Potential Health Effects
----------------------------------
Information on the human health effects from exposure to this substance is
limited. Used information for a related compound, potassium ferrocyanide,
as a guide. Potassium ferrocyanide is apparently benign and does not
decompose to cyanide in the body.
Inhalation:
May cause irritation to the respiratory tract. Symptoms may include
coughing and shortness of breath.
Ingestion:
Large doses may cause gastrointestinal upset with nausea, vomiting,
diarrhea, and possible cramping.
Skin Contact:
May cause irritation with redness and pain.
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:
Give large amounts of water to drink. Never give anything by mouth to an
unconscious person. Get medical attention.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes. Remove
contaminated clothing and shoes. Wash clothing before reuse. Thoroughly
clean shoes before reuse. Get medical attention 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. May emit toxic and
flammable fumes of cyanide if involved in a fire.
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. Isolate from incompatible substances.
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.
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:
Safety glasses. Maintain eye wash fountain and quick-drench facilities in
work area.

10. Stability and Reactivity
Stability:
Stable under ordinary conditions of use and storage. The aqueous solution
decomposes slowly on standing.
Hazardous Decomposition Products:
When heated to decomposition or comes in contact with acid or acid fumes it
emits toxic fumes of cyanides. Emits toxic fumes of cyanide and oxides of
nitrogen when heated to decomposition.
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Ammonia, chromium trioxide + heat, cupric nitrate, sodium nitrite + heat,
acids and acid fumes.
Conditions to Avoid:
Light, heat, incompatibles.
