Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

What evidence is required to demonstrate competence for this standard as a whole?

Competence in undertaking routine maintenance on pressurised irrigation delivery systems requires evidence that a person can inspect and replace worn parts, and follow procedures to carry out routine maintenance with only routine supervision.

The skills and knowledge required to undertake routine maintenance on pressurised irrigation delivery systems must be transferable to a different work environment. For example, this could include different systems, watering schedules and enterprises procedures.

What specific knowledge is needed to achieve the performance criteria?

Knowledge and understanding are essential to apply this standard in the workplace, to transfer the skills to other contexts, and to deal with unplanned events. The knowledge requirements for this competency standard are listed below:

enterprise and OHS procedures relating to pressurised irrigation system maintenance

major components of a pressurised irrigation delivery system

maintenance requirements and procedures for system components

environmentally safe disposal procedures for chemical containers and residues, oils/grease and used parts.

What specific skills are needed to achieve the performance criteria?

To achieve the performance criteria, appropriate literacy and numeracy levels as well as some complementary skills are required. These include the ability to:

read and follow an operators manual and manufacturers specifications for pressurised irrigation systems

maintain selected irrigation system components

record and report maintenance observations and activities.

What processes should be applied to this competency standard?

There are a number of processes that are learnt throughout work and life, which are required in all jobs. They are fundamental processes and generally transferable to other work functions. Some of these are covered by the key competencies, although others may be added. The questions below highlight how these processes are applied in this competency standard. Following each question a number in brackets indicates the level to which the key competency needs to be demonstrated where 0 = not required, 1 = perform the process, 2 = perform and administer the process and 3 = perform, administer and design the process.

1. How can communication of ideas and information (1) be applied?

Reporting damage, faulty systems and routine maintenance activities.

2. How can information be collected, analysed and organised (1)?

Recording observations of irrigation equipment in the maintenance book.

3. How are activities planned and organised (1)?

Organising task activities and equipment for maintenance activities.

4. How can team work (1) be applied?

Reporting system problems others.

5. How can the use of mathematical ideas and techniques (1) be applied?

Preparing equipment according to design specifications.

6. How can problem-solving skills (1) be applied?

Identifying and replacing damaged outlets or faulty systems.

7. How can the use of technology (1) be applied?

Using computerised irrigation systems.

Are there other competency standards that could be assessed with this one?

This competency standard could be assessed on its own or in combination with other competencies relevant to the job function.

There is essential information about assessing this competency standard for consistent performance and where and how it may be assessed, in the Assessment Guidelines for this Training Package. All users of these competency standards must have access to the Assessment Guidelines. Further advice may also be sought from the relevant sector booklet.

Range Statement

Range of Variables

The Range of Variables explains the contexts within which the performance and knowledge requirements of this standard may be assessed. The scope of variables chosen in training and assessment requirements may depend on the work situations available

What pre-season maintenance might be carried out?

Pre-season maintenance may include weed control, motor servicing, flushing and supply distribution, descaling and equipment service.

What post-season maintenance might be carried out?

Post-season maintenance may include disconnecting electrics, motor servicing, reports of equipment and machinery damage, flushing and draining, protection from environmental damage, and servicing equipment.

What enterprise standards might be relevant to flushing and cleaning the system?

These might include environmental considerations such as the identification of the impacts of pumping water from any ground or underground source and appropriate remedial action, and procedures for dealing with cleaning agents and waste water.

What safe working practices apply to dismantling and storage of equipment?

These may include safe procedures for manual handling, and the operation of machinery and equipment.

What types of pressurised irrigation systems might be relevant to this standard?

Irrigation systems may range from manual operation and monitoring to fully automated with computer control and monitoring. They may include micro-irrigation systems and spray irrigation systems. Micro-irrigation systems may be mains pressure, low pressure, below or above ground, sprays systems, drip emitter trickle, t-tape, mini-sprinklers, and capillary. Spray irrigation systems may be travelling irrigators (soft hose, hard hose boom type) centre pivot, linear move, powered side roll hand shift permanent (installed), and bike shift/easy shift.

What might servicing of mechanical equipment include?

Periodical maintenance for pumping unit may include changing engine oil, replacing the oil filter, replacing the air cleaner, checking battery water level, pre-cleaner, gear box oil, cooling system/water, fuel, battery charge and fuel tank, greasing the pump jack shaft and bearings, and flushing (de-silting) the pump.

Centre control tower maintenance may include greasing head of pivot and all gearboxes, checking tyre pressure, and cleaning electrical controls of authorised components.

There may be environmental considerations relating to the servicing of mechanical equipment such as disposal of oils/grease and used parts.

What are the OHS procedures relevant to this standard?

These might include prevention of electrical injury, protection against cleansing agents including acids, and safe systems and procedures for protection against risks of slips and falls.

What materials may be used for system maintenance?

Materials may include gland packing, rubber rings, belts and pulleys, hazardous substances, or chemicals.

What parts/replaceable system components might be inspected or replaced?

These may include pipes, jets, microjets, laterals, sprinklers, emitters, integrated dripline "thin wall", seals and outlets.

What outlets might be removed and cleaned or replaced?

Outlets may include drip lines, cups and fluming, pipes, risers, valves, sprinklers and emitters.
