HEALTH HAZARDS (Acute and Chronic): ACUTE- Eye: May cause irreversible eye injury. Vapor or mist may cause irritation and severe burns. Contact with liquid is

corrosive to the eyes and causes severe burns. Skin: May be absorbed through the skin in harmful amounts. Contact with liquid is corrosive and causes severe burns

and ulceration. Ingestion: May cause circulatory system failure. Causes severe digestive tract burns with abdominal pain, vomiting, and possible death. May cause

corrosion and permanent tissue destruction of the esophagus and digestive tract. Inhalation: Causes severe irritation of upper respiratory tract with coughing, burns,

breathing difficulty, and possible coma. May cause pulmonary edema and severe respiratory disturbances. CHRONIC: Prolonged or repeated skin contact may cause

dermatitis. Repeated exposure may cause erosion of teeth. May cause conjunctivitis and photosensitization.



COMPONENTS LISTED AS CARCINOGENS OR POTENTIAL CARCINOGENS: None reported



SIGNS AND SYMPTOMS OF EXPOSURE: Irritation or burns of eyes, skin, digestive tract, and upper respiratory tract.



MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: Dermatitis, Respiratory disorders



EMERGENCY AND FIRST AID PROCEDURES: Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids. Get medical

aid immediately. Do NOT allow victim to rub or keep eyes closed. Skin: Get medical aid. Rinse area with large amounts of water for at least 15 minutes. Remove

contaminated clothing and shoes. Ingestion: Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately.

Inhalation: Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. Notes to

Physician: Treat symptomatically and supportively. No specific antidote exists.







Section VII - Precautions for Safe Handling and Use



STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Contain if possible, neutralize with lime, sodium bicarbonate, limesone. Absorb with inert

material.
