Unit Descriptor

Unit descriptor 

This unit of competency covers the skills and knowledge required to perform pressure washing to clean surfaces. Pressure washing produces a variable stream of either water or cleaning chemical and is used as a replacement for hand scrubbing in large areas or where the surfaces are very soiled. In this unit work is conducted from ground level. This unit is associated with PRMCL36B Clean at high levels, where work is conducted over two metres above ground level. Some surfaces, such as cracked, painted or other sealed surfaces, may be sensitive to pressure washing.

The unit requires the ability to assess the extent of the cleaning task through a knowledge of the characteristics of the surface area and the type of surface soiling, and applying an understanding of client requirements and company policies and procedures in order to perform the task. The work may be performed in teams or individually. The selection of appropriate equipment, chemicals and cleaning methods is essential for performing the task safely and efficiently.
