Assessment requirements

Modification History

Performance Evidence

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 legislation, documentation, policies and procedures
• implements the requirements, procedures and techniques for the safe, effective and efficient implementation of the ventilation management plan including:

• performing routine operational mathematical calculations (quantity, pressure, prediction)
• interpreting and applying design criteria for ventilation systems and devices
• interpreting computer spreadsheets and ventilation modelling/simulations
• conducting enquiries/investigations and preparing reports
• accessing, interpreting and applying data from monitoring systems and equipment
• implementing the ventilation management training plan
• applying risk management processes and techniques
• implementing emergency response and evacuation procedures

• demonstrates completion of the implementation of the ventilation management plan that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:

• operating hand held monitoring equipment
• accessing and analysing ventilation information
• measuring air quality and quantity
• collecting, collating and interpreting ventilation data
• auditing components of the ventilation management plan

Knowledge Evidence

The candidate must demonstrate knowledge in implementing the ventilation management plan through:

• mine fires; the types, sources of ignition, possible effects on the ventilation circuit and prevention/control/mitigation methods
• mine explosions; types, ignition sources, possible effects on the ventilation circuits and prevention/control/mitigation methods
• pressure changes; causes, impacts on the ventilation system, and responses (to include the causes and effects of natural ventilation and re-circulation)
• heat/humidity; sources and factors which may impact on mine ventilation and personnel
• mine fans including:
• ventilation control devices; types, purposes, design criteria and specifications, distribution/placement criteria and limitations
• de-gassing; methods of control – including brattice, auxiliary fans, compressed air venturis, sails, hurdles and bleeders
• fixed ventilation monitoring systems types, uses and limitations
• basic computer-based systems used for mine ventilation monitoring and analysis
• ventilation surveys; the types, frequency and method for conducting
• ventilation theory including:

• psychrometry and heat

• equivalent office calculation and Kirchoff’s laws

Assessment Conditions

• 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 is best assessed in the context of this sector’s work environment;
• where personal safety or environmental damage are limiting factors, assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of this sector’s workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills; 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:

Industry sector	AQF** Level	Required assessor or Industry subject matter expert experience
Drilling, Metalliferous Mining, Coal Mining, Extractive (Quarrying) and Civil Construction	1	1 Year
	2	2 Years
Drilling, Coal Mining and Extractive (Quarrying)	3-6	3 Years
Metalliferous Mining and Civil Construction	3-6	5 Years
Other sectors	Where this Unit is being assessed outside of the Resources and Infrastructure Sectors assessor and/or Industry subject matter expert experience should be in-line with industry standards for the sector in which it is being assessed and where no Industry standard is specified should comply with any relevant regulation.

*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
