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 range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

This unit should be assessed as holistically as is practical and will generally be assessed using a workplace project as a significant assessment activity.

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

A person who demonstrates competency in this unit must be able to provide evidence of the ability to:

perform isolations to plan for a significant item of equipment or plant area

prepare plant for the work to plan

prepare plant for return to service to plan.

Context of and specific resources for assessment

Assessment of performance must be undertaken in a workplace.

Access may be required to:

workplace procedures and plans relevant to work area

specifications and documentation relating to planned work

documentation relating to the plant, process and materials

the isolation and preparation plan

any other materials which would normally be available in the workplace while conducting this activity.

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

Required skills include:

Ability to:

read and interpret technical documentation and drawings/graphics

inerpret material safety data sheets (MSDS)

interpret test results (e.g. for atmosphere/gas testing and leak testing)

Required knowledge includes:

Knowledge of:

work control system for site and organisation

existence of regulations and other external controls relevant to the proposed work

isolation philosophy of organisation

isolation and preparation plan for work

plant energy sources and their methods of being de-energised and isolated

hierarchy of isolations

methods of proving isolations

methods and equipment used for purging and ventilation

physical properties of process materials (e.g. density and viscosity)

hazardous properties of relevant materials (e.g. process, purging and ventilation materials)

decontamination methods and requirements for various materials and situations

as low as reasonably practicable (ALARP) concept

importance of appropriate rates of change for pressure and temperature for vessels and other plant

significance of time allowed for draining, purging, ventilation

fluid dynamics relating specifically to draining piping systems:

the ability of a liquid to ‘hang-up’ in pipework, the importance of identifying high point vents to release gas/vapours and low point drains to release liquids

determining the amount of liquid drained from a piping section to ascertain that draining has been effective/prove drainage

the potential effects (e.g. damage to tanks or vessels) of vacuum by not draining correctly (e.g. by pulling a vacuum behind a slug of liquid)

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. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Isolation

Isolation is a process for ensuring no energy or material can enter the isolated area

Plant energy sources

Plant energy sources may include, but are not limited to:

electricity (mains, solar and by generator)

chemicals and fuels

heat and steam

pneumatic pressure (compressed air, and other fluids under pressure, such as water or hydraulic oil)

energy storing devices, such as batteries, springs, flywheels, accumulators and capacitors

gravity (and its ability to cause items to fall)

radiation

Control releases

Controlling releases to the environment may include, but is not limited to:

preventing any release

containing any release

recovery and reuse or disposal of any release

Preparation

Preparation is a process for ensuring that plant and equipment is in a safe and appropriate condition for the required work. Preparation may include, but is not limited to:

draining

purging

inerting

ventilating

controlling atmosphere (e.g. to ensure it is breathable, and is not within the flammable range)

adjusting temperature to make a workable environment
