/blind lists
similar 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
batch sheets
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.

EVIDENCE GUIDE
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 plant/process based situations.
Consistent performance should be demonstrated. In particular look to see that:
critical process/plant 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 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

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.
