Verification of Competency (Water Blaster (High Pressure))

Purpose of the Verification of Competency (Water Blaster (High Pressure))

High-pressure water blasters are powerful tools that pose significant risks, including fluid injection injuries, lacerations, slips, and exposure to hazardous noise levels. A Verification of Competency (VOC) is a formal process used to confirm that a worker has the necessary skills, knowledge, and experience to operate this equipment safely and effectively.

This document provides a structured framework for assessing an individual's ability to identify hazards, apply control measures, and perform operational tasks according to your organisation's procedures and Australian WHS best practices.

Conducting a VOC helps a Person Conducting a Business or Undertaking (PCBU) meet their primary duty of care. It is a critical component in ensuring that high-risk work is only performed by competent personnel.

Integrating this process into your safety framework demonstrates a commitment to proactive risk management. A robust VOC program is a cornerstone of effective WHS management systems, helping to prevent incidents before they occur.

How to use the Verification of Competency (Water Blaster (High Pressure))

This template is designed to be used by a competent assessor to evaluate a water blaster operator. The process should involve both a theoretical and a practical component.

The assessor asks the operator a series of questions to gauge their understanding of safety procedures, equipment features, and emergency responses. Following this, the assessor observes the operator performing a range of tasks, from pre-start checks and setup to operation and shutdown, assessing their practical skills against a set of established criteria.

Please note: this document is a template. We have designed it as a starting point, but you must customise it to reflect the specific water blaster models (e.g., Class A or Class B), pressure ratings, tasks, and hazards found in your workplace.

This may include adding criteria related to specific nozzles, accessories, or work environments. For other plant-specific assessments, you might find our Verification of Competency for a concrete or floor saw a useful reference.

When to use it

A Verification of Competency should be conducted at several key points to ensure ongoing safety and compliance. It is not a one-time event. Consider using this VOC process in the following situations:

• Pre-employment: To verify the skills and claims of a new hire before they commence work.
• Introduction of new equipment: When a new make or model of water blaster is introduced to the workplace.
• Post-training: To confirm that skills and knowledge from a training course have been successfully transferred to the workplace context.
• Following an incident: After a near-miss or incident involving a water blaster to identify and close any competency gaps.
• Periodic re-assessment: As part of a scheduled competency review program (e.g., annually or every two years) to ensure skills have been maintained.

Regularly scheduled assessments form a key part of a company's safety assurance activities. These activities are often reviewed during WHS compliance auditing to verify that the organisation is actively managing worker competency for high-risk tasks.

Who should use it

This template is intended for use by individuals responsible for workplace safety and operational supervision. This includes WHS Advisors, Safety Managers, Site Supervisors, and Team Leaders.

The person conducting the assessment (the assessor) must be competent themselves. This means they must possess deep technical knowledge of high-pressure water blasting, extensive practical experience, and a thorough understanding of the associated hazards and control measures.

The assessor should also have the skills to conduct an assessment fairly and objectively, provide constructive feedback, and clearly document the outcomes. They act as a subject matter expert, capable of making a reliable judgement on the operator's competence. Similar principles apply when assessing operators of other industrial equipment, as outlined in resources like our plasma cutter VOC template.

This VOC is just one of many tools available to help manage plant and equipment safety. For more templates and guides on a wide range of topics, explore our complete free WHS resources library.
