EMERGENCY OVERVIEW
Appearance: clear, colorless liquid.
Danger! Causes eye burns. Causes digestive tract
burns. Corrosive. Causes skin burns. Causes respiratory tract burns.
Target Organs: Eyes, skin, mucous membranes.
Potential Health Effects
Eye:
Causes severe eye burns.
Skin:
Causes skin burns. May cause deep, penetrating ulcers of the skin.
May cause deep, penetrating ulcers of the skin.
Ingestion:
Causes gastrointestinal tract burns. Causes severe pain, nausea,
vomiting, diarrhea, and shock.
Inhalation:
Irritation may lead to chemical pneumonitis and pulmonary edema.
Causes severe irritation of upper respiratory tract with coughing,
burns, breathing difficulty, and possible coma.
Chronic:
Chronic inhalation and ingestion may cause effects similar to those
of acute inhalation and ingestion. Chronic ingestion of iodides
during pregnancy has resulted in fetal death, severe goiter, and
cretinoid appearance of the newborn.

Section 4 - First Aid Measures
|
Eyes:
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.

Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
