GUIDANCE ON THE INTERPRETATION OF WORKPLACE EXPOSURE STANDARDS FOR AIRBORNE CONTAMINANTS 213 Exposure measurement must not be used as an alternative to controlling exposure by putting in place hazard controls. Air monitoring is best done after control measures have been put in place. Compliance with the WHS legislation will require being able to

Protection of workers against animals, plants or several aspects of the environment with exposure to biological hazards must be used in the workplace. Measures should be taken to prevent risks of exposure to biological agents and hazards or, where this is not reasonably practicable, to reduce the risk of exposure to an acceptable level.

However, hazards are associated exposure with processing, including the fabrication workshop and upon installing and removing/demolishing slabs. Operations such as cutting, drilling, sawing, routing, grinding, chipping, polishing, sanding etc. can generate dust, and adequate ventilation and wet processes are recommended to keep exposure

Respirable Crystalline Silica (RCS) is found in stone dust and causes silicosis, cancer and chronic obstructive pulmonary disease (COPD).
