SECTION 3: Hazards Identification
Emergency Overview: Organo tin compounds may act as delayed poisons, causing headache, dizziness; psycho-neurologic disturbances; sore throat, vomiting; urine retention; vision impairment; skin burns, liver and kidney damage.
Primary Routes of Exposure: Ingestion, inhalation, skin, eyes
Eye Contact: Causes severe burns to the eyes and blindness.
Skin Contact: Prolonged contact will cause redness and corrosive acid burns to the skin.
Inhalation: Corrosive to the nose, mucous membranes and respiratory tract. High doses may cause long term neurological damage.
Ingestion: Delayed and permanent psycho-neurologic disturbances; impairment of vision, unsteadiness, nausea and vomiting.
Acute Health Effects: Corrosive to skin, eyes and mucous membranes. Ingestion of certain organotin compounds may cause delayed poisoning (4 days) with cerebral edema causing damage to the central nervous system.
Chronic Health Effects: Repeated exposure to certain organic tin compounds may cause problems with vision, skin, respiratory system, central nervous system, liver, kidneys, urinary tract, and blood.
SECTION 4: First Aid Measures
Eye Exposure: Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure: Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists.
Inhalation: Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.
Ingestion: Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel.
