Potential Health Effects
----------------------------------
Inhalation: Inhalation of dust may cause irritation to the respiratory
tract.
Ingestion: Not expected to be a health hazard via ingestion.
Skin Contact: Not expected to cause any adverse health effects from
skin contact.
Eye Contact: May cause irritation.
Chronic Exposure: No information found.
Aggravation of Pre-existing Conditions: No information found.
4. First Aid Measures
Inhalation: Remove to fresh air. Get medical attention for any
breathing difficulty.
Ingestion: Not expected to require first aid measures. If large amounts
were swallowed, give water to drink and get medical advice.
Skin Contact:
Wash
exposed area with soap and water. Get medical advice if irritation develops.
Eye Contact: Immediately flush eyes with plenty of water for at least
15 minutes, lifting upper and lower eyelids occasionally. Get medical
attention if irritation persists.
5. Fire Fighting Measures
Fire: Not considered to be a fire hazard.
Explosion: Not considered to be an explosion hazard.
Fire Extinguishing Media: Use any means suitable for extinguishing
surrounding fire.
Special Information: In the event of a fire, wear full protective
clothing and NIOSH-approved self-contained breathing apparatus with full
facepiece operated in the pressure demand or other positive pressure mode.
6. Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective
equipment as specified in Section 8. Spills: Sweep up and containerize for
reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust
dispersal.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area.
Protect against physical damage. Containers of this material may be hazardous
when empty since they retain product residues (dust, solids); observe all
warnings and precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits: None established.
Ventilation System: A system of local and/or general exhaust is
recommended to keep employee exposures as low as possible. Local exhaust
ventilation is generally preferred because it can control the emissions of the
contaminant at its source, preventing dispersion of it into the general work
area. Please refer to the ACGIH document, Industrial Ventilation, A Manual
of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved): For conditions of use where
exposure to dust or mist is apparent and engineering controls are not
feasible, a particulate respirator (NIOSH type N95 or better filters) may be
worn. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are
present, use a NIOSH type R or P filter. For emergencies or instances where
the exposure levels are not known, use a full-face positive-pressure,
air-supplied respirator. WARNING: Air-purifying respirators do not protect
workers in oxygen-deficient atmospheres.
Skin Protection: Wear protective gloves and clean body-covering
clothing.
Eye Protection: Use chemical safety goggles. Maintain eye wash fountain
and quick-drench facilities in work area.
