3. Hazard Identification
Appearance and Odor: Rejects 鈥? Gray, fibrous mass with or without plastic and metal having a slight
paper odor. Pulper tail 鈥? Plastics, metal and other scrap material wound together.
Primary Health Hazards: The primary health hazards posed by this product are thought to be due to
exposure to dust (when product is dry).
Primary Route(s) of Exposure:
Ingestion:
鈱? Skin: Dust, fiber, water, organics, glass chips
鈱? Inhalation: Dust
鈱? Eye: Dust
Medical Conditions Generally Aggravated by Exposure: Cellulose dust may aggravate pre-existing
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鈥檇.)
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: Cellulose dust of certain species can elicit allergic contact dermatitis in sensitized
individuals, as well as mechanical irritation resulting in erythema and hives. Some debris is sharp-
edged and could cause shallow cuts or slivers. Get medical help if rash, irritation, or dermatitis
persists. Use appropriate first aid for cuts and slivers.
Inhalation: Excessive dust concentrations may cause unpleasant deposit or obstruction in the nasal
passages, resulting in dryness of nose, dry cough, and headaches. Remove to fresh air. Get
medical help if persistent irritation, severe coughing or breathing difficulty occurs.
Note to Physician: None

Extinguishing Media: Water
Autoignition Temperature: 400掳 - 500掳F (204掳 - 260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 concentration
of 30,000 mg/m3 is often used as the LEL for cellulose pulp.
