Roller VOC

Purpose of Document

Roller VOCs are used to verify a worker’s competence in Roller use. The primary goal is to protect workers from injury or illness through effective training and competency procedures. This form is broadly aligned with AS45001:2018.

How to Use

This Roller VOC should be completed by a competent person in consultation with the trainee who will use the plant. This document is a template only and should be customised for your business.

When to Use

Roller VOCs should be completed prior to the worker operating plant or equipment within your business.

Who Should Use

Roller VOCs must be completed by someone who is familiar with operation of the piece of plant or equipment. This person should also be competent in training and assessment methods.

Legal Considerations

There is no specific legal requirement to complete a documented Verification of Competency (VOC). However, it is best practice, especially for larger companies. It can help meet general legal duties, including:

  • s(19)(3)c WHS Act – Duty to Provide Safe Systems of Work
  • s(19)(3)d WHS Act – Duty to Ensure Safe Use of Plant
  • s(19)(3)f WHS Act – Duty to Provide Adequate Information, Training, Instruction and Supervision
  • s(203) WHS Regulations – Management of Risks to Health and Safety (PCBUs with management or control of plant)

The Code of Practice “Managing risks of plant in the workplace” states that employers (PCBUs) must ensure workers are trained and have the appropriate skills to carry out a particular task safely.


What is a roller?

A roller is a heavy machine used to compact soil, asphalt, or concrete by applying pressure with large cylindrical drums, creating a solid foundation for construction projects.

What is a roller used for?

A roller compacts soil, asphalt, or concrete during construction. Its large drum applies pressure to surfaces, increasing material density for solid foundations in roads and buildings. Rollers reduce air voids and improve compaction, essential in construction and road maintenance.

What hazards are involved in roller use?

Many hazards exist in roller operation, for example:

  • Roller overturning
  • Struck-by accidents
  • Pinching/crushing injuries
  • Falls
  • Collisions
  • Exposure to hazardous materials

To mitigate these hazards, similar measures to those used with backhoes are employed: proper training, adherence to safety protocols, regular equipment maintenance, use of personal protective equipment (PPE), and thorough site inspections.

Do you need a license to operate a roller?

Legally, you only require a license to operate “high-risk plant” (usually). For other types of plant or equipment, the level of training provided should be suitable considering “the nature of the work, the nature of the risks and the control measures required” – WHS regulations s(39). That is, for plant that poses no or minimal risks, there may be very little training required. As the risks of the plant increases, the requirement for training also increases.

To demonstrate competence in roller operation, workers can complete the RTO unit

Did You Know?

Rollers are widely used in Australia for various applications. These heavy machinery vehicles play a crucial role in the construction and road maintenance sectors across the country. Rollers are specifically designed to compact and flatten surfaces, ensuring the durability and stability of roads, highways, and other structures.

They come in different sizes and configurations to suit various project requirements. With their heavy drums or wheels, rollers provide efficient compaction of soil, asphalt, and other materials. In Australia, rollers are essential in creating sturdy and reliable infrastructure, contributing to the smooth and safe movement of vehicles and pedestrians.
