Threshold Limit Value: ND

Effects of Overexposure:
Overexposure by contact may cause mild to severe irritation of burns of skin, eyes and mucos membranes. Splashes in the eye may cause damage with ulceration of the cornea, prolonged contact may cause irreversible eye damage including blindness.

Ingestion (Swallowing):
Miniscule amount swallowed during proper use should not cause injury. Ingestion of large amount may cause irritation of the upper GI tract with pain and distention of the stomach and esophagus due to the liberation of oxygen.

Emergency and First Aid Procedures:
Eyes - Immediately flush with plenty of water for at least 15 minutes. Seek medical attention.
Skin - Immediately flush with plenty of water for at least 15 minutes.
Inhalation - Small amount of product will not emit concentrated amount of vapors. In case of breathing difficulty or shortness of breath secondary to ingestion of large amount of product, immediately move to a well ventilated area. If not breathing, give artificial respiration.
Ingestion - If swallowed in large amounts, do not induce vomiting. Give large amounts of water. Seek medical attention if abdominal discomfort persists.


SECTION V - REACTIVITY DATA
