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

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

Critical aspects for assessment and evidence are:

tyre injury is identified and appropriate action determined

consistent application of inspection and testing standards

safety procedures are always followed.

Context of and specific resources for assessment

Assessment will occur on an HOTR tyre repair facility. 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.

Method of assessment

Competence in this unit may be assessed:

by observation over a range of tyre inspection procedures undertaken in the workplace

in a situation allowing for the generation of evidence of the ability to 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 appropriate practical/simulation assessment will be combined with targeted questioning to assess the required knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment.

Guidance information for assessment

Assessment processes and techniques must be appropriate to the language, competency and safety requirements of the site and consistent with workplace systems or procedures.

Required skills

Required skills include:

use of inspection tools

communicating effectively

analytical skills

working safely in accordance with operational requirements and safe systems of work

ability to read and interpret typical product specifications, job sheets and material labels as provided to operators

writing to the level of completing workplace forms and production reports

Required knowledge

Required knowledge includes:

organisation’s procedures

heavy off-the-road (HOTR) tyre construction

radial and bias ply construction

methods of identifying lug/position identification

AS 4457.2-2008 Earth-moving machinery - Off-the-road wheels, rims and tyres - Maintenance and repair - Tyres

hazards and hazard controls associated with HOTR tyre inspection

indicators of tyre injuries

injuries which do not need repairing, injuries which are reparable and injuries which either individually or in the sum should not be repaired

reporting procedures

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.

Initial documentation

Completing initial documentation will include ensuring that:

the serial number is correct

the correct tyre is inspected

Injuries to tyres

Injuries to tyres may include, but are not limited to:

cuts, abrasion, splits, cracks and crazing

separations within the structure

deformities both surface and internal

penetrations into and through the casing/carcass

Injuries

Injuries may include, but are not limited to:

injuries which do not need repair and should be returned to the customer to be used as is

injuries which should be repaired

injuries which are beyond repair and so the tyre should be scrapped

Standards

Standards may include, but are not limited to:

AS 4457.2-2008 Earth-moving machinery - Off-the-road wheels, rims and tyres - Maintenance and repair – Tyres

Rubber Manufacturer’s Association of America (RMA)

Supplier standards, such as technical data sheets and manuals

internal organisational standards

Procedures

Procedures may be written, verbal, computer-based or in some other form. They may include, but are not limited to:

all work instructions

standard operating procedures

formulas/recipes

batch sheets

temporary instructions

any similar instructions provided for the smooth running of the plant

good operating practice as may be defined by industry codes of practice

Procedures would be expected to comply with any relevant government regulations.

Paperwork

Paperwork may be paper or electronic-based.

Appropriate action

Appropriate action includes, but is not limited to:

determining problems needing action

accessing and applying relevant technical and plant data

applying appropriate problem solving techniques to determine possible fault causes, within manufacturer guidelines and safety procedures

rectifying problem using appropriate solution within area of responsibility

following through items initiated until final resolution has occurred

reporting problems outside area of responsibility/ability to designated person

Health, safety and environment (HSE)

All operations to which this unit applies are subject to stringent HSE 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.
