Description
This unit covers the competence to develop, apply and validate significant modifications to existing gas fuel systems in order to sustain, vary or enhance performance. Licensing, legislative, regulatory or certification requirements may apply to this unit in some jurisdictions. Users are advised to check with the relevant regulatory authority.
Notes
Elements and Performance Criteria
1. Identify and confirm the modification requirement
- 1.1. WHS requirements, including regulatory requirements, equipment and system isolation requirements and personal protection needs are observed throughout the work.
- 1.2. Purpose and objectives of the modification are identified from an analysis of inputs and confirmed with the customer.
- 1.3. Outline options for achieving the required purpose and objectives are identified, framed and presented to the customer prior to proceeding.
- 1.4. Possible legal and safety impacts of the modification are considered and responded to in accordance with regulatory and enterprise obligations and practices.
2. Develop and validate the modification specification
- 2.1. Benchmark specifications for the existing gas fuel system are accessed and interpreted.
- 2.2. Criteria to be used in the selection of the modification method and in the evaluation of the outcomes are identified and documented.
- 2.3. Proposed modification method is selected following the identification, consideration and evaluation of the full range of available and relevant options.
- 2.4. Selected option, including material choices and processes, is developed in detail and progressively validated against the established criteria.
- 2.5. Modification specification is documented to industry and enterprise standards.
3. Apply and test the modification specification
- 3.1. Selected modification method and process is followed in accordance with the established specifications.
- 3.2. Modification is completed using equipment, tooling and materials in accordance with accepted industry standards and practices.
- 3.3. Tests and testing equipment are applied in accordance with regulatory requirements, manufacturer/component supplier specifications and modification specification.
- 3.4. Test results and other diagnostic findings are verified, if necessary, by using reliable alternate or optional processes.
- 3.5. Variations necessitated during the modification process or as a result of testing are incorporated into the modification specification.
- 3.6. Information and detail related to the modification is documented and provided to the appropriate parties in accordance with regulatory and commercial obligations.
4. Clean up work area and maintain equipment
- 4.1. Materials that can be reused is collected and stored.
- 4.2. Testing equipment and other support materials are cleaned, maintained and prepared ready for further use or stored in accordance with manufacturer/component supplier specifications and enterprise requirements.
- 4.3. Waste and scrap is removed following workplace procedures.
- 4.4. Unserviceable equipment is tagged and faults identified in accordance with workplace procedures.
- 4.5. Equipment and work area are cleaned and inspected for serviceable condition in accordance with workplace 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.
Gas fuel systems modifications
Gas fuel systems modifications to be covered by this unit may include those to:
enhance engine performance
maintain emissions
meet Australian Design Rules
meet legislative requirements retrospectively.
Inputs to the modification method and processes
Inputs to the modification method and processes may be obtained from customer requirements, manufacturer/ component supplier specifications, outcomes of diagnostic processes or from regulatory, licensing, intellectual property legislation, safety requirements and Australian Design Rules.
Unit context
WHS requirements include legislation, vehicle industry regulations, safety management systems, hazardous substances and dangerous goods code and safe operating procedures.
Work is carried out in accordance with legislative obligations, Australian Design Rules, environmental legislation, health regulations, manual handling procedures and organisation insurance requirements.
Work requires individuals to demonstrate research, analytical, judgement and problem-solving skills in the diagnosis of faults.
Evaluation criteria
Evaluation criteria, sometimes referred to as success factors, are to be established prior to a modification being undertaken and are to cover safety, functionality, survivability, maintainability, life cycle cost and aesthetics.
Isolation procedures
Equipment isolation procedures are to be to industry and enterprise standards.
Tests and testing equipment
Tests and testing equipment is to include that appropriate to the modification being carried out but it should include computer-based diagnostic systems.
Personal protective equipment
Personal protective equipment is to include that prescribed under legislation, regulations and enterprise policies and practices.
Information and procedures
Workplace procedures relating to the use of tooling and equipment.
Workplace procedures relating to reporting and communication.
Manufacturer/component supplier specifications and application procedures for testing equipment and materials.
Manufacturer/component supplier specifications, schematics and operational procedures related to gas fuel systems modification.
Australian Design Rules.
Gas fuel vehicle regulations.
Vehicle industry publications related to emerging transmission system technology and technology changes.

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
Interpret work order and locate and apply information.
Apply safety requirements, including the isolation of equipment and use of personal protective equipment.
Follow work instructions, operating procedures and inspection processes to:
minimise the risk of injury to self and others
prevent damage and wastage of goods, equipment and products
maintain required production output and product quality.
Modify a significant gas fuel system or sub-system including:
selection, development and documenting of success factors and evaluation criteria before undertaking the modification
selection, development and validation of the modification methodology, processes and specification
application of modification specification, methodology and process
the documenting and reporting of the outcomes.
Work effectively with others.
Modify activities to cater for variations in workplace context and environment.
Context of, and specific resources for assessment
Assessment may occur on the job or in a workplace simulated facility with process equipment, materials, work instructions and deadlines.
Access to an operational gas fuel system requiring modification, testing equipment as stipulated in the Range Statement, technical information and a work environment.
Method of assessment
Assessment of this unit of competence is most likely to be project related and require portfolios or other forms of indirect evidence of process. Direct evidence will include certification of compliance of the final outcome/product or authorisation for use by a competent authority.
Assessment must confirm the inference that competence is able not only to be satisfied under the particular circumstances, but is able to be transferred to other projects.
Competence in this unit may be assessed in conjunction with other functional units which together form part of the holistic work role.
