The national workplace exposure standard for respirable crystalline silica has been halved from an eight hour time-weighted average airborne concentration of 0.1 milligrams per cubic metre (mg/m3) to 0.05 mg/m3; this new workplace exposure standard takes effect in Queensland from 1 July 2020.

Silicosis is preventable by using proper controls to eliminate or minimise expo sure to respirable crystalline silica dust in the workplace.
