3. Hazard Identification
Appearance and Odor: The products are curtain coated boxes with little or no odor.
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:
(X) Inhalation: Dust
Medical Conditions Generally Aggravated by Exposure: Cellulose dust may aggravate
preexisting respiratory conditions or allergies.

3. Hazard Identification (cont.)
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.
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.
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
Flammable Limits:
LEL: See below under 鈥淯nusual Fire and Explosion Hazards鈥?
UEL: NAP
Extinguishing Media: Water.
Autoignition Temperature: 392掳-410掳F (200掳-210掳C)
Special Firefighting Procedures: None.
Unusual Fire and Explosion Hazards: Depending on moisture content, particle diameter, and
rate of heating, cellulose dust may explode in the presence of an ignition source. An airborne
3
concentration of 30,000 mg/m is often used as the LEL for cellulose pulp.
6. Accidental Release Measures
Steps to be Taken In Case Material Is Released or Spilled: Not applicable for product in
purchased form. Sweep or vacuum paper dust for recovery or disposal. Avoid dusty conditions
and provide adequate ventilation. Minimize compressed air blowdown or other practices that
generate high dust levels. Use NIOSH/MSHA approved dust respirator and goggles where
ventilation is not possible and exposure limits may be exceeded.
7. Handling and Storage
Precautions to be Taken In Handling and Storage: No special handling precautions are
required. Keep in cool, dry place away from open flame.

8. Exposure Control Measures
Personal Protective Equipment:
RESPIRATORY PROTECTION -- Not applicable for product in purchased form. A
NIOSH/MSHA-approved dust respirator is recommended when allowable exposure limits
may be exceeded.
PROTECTIVE GLOVES -- Not applicable for product in purchased form. However, cloth,
canvas, or leather gloves are recommended to minimize potential mechanical irritation
from handling product.
EYE PROTECTION -- Not applicable for product in purchased form. However, goggles or
safety glasses are recommended if the product is used in such a way as to generate high
dust levels.
OTHER PROTECTIVE CLOTHING OR EQUIPMENT -- Not applicable for product in
purchased form. Outer garments may be desirable in extremely dusty areas.
WORK/HYGIENE PRACTICES -- Not applicable for product in purchased form.
Ventilation:
LOCAL EXHAUST -- Provide local exhaust as needed so that exposure limits are met.
MECHANICAL (GENERAL) -- Provide general ventilation in processing and storage areas
so that exposure limits are met.
SPECIAL -- None.
OTHER -- None.
