Use fire fighting procedures suitable for surrounding area. Fire/Explosion Hazard Solid which exhibits difficult combustion or is difficult to ignite. Avoid generating dust, particularly clouds of dust in a confined or unventilated space as dusts may form an explosive mixture with air, and any source of ignition, i.e. flame or spark, will cause fire or explosion. Dust clouds generated by the fine grinding of the solid are a particular hazard; accumulations of fine dust (420 micron or less) may burn rapidly and fiercely if ignited; once initiated larger particles up to 1400 microns diameter will contribute to the propagation of an explosion. A dust explosion may release large quantities of gaseous products; this in turn creates a subsequent pressure rise of explosive force capable of damaging plant and buildings and injuring people. SECTION 6 ACCIDENTAL RELEASE MEASURES Personal precautions, protective equipment and emergency procedures Minor Spills Remove all ignition sources. Clean up all spills immediately. Avoid contact with skin and eyes. Control personal contact with the substance, by using protective equipment. Major Spills Moderate hazard. CAUTION : Advise personnel in area. Alert Emergency Services and tell them location and nature of hazard. Control personal contact by wearing protective clothing. Personal Protective Equipment advice is contained in Section 8 of the MSDS. SECTION 7 HANDLING AND STORAGE Precautions for safe handling Safe handling Hazard relates to dust released by cutting, grinding, trimming or other shaping operations. Avoid generating and breathing dust Avoid contact with skin and eyes. Wear nominated personal protective equipment when handling. Use in a well-ventilated area. Other information Store in original containers. Keep containers securely sealed. Store in a cool, dry, well-ventilated area. Store away from incompatible materials and foodstuff containers. Conditions for safe storage, including any incompatibilities Suitable container Polyethylene or polypropylene container. Check all containers are clearly labelled and free from leaks.

Because the margin of safety of the quartz TLV is not known with certainty and given the associated link between silicosis and lung cancer it is recommended that quartz concentrations be maintained Chemwatch: 22-9931 Version No: 5.1.1.1 Page 3 of 7 EssaStone Issue Date: 11/03/2014 Print Date: 15/06/2014 Continued...
