Never give anything by mouth to an unconscious person. If conscious, wash out mouth with water. Get medical attention immediately. Page 2 of 6
5. FIRE-FIGHTING MEASURES Suitable (and unsuitable) extinguishing media Special protective equipment and precautions for firefighters Specific hazards arising from the chemical Flammable in the presence of a source of ignition, through friction or retained heat. Keep away from heat/sparks/open flame/hot surface. No smoking. Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Use appropriate media for adjacent fire. Wear self-contained, approved breathing apparatus and full protective clothing, including eye protection and boots. Emits toxic fumes (carbon oxides) under fire conditions. (See also Stability and Reactivity section). 6. ACCIDENTAL RELEASE MEASURES Personal precautions, protective equipment and emergency procedures Environmental precautions Methods and materials for containment and cleaning up See section 8 for recommendations on the use of personal protective equipment. Prevent spillage from entering drains. Any release to the environment may be subject to federal/national or local reporting requirements. Prevent spillage from entering drains. Pick up and arrange disposal without creating dust. Sweep up and place in suitable, closed containers for disposal. Clean surfaces thoroughly with water to remove residual contamination. Dispose of all waste and cleanup materials in accordance with regulations. 7. HANDLING AND STORAGE Precautions for safe handling See section 8 for recommendations on the use of personal protective equipment. Provide appropriate exhaust ventilation at places where dust is formed. Keep away from sources of ignition - No smoking. Take measures to prevent the buildup of electrostatic charge. Wash thoroughly after using. Keep container closed when not in use. Avoid formation of dusts. Conditions for safe storage, including any incompatibilities Store in cool, dry well ventilated area. Keep away from incompatible materials (see section 10 for incompatibilities). 8.
