Required Skills

Required skills include

Ability to

read and interpret technical documentation and drawingsgraphics

inerpret material safety data sheets MSDS

interpret test results eg for atmospheregas 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 deenergised and isolated

hierarchy of isolations

methods of proving isolations

methods and equipment used for purging and ventilation

physical properties of process materials eg density and viscosity

hazardous properties of relevant materials eg 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 hangup in pipework the importance of identifying high point vents to release gasvapours and low point drains to release liquids

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

the potential effects eg damage to tanks or vessels of vacuum by not draining correctly eg by pulling a vacuum behind a slug of liquid

Evidence Required

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

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 adjusting pressure (usually to atmospheric) ensuring adequate access and egress
Isolation plan	Execution of the isolation plan may include, but is not limited to: confirming availability of plant, equipment and/or systems verifying plant, equipment and/or systems verifying isolation location securing and identifying isolation points labelling isolation points doing the isolations managing the isolations managing lock out/tag out to procedure cross checking isolations undertaking self-isolation, were appropriate
Remove materials and energy	Removing materials and energy may include, but is not limited to: draining, purging and venting of process materials mitigation of stored energy appropriately catching and disposing of any removed materials
Effectiveness of isolation	Proving the effectiveness of the isolation may include, but will not be limited to: checking that any leaks are acceptable proving depressuring proving purging checking bleed from double block and bleed, where appropriate proving the atmosphere is as required using gas detectors/meters proving the isolation is effective surveillance of isolations
Required paperwork	Required paperwork may include, but is not limited to: isolation register lock out/tag out register required reports required permits/work packs filing of documentation Paperwork will conform to the site requirements and document control systems Paperwork may be: paper, electronic or other approved form
Test as required	Testing of plant as required as part of preparation for return to service may include, but is not limited to: pressure and leak testing atmosphere/gas testing testing the restoration of utilities and services
