Section 3 - Hazards Identification

EMERGENCY OVERVIEW

Appearance: white crystalline powder. Hygroscopic (absorbs moisture from the air).
Target Organs: Kidneys, liver, respiratory system, eyes, skin.


Potential Health Effects
Eye: Causes severe eye irritation. May cause eye burns. Causes redness and pain.
Skin: Harmful if absorbed through the skin. Contact with skin causes irritation and possible burns, especially if the skin is wet or moist. Causes redness and pain.
Ingestion: Harmful if swallowed. May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns. May cause hemorrhaging of the digestive tract.
Inhalation: May cause severe irritation of the upper respiratory tract with pain, burns, and inflammation.
Chronic: May cause liver and kidney damage.

Section 4 - First Aid Measures


Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Skin: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion: If victim is conscious and alert, give 2-4 cupfuls of milk or water. Do NOT induce vomiting and seek IMMEDIATE MEDICAL ADVICE.
Inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician: Treat symptomatically.

Section 5 - Fire Fighting Measures
