Ingestion: May cause gastrointestinal tract irritation 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.
