Section III – Hazards Identification
ROUTES OF ENTRY
/ Inhalation? Yes / Skin? Yes / Ingestion? Yes
HEALTH HAZARDS (Acute and Chronic): ACUTE – Eye: causes severe eye irritation or burns. Skin: Causes skin irritation or burns. Ingestion: May cause gastrointestinal tract irritation or burns with pain, nausea, vomiting, diarrhea, and shock. Inhalation: Irritation may lead to chemical pneumonitis and pulmonary edema. May cause irritation of upper respiratory tract with coughing, burns, breathing difficulty, and possible coma. CHRONIC – Prolonged or repeated skin contact may cause dermatitis.
COMPONENTS LISTED AS CARCINOGENS OR POTENTIAL CARCINOGENS: Strong inorganic acids mists containing sulfuric acid are considered to be carcinogenic by ACGIH, NTP, IARC, and the State of California.
SIGNS AND SYMPTOMS OF EXPOSURE: Irritation and/or burns of eyes, skin, digestive tract, and upper respiratory tract.
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: Skin conditions, respiratory conditions.
Section IV – First Aid Measures
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. 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. Ingestion: Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. 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.
