Potential Health Effects
----------------------------------
Inhalation:
Causes irritation to the respiratory tract. Symptoms may include coughing,
shortness of breath. High concentrations can cause pulmonary edema.
Ingestion:
Causes burns of gastrointestinal tract. May cause vomiting and all degrees
of cerebral depression or excitation, including delirium, hallucinations,
coma, and death. A rapid pulse with or without a fever is characteristic.
High concentrations applied to the skin have caused damage to the heart,
liver, and kidneys.
Skin Contact:
May cause irritation or dermatitis. Can be absorbed through skin and
produce systemic effects; symptoms may parallel ingestion.
Eye Contact:
May cause severe irritation, redness, pain. Visual disturbances or
impairment may occur.
Chronic Exposure:
May cause "iodism" on prolonged absorption. Symptoms are skin rash,
headache and skin eruptions in severe cases.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or impaired respiratory function
may be more susceptible to the effects of the substance.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Get medical attention.
Ingestion:
Induce vomiting immediately as directed by medical personnel. Never give
anything by mouth to an unconscious person. Get medical attention
immediately.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Call a physician, immediately.
Wash clothing before reuse.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes,
lifting lower and upper eyelids occasionally. Get medical attention
immediately.
5. Fire Fighting Measures
Fire:
Not considered to be a fire hazard. Toxic gases and vapors may be released
if involved in a fire.
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. Protect from physical damage. Store in
a cool, dry, ventilated area away from sources of heat, moisture and
incompatibilities. 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:
-ACGIH Threshold Limit Value (TLV): 0.6 ppm (TWA)
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee
exposures below the Airborne
Exposure Limits. 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):
If the exposure limit is exceeded, wear a supplied air, full-facepiece
respirator, airlined hood, or full-facepiece self-contained breathing
apparatus.
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. Maintain eye wash fountain and quick-drench
facilities in work area.

12. Ecological Information
Environmental Fate:
When released into the soil, this material may leach into groundwater. When
released into water, this material may evaporate to a moderate extent. When
released into the water, this material is expected to have a half-life
between 1 and 10 days. This material has an estimated bioconcentration
factor (BCF) of less than 100. This material is not expected to
significantly bioaccumulate. When released into the air, this material may
be moderately degraded by reaction with photochemically produced hydroxyl
radicals. When released into the air, this material is expected to have a
half-life of greater than 30 days.
Environmental Toxicity:
This material is expected to be toxic to terrestrial life. This material is
expected to be toxic to aquatic life. The LC50/96-hour values for fish are
between 1 and 10 mg/l.
13. Disposal Considerations
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.
