This unit describes a participant’s skills and knowledge required to inspect, test and maintain inlet systems on diesel engine systems in Coal mining.

This unit is appropriate for those working in operational roles.

Licensing, legislative, regulatory and certification requirements that apply to this unit can vary between states, territories, and Industry sectors. Relevant information must be sourced prior to application of this unit.

Evidence is required to be collected that demonstrates a candidate’s competency in this unit. Evidence must be relevant to the roles within this sector’s work operations and satisfy all of the requirements of the performance criteria of this unit and include evidence that the candidate:

locates and applies relevant documentation, policies and procedures

works effectively with others to undertake and complete the inspection, testing and maintenance of inlet systems on diesel engine systems that meets all of the required outcomes including:

using a range of communications techniques and equipment to convey information to others

maintaining written and verbal reporting requirements and procedures

communicating clearly and concisely with others to receive and clarify work instructions

demonstrates completion of inspecting, testing and maintaining inlet systems on diesel engine systems that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:

carrying out inspection of inlet systems on diesel engine systems

carrying out the inspection of inlet system flame traps for effectiveness of explosion protection

carrying out testing and fault finding of inlet systems on diesel engine systems

diagnosing and recording existing or identified faults, including blockages and constrictions

The candidate must demonstrate knowledge in when inspecting, testing and maintaining inlet systems on diesel engine systems through:

site risk, statutory compliance, health, safety, environmental, quality and communication requirements and procedures

limitations on allowable maintenance including work in hazardous environments

site and manufacturer’s requirements and procedures

tools required to be used in performance of inspection, testing and maintenance tasks

site inspection, testing and maintenance support requirements and availability

site isolation and lock-out requirements and procedures

the failure modes of the inlet system that may affect the explosion protection characteristics and the emissions from diesel engine systems

the relative performance (including emissions) of increased air induction systems

systems for the reduction of the harmful emissions from diesel engines

functions of the management and treatment systemsand principles employed to limit the creation of and to manage harmful emissions from diesel engine

An assessor of this unit must satisfy the requirements of the NVR/AQTF or their successors; and Industry regulations for certification and licensing; and,

this unit must be assessed in the context of this sector’s work environment; and,

this unit must be assessed in compliance with relevant legislation/regulation and using policies, procedures, processes and operational manuals directly related to the industry sector for which it is being assessed; and,

assessment may be conducted in conjunction with the assessment of other Units of Competency; and,

assessment must confirm consistent performance can be applied in a range of relevant workplace circumstances; and,

assessors must demonstrate the performance evidence, and knowledge evidence as outlined in this Unit of Competency, and through the minimum years of current* work experience specified below in an Industry sector relevant to the outcomes of the unit; or,

where the assessor does not meet experience requirements a co-assessment or partnership arrangement must exist between the qualified assessor and an Industry subject matter expert. The Industry subject matter expert should hold the unit being assessed (or an equivalent unit) and/or demonstrate equivalence of skills and knowledge at the unit level. An Industry technical expert must also demonstrate skills and knowledge from the minimum years of current work experience specified below in the Industry sector, including time spent in roles related to the unit being assessed; and,

assessor and Industry subject matter expert requirements differ depending on the Australian Qualifications Framework Level (AQF) of the qualification being assessed and/or Industry Sector as follows:

*Assessors can demonstrate current work experience through employment within Industry in a role relevant to the outcomes of the Unit; or, for external assessors this can be demonstrated through exposure to Industry by conducting frequent site assessments across various locations.

**Where a unit is being delivered outside of a Qualification the first numeric character in the Unit code should be considered to indicate the AQF level

Foundation skills essential to performance are explicit in the performance criteria of this unit. Further information is available in the Resources and Infrastructure Industry Training Package Companion Volume.
