Select, operate and maintain scarifying equipment

This unit covers the competency to use scarifying equipment in applications relating to floor preparation.

Application

This unit supports the attainment of skills and knowledge required for competent workplace performance in the wide variety of sub-floor preparation operations. The competency applies to an on site environment and involves application of skills and knowledge at a sub-trade worker level. These skills and knowledge are to be used within the scope of the individual's job and authority.

Required Skills

Required skills

communicate ideas and information to enable confirmation of work requirements and specifications and the reporting of faults and problems

collect and understand information related to the use and maintenance of scarifying equipment

work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity

use pre-checking and inspection techniques to anticipate scarifying problems to avoid rework and wastage

recognise and respond to circumstances outside instructions or personal competence

plan and organise activities, including the preparation and layout of the worksite and the obtaining of tools

use mathematical ideas and techniques to correctly complete measurements and estimate other material requirements

clarify and confirm work instructions

plan work within given task parameters

accept responsibility for given tasks

set, monitor and satisfy personal work goals

satisfy the competency requirements for the job

maintain current knowledge of:

tools and materials

installation techniques

seek learning opportunities

use workplace technology related to the use and operator maintenance of scarifying equipment and associated materials

Required knowledge

State or Territory OHS legislation, regulations, standards and codes of practice relevant to the use of scarifying equipment

organisational and site standards, requirements, policies and procedures for preparing and presenting design information for the use of hand and power tools

types of scarifier attachments, their uses, capabilities and maintenance requirements

characteristics, uses and limitations of the available shot sizes

environmental protection requirements

established communication channels and protocols

problem identification and resolution

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.

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

Comply with legislation, regulations, standards, codes of practice and established safe practices and procedures for operating and maintaining scarifying equipment

Apply safe handling practices for equipment, products and materials

Adopt and carry out correct procedures prior to and during use of the scarifying equipment prescribed above in the Range Statement

Follow work instructions, operating procedures and inspection practices to:

prevent damage to goods, equipment and products

maintain required production output and product quality

minimise the risk of injury to self and others

Scarify a concrete sub-floor of a minimum of 10 sgm to industry standards

Smooth a concrete sub-floor using single headed, double headed and planetary action grinders correctly and safely to the relevant Australian Standard

Complete operator maintenance on scarifying equipment

Work effectively with others

Modify activities to cater for variations in workplace contexts and environment

Context of, and specific resources for assessment

The application of competency is to be assessed in the workplace or realistically simulated workplace.

Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints

Assessment of essential underpinning knowledge, other than confirmatory questions, will usually be conducted in an off-site context

Assessment is to comply with relevant regulatory or Australian Standards requirements

The following resources should be made available:

workplace location or simulated workplace

access to scarifying equipment and attachments

access to manufacturer/user instructions and/or manuals

Method of assessment

Assessment must satisfy the endorsed assessment guidelines of the Furnishing Industry Training Package

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application

Assessment may be applied under project related conditions (real or simulated) and require evidence of process

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances

Assessment may be in conjunction with assessment of other units of competency


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.
