4 - First Aid Measures
AFTER INHALATION
If inhaled, remove to fresh air. If breathing becomes difficult,
call a physician.
AFTER SKIN CONTACT
In case of contact, immediately wash skin with soap and copious
amounts of water.

In case of contact with eyes, flush with copious amounts of
water for at least 15 minutes. Assure adequate flushing by
separating the eyelids with fingers. Call a physician.
AFTER INGESTION
If swallowed, wash out mouth with water provided person is
conscious. Call a physician.

SIGNS AND SYMPTOMS OF EXPOSURE
Inorganic tin salts are poorly absorbed into the body. When
parenterally administered tin salts are highly toxic. Tin oxide
inhaled as a dust or fume leads to a benign pneumoconiosis with
no sign of interference with pulmonary function. Deposited dust
appears nodular with the particles being mostly extracelluar. No
SIAL - 204714 www.sigma-aldrich.com Page 3
necrosis, foreign-body giant-cell reaction, or collagen
formation has been seen. Tin salts that have gained access to
the blood stream are highly toxic and produce neurologic damage
and paralysis. With most common tin salts, the toxicity profile
is complicated by hydrolysis in body fluids producing
unphysiologic pH values. The reported symptoms of hyperemia,
vascular changes with bleeding in the central nervous system,
liver, heart, and other organs may be due to tin itself or to
the unphysiological pH changes. Ingestion produces vomiting due
to the gastric irritation from the activity and astringency of
tin compounds. Injection of inorganic tin salts produces
diarrhea, muscle paralysis, and twitching.
ROUTE OF EXPOSURE
Skin Contact: May cause skin irritation.
Skin Absorption: May be harmful if absorbed through the skin.
Eye Contact: May cause eye irritation.
