**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Not available.

Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation. Prolonged and/or repeated contact may
cause irritation and/or dermatitis. Low hazard for usual industrial
handling.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. Low hazard for usual industrial handling. Ingested
inorganic tin exhibits only moderate toxicity due to poor absorption
and rapid tissue turnover. Ingestion of large amounts may cause
gastrointestinal irritation, nausea, cramps, vomiting and diarrhea.
May interfere with various enzyme systems. Inorganic tin salts may
cause systemic effects on the central nervous system, heart and
liver.
Inhalation:
Dust is irritating to the respiratory tract. Inhalation of fumes may
cause metal fume fever, which is characterized by flu-like symptoms
with metallic taste, fever, chills, cough, weakness, chest pain,
muscle pain and increased white blood cell count. When inhaled as a
dust or fume, may cause benign pneumoconiosis.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Chronic
exposure to tin oxide dusts and fumes may result in stannosis (benign
pneumoconiosis).

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. If irritation
develops, get medical aid.
Skin:
Get medical aid if irritation develops or persists. Wash clothing
before reuse. Flush skin with plenty of soap and water.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Get medical aid if irritation or symptoms
occur.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid if cough or other symptoms appear.
Notes to Physician:

**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Dusts at sufficient concentrations can form
explosive mixtures with air. During a fire, irritating and highly
toxic gases may be generated by thermal decomposition or combustion.
Extinguishing Media:
Do NOT use carbon dioxide. If water is the only media available, use
in flooding amounts. Use dry sand, dry chemical, soda ash or lime.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Sweep up or absorb material, then place into a
suitable clean, dry, closed container for disposal. Avoid generating
dusty conditions. Provide ventilation.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Avoid contact with eyes, skin, and
clothing. Avoid ingestion and inhalation.
Storage:
Keep from contact with oxidizing materials. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep
containers tightly closed.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
Exposure Limits

Personal Protective Equipment

Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant respirator use.
