Elements and Performance Criteria

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. Add any 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.
Where reference is made to industry codes of practice and/or Australian/international standards, the latest version must be used.
Context
This competency applies to the removal and replacement of conveyor belts. It includes the operation of all relevant additional equipment where that equipment is integral to the belt removal and replacement process. The competency unit includes the use of manual handling aids such hand winches and portable lifting gear, and of powered equipment/aids for some aspects.
Procedures
All operations are performed in accordance with procedures.
Procedures include all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards.
Tools and equipment
This competency covers different types of conveyor belts, including:
steel cord belts
fabric reinforced ply belts
solid woven belts.
The competency includes use of equipment and tools such as:
portable power generators and vulcanising equipment
knives and other cutting instruments
belt winders, belt stands and winches
clips, pulling plates, steel cables (certified as required)
portable hoists/lifting equipment not requiring any special permits or licences
hand tools (such as spanners, wrenches, hammers)
power operated hand tools (such as drills, cutting disks, sanders)
relevant personal protective equipment
Hazards
Typical hazards include:
unpredicted belt movements
equipment malfunctions
manual handling hazards
lifting, tracking and securing hazards
equipment operation hazards
damaged material hazards.
Problems
'Anticipate and solve problems' means resolve a wide range of routine and non-routine problems, using product and process knowledge to develop solutions to problems which do not have a known solution/a solution recorded in the procedures.
Typical process and product problems may include:
weight of the belting to be removed and replaced
obstructions and impediments to removal and fitting on new belt
worn or malfunctioning rollers, drums or propulsion equipment
lack of accessibility
lack of required human resources
tool problems
variations in materials and/or contamination of materials
processing problems.
Variables
Key variables to be monitored include:
belt condition
belt location
gradient of belt
types of scrapers
skirting systems used
degree of damage
weight of the belt
forces acting on the conveyor belt
environmental conditions
lock-out of equipment.

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 this training package.
Overview of assessment
A holistic approach should be taken to the assessment.
Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:
identify critical materials properties and belt removal and replacement process characteristics
identify hazards in the removal and replacement process and put in place appropriate controls
plan own work process within workplace procedures and explain the reasons for the steps in the process
take appropriate action to observe equipment, materials and products for out of specification results, make adjustments and identify problems to be reported.
Consistent performance should be demonstrated. For example, look to see that:
production quality and output standards are met consistently
problems are anticipated from process observations
problems are efficiently resolved
the removal and replacement process runs consistently and smoothly.
Assessment method and context
Assessment will occur in the field on an industrial conveyor belt installation.
Competence in this unit may be assessed:
on a processing plant, allowing for operation under all normal and a range of abnormal conditions
in a situation allowing for the generation of evidence of the ability to recognise, anticipate and respond to problems
by using a suitable simulation and/or a range of case studies/scenarios
through a combination of these techniques.
In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.
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.
Specific resources for assessment
This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
