Elements and Performance Criteria

Tools and equipment to odourise gas may include odourmeter; tools such as lance, hoses, regulators; emergency response kit including absorption material; sodium hypochloriate (neutraliser); masking agent; reference standard; level indicator (magnetic detector); personal protective equipment; fire extinguishers; emergency container; transfer pump; molecular sieve for venting
Emergency response may include gas leaks and fire; equipment failure; hazards and incidents
Documentation may include SOPs; OH&S and environmental legislative requirements; manufacturer's specifications; Australian standards

Critical aspects of evidence
Operational safety; environmental and safety legislation; correct odourant levels; waste management 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 tools and equipment for odourising gas; 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 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 307 A Launch and Recover PIG, 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 and Unit UTG NGS 316 A Co-ordinate Construction, Laying and Testing of Gas Distribution Pipelines and the 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 knowledge of appropriate dosing levels; demonstrate knowledge of odourising system; operate equipment used to measure odourant levels; adhere to MSDS procedures; demonstrate knowledge of odourising agents; manage and dispose waste in accordance with SOPs, environmental and legislative requirements including emergency procedures; correctly and safely handle chemicals; accurately measure, fill and adjust odourant levels; understand and apply SOPs
