Hazards and Protection.
Storage
Store in a cool, dry, well-ventilated area away from incompatible substances. Keep containers tightly closed. Store protected from moisture.
Handling
Wash thoroughly after handling. Use only in a well ventilated area. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Do not allow contact with water. Wash clothing before reuse. Keep from contact with moist air and steam.
Protection
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
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Small spills/leaks
Clean up spills immediately, using the appropriate protective equipment. Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions. Provide ventilation. Do not get water inside containers. Stop leak only if you can do so without risk.

Stability
May decompose on exposure to moist air or water.
Incompatibilities
Strong oxidizing agents, moisture, triphenyltin chloride.
Decomposition
Hydrogen chloride, carbon monoxide, carbon dioxide, tin/tin oxides.

Fire.
Flash Point,°C
199
Autoignition, °C
> 250
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Containers may explode in the heat of a fire. May be ignited by heat, sparks, and flame. Extinguishing media: For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam. Do NOT get water inside containers. For large fires, use water spray, fog or alcohol-resistant foam.
Fire potential
Combustible material: may burn but does not ignite readily.
Hazards
When heated to decomposition, it emits toxic fumes of chlorides. Hydrolyzes to hydroxide in water. Stable when stored in dark with dry air.
Combustion products
When heated to decomposition it emits toxic fumes of chlorides.

Exposure effects
Confusion, unconsciousness, sensorimotor polyneuropathy, headache, eeg changes, dizziness, vertigo, disorientation, psychosis, and weakness or flaccid paralysis of the limbs may occur. Triphenyltin chloride may cause headache, dizziness, loss of consciousness, convulsions, cerebral edema, neurological damage, and mental disturbances.
   Ingestion
Harmful if swallowed. May cause gastrointestinal irritation with nausea, vomiting and diarrhea.
   Inhalation
Causes respiratory tract irritation. May cause irritation of the mucous membranes.
   Skin
Causes skin irritation. May be absorbed through the skin.
   Eyes
Causes eye irritation.

First aid
 
   Ingestion
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid.
   Inhalation
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
   Skin
Get medical aid immediately. Wash clothing before reuse. SPEEDY ACTION IS CRITICAL! Flush skin with plenty of soap and water. Remove all contaminated clothing immediately.
   Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
