2.6 Toxicity Data
Not listed as a carcinogen by NTP and OSHA. A single case of allergic dermatitis has been reported after repeated skin contact. A single case of anaphylaxis was reported after ingestion. Reported to cause rabbit eye irritation after exposure to dust. Low order of acute oral toxicity based on acute and chronic stidues in several species. Not mutagenic in Ames assay or chromosone aberration test.
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.
Burns if heated, similar to wood. Chars readily on heating above 300 deg C. May form flammable dust air mixtures.
SAFE HANDLING INFORMATION
4.1 Storage / Transport
Ground all equipment. Blanket vessel with inert gas when emptying bags where flammable vapours may be present. Ground operator and pour material slowly into conductive, grounded chute. For large bags, a ground cable must be attached to the bag ground connection. Store in a cool, dry, well ventilated place. Keep container closed when not in use. Keep away from heat, flame, sparks and other ignition sources. Do not store in direct sunlight or expose to UV radiation.

4.3 Spills and Disposal
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.
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
Fire / Explosion
Avoid conditions that generate dust. This product may form flammable dust-air mixtures. Avoid emptying package in or near flammable vapours. Static charge may cause flash fire. If heated to decomposition, the following substabces may be formed: carbon monoxide, carbon dioxide, and smoke.
Firefighters should wear full portective clothing including self contained breathing apparatus. Use water spray, dry chemical, foam, carbon dioxide or halon as extinguishing media.
5 OTHER INFORMATION
Acute aquatic 96 hr static LC50 value falls within the practically nontoxic range of 100-1000 mg/l according to the US Fish and Wildlife criteria. Rainbow' trout and Bluegill were the species tested. The product is biodegradable.
