4. First Aid Measures
Inhalation: Excessive dust concentrations may cause unpleasant deposit or obstruction in the nasal
passages. Remove to fresh air. Seek medical help if persistent irritation, severe coughing or
breathing difficulty occurs.
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. Seek medical help if irritation persists.
Skin Contact: Not applicable for product in purchased form.
Skin Absorption: Not known to be absorbed through the skin.
Ingestion: Not applicable under normal use.
Symptoms or Effects:
Acute Symptoms/Effects – Cellulose dust can cause eye irritation and obstruction in the nasal passages.
Delayed Symptoms/Effects – NAP
5. Fire-fighting Measures
Extinguishing Media and Restrictions: Water or other extinguishing agents appropriate for fighting
surrounding fires.
Specific Hazards, Anticipated Combustion Products: Combustion products include carbon monoxide,
carbon dioxide and fine particulate in the form of smoke.
Autoignition Temperature: 450°F (232°C).
Special Firefighting Equipment/Procedures: As in any fire wear approved self contained breathing
apparatus and appropriate protective clothing.
Unusual Fire and Explosion Hazards: Pulp processing (e.g. fiberization) may result in the release of
cellulose fibers. Newsprint and Specialty Paper products in the form as supplied and shipped are
highly unlikely to release sufficient cellulose dust to constitute a combustible dust explosion hazard.
Depending on airborne concentration, moisture content, particle diameter, surface area and exposure
to an ignition source, airborne cellulose dust may ignite and burn with explosive force in a contained
area. Cellulose dust may similarly deflagrate (combustion without detonation like a supersonic
explosion) if ignited in an open or loosely contained area. Cellulose dust explosibility: (*Kst dry =
>200 and < 300 bar m/s). Caution should be taken in the processing, shipping, handling and use of
these materials, particularly if they are in a dry state and dust is produced. Reference NFPA
standards 654, 69 and the NFPA Fire Protection Handbook for guidance. Ventilation systems should
be kept clean and precautions should be taken to prevent sparks or other ignition sources.
*Kst the maximum rate of pressure rise is used to calculate the Kst value; an internationally recognized
index used to classify dust explosibility.

Page 2 of 7 Rev. 05/29/2015
6. Accidental Release Measures
Steps to be taken in case Material Is Released or Spilled: Sweep or vacuum up for recovery and
disposal. Avoid creating dusty conditions whenever feasible. Maintain good housekeeping to avoid
accumulation of cellulose dust on exposed surfaces. Use NIOSH approved filtering facepiece
respirator (“dust mask”) where ventilation is not possible and exposure limits may be exceeded or for
additional worker comfort.
Other Precautions: Minimize compressed air blowdown or other practices that generate high dust levels.
7. Handling and Storage
Precautions to be taken in Handling and Storage: Minimize dust generation and accumulation. Keep
in cool, dry place away from open flame and other sources of ignition. Maintain good housekeeping
to avoid accumulation of dried cellulose dust on exposed surfaces. Cellulose dust may pose a
combustible dust hazard.

Ventilation:
LOCAL EXHAUST – Provide local exhaust as needed so that exposure limits are met. Ventilation to
control dust should be considered where potential explosive concentrations and ignition sources are
present. The design and operation of any exhaust system should consider the possibility of explosive
concentrations of cellulose dust within the system. See “SPECIAL” section below.
Weyerhaeuser SDS WC S453-01 (M)
Page 3 of 7 Rev. 12/28/2014
8. Exposure Control Measures/Personal Protection (cont’d.)
MECHANICAL (GENERAL) – Provide general ventilation in processing and storage areas so that
exposure limits are met.
SPECIAL – Ensure that exhaust ventilation and material transport systems involved in handling these
products contain explosion relief vents or suppression systems designed and operated in accordance
with applicable standards if the operating conditions justify their use.
OTHER ENGINEERING CONTROLS – NAP
Personal Protective Equipment:
RESPIRATORY PROTECTION – Use filtering face piece respirator (“dust mask”) tested and approved
under appropriate government standards such as NIOSH (US), CSA (Canada), CEN (EU), or JIS
(Japan) where ventilation is not possible and exposure limits may be exceeded or for additional
worker comfort or symptom relief when fiberization of the pulp occurs. Use respiratory protection in
accordance with jurisdictional regulatory requirements similar to the OSHA respiratory protection
standard 29CFR 1910.134 following a determination of risk from potential exposures.
EYE PROTECTION – Not applicable for products in purchased form. However, goggles or safety glasses
are recommended if the products are used in such a way as to generate high dust levels.
PROTECTIVE GLOVES – Not normally required. However, cloth, canvas, or leather gloves are
recommended to minimize potential mechanical irritation from handling these products.
OTHER PROTECTIVE CLOTHING OR EQUIPMENT – Not applicable for product in purchased form.
Outer garments may be desirable in extremely dusty areas.
WORK/HYGIENE PRACTICES – Follow good hygienic and housekeeping practices. Clean up areas
where cellulose dust settles to avoid excessive accumulation of this combustible material. Minimize
compressed air blowdown or other practices that generate high airborne-dust concentrations.
