3. Hazard Identification
Appearance and Odor: The product is odorless, rolled, white paper.
Primary Health Hazards: The primary health hazard posed by this product is thought to be due to
exposure to dust.
Primary Route(s) of Exposure:
Ingestion:
Skin:
Inhalation: Dust
Eye:
Medical Conditions Generally Aggravated by Exposure: Cellulose dust may aggravate pre-existing
respiratory conditions or allergies.
Signs and Symptoms of Exposure:
Acute Health Hazards: Dust may be a mechanical irritant to the eyes.
Chronic Health Hazards: Paper (cellulose) dust is a biologically inert dust that has little or no effect on the
lungs and does not produce significant organic disease or toxic effect when allowable exposure limits
are met.

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.
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.

5. Fire and Explosion Data
Flash Point (Method Used): NAP
LFL = See below under 鈥淯nusual Fire and Explosion Hazards鈥? UFL = NAP
Flammable Limits:
Extinguishing Media: Water.
Autoignition Temperature: 450oF (232oC)
Special Firefighting Procedures: None.
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.

11. Toxicological Information
Toxicity Data: None available for product in purchased form. Individual component information is listed
below if available.
Components:
Cellulose: LC50 (rats, inhalation) = 5,800 mg/m3/4 hours.
Calcium carbonate: Applied to rabbit eyes with no toxic effects noted (concentration and exposure
duration not specified). Rats exposed to 81.2 mg/m3 for 90 minutes were sacrificed 1 hour and 21
hours after exposure; no pathologic effects were noted.

Safety and Health (provided by Canadian Centre for Occupational Health and Safety, CCINFO August
1995); Lewis, R.J., Sr. 1992, Sax鈥檚 Dangerous Properties of Industrial Materials, Eighth Edition, Van
Nostrand Reinhold, NY.
12. Ecological Information
Environmental Fate: Cellulose fiber slowly biodegrades in water (half life range 1mo 鈥? 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. It is, however, the user鈥檚 responsibility to determine at the time of disposal whether your
product meets EPA RCRA criteria for hazardous waste. Dispose in accordance with federal, state,
and local regulations.
