11 - Toxicological Information
RTECS NUMBER: MD5428000
SENSITIZATION
Skin: May cause allergic skin reaction.
SIGNS AND SYMPTOMS OF EXPOSURE
Material is extremely destructive to tissue of the mucous
membranes and upper respiratory tract, eyes, and skin.
Inhalation may result in spasm, inflammation and edema of the
larynxand bronchi, chemical pneumonitis, and pulmonary edema.
Symptoms of exposure may include burning sensation, coughing,
wheezing, laryngitis, shortness of breath, headache, nausea, and
vomiting. Exposure can cause stomatitis, metallic taste,
itching, erythema, eczema, erythema multiforme, exfoliative
dermatitis, thrombocytopenia, leucopenia, agranulocytosis, and
aplastic anemia. Exposure can also cause a gray-to-blue
pigmentation (chrysiasis) in the skin and mucous membranes,
especially in areas exposed to light. Gold deposits may occur in
the eyes causing keratitis and corneal ulceration.
ROUTE OF EXPOSURE
Skin Contact: Causes burns.
Skin Absorption: May be harmful if absorbed through the skin.
Eye Contact: Causes burns.
Inhalation: Material is extremely destructive to the tissue of

the mucous membranes and upper respiratory tract. May be harmful
if inhaled.
Ingestion: May be harmful if swallowed.
