Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and under supervision demonstrate the ability to:
assemble and operate equipment which meets the requirements of a Class B system as defined by AS/NZS 4233.1:2013 High pressure water jetting systems - Safe operation and maintenance or its authorised replacement, including:
at least one (1) gun operation AND
at least one (1) of:
pipe cleaning
heat exchanger/tube cleaning
surface preparation
vessel (interior) cleaning using a cleaning head AND
use at least two (2) different types of nozzles/heads.
Must provide evidence that demonstrates knowledge relevant to their job sufficient to operate under routine only supervision and to solve routine problems, including:
system controls required by AS/NZS 4233.1: 2013 High pressure water jetting systems - Safe operation and maintenance, or its authorised replacement
possible injuries resulting from high pressure water jets and appropriate responses
basic principles of how high pressure water jetting nozzles/jets work
basic understanding of reaction force and its determination
preoperational checks and set-up
relevant communication systems, including hand signals
types of waste generated and procedures for safe disposal.
Competency must be achieved before performing this work under supervision. Therefore this unit will typically be assessed off the job. Where assessment is undertaken on the job appropriate supervision and safety precautions must be provided.
The unit should be assessed holistically and the judgement of competence shall be based on a holistic assessment of the evidence.
While water jetting equipment meeting the requirements of Class B must be used, the plant/job requiring water jetting may be a realistic simulation of an industry plant/application/situation.
All appropriate tools, equipment, paper work/permits and safety gear required will be available and used as required. The assessor should act as the supervisor, giving such directions as would be provided on the job. It is expected that one assessor would not observe a group larger than ten persons at the one assessment event.
Off-the-job assessment must sufficiently reflect realistic operational workplace conditions that cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
Assessment in a simulated environment should use evidence collected from one or more of:
walk-throughs
demonstration of skills
industry-based case studies/scenarios
‘what ifs’.
Knowledge evidence will be collected independently of the above practical assessment and may use workbooks, written assessments, interviews (provided a record is kept) or other methods.
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
Persons seeking verification of competence/retraining to comply with AS/NZS 4233.1:2013 High pressurewater jetting systems - Safe operation and maintenance, or its authorised replacement must meet the same evidence requirements as above.
The regulatory framework will be reflected in workplace policies and procedures and is not required to be independently assessed.
Foundation skills are integral to competent performance of the unit and should not be assessed separately.
As a minimum, assessors must satisfy the Standards for Registered Training Organisations 2015 assessor requirements.
