Reacts violently with water. Spontaneously flammable in air. Harmful by inhalation and if swallowed. Contact with water liberates toxic gas. Causes severe burns.Highly flammable.Lachrymator (substance which increases the flow of tears). Potential Health Effects Eye: Produces irritation, characterized by a burning sensation, redness, tearing, inflammation, and possible corneal injury. Lachrymator (substance which increases the flow of tears). May cause chemical conjunctivitis and corneal damage. Skin: Contact with skin causes irritation and possible burns, especially if the skin is wet or moist. May cause cyanosis of the extremities. Ingestion: May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause kidney damage. May cause cardiac disturbances. May be harmful if swallowed. Ingestion of large amounts may cause CNS depression. Inhalation: May cause kidney damage. Aspiration may lead to pulmonary edema. Vapors may cause dizziness or suffocation. May cause cardiac abnormalities. Inhalation at high concentrations may cause CNS depression and asphixiation. May cause burning sensation in the chest. Chronic: Effects may be delayed. May cause kidney damage. **** SECTION 4 - FIRST AID MEASURES **** Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Do NOT allow victim to rub eyes or keep eyes closed. Skin: Get medical aid immediately. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. If water-reactive products are embedded in the skin, no water should be applied. The embedded products should be covered with a light oil. Ingestion: Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water. Inhalation: Get medical aid immediately. Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask. Notes to Physician: **** SECTION 5 - FIRE FIGHTING MEASURES **** General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Reacts violently with water giving off flammable gas which may explode. Vapors may form an explosive mixture with air. Vapors can travel to a source of ignition and flash back. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Water Reactive. Material will react with water and may release a flammable and/or toxic gas. Use water spray to keep fire-exposed containers cool. May ignite or explode on contact with steam or moist air. Will be easily ignited by heat, sparks or flame. May re-ignite after fire is extinguished. Containers may explode if exposed to fire. Extinguishing Media: Use dry sand or earth to smother fire. Do NOT use water directly on fire. Use foam, dry chemical, or carbon dioxide. If water is the only media available, use in flooding amounts. DO NOT USE WATER! Do NOT get water inside containers. Do NOT use straight streams of water. Contact professional fire-fighters immediately. Cool containers with flooding quantities of water until well after fire is out. **** SECTION 6 - ACCIDENTAL RELEASE MEASURES **** General Information: Use proper personal protective equipment as indicated in Section 8. Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, observing precautions in the Protective Equipment section. Remove all sources of ignition. Use a spark-proof tool. Do not expose spill to water. Do not get water inside containers. A vapor suppressing foam may be used to reduce vapors. **** SECTION 7 - HANDLING and STORAGE **** Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not allow water to get into the container because of violent reaction. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep away from heat, sparks and flame. Avoid ingestion and inhalation. Do not allow contact with water. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Keep from contact with moist air and steam. Storage: Keep away from sources of ignition. Keep away from water. Flammables-area. Refrigerator/flammables. Keep refrigerated. (Store below 4C/39F.) Store protected from moisture. **** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION **** Engineering Controls: Use explosion-proof ventilation equipment. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Exposure Limits CAS# 10025-78-2: Russia: 1 mg/m3 TWA Personal Protective Equipment Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves and clothing to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin. Respirators: Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced. **** SECTION 9 - PHYSICAL AND CHEMICAL PROPERTIES **** Physical State: Liquid Color: clear, colorless Odor: None reported. pH: Not available.
