Unit of competency
Modification History
Release 1. Newly created unit.
Application
This unit describes the skills and knowledge required to autonomously operate a hydro excavation system which uses pressurised water and an industrial strength vacuum to simultaneously excavate soil. Work involves the safe removal of ground debris from underground infrastructure. This is a specific and limited application of the use of high pressure water jetting equipment.
This work is undertaken using a vacuum loading system and a high pressure water jetting system that meets the requirements of a Class B system as defined by AS 4233.1 High pressure water jetting systems – Part 1: Safe operation and maintenance, and in compliance with Safe Work Australia Guide for Managing Risks from High Pressure Water Jetting, its state/territory equivalent (where one exists) or the authorised replacement.
The worksite may be a client’s site, a site belonging to the organisation or a public space.
No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia, including refresher training, must be applied.
