Potential Health Effects
----------------------------------
Inhalation:
May cause irritation to the respiratory tract. Symptoms may include
coughing and shortness of breath.
Ingestion:
Large oral doses may cause irritation to the gastrointestinal tract.
Skin Contact:
No adverse effects expected but may cause minor skin irritation.
Eye Contact:
May cause irritation, redness and pain.
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:
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. Small amounts of residue may be flushed to sewer with
plenty of water.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area.
Protect against physical damage. Isolate from incompatible substances.
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 the dust or mist is apparent, a
half-face dust/mist respirator may be worn. 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.
