Start by identifying activities that produce dusts, vapours, fumes or biological contaminants. Then assess who may be exposed, how often, and whether controls like ventilation, LEV or PPE are in place.
Measurements or monitoring results can support the assessment, but they’re not always required. What matters is understanding where air quality may pose a risk and documenting how you’ll reduce that risk. Updating the assessment whenever work changes is also important, as new tasks may create new exposure concerns.
