Application
This unit involves the skills and knowledge required to test switches, crossings and other special components in turnouts using ultrasonic and other nondestructive testing equipment in accordance with rail industry standards, safeworking and regulatory requirements, and workplace procedures. It includes determining test requirements, conducting ultrasonic testing using hand directed equipment, conducting nondestructive testing, classifying defects and completing all required documentation. People achieving competence in this unit will need to fulfil the applicable state/territory legislated rail safety requirements and to comply with relevant codes of practice and/or guidelines. Work is performed under some supervision, generally within a team environment. It involves the application of routine operational principles and procedures when testing turnouts using nondestructive testing equipment, as part of workplace activities across a variety of operational contexts within the Australian rail system. No licensing, legislative or certification requirements apply to this unit at the time of publication. |

Evidence of Performance
Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria on at least three separate occasions and include: |
adapting to differences in equipment in accordance with operating procedures applying relevant workplace procedures checking and maintaining nondestructive testing equipment checking turnouts for observable faults conducting visual examinations identifying job hazards and taking required action to minimise, control or eliminate identified hazards identifying types of rail defects in switches and crossings implementing contingency plans interpreting and following relevant operational instructions and prioritising work locating, measuring and assessing defect size for all defect types modifying activities depending on operational contingencies, risk situations and environments monitoring work activities in terms of planned schedule reading and interpreting relevant technical data, drawings, instructions and manuals reporting and/or rectifying identified problems, test results, faults or malfunctions, in accordance with workplace procedures working systematically with required attention to detail without injury to self or others, or damage to goods or equipment. |
Evidence of Knowledge
Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of: |
hazards that may exist when testing turnouts and rail using nondestructive testing equipment, and ways of controlling the risks involved problems that may occur when testing turnouts and rail using nondestructive testing equipment, and action that can be taken to report or resolve these problems relevant rail danger zones relevant recording and documentation procedures relevant safety, work health and safety (WHS)/occupational health and safety (OHS) and environmental procedures and regulations relevant workplace technical manuals and instructions required to test switches, crossings and other special components in turnouts using ultrasonic and other nondestructive testing equipment special inspection requirements for alloy hardened crossings types of rail defects found in turnouts and rail defect classification ultrasonic testing requirements for turnouts and special trackwork workplace procedures for testing turnouts and rail using nondestructive testing equipment. |
Assessment Conditions
As a minimum, assessors must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment. As a minimum, assessment must satisfy applicable regulatory requirements, which include requirements in the Standards for Registered Training Organisations current at the time of assessment. Assessment must occur in workplace operational situations or, where this is not available, in simulated workplace operational situations that replicate rail corridor workplace conditions. Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate. Resources for assessment include: a range of relevant exercises, case studies and/or simulations relevant and appropriate materials, tools, equipment and personal protective equipment currently used in industry applicable documentation including workplace procedures, regulations, rail industry standards, codes of practice and operation manuals. |
