Potential Health Effects
----------------------------------
Information on the human health effects from exposure to this substance is
limited.
Inhalation:
Corrosive. Extremely destructive to tissues of the mucous membranes and
upper respiratory tract. Symptoms may include burning sensation, coughing,
wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.
Inhalation may be fatal as a result of spasm inflammation and edema of the
larynx and bronchi, chemical pneumonitis and pulmonary edema.
Ingestion:
Extremely destructive to tissues. May be fatal.
Skin Contact:
Extremely destructive to skin. Causes irritation, redness, pain, and burns.
Eye Contact:
Extremely destructive to eyes. Causes irritation, redness, pain, and burns.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
No information found.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Call a physician immediately.
Ingestion:
DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything
by mouth to an unconscious person. Call a physician immediately.
Skin Contact:
In case of contact, wipe off excess material from skin then immediately
flush skin with plenty of water for at least 15 minutes. Remove
contaminated clothing and shoes. Wash clothing before reuse. Call a
physician immediately.
Eye Contact:
Immediately flush eyes with gentle but large stream of water for at least
15 minutes, lifting lower and upper eyelids occasionally. Call a physician
immediately.
5. Fire Fighting Measures
Fire:
Flash point: 184C (363F) CC
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. May react
strongly with water.
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
Remove all sources of ignition. Ventilate area of leak or spill. Wear
appropriate personal protective equipment as specified in Section 8. Keep
unnecessary and unprotected personnel from entering hazard area.
Spills: Clean up spills in a manner that does not disperse dust into the
air. Use non-sparking tools and equipment. Reduce airborne dust and prevent
scattering by moistening with water. Pick up spill for recovery or disposal
and place in a closed container.
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.
Protect from moisture. 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 impervious protective clothing, including boots, gloves, lab coat,
apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or full face shield where dusting or
splashing of solutions is possible. Maintain eye wash fountain and
quick-drench facilities in work area.

12. Ecological Information
Environmental Fate:
When released into the soil, this material is expected to leach into
groundwater. When released into water, this material may biodegrade to a
moderate extent. When released into water, this material is not expected to
evaporate significantly. When released into the air, this material is
expected to be readily removed from the atmosphere by wet deposition. This
material is not expected to significantly bioaccumulate.
Environmental Toxicity:
No information found.
13. Disposal Considerations
Whatever cannot be saved for recovery or recycling should be managed in an
appropriate and approved waste facility. Although not a listed RCRA
hazardous waste, this material may exhibit one or more characteristics of a
hazardous waste and require appropriate analysis to determine specific
disposal requirements. 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.
