routine problems faults and their symptoms and the corrective action to be taken

process materials and conditions at the location of the fitting

function and troubleshooting for addressing leaks

relevant environmental requirements

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

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 nonflared tube fitting joint in accordance with the organisations 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 industrybased 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

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.

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

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

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.
