Section 4: First-Aid Measures

Description of first aid measures: In case of inhalation: If breathed in, move person into fresh air. If not breathing, give artificial respiration. In case of discomfort seek medical attention. In case of skin contact: Wash off with soap and plenty of water for at least 15 minutes. In case of discomfort seek medical attention. In case of eye contact: Flush eyes thoroughly with water for 15 minutes. Remove contact lenses after the initial 1-2 minutes and continue flushing. In case of discomfort seek medical attention. In case of ingestion: Do NOT induce vomiting. Never give anything by mouth to an unconscious person. Rinse mouth with water. In case of discomfort seek medical attention.

Most important symptoms and effects, both acute and delayed: Inhalation: Inhalation of dust may produce irritation, headache, metallic taste and/or cough. Severe exposures may produce shortness of breath, chest pain and flu-like symptoms: weakness, fever, headache, chills, sweating, nausea and muscular pain. Eyes: May cause irritation, redness, and pain. Skin contact: May cause irritation, redness, and pain. Ingestion: Symptoms can include severe nausea, vomiting, diarrhoea, abdominal pain, choking, dizziness and salivation.

Advice for fire-fighters: Wear self-contained breathing apparatus and protective clothing for firefighting. Further information: Standard procedure for chemical fires. Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.

Section 6: Accidental Release Measures

Personal precautions, protective equipment and emergency procedures: Personal precautions: Wear appropriate protective clothing. Avoid generation of dusts. Environmental precautions: Prevent product from entering drains. Prevent further leakage or spillage if safe to do so. Local authorities should be advised if significant spillages cannot be contained.

Methods for containment and cleaning up: Methods for cleaning up: Avoid generation of dusts. Carefully take up dry product. Forward for disposal. Clean up affected area.

Reference to other sections: Treat recovered material as described in the section "Disposal considerations".

Section 7: Handling and Storage

Precautions for safe handling: Advice on safe handling: Avoid generation of dusts. Change contaminated clothing. Wash hands after working with substance. Hygiene measures: Do not eat, drink or smoke when using this product.

Conditions for safe storage, including incompatibilities: Requirements for storage areas and containers: Store at room temperature (15-25 °C recommended). Keep well closed and protected from direct sunlight and moisture.

Section 8: Exposure Controls/Personal Protection

Control parameters: Occupational exposure limits: INHALATION Exposure Long-term: (DNEL) 580 µg/m³ DERMAL Exposure Long-term: (DNEL) 830 µg/kg bw/day

Exposure controls: Appropriate engineering controls: A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion into the general work area.

Individual protection measures, such as personal protective equipment: Eye/face protection: Use safety glasses. If there is a potential for exposure to particles which could cause eye discomfort, wear chemical goggles. Hand protection: Use chemical resistant gloves. Examples of preferred glove barrier materials include: Butyl rubber, Neoprene, Nitrile/butadiene rubber, Polyethylene, Ethyl vinyl alcohol laminate, polyvinyl alcohol, Polyvinyl chloride. Body protection: Plastic apron, sleeves, boots (if handling large quantities). Respiratory protection: If the exposure limit is exceeded and engineering controls are not feasible, a half-face high- efficiency particulate respirator (NIOSH type N100 filter) may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece high efficiency particulate respirator (NIOSH type N100 filter) may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive- pressure, air-supplied respirator.
