Potential Health Effects
----------------------------------
Inhalation:
Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of
breath.
Ingestion:
Causes irritation to the gastrointestinal tract. Symptoms may include nausea, vomiting
and diarrhea. May cause burning in mouth and throat, abdominal pain, reduced blood
pressure, stomach bleeding, collapse and convulsions. May cause liver and kidney
damage.
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching, and pain.
Eye Contact:
Causes irritation, redness, and pain.
Chronic Exposure:
Repeated skin contact with solutions may cause skin rashes in susceptible individuals.
Prolonged inhalation of dust or fume may result in a benign pneumoconiosis, producing
distinctive changes in the lungs with no apparent disability or complications.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems, or impaired liver, kidney or
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.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated
clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean
shoes before reuse.

STANNOUS CHLORIDE Page 3 of 8
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.
Explosion:
Not considered an explosion hazard, but reacts explosively when mixed with nitrates or
hydrogen peroxide (> 3% solution). Sealed containers may rupture when heated.
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. Aqueous solutions of this material are acidic. Avoid its contact with eyes
and skin. Avoid breathing its fumes or dust. When heated to decomposition it emits toxic
and corrosive fume of hydrochloric acid.
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. Aqueous solutions are acidic; use
only in corrosion-resistant vessels. 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:
Inorganic Tin Compounds, as Sn:
-OSHA Permissible Exposure Limit (PEL):2 mg/m3 (TWA)
-ACGIH Threshold Limit Value (TLV): 2 mg/m3 (TWA)
-NIOSH Recommended Exposure Limits (REL): 2 mg/m3 (TWA).
Ventilation System:
http://www.jtbaker.com/msds/s6434.htm 1/1/99
STANNOUS CHLORIDE Page 4 of 8
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, a full facepiece respirator with dust/mist filter may be
worn up to 50 times the exposure limit or the maximum use concentration specified by
the appropriate regulatory agency or respirator supplier, whichever is lowest. For
emergencies or instances where the exposure levels are not known, use a full-facepiece
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.

10. Stability and Reactivity
Stability:
Powerful reducing agent. Small quantities of hydrochloric acid are present in aqueous
solutions. Absorbs oxygen from air and forms the insoluble oxychloride. Forms an
insoluble basic salt when dissolved with much water.
Hazardous Decomposition Products:
When heated to decomposition it emits toxic and corrosive fume of hydrochloric acid.
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Sodium, potassium, bromine trifluoride, calcium carbide, calcium acetylide, ethylene
oxide, and nitrates. Reacts with hydrazine hydrate to form dihydrazine chloride, which
decomposes explosively when heated. Contact with strong oxidizing agents or alkalis will
generate heat and fumes.
Conditions to Avoid:
Moisture, heat, flames, ignition sources and incompatibles.
11. Toxicological Information
