FIRST AID MEASURES Inhalation: Move to fresh air in case of accidental inhalation of vapours or decomposition products. If symptoms develop and persist, get medical attention. Skin contact: Wipe off paste with paper towel or cloth. Wash with soap and water. If skin irritation persists, call a physician. Eye contact: Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Get medical attention. Ingestion: Do not induce vomiting. If symptoms develop and persist, get medical attention. Symptoms: See Section 11. 5. FIRE FIGHTING MEASURES Extinguishing media: Foam, dry chemical or carbon dioxide. Special firefighting procedures: Wear self contained breathing apparatus. Prevent inhalation of fumes and gases. Unusual fire or explosion hazards: None Hazardous combustion products: Oxides of carbon. Oxides of silicon. Formaldehyde. Irritating organic vapours. 6. ACCIDENTAL RELEASE MEASURES Use personal protection recommended in Section 8, isolate the hazard area and deny entry to unnecessary and unprotected personnel. Environmental precautions: Do not allow product to enter sewer or waterways. Clean-up methods: Scrape up as much material as possible. Maintain good ventilation for large spills. Place scrap material in a well ventilated area and allow to cure to rubber. 7. HANDLING AND STORAGE Handling: Prevent contact with eyes, skin and clothing. Do not breathe vapor and mist. Wash thoroughly after handling. Do not handle contact lenses until all sealant has been removed from hands. Residual sealant may transfer to lenses and cause eye irritation. Storage: For safe storage, store between 8 ?C (46.4 ?F) and 28 ?C (82.4 ?F) Store in a dry area below 90? F. Keep container closed.

TOXICOLOGICAL INFORMATION Relevant routes of exposure: Skin, Inhalation, Eyes Potential Health Effects/Symptoms Inhalation: Inhalation of vapors or mists of the product may be irritating to the respiratory system. When heated to temperatures exceeding 300? F (150? C) in the presence of air, silicones may form formaldehyde vapors. Formaldehyde is a potential cancer hazard and a known skin and respiratory sensitizer. Vapors irritate the eyes, nose and throat. Safe handling conditions may be maintained by keeping formaldehyde vapor concentrations below the OSHA permissible limit. The silane is a skin and eye irritant and prolonged contact may cause eye and skin burns. The low concentration makes such overexposure unlikely and minimizes its affect on health and safety. Skin contact: Causes skin irritation. May cause allergic skin reaction. Eye contact: Causes serious eye irritation. Ingestion: May be harmful if swallowed. Not expected under normal conditions of use.
