3. PRECAUTIONS FOR USE


3.1 Exposure Standards

Occupational exposure standard : 5 mg/m3 - measurements of environmental dust have shown a significant respirable content, although due to the nature of the material, this is unlikely to present a serious problem.

3.2 Engineering Controls

Ensure adequate ventilation to maintain exposure levels below standards.

3.3 Personal Protection

Respiratory - respirator and/or dust masks are recommended when manually opening and emptying bags and sacks. Eyes - safety spectacles are recommended as minimum eye protection. Skin - protection is not normally required for skin contact. Wash hands and face thoroughly after handling and before work breaks, eating, drinking, smoking and using toilet facilities.

3.4 Flammability

Burns if heated, similar to wood. Chars readily on heating above 300 deg C. May form flammable dust air mixtures.


SAFE HANDLING INFORMATION

Spills

Clean up personnel should wear suitable protective clothing including respiratory protection if risk of inhalation of dusts. Avoid wetting spills, as surfaces can become very slippery.

Vacuum or sweep up material for use or disposal. Apply absorbent to wet spills and sweep up for disposal. After removal, flush contaminated area thoroughly with water.

Disposal

Incineration in accordance with applicable regulations is the recommended disposal method. Landfilling in a permitted solid or hazardous waste facility, meeting technical regulatory requirements is a suitablr alternative. Wastewater containing this product can be considered for treatment in an acclimated biological treatment system.

4.4 FIRE AND EXPLOSION HAZARD
