Principle Routes of Exposure

Inhalation, ingestion, direct contact

Potential health effects

(ACUTE AND CHRONIC): INHALATION: Causes irritation of nose, throat, and lungs. Inhalation of concentrated vapor or mist will damage upper respiratory tract and lung tissues. Death may result from gross overexposure. INGESTION: Swallowing may be fatal. DIRECT CONTACT: Contact with liquid, mist, or vapor can cause immediate irritation or corrosive burns to all human tissue. EYE CONTACT: Contact with eyes may result in permanent visual loss unless removed quickly by thorough irrigation with water. CARCINOGENS (NTP, IARC,

Medical Conditions Generally Aggravated by Exposure

BY EXPOSURE: Repeated exposure may cause chronic bronchitis or respiratory inflammation. Repeated skin contact with dilute solutions may cause dermatitis. SECTION 7 ~- FIRST AID INHALATION: Remove victim to fresh air. If not breathing, perform artificial respiration. Get medical attention. INGESTION: Drink copious amounts of water or milk. Do not induce vomiting. Get immediate medical attention. DIRECT CONTACT: Flush immediately with water for at least 15 minutes while removing contaminated clothing. Get immediate medical attention. Wash clothing before re-use. Destroy contaminated shoes. DIRECT EYE CONTACT: Flush immediately with water for at least 15 minutes. Forcibly hold eyelids apart to ensure complete irrigation of eye/lid tissue. Get immediate medical attention. SECTION 8

Precautionary statements

FOR SAFE STORAGE, HANDLING AND USE TO BE TAKEN IN HANDLING AND STORAGE: Store away from heat and oxidizing agents. Keep containers closed and dry. Protect container from physical damage. Do not strike containers or fittings with tools or hard objects. Wash thoroughly after handling. Emptied container may retain vapor and product residue. STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Contain spill in order to prevent contamination of sewage system or water way. Pump into marked containers for reclamation or disposal. If possible, neutralize on a dry basis' with suitable alkali such as lime or soda ash; then flush with water in accordance with applicable regulations. WASTE DISPOSAL METHODS: Dispose of spilled, neutralized, or waste product, contaminated soil and other contaminated materials in licensed landfill or treatment facility in accordance with all local, state and federal regulations.
