Elements and Performance Criteria

  1. Confirm repair specification
  2. Design installation process
  3. Prepare for installation
  4. Monitor installation

Range Statement

This field allows for 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.

Regulatory framework

The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used.

Applicable legislation, regulations, standards and codes of practice include:

HSE legislation, regulations and codes of practice relevant to the workplace, equipment and production processes and hazardous materials

Australian/international standards relevant to the materials being used and products being made

any relevant licence and certification requirements.

All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and such requirements the legislative requirements take precedence.

HSE hazards

Identification of HSE hazards requires consideration of:

exposure to heat

exposure to dust

exposure to refractory materials

confined space entry

working with equipment

working at heights

ultra-violet (UV) and other welding hazards

disposal of waste, scrap and excess materials

manual handling hazards.
