Hazards and Protection.
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.
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.
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.
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
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.
It is stable to 100 C in aqueous suspensions from slightly acid (ph 6) to alkaline.
Strong oxidizing agents.
When heated to decomposition, emits acrid smoke and irritating fumes.
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. Use agent most appropriate to extinguish fire.
Toxic gases and vapors may be released in a fire involving organic tin compounds.
NIOSH REL: TWA 5 mg/m3 OSHA PEL: TWA 0.32 mg/m3 [0.1 mg/m3 (as Sn)] IDLH 80 mg/m3 [25 mg/m3 (as Sn)]
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
Abdominal pain, nausea, vomiting, diarrhea, loss of appetite and sore throat have been reported.
Some tin compounds may cause sensitization, irritation or burns, and may be percutaneously absorbed.
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.
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.
If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention.
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
