Protection of first-aiders:A rescuer should wear personal protective equipment, such as rubber gloves and air- tight goggles. Section5. FIRE-FIGHTING MEASURES Suitable extinguishingDry chemical, foam, water spray, carbon dioxide. media: Specific hazards arising Take care as it may decompose upon combustion or in high temperatures to from the chemical:generate poisonous fume. Precautions for firefighters: Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place. In case of fire in the surroundings: Remove movable containers if safe to do so. When extinguishing fire, be sure to wear personal protective equipment. Special protective equipment for firefighters: Section6. ACCIDENTAL RELEASE MEASURES Personal precautions,Use extra personal protective equipment (P3 filter respirator for toxic particles). Keep protective equipment and people away from and upwind of spill/leak. Entry to non-involved personnel should emergency procedures: be controlled around the leakage area by roping off, etc. Environmental precautions: Prevent product from entering drains. Methods and materials for Sweep dust to collect it into an airtight container, taking care not to disperse it. containment and cleaning Adhered or collected material should be promptly disposed of, in accordance with up: appropriate laws and regulations. Section7. HANDLING AND STORAGE Precautions for safe handling Technical measures:Handling is performed in a well ventilated place. Wear suitable protective equipment. Prevent dispersion of dust. Wash hands and face thoroughly after handling. Use a closed system if possible. Use a local exhaust if dust or aerosol will be generated. Advice on safe handling:Avoid contact with skin, eyes and clothing. Use corrosive resistant equipment.
