Verification of Competency (Sand Blaster)

Purpose of the Verification of Competency (Sand Blaster)

The primary purpose of this Verification of Competency for sand blasters is to ensure workers have the current skills and knowledge to operate the equipment safely in your specific environment. Sand blasting presents severe risks, including exposure to hazardous dust (like respirable crystalline silica), high-pressure injection injuries, noise-induced hearing loss, and hazards from the plant itself.

A VOC goes beyond a simple training certificate; it's a practical confirmation of ability. It helps a PCBU fulfil their primary duty of care by verifying that training has been understood and can be applied in real-world conditions. Documenting this process is a key component of demonstrating due diligence within your overall WHS management systems.

How to use the Verification of Competency (Sand Blaster)

This template should be used by a competent person—typically a supervisor, experienced operator, or safety advisor with extensive knowledge of sand blasting operations. The assessment should involve a combination of direct observation, verbal questioning, and a review of the operator's understanding of procedures.

The process generally includes:

• Theory and Knowledge: Asking questions about pre-start checks, hazard identification, emergency procedures, and the function of safety features like the dead-man switch.
• Practical Observation: Watching the operator carry out the entire task, from setting up the blast pot and hoses to performing the blasting and shutting down the equipment safely.
• Documentation: Recording the observations and outcomes on the checklist. If gaps in competency are identified, a plan for further training or supervision should be put in place and documented.

Please note: This document is a template and must be customised to your specific workplace. We have included common criteria, but you must assess your unique sand blasting equipment, abrasive media, work environment, and internal procedures.

Regular checks of your documented processes, such as those performed during WHS compliance auditing, ensure they remain effective and relevant to your operations.

When to use it

A VOC for sand blasting is not a one-time event. It should be conducted at various points to ensure skills remain current and relevant. Key triggers for conducting a VOC include:

• As part of a pre-employment or pre-contract engagement process.
• When a worker is assigned to use a new or different model of sand blaster.
• If a worker has not operated the equipment for a significant period.
• When observation or performance data suggests a worker may require refresher training.
• Following an incident or near-miss involving the equipment.
• As part of a scheduled periodic review, for example, every two years, to ensure ongoing competency.

Who should use it

This template is designed for use by PCBUs, managers, supervisors, and WHS professionals responsible for ensuring plant and operator safety. The person conducting the assessment must be deemed competent themselves.

This means they possess detailed knowledge of the sand blaster's operation, the associated hazards, and the control measures required. They must be able to make a valid and reliable judgement about another person's competency.

For high-risk tasks like this, it is not enough for the assessor to have simply read the manual; they need practical, hands-on experience.

Key Assessment Criteria for Sand Blaster Operators

A comprehensive VOC should cover all phases of the sand blasting task. While our template provides a detailed list, key areas for assessment must include the operator's ability to:

• Conduct thorough pre-start inspections of the blast pot, hoses, connections, nozzle, and safety devices.
• Select, inspect, and correctly don all required Personal Protective Equipment (PPE), including blast helmet, air supply, hearing protection, and protective clothing.
• Demonstrate correct setup of the work area, including barricading, signage, and containment measures if required.
• Safely load the abrasive media and pressurise the system.
• Maintain correct blasting technique, posture, and control of the dead-man switch at all times.
• Recognise and respond to equipment malfunctions or emergencies.
• Follow correct shutdown, depressurisation, and clean-up procedures.

The principles of verifying practical skill are transferable across various types of workplace plant. For example, our Verification of Competency (Plasma Cutter) template also focuses heavily on pre-start checks and the correct use of safety features specific to that equipment.

Similarly, assessing competency on equipment that generates dust and noise, like that covered in our Free Bench Grinder VOC (Verification of Competency) Template, shares a common focus on PPE and hazard control. Sandblasting often requires working at height or in awkward positions, making it crucial to assess the operator's awareness of their surroundings. In situations where access equipment is used, you may also need to complete a separate Verification of Competency (Boom Lift or Knuckle Boom) Template.
