HEALTH & SAFETY INFORMATION
• IDLH:

mg[Sn]/m3
•
Studies in animals have not shown evidence of carcinogenicity for inorganic
tin. A study in rats and another in mice showed that a specific organotin,
triphenyltin hydroxide, can produce cancer in animals after long-term oral
administration. The U. S. Department of Health and Human Services, the
International Agency for Research on Cancer (IARC), and the EPA have not
classified metallic tin or inorganic tin compounds for carcinogenicity. The EPA
has determined that a specific organotin, tributyltin oxide, is not
classifiable as to human carcinogenicity.

OSHA Table Z-1 Air Contaminant
•
Dust or fumes is known to cause a pneumoconiosis (stannosis); changes in chest
x-ray; reduced lung function. Tin may contain contaminants of arsenic or lead.
May contribute to iron deficiency by interfering with the body's ability to
absorb iron from food and vitamins. Metallic tin is not very toxic due to its poor
gastrointestinal absorption, but inhalation of fumes of molten metallic tin
can produce adverse pulmonary effects. Human and animal studies show that
ingestion of large amounts of inorganic tin compounds can cause stomach aches,
anemia, and liver and kidney problems. Breathing or swallowing, or skin contact
with some organotins, such as trimethyltin and triethyltin compounds, can
interfere with the way the brain and nervous system work. In severe cases, it
can cause death.
Animal
studies:
Some organotin
compounds, such as dibutyltins and tributyltins, have been shown to affect the
immune system in animals, but this has not been examined in humans. Studies in
animals also have shown that some organotins, such as dibutyltins,
tributyltins, and triphenyltins, can affect the reproductive system. This,
also, has not been examined in humans. Inorganic or organic tin compounds
placed on the skin or in the eyes can produce skin and eye irritation.

FIRE INFORMATION:
Noncombustible solid, but powdered form may ignite. If material
or contaminated runoff enters waterways, notify downstream users of potentially
contaminated water.
FIRST AID:
Eye:
If this chemical contacts
the eyes, immediately wash them with large amounts of water, occasionally
lifting the lower and upper lids. Get medical attention immediately. Contact lenses
should not be worn when working with this chemical.
Skin:
If this chemical contacts the skin,
immediately wash the contaminated skin with soap and water. If this chemical
penetrates the clothing, immediately remove clothing, wash the skin with soap
and water, and get medical attention promptly.
Inhalation:
If a person breathes large amounts of this
chemical, move exposed person to fresh air at once. If breathing has stopped,
perform mouth-to-mouth resuscitation. Keep the affected person warm and at rest.
Get medical attention as soon as possible.
Ingested:
If
this chemical has been swallowed, get medical attention immediately.
