Elements and Performance Criteria

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.
Context
This competency includes disconnecting and reconnecting non-flared tube fitting joints using hand tools. It does not include:
the initial installation of tube fittings
high pressure fittings
cone fittings
Work requirements
Work requirements may include but are not limited to:
fitting, tubing and thread specifications
fitting brand
specific sealing method and type
process line and process materials
parts and equipment required
local detectors requiring isolation
required skill level
conflicting work
Work requirements may come from briefings, handovers, and work orders and may include:
compliance documentation
product specifications
nature and scope of tasks
achievement targets
operational conditions
lighting conditions
plant or equipment defects
hazards and potential hazards
coordination requirements or issues
Job site
Inspecting job site may include but is not limited to identifying:
location
authorisations required
access and egress needs
hazards
recent work undertaken on joint
fitting type (matches specification)
Control hazards
Control hazards may include but are not limited to:
selection and use of appropriate personal protective equipment
obtaining appropriate authorisations
checking required isolations
controlling other work in area
Implement hazard controls
Implementing hazard controls may include but is not limited to:
controlling access to area
using gas tester
verifying and confirming isolation
safe fitting breaking procedure (line of fire)
Inspect components
Inspecting tube fitting components may include but is not limited to checking:
full tube insertion
orientation of ferrules
correct tube deburring
for signs of damage, defects or deterioration in all components
confirming compliance of components
Components
Components may include but are not limited to:
fitting body
fitting nut
front ferrule
rear ferrule
tube
tube clamps and support saddles
Manage open tube
Manage open tube includes:
all those actions required once the joint is broken to ensure the tube and its contents are not contaminated or damaged
Refer
Refer means to refer the issue to the person with the required skills, knowledge and/or authority to deal with the matter
Procedures
Procedures may be written, verbal, computer-based or in some other form. They may include but are not limited to:
tube fitting procedures
all work instructions
standard operating procedures
temporary instructions
any similar instructions provided for the smooth running of the plant
good operating practice as may be defined by industry codes of practice

Procedures would be expected to comply with any relevant government regulations.
Checklists and records
Checklists and records may include:
paper or electronic based verbal/radio reports
reporting items found which require action
Appropriate action
Appropriate action includes but is not limited to:
determining problems needing action
accessing and applying relevant technical and plant data
applying appropriate problem solving techniques to determine 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/ability to resolve to designated person
Typical problems
Typical problems may include but are not limited to:
fitting leaks
blockages/build-up/fouling
erosion/wear
ancillary equipment problems
support clamps incorrectly attached
worn threads
misalignments
lack of full tube insertion
ferrule missing or reversed
incorrect installation
Remedial actions
Remedial actions may include but are not limited to:
replacing existing components with new components
carrying out minor maintenance within operator's skill level
identifying and reporting problems outside operator's competence
identifying and controlling hazards related to tube fitting joints
Health, safety and environment (HSE)
All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state/territory 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.

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.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Critical aspects for assessment and evidence include:
the disconnecting and reconnecting of a non-flared tube fitting joint in accordance with the organisation’s procedures
recognising own skill limits and when to refer to another person.
Context of and specific resources for assessment
Assessment of this competency will occur over a range of situations which will include typical disruptions to normal, smooth operation. This will require access to a plant over a period of time, or a suitable method of gathering evidence of operating ability. Where safety, lack of opportunity or significant cost is an issue, an industry-based simulation may be employed to assist the process.
Guidance information for assessment
Assessment processes and techniques must be appropriate to the language, competency and safety requirements of the site and consistent with workplace systems or procedures.
