(2) In assessing whether the processing of a CSS is high risk, the person must have regard to the following: (a) the specific processing that will be undertaken; (b) the form or forms of crystalline silica present in the CSS; (c) the proportion of crystalline silica contained in the CSS, determined as a weight/weight (w/w) concentration; (d) the hazards associated with the work, including the likely frequency and duration that a person will be exposed to respirable crystalline silica;
