Hazards and Protection.
Storage
Store in a cool, dry area in a tightly sealed container.
Protection
Safety glasses, rubber gloves, apron, dust mask.
Respirators
NIOSH approved dust respirator.
Small spills/leaks
Isolate spill area and provide ventilation. Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal. Take care not to raise dust.
Stability
Stable at normal temperatures and pressures.
Incompatibilities
Strong acids and bases.
Decomposition
Oxides of sulfur and hydrogen sulfide.

Fire.
Fire fighting
Use suitable extinguishing media for surrounding materials and type of fire. Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes.
Fire potential
Non-flammable.
Hazards
When heated to decomposition, tin sulfide may emit toxic fumes of SOx. Contact with strong acids may liberate hydrogen sulfide which may form explosive mixtures with air.

Health.
Exposure limit(s)
OSHA PEL: 2 mg/m3 as Sn.
Exposure effects
Tin compounds have variable toxicity. Elemental tin and organic compounds have low toxicity and are poorly absorbed when ingested. Some inorganic tin salts are irritating or can liberate toxic fumes on decomposition. Inhalation of tin dusts over a period of years may cause pneumoconiosis. Sulfides of the heavy metals are generally insoluble and hence have little toxic action except through the liberation of hydrogen sulfide
   Ingestion
May cause gastrointestinal irritation. May cause nausea and vomiting.
   Inhalation
May cause irritation to the nose and throat. May cause throat dryness and coughing. Prolonged or repeated exposure may cause pneumoconiosis.
   Skin
May cause irritation. May cause redness and itching.
   Eyes
May cause irritation. May cause redness, itching and watering.

First aid
 
   Ingestion
Give 1-2 glasses of milk or water and induce vomiting. Seek medical attention. Never induce vomiting or give anything by mouth to an unconscious person.
   Inhalation
Remove victim to fresh air, keep warm and quiet, give oxygen if breathing is difficult and seek medical attention.
   Skin
Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water, seek medical attention if symptoms persist.
   Eyes
Flush with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention.
