Hazard Statements: Causes skin and serious eye irritation. May cause allergy or asthma 

symptoms or breathing difficulties if inhaled. May cause damage to lungs 

through prolonged or repeated exposure via inhalation.

Precautionary Statements: Prevention: Wear protective gloves and eye/face protection. Wash hands 

thoroughly after handling. Avoid breathing dust. In case of inadequate 

ventilation, wear respiratory protection.

Response: If on skin, wash with plenty of water. If in eyes, rinse cautiously 

with water for several minutes. Remove contact lenses, if present and easy to 

do. Continue rinsing. If skin or eye irritation occurs or persists, get medical 

advice and/or attention. Take off contaminated clothing and wash it before 

reuse. If inhaled and breathing is difficult, remove person to fresh air and 

keep comfortable for breathing. If experiencing respiratory symptoms or 

feeling unwell, get medical attention and/or advice or call a poison control 

center and/or doctor.

between 0.02-0.05 microns. Symptoms may be delayed 4-12 hours and 

begin with a sudden onset of thirst and a sweet, metallic or foul taste in the 

mouth. Other symptoms may include upper respiratory tract irritation 

accompanied by coughing and a dryness of the mucous membranes, 

lassitude and a generalized feeling of malaise. Fever, chills, muscular pain, 

mild to severe headache, nausea, occasional vomiting, exaggerated mental 

activity, profuse sweating, excessive urination, diarrhea, and prostration may 

also occur. Tolerance to fumes develops rapidly, but is quickly lost. All 

symptoms usually subside within 24-36 hours.

dermatitis.

Eye Contact (Acute): Powder may cause moderate irritation. 

Eye Contact (Chronic): Repeated or prolonged exposure to inorganic tin compounds may cause 

conjunctivitis.

Ingestion (Acute): Relatively non-toxic because of poor absorption. At very high levels, 

abdominal pain, nausea, vomiting, gastric irritation, and diarrhea may occur.

Ingestion (Chronic): Repeated or prolonged ingestion of small quantities may cause abdominal 

pain, nausea, constipation, and loss of weight.
