HEALTH HAZARD INFORMATION
Health Effects
Acute - Swallowed May be harmful if swallowed. Causes irritation and burns to the mouth and
stomach.
Acute - Eye Causes burns. Material is extremely destructive to the eyes.

Chronic Prolonged exposure to iodides may produce iodism in sensitive individuals.
Symptoms of exposure include: skin rash, running nose, headache and irritation of
the mucous membrane. For severe cases the skin may show pimples, boils, hives,
blisters and black and blue spots.
First Aid
Swallowed Rinse mouth thoroughly with water immediately. Give plenty of water to drink.

Other Health Hazard Information
Teratogenicity Exposure to excessive amounts of iodine during pregnancy is capable of producing
fetal hypothyroidism. Iodides are readily diffused across the placenta.
Iodine-containing drugs have been associated with fetal goiter. Neonatal deaths
from respiratory distress secondary to goiter have been reported.
PRECAUTIONS FOR USE
Other Exposure A time weighted average (TWA) concentration for an 8 hour day, and 5 day week
Info. has not been established by NOHSC Australia for this product. There is a blanket
limit of 10 mg/m鲁 for dusts or mists when limits have not otherwise been
