1. Identification

Product name: 1st grade reclaimed fluff pulp

Manufacturer information:
Recyc PHP Inc.
2575-28A St-Joseph bld., Drummondville (QC) J2B 7V4, Canada

2. Hazards identification

Fluff pulp:

Warning! Fluff pulp may form combustible dust concentrations in air during processing. Specifically, in instances where product dust is suspended in air in sufficient concentrations in proximity to an ignition source. Users of this product should examine the potential to generate cellulose dust during handling and processing and related combustibility hazards and controls. See additional comments in MSDS. The primary health hazard posed by this product is thought to be due to exposure to cellulose dusts.

Sodium polyacrylate:

The sodium polyacrylate contained in the fluff pulp is a white  polyacrylate, granular and odourless who takes a freezing consistence if you add water. It’s insoluble in water and makes the surface very slippery once wet. This product is not designed like dangerous in the regulation, but the inhalable dust is a potential irritating for the respiratory breath. The manufacturer recommends a limit exposition on eight hours on 0,05 mg/m3.

Information on composant  / non dangerous composants

Those products are not designed on dangerous product in the regulation 29 CFR and 49 CFR. Otherwise, the manufacturer knows that the healthy irritation potential when you take a breath must have some disagreement. You can have more information if you look at the list’s number 8, 11, 14 and 15.

Appearance and Odor: The product is an odorless white baled pulp.

Primary Route(s) of Exposure:

  •  Ingestion: Although ingesting is not a reality, few testing proved that the polyacrylate absorbent is not toxic in this case. However, in any importance case of the alimentary product, you can obtain medical assistance if negative symptoms develop.
  •  Skin: The exposure to the dust in the fabrication activities can worsen an already existing skin illness because of the drying effect.
  •  Inhalation: Dust exposure can irritate the respiratory system and can aggravate an existent respiratory   illness.
  •  Eye: Dust can cause a burning feeling, watering, itching, and other symptoms. This will result in eye redness.

Medical Conditions Generally Aggravated by Exposure: Cellulose and SAP dust may aggravate pre-existing respiratory conditions or allergies.

Signs and Symptoms of Exposure: Acute Health Hazards: Dust might be a mechanical irritant to the eyes.

Chronic Health Hazards: Cellulose (pulp) dust has not been shown to produce significant disease or toxic effects when exposure limits are met. Cellulose is poorly soluble and has a low order of toxicity.

Carcinogenicity Listing: NTP: Not listed, IARC Monographs: Not listed, OSHA Regulated: Not listed.

4. First-Aid Measures

  • Ingestion: Non-toxic by ingestion. However, if you have some persisting symptom, please contact your medical assistance.
  • Eye Contact: Dust may mechanically irritate the eyes, resulting in redness or watering. Treat dust in the eye as a foreign object. Immediately rinse your eyes with water during approximately 15 minutes to remove dust particles. Seek medical help if irritation persists.
  • Skin Contact: Take off dust absorbent polyacrylate on your skid with soap and water.
  • Skin Absorption: Product is not known to be absorbed through the skin.
  • Inhalation: Excessive dust concentrations may cause unpleasant deposits or obstruction in the nasal passages. Remove to fresh air. Seek medical help if persistent irritation, severe coughing or breathing difficulty occurs.

5. Fire-Fighting Measures

  • Flash point (method used): NAP
  • Flammable limits:   LEL = NOTE: See below under       UEL = NAP

*Unusual Fire and Explosion Hazards”

  • Extinguishing media: Water mist, foam, carbon dioxide, dry powder.
  • Auto ignition temperature: 450°F (232°C)
  • Special firefighting procedures: No special requirements.

Unusual fire and explosion hazards: Pulp processing (e.g. fiberization) may result in the release of cellulose fibers. Bulk pulp as supplied and shipped in rolled or baled/sheet form is 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 are produced. Reference NFPA standards 654, 69 and the NFPA Fire Protection Handbook for guidance.

*Kst the maximum rate of pressure rise is used to calculate the Kst value; an internationally recognized index used to classify dust explosibility.

HMIS Rating (Scale 0-4): Health = 1    Fire = 1  Physical Hazard = 0

NFPA Rating (Scale 0-4): Health = 1    Fire = 1  Reactivity = 0

Risk scale : 0 = Minimal 1 = Light 2 = Medium 3 = Serious 4 = Extreme * = Intoxication risk chronicle

6. Accidental Release Measures

Steps to be Taken in Case Material Is Released or Spilled: Sweep or vacuum up for recovery and disposal. Spilled products in contact with water or moisture causes surfaces to become extremely slippery. Avoid creating dusty conditions whenever feasible. Maintain good housekeeping to avoid accumulation of cellulose dust on exposed surfaces. Use NIOSH approved filtering face piece respirator (“dust mask”) and goggles where ventilation is not possible and exposure limits may be exceeded or for additional worker comfort.

Environmental precautions: Collect and flush small residual with much water into the drain for subsequent biological waste effluent treatment.

Other Precautions: Minimize compressed air blow down or other practices that generate high dust levels.

7. 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.

8. Exposure Controls/Personal Protection

Components with workplace control parameters

Remarks: The European Disposables and Non-Wovens Ass. (EDANA) recommends a workplace limit of 0,05 mg/cbm for inhalable dust of super absorbent polymer (particle size under 10 microns), based on the Noël (No Observed Effect Level) of the two-year inhalation study (see section 11).

Base:  MAK

Value:  0,05 mg/m3 / A Kat.4

Personal Protective Equipment:

RESPIRATORY PROTECTION – Use NIOSH-approved filtering face piece respirator (“dust mask”) and goggles where ventilation is not possible and exposure limits may be exceeded or for additional worker comfort or symptom relief when deballing of the pulp occurs. Use respiratory protection in accordance with regulatory requirements such as the OSHA respiratory protection standard 29CFR 1910.134.

PROTECTIVE GLOVES – Not normally required. However, cloth, canvas, or leather gloves are recommended to minimize potential mechanical irritation from handling products.

EYE PROTECTION – 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 – 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 blow down or other practices that generate high airborne-dust concentrations.


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.

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 this product contain explosion relief vents or suppression systems designed and operated in accordance with applicable standards if the operating conditions justify their use.

OTHER – None
