Performance Evidence

A person demonstrating competency in this unit must satisfy the requirements of the elements, performance criteria, foundation skills and range of conditions of this unit.

The person must also clean three different glass surfaces, including:

one ordinary glass (including mirror) or frosted glass surface measuring at least 1.5 metres in height or length, in which the work must involve:

selecting and using required cleaning equipment, including a squeegee

spot cleaning the glass

removing smears and drips from the glass and surrounding surfaces and floor

one textured glass surface, in which the work must involve:

selecting and using required cleaning equipment

spot cleaning the glass

conducting full clean of the glass to remove all soil

removing smears and drips from the glass and surrounding surfaces and floor

one ordinary frosted or textured glass surface, in which the work must involve:

removing three different inorganic soils from the glass surface using required cleaning techniques, one of which must require use of the scraping technique

selecting and using required cleaning equipment.

In doing the above work, the person must:

identify and plan for work site hazards

identify types and characteristics of glass surfaces and select cleaning equipment and chemicals required for the task

use safe and efficient cleaning techniques

correctly and safely handle waste, including contaminated materials.
