| Hazards and Protection. | |
| Storage | Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage. |
| Handling | All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood. |
| Protection | Safety goggles or face shields should be worn (8 inch minimum). Impervious clothing should include gloves, aprons, and suits. Wear appropriate chemical protective gloves, boots, goggles and clothing. |
| Respirators | Use NIOSH/MSHA approved respirator appropriate for exposure of concern. |
| Small spills/leaks | Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces. |
| Stability | It is stable to 100 C in aqueous suspensions from slightly acid (ph 6) to alkaline. |

| Poison_Class | 3 |
| Exposure effects | Triphenyl tin: encephalopathy, polyneuropathy trimethyl tin: tinnitus, lightheadedness, aggression, unresponsiveness; seizures in one human case and in experimental animals tributyl tin: weakness, loss of appetite, headache trialkyl tin: eeg abnormalities and altered consciousness diiododiethyl tin: headache and cerebral edema |
| Ingestion | Abdominal pain, nausea, vomiting, diarrhea, loss of appetite and sore throat have been reported. |
| Skin | Some tin compounds may cause sensitization, irritation or burns, and may be percutaneously absorbed. |
| Eyes | Stannic chloride, when mixed with water, fumes, releasing an agent which is corrosive and irritating to eyes, nose and skin. Trialkyl tins may produce ocular irritation. |
First aid |
|
| Ingestion | Seek medical attention. If individual is drowsy or unconscious, do not give anything by mouth; place individual on the left side with the head down. Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended. |
