Respirable crystalline silica (RCS) is a known hazard generated when manipulating products and materials containing silica that can lead to lung cancer, silicosis, chronic obstructive pulmonary disease and kidney disease. It is estimated that 230 people a year will develop lung cancer due to past exposure. This risk is predominantly born by construction workers, alongside miners, farmers, and engineers. Recent years have seen a notable rise in silica-related illness and death, particularly evident in Queensland and linked to an increase of engineered stone. It is estimated that in 2011, approximately 587,000 Australians were exposed to silica dust whilst working, and that 5758 will eventually develop lung cancer. Workers in engineered stone benchtop manufacturing, finishing and installation are at particular risk, as this comparatively new material contains up to 95% crystalline silica, as distinct from natural stone’s crystalline silica composition of 5%-50%. The focus of the Silica Safety project is to develop appropriate occupational standards to meet the particular risks posed by RCS in building and construction.

Minimising the risk of respirable crystalline silica in the construction industry is an issue of national importance. The Construction, Plumbing and Services Industry Reference Committee (IRC) has been developing five units of competency to support skills and knowledge advancement to minimise the risks.

Online briefing

We are holding an online briefing for the Silica Safety project on the 29th of September, between 1:30-2pm. You can register for this session here.

Consultation and feeback opportunity

The Round 1 Consultation for the Silica Safety Project has been extended until the 30th September 2021, to ensure we receive the widest range of feedback possible.

Please download and read the draft units of competency available under the downloads section below, then provide feedback through either the Feedback tab or the consultation link. On an issue so important it's essential that we receive as much input as possible, from the widest range of stakeholders, to ensure that all safety concerns are addressed.

Under guidance from the Construction Industry Reference Committee, a working group has developed 5 draft units of competency, ranging from awareness to management. The draft units of competency aim to cover a range of scenarios from the prevention, early identification, control and management of products and materials containing crystalline silica.

The following table summarises the approach taken to date and provides an overview of the intended learner outcomes:

Unit code Unit title Learning outcome
CPCSIL1001 Prepare to work safely with products and materials containing crystalline silica

Demonstrate basic knowledge of silica safety.

This is a knowledge and awareness unit.

At this level, a person undertaking the unit is not working with silica products.

CPCSIL2001 Use and maintain respiratory protective equipment

Demonstrate competence using and maintaining respiratory protective equipment.

The unit covers the planning considerations prior to using RPE, fit checking, compliant use requirements and maintenance of RPE.

The unit is suitable for people who will be working with products containing crystalline silica and using RPE.

CPCSIL3001 Work with products and materials containing crystalline silica

Demonstrate competence in working safely with products containing crystalline silica.

This unit is suitable for people who will be working with products containing crystalline silica across a range of work environments.

CPCSIL4001 Supervise work with products and materials containing respirable crystalline silica

Demonstrate competence supervising work with respirable crystalline silica (RCS).

This unit is suitable for persons conducting a business or undertaking (PCBU), supervisors and managers responsible for ensuring the health and safety of employees, contractors and sub-contractors and suppliers when working with products containing crystalline silica.

CPCSIL5001 Manage risks of respirable crystalline silica

Demonstrate competence managing risks of respirable crystalline silica.

This unit of competency specifies the outcomes required to manage risks of exposure to RCS by the PCBU. The unit includes planning for compliant use of respirable protective equipment (RPE), PPE and plant, tools and equipment when managing worksites with products containing crystalline silica.
