Elements and Performance Criteria

Equipment required for "pigging" operation may include valves; PIG launcher; PIG receiver; tracking equipment; pipeline locator; technical drawings; hand tools; crane; PIG signals; pilot tube; PPE; fire extinguisher; time piece
PIGs may include intelligent PIGS; batching PIGs; cleaning PIGs; foam PIGs; brush PIGs; disc PIGs; cup PIGs; spherical PIGs

Critical aspects of evidence
Use and operation of a variety of PIGs and "pigging" techniques; interpreting a range of data; waste management procedures; adhering to OH&S, SOPs, site specific safety and EPA legislative requirements

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.

Specialised resources required for training and assessment
Appropriate equipment required to maintain integrity of pipeline systems; 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.
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 in conjunction with or after competency has been demonstrated in Three of the following Units: Unit UTG NGS 303 A Commission/Decommission Pipelines, Unit UTG NGS 306 A Co-ordinate Pipeline Repair and Modifications, Unit UTG NGS 310 A Perform Routine Maintenance on Pipeline, Facilities and Equipment, Unit UTG NGS 312 A Co-ordinate Repair of Pipeline, Facilities and Equipment, Unit UTG NGS 313 A Control Gas Odourisation, and Unit UTG NGS 316 A Co-ordinate Construction, Laying and Testing of Gas Distribution Pipelines and the following Frontline Management Level 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 adhere to manufacturer's and legislative specifications and requirements; identify requirements for pipeline system set up; assemble and use the variety of PIGs; identify appropriate authorities to be advised; interpret and analyse data related to PIG process; use equipment for pigging operation in accordance with manufacturer's specifications and SOPs
