Elements and Performance Criteria

Testing and application equipment may include abrasive blasting equipment; compressors; low voltage and high voltage holiday detectors; paint thickness coating gauges and meters; mobile plant; pipe wrapping machines; spray painting equipment; abrasive blast comparators and standards; densitometers; coating defect assessment survey equipment (DCVG method equipment, Pearson technique method equipment); hand/power tools; heating torch
Coatings may include heat shrink sleeves; wrapping tapes; epoxy paints; coating patches
Coating defect assessment surveys for identifying condition and location of irregularities may include DCVG method; Pearson technique method
MSDS information and handling of chemicals/flammable liquids are involved.

Critical aspects of evidence
Inspection of pipeline coatings; testing pipeline coatings; safe handling procedures for a range of dangerous and toxic chemicals and compounds; OH&S and environmental legislative requirements associated with the use, application and disposal of coating materials; coating defect assessment and application methods
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
Availability of suitably qualified industry assessors; system which facilitates recording of trainees' profiles and progress; facilities for workplace or simulated environment assessment; appropriate equipment for pipeline coating
Pre-requisites and co-requisite
This unit should be assessed in conjunction with or after competency has been demonstrated in Unit NGS 010 A Apply Procedures in the Workplace, Unit NGS 020 A Working With Others, Unit NGS 030 A Plan and Organise Work Activities and NGS 210 A Maintain Pipeline Easement.
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 comply with pipeline coating design principles; operate equipment and tools used in coating; test equipment procedures and operating parameters; use the various coating types and techniques; comply with OH&S and emergency principles and procedures; apply the basic electrical principles and measurements; use the various chemical types adhering to the appropriate safe handling procedures; apply topographic and geographic layout principles; comply with communication principles when providing; verbal, written; simple reports; forms and presentations; use computers and related technologies at a basic level; effectively analyse data
