Section 3 - Hazards Identification


Appearance: white. Danger! If swallowed, do not induce vomiting. getmedical attention immediately. if victim is fully conscious, give acupful of water. never give anything by mouth to an unconsciousperson. Corrosive. May cause kidney damage. May cause severerespiratory and digestive tract irritation with possible burns. Maycause severe eye and skin irritation with possible burns. If inhaled,remove to fresh air and get medical aid immediately.
Target Organs: Kidneys.

Potential Health Effects

Eye: Contact with eyes may cause severe irritation, and possible eye burns.
Skin: Prolonged and/or repeated contact may cause irritation and/or dermatitis. Contact with skin causes irritation and possible burns, especially if the skin is wet or moist.
Ingestion: Causes gastrointestinal tract burns. May cause kidney damage. Causes severe pain, nausea, vomiting, diarrhea, and shock. May cause hemorrhaging of the digestive tract. Overexposure can cause hypocalcemia and kidney injury.
Inhalation: May cause severe irritation of the upper respiratory tract with pain, burns, and inflammation.
Chronic: Not available.

Section 4 - First Aid Measures

Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids. Get medical aid immediately.
Skin: Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Discard contaminated clothing in a manner which limits further exposure.
