The unit applies to the preparation of dye mix, loading fabrics or yarn, operations, monitoring and unloading of materials in a dye house. Dyeing may be conducted at the raw material stage before spinning, weaving or knitting, at the hanking stage after yarn has been spun or at the final fabric production stage.

Work is conducted according to defined procedures.

Work may be conducted in small to large scale enterprises and may involve individual and team activities.

The application of this unit is according to OHS practices of the enterprise and workplace practices, which may include:

requirements prescribed by legislation, awards, agreements and conditions of employment

standard operating procedures

work instructions

oral, written and visual communication

quality practices, including responsibility for maintenance of own work quality and contribution to quality improvement of team or section output

housekeeping

tasks related to environmental protection, waste disposal, pollution control, and recycling

This unit requires the application of skills associated with planning and organising for the safe and efficient use of dyeing machines. This unit also requires the ability to check the quality of outcomes, identify and communicate inconsistencies or other problems and complete workplace documentation. Self management skills are applied to ensure workplace and quality standards are achieved.
