Carcinogenicity Listing: NTP: Not listed IARC Monographs: Not listed OSHA Regulated: Not listed 4. Emergency and First-Aid Procedures Ingestion: Not applicable for product in purchased form.

5 Eye Contact: Dust may mechanically irritate the eyes, resulting in redness or watering. Treat dust in eye as foreign object. Flush with water to remove dust particles. Get medical help if irritation persists. Skin Contact: Not applicable for product in purchased form. Skin Absorption: Not applicable for product in purchased form. Inhalation: Excessive dust concentrations may cause unpleasant obstruction in the nasal passages. Remove to fresh air. Get medical help if persistent irritation, severe coughing, or breathing difficulty occurs. Note to Physician: None. 5. Fire and Explosion Data Flash Point (Method Used): NAP Flammable Limits: LFL = See below under Unusual Fire and Explosion Hazards UFL =NAP Extinguishing Media: Water. Autoignition Temperature: 450oF (232oC) Special Firefighting Procedures: None.

6 Unusual Fire and Explosion Hazards: Depending on airborne concentration, moisture content, particle diameter and rate of heating, Cellulose dust may explode in the presence of an ignition source. An airborne concentration of 30,000 mg/m3 is often used as the LEL for Cellulose fibers. Reference NFPA Standards 654 and 664 for guidance.

Ecological Information Environmental Fate: Cellulose fiber slowly biodegrades in water (half life range 1mo 1 yr in freshwater and coastal seawater). Cellulose fiber persists in arid soil (landfills). Calcium carbonate dissociates in water, and the ions are widely found in natural waters. Alum dissociates in water. Environmental Toxicity: NAV 13. Disposal Considerations Waste Disposal Method: If disposed or discarded in purchased form, incineration or dry land disposal is acceptable.
