3. Hazard Identification
Appearance and Odor: The products are odorless writing and printing papers.
Primary Health Hazards: The primary health hazard posed by these products 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.
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.

3. Hazard Identification (cont.)
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: 450oF (232oC)
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 concentration of
30,000 mg/m3 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 dust for recovery or disposal. 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 for
product in purchased form. 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.

8. Exposure Control Measures (cont.)
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.
