First Aid Measures

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.

Inhalation

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.

Skin

Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.

Eyes

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.

Handling and Storage

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.

Hazards Identification

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.

Ingestion

Abdominal pain, nausea, vomiting, diarrhea, loss of appetite and sore throat have been reported.

Exposure Controls/Personal Protection

Personal 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.

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

Exposure limit(s)

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)]

Poison Class

Fire Fighting Measures

Flash Point

212

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. Use agent most appropriate to extinguish fire.

Accidental Release Measures

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 and Reactivity

Stability

It is stable to 100 C in aqueous suspensions from slightly acid (ph 6) to alkaline.

Incompatibilities

Strong oxidizing agents.

Decomposition

When heated to decomposition, emits acrid smoke and irritating fumes.

Combustion Products

Toxic gases and vapors may be released in a fire involving organic tin compounds.
