Elements and Performance Criteria

  1. Identify and prepare for work requirements
  2. Apply densifying or sealing system
  3. Complete housekeeping

Range Statement

Specifies different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Range is restricted to essential operating conditions and any other variables essential to the work environment.

Legislative requirements include:

applicable legislation from all levels of government that affect organisational operation

award and enterprise agreements

industrial relations

Australian Standards

confidentiality and privacy

work health and safety (WHS)

the environment

equal employment opportunity (EEO)

anti-discrimination

relevant industry codes of practice

duty of care and heritage

WHS requirements include:

Commonwealth, state or territory legislation and regulations

organisational safety policies and procedures

the use of personal protective equipment and clothing

firefighting equipment

first aid equipment

hazard and risk control and elimination

control of hazardous materials and substances

manual handling, including lifting and carrying

Organisational requirements include:

legal, organisational and site guidelines

policies and procedures relating to own role and responsibility

quality assurance

procedural manuals

quality and continuous improvement processes and standards

WHS

emergency and evacuation

ethical standards

recording and reporting

access and equity principles and practices

equipment use, maintenance and storage

environmental management (waste disposal, recycling and re-use guidelines)

Instructions include:

workplace procedures relating to the use and operation of tools and equipment

workplace instructions, including job sheets, plans, drawings and designs

workplace procedures relating to reporting and communications

manufacturer recommendations for the use of equipment and materials

Densifiers and sealers include:

reactive concrete densifiers using colloidal silica to harden and densify new or older concrete surfaces

densifiers and sealers protect concrete from stains, dust production and wear, and supports polishing

Application methods include:

pour and brush spreading

low-pressure, airless spraying

Surface inspection includes:

ensuring that surface is free from dust and debris, moisture content is acceptable and stable and any contaminants are adequately removed

Personal protective equipment includes:

that prescribed under legislation, regulation and enterprise policies and practices

isolation processes, including barriers, tapes and entry access controls, breathing support and ventilation extraction systems

Performance Evidence

Comply with legislation, regulations, standards, codes of practice and established safe practices and procedures for applying densifiers and sealers to concrete floors

Interpret work order and locate and apply relevant information

Apply safe handling requirements for equipment, products and materials, including the use of personal protective equipment

Establish and maintain appropriate ventilation

Follow work instructions, operating procedures and inspection practices to:

prevent damage to goods, equipment and products

minimise the risk of injury to self and others

Achieve a final densified and sealed finish in accordance with accepted industry practices

Complete application of densifying and sealing products to both new and older concrete surfaces

Modify activities to cater for variations in workplace contexts and environment

Identify any application faults/problems and identify and carry out corrective action

Communicate ideas and information to enable confirmation of work requirements and specifications, coordination of work with site supervisor, other workers and customers, and the reporting of work outcomes and problems

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 concrete surface problems to avoid re-work 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 equipment and materials to avoid any backtracking, work flow interruptions or wastage
