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

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Assessment of this unit should include demonstrated competence on actual plant and equipment in a work environment. The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency. Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.

Simulation may be required to allow for assessment of parts of this unit. Simulation should be based on the actual plant and will include walk-throughs of the relevant competency components. Simulations may also include the use of case studies/scenarios and role plays.

This unit of competency requires a significant body of knowledge which will be assessed through questioning and the use of what-if scenarios both on the plant (during demonstration of normal operations and walk throughs of abnormal operations) and off the plant.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action. The emphasis should be on the ability to stay out of trouble rather than on recovery from a disaster.

Consistent performance should be demonstrated. In particular look to see that:

early warning signs of equipment/processes needing attention or with potential problems are recognised

the range of possible causes can be identified and analysed and the most likely cause determined

appropriate action is taken to ensure a timely return to full performance

obvious problems in related plant areas are recognised and an appropriate contribution made to their solution.

These aspects may be best assessed using a range of scenarios/case studies/what-ifs as the stimulus with a walk-through forming part of the response. These assessment activities should include a range of problems, including new, unusual and improbable situations which may have been generated from the past incident history of the plant, incidents on similar plants around the world, hazard analysis activities and similar sources.

Context of and specific resources for assessment

Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations. A bank of scenarios/case studies/what-ifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions.

Method of assessment

In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units. For many plants, it might be appropriate for this unit to be assessed with units covering:

fluid flow

communication.

In a major hazard facility, it may be appropriate to assess this unit concurrently with:

MSAPMOHS200A Work safely.

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.

Required Skills and Knowledge

This describes the essential skills and knowledge and their level, required for this unit.

Required skills

efficient and effective operation of plant/equipment

hazard analysis

completing plant records

communication

problem solving.

Required knowledge

A comprehensive understanding of separation equipment principles and typical problems to a level needed to control the operation, and recognise and resolve operational problems. In particular it includes a knowledge of:

principles of operation of plant/equipment

physics and chemistry relevant to the process unit, including kinetic energy effects

process parameters and limits, eg temperature, pressure, flow, pH

duty of care obligations

hierarchy of control

communication protocols, eg radio, phone, computer, paper, permissions/authorities

routine problems, faults and their resolution

relevant alarms and actions

plant process idiosyncrasies

correct methods of starting, stopping, operating and controlling flow

causes of head loss in piping systems, including comparison of fittings using Le/d concept, fluid and pipe material properties, flow geometry etc

corrective action appropriate to the problem cause

types and causes of separator problems within operator's scope of skill level and responsibility.

factors affecting efficient operation of the separation equipment

behaviour of solids, liquids and gases

function and troubleshooting of major internal components and their problems, such as internals, supports, nozzles, grids or scrapers

typical problems with separation equipment and their remedy

typical problems with drivers of separation equipment and their remedy.

Range Statement

The Range Statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the Performance Criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts.

Codes of practice/ standards

Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.

Equipment

Separation equipment covered by this competency includes all types of powered separation equipment for gaseous, liquid and solids separation duties, such as:

centrifuges

rotary dryers

rotary vacuum filters.

Problems

This competency covers electric motor drivers; however, other types of drivers may be included.

Typical problems include:

seal/gasket leaks

pressure loss/low flow

blockages/build-up

erosion/wear

separator driver problems.

Variables

The operator is required to monitor critical variables such as amps, temperature and vibration as well monitoring the output from the separation equipment.

Remedial actions

Remedial actions could include:

making adjustments to the equipment (flow, pressure, etc)

carrying out minor maintenance within operator's skill level

identifying and reporting problems outside operator's scope of ability

identifying and controlling hazards related to powered separation equipment and surrounding areas.

Start up shut down as required

Start up shut down as required includes:

start up and shut down to/from normal operating conditions

start up and shut down to/from isolated, cold, empty

all other conditions experienced on the plant.

ie from any condition to any condition experienced on the plant.

Appropriate action

Appropriate action includes:

determining problems needing action

determining possible fault causes

rectifying problem using appropriate solution within area of responsibility

following through items initiated until final resolution has occurred

reporting problems outside area of responsibility to designated person.

Procedures

Procedures may be written, verbal, computer-based or in some other form. They include:

all work instructions

standard operating procedures

formulas/recipes

batch sheets

temporary instructions

any similar instructions provided for the smooth running of the plant.

For the purposes of this Training Package, 'procedures' also includes good operating practice as may be defined by industry codes of practice (eg Responsible Care) and government regulations.

Health, safety and environment (HSE)

All operations to which this unit applies are subject to stringent health, safety and environment requirements, which may be imposed through State or Federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence.
