SECTION 4. FIRST AID MEASURES
Always seek medical attention after first aid measures are provided.
Eye Contact: Do not allow victim to rub eye (s). Let the eye (s) water naturally for a few minutes. If particle/dust does not dislodge, flush with lukewarm, gently flowing water for 5 minutes or until particle/dust is removed, while holding eyelid (s) open. If irritation persists, obtain medical attention. DO NOT attempt to manually remove anything stuck to the eye.
Skin Contact: Remove contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Quickly and gently blot or brush away excess chemical. Wash gently and thoroughly with lukewarm gently flowing water and non-abrasive soap for 5 minutes. If irritation persists, repeat flushing. Obtain medical advice.
Inhalation: If symptoms are experienced, remove source of contamination or move victim to fresh air. Obtain medical advice.
Ingestion: Never give anything by mouth if victim is rapidly losing consciousness, or if unconscious or convulsing. Have victim rinse mouth thoroughly with water. DO NOT INDUCE VOMITING.
SECTION 5. FIRE FIGHTING MEASURES
Fire and Explosion Hazards: Flammable Solids. In case of fire and/or explosion do not breathe fumes. Dust may form explosive mixture with air.
Extinguishing Media: Use means of extinction appropriate for the surrounding fire conditions such as water spray, alcohol-resistant foam, carbon dioxide, dry powder, sand or talc.
Unsuitable Extinguishing Media: Water reactive. Material will react with water and may release a flammable and/or toxic gas. Do not use Water CO2 or Foam.
Fire Fighting: Apart from oxides of carbon. toxic fumes may result from combustion. Compounds of Calcium and Phosphorous may form. As with any fire, fire fighters should be fully trained and wear full protective clothing including an approved, self-contained breathing apparatus which supplies a positive air pressure within a full-face piece mask. Do not use water directly on material.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Ensure adequate ventilation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.).
Environmental precautions: Do not let the product enter drains, soil or water sources.
Methods and materials used for containment Cleanup procedures and Storage: Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite). Vacuum or sweep-up and remove to an approved disposal container.
SECTION 7. HANDLING AND STORAGE
Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. Wash thoroughly after handling. Do not drink, eat or smoke while handling. Avoid contact with skin, eyes and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. AKeep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.).
Conditions for safe storage, including any incompatibilities: Store in cool, dry and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Do not leave the material container open. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like strong oxidizing agents. Keep away from sources of ignition - No smoking. Take measures to prevent the build-up of electrostatic charge.
SECTION 8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Control Parameters: No occupational exposure limit values established.
Respirators: Where dust or fumes are generated and cannot be controlled to within acceptable levels by engineering means, use appropriate NIOSH-approved respiratory protection equipment.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Handle in accordance with good industrial hygiene and safety practice.
