About the licence

Engineered stone can have very high quantities of crystalline silica, which is released when the stone is cut, ground, drilled or abrasively polished. Without appropriate control measures in place, exposure to dust containing crystalline silica can lead to diseases like silicosis.

A licence is granted to a business (either an employer or self-employed person) to work with engineered stone if they meet the necessary safety requirements.

Installation work involving an engineered stone process can occur at another workplace, where it is necessary and not practical to do so at the licence holder's workplace.

Businesses in the stonemason industry are likely to need an engineered stone licence to conduct their business if it involves cutting, grinding and/or abrasively polishing engineered stone.

You will also need a licence to buy engineered stone from a supplier or manufacturer, if you intend to undertake an engineered stone process. This applies to purchases for your own business, or on behalf of a licenced business.

An engineered stone licence is valid for five years.

WorkSafe issues engineered stone licences in accordance with part 6.1 of the Occupational Health and Safety (OHS) Regulations 2017.

Planning for the new licence

The requirement to apply for an engineered stone licence came into effect on 15 November 2021.

A transition period until 14 November 2022 provides time to prepare a licence application. Applications for a new licence that are submitted by then will be free.

If you apply before 15 November 2022, and are granted a licence, the issue date will be 15 November 2022. Your licence will be valid for 5 years from this date.

Licence requirements must be met before a licence will be granted. As part of the licence application, a WorkSafe inspector may attend the workplace to verify licence requirements are met.

Penalties will apply to employers who work with engineered stone without a licence after 15 November 2022.

Engineered stone control plan (ESCP)

A licence is not required prior to 15 November 2022. However, employers and self-employed persons must prepare an ESCP in line with OHS Regulations before undertaking any work involving an engineered stone process.

Employers and self-employed persons must ensure the work is performed in line with the ESCP. They must also review, and if necessary revise the ESCP if the risk control measures are not adequately controlling the risks. This includes reviewing the ESCP after any incident involving engineered stone.

Safety obligations

During the transition period, safety obligations apply to undertaking an engineered stone process. Employed and self-employed persons must:

  • have an ESCP
  • comply with the specific measures in place to control the risks associated with engineered stone, contained in in Part 4.5, Division 3, Subdivision 3 of the Occupational Health and Safety Regulations 2017
  • comply with their existing duties under Part 4.1 of the Occupational Health and Safety Regulations 2017

Information, instruction and training

Employers are responsible for ensuring employees receive information, instruction and training before they start work at a location where an engineered stone process occurs. This needs to cover:

  • the health risks associated with exposure to crystalline silica dust
  • the need for and proper use of control measures required under the crystalline silica regulations
  • how the control measures are to be implemented. This includes for the use of a power tool or mechanical plant; and for the use, fit, maintenance and storage of respiratory protective equipment

Examples of this include training with the manufacturer on the equipment being used; instruction on the use, fit, maintenance and storage of respiratory protective equipment. Or documents such as training manuals, staff presentations or information sheets.

Employers also need to provide job applicants, and current employees undertaking an engineered stone process, information on:

  • the health risks associated with exposure to crystalline silica dust
  • the need for and details of control measures required under the crystalline silica regulations
  • how the control measures are to be implemented

Employees who don't receive information, instruction and training may not know how to work safely with engineered stone and crystalline silica. Employers who fail to provide these risk breaching their duties under the OHS Act and Regulations.
