Potential Health Effects
----------------------------------
There is insufficient data in the published literature to perform a complete
hazard evaluation for this product. Special precautions must be used in storage,
use and handling. Protective equipment should be chosen using professional
judgment.
Inhalation:May cause irritation to respiratory tract resulting in
coughing and sneezing.
Ingestion: Low systemic toxicity. Large amounts may cause some
gastrointestinal discomfort, nausea or diarrhea.
Skin Contact: May cause irritation to the skin with redness or minor
inflammation on moist skin.
Eye Contact: May cause eye irritation due to possible temporary
abrasiveness. Can cause redness, tearing and possibly some pain.
Chronic Exposure: No information found.
Aggravation of Pre-existing Conditions: No adverse health effects
expected.
Inhalation:
Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion: Give several glasses of water to drink to dilute. If large
amounts were swallowed, get medical advice.
Skin Contact: Wash exposed area with soap and water. Get medical advice
if irritation develops.
Eye Contact: Wash eyes with plenty of water for at least 15 minutes. Call
a physician.
Fire:
As
with most organic solids, fire is possible at elevated temperatures or by
contact with an ignition source.
Explosion: Not considered to be an explosion hazard.
Fire Extinguishing Media: Water spray, dry chemical, alcohol foam, or
carbon dioxide.
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.
Remove
all sources of ignition. 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.
Keep
in a tightly closed container, stored in a cool, dry, ventilated area. Protect
against physical damage. Protect from light. 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.
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.
Appearance:
Fine crystals, white yellowish-white or pale, fawn-colored.

concentrations.
Whatever
cannot be saved for recovery or recycling should be managed in an appropriate
and approved waste disposal facility. Processing, use or contamination of this
product may change the waste management options. State and local disposal
regulations may differ from federal disposal regulations. Dispose of container
and unused contents in accordance with federal, state and local requirements.
