You will need this licence to operate a business that undertakes an engineered stone process.
An engineered stone process is a process involving engineered stone at a workplace that generates crystalline silica dust. This includes cutting, grinding or abrasive polishing of engineered stone. Without appropriate control measures in place, exposure to dust containing crystalline silica can lead to diseases like silicosis.
You will also need this licence to purchase engineered stone from a supplier or manufacturer if you intend to undertake an engineered stone process.
