Elements and Performance Criteria

Pressure vessels and fittings may include such items as pressure vessel; vaporisers; earth connections; relief valves; emergency shut-down valving (eg. ISC valves); manual shut-down valving; pipework; vessel footings; regulators; hoses and couplings; pumps; compressors
Types of variations or irregularities may include corrosion; impact damage; point deterioration; leakage; non-operability of shutdown systems; equipment out of calibration.
Appropriate parts to be replaced may include excess flow valves; relief valves; pressure regulators/springs; pump seals/compressor seals; pressure gauges; bypass valves; meters; solenoids; valves; break away couplings; meter heads
Type of adjustments include downstream pressure adjustment; storage pressure adjustment (vaporiser systems only); bypass pressure adjustment for pumps
Documents may include SOPs; OH&S and environmental legislative requirements; Australian Standards; manufacturer's specifications; work permits
Documentation may require the use of PC's or other electronic media.

Critical aspects of evidence
Inspecting and testing procedures; adjusting and replacing procedures; adhering to SOPs; OH&S legislative requirements; correctly diagnosing and assessing faults; applying correct maintenance procedures

Context of assessment
Assessment of competency, including attainment of relevant knowledge and skills may be made through practical demonstration in an actual work environment or simulation of such an environment. Assessment may be carried out by day or night, in varied weather conditions, but must adhere to defined safety and regulatory guidelines.

Specialised resources required for training and assessment
Appropriate equipment for maintaining processing/storage facilities; availability of suitably qualified industry assessors; system which facilitates recording of trainees' profiles and progress; facilities for workplace or simulated environment assessment

Pre-requisites and co-requisite
This unit requires, as an entry, attainment of the Certificate II in Gas Operations and related units of competence if pursuing a Certificate III in Gas Operations.
Entry may also be accepted from those who have achieved an equivalent AQF level two-qualification competency outcome. As such, they would be expected to have attained sufficient relevant underpinning knowledge and skills, which could be used to accelerate their progress through this unit to the Certificate III in Gas Operations. However, should this not be the case a suitable bridging program is to form part of the entry requirement.
Additionally, this unit should be assessed after competency has been demonstrated, Unit UTG NGS 206 A Monitor and Control Transfer of LPG, Unit UTG NGS 207 A Process LPG, and either UTG NGS 209 A Co-ordinate Repair of Faults in Gas Processing/Storage Facilities and Equipment or UTG NGS 210 A Control Storage of LPG in Terminal and the following Frontline Management III Competency Standards:
(BSXFM 1301 A) Manage Personal Work Priorities and Professional Development
(BSXFM 1302 A) Provide Leadership in the Workplace
(BSXFM 1303 A) Establish and Manage Effective Workplace Relationships and,
(BSXFM 1308 A) Develop and Maintain a Safe Workplace and Environment

Knowledge and Skills
The Evidence Guide is a set of guidelines which assist in the development of assessment instruments/tools to assess the competency of workers in the Gas Industry. This requires evidence of consistent achievement of the workplace outcomes covered by the unit.
An employee working at this level is required to demonstrate and awareness of types of test equipment and their uses; operate equipment such as pressure vessels and associated fittings as listed in the Range of Variables; identify the types of adjustments required; accurately replace and adjust parts in accordance with manufacturer's specifications; perform tasks associated with the inspecting and testing of pressure vessels; identify and report faults in pressure vessels; perform tests on equipment; understand and adhere to SOPs; adhere to OH&S and environmental legislative requirements and guidelines; accurately record relevant information
