4. First-aid measures



The first aid measures for different exposure routes:



Inhalation: Remove to fresh air immediately. Do not permit exposed person to remain in dusty environment without adequate respiratory protection.



Skin contact: Remove from source of exposure. Remove contaminated clothing and wash affected area thoroughly with a mild soap and water. Wash contaminated clothing before reusing.



Eye contact: Do not rub eyes. Wash eyes under slowly running water for at least fifteen minutes, making sure eyes are held wide open and moved slowly in every direction. Ensure no solid particles remain in creases of eyelids. If so, continue to wash. If irritation persists, consult an ophthalmologist.



Ingestion: Treat symptomatically. If bowel obstruction occurs, immediately consult a physician.



The most important symptoms and hazardous effects:
EMERGENCY OVERVIEW: Product contains mechanical irritants to skin, eyes and respiratory tract and may present a nuisance dust hazard. Avoid breathing dust. Avoid contact with skin. Wear protective clothing including gloves, goggles or safety glasses with side shields and NIOSH approved dust mask.

EFFECTS OF ACUTE EXPOSURE: Dust may irritate eyes, skin, nasal passages and respiratory tract. Ingestion generally causes purging of the bowels, however, swallowing large amounts may lead to bowel obstruction.

EFFECTS OF CHRONIC EXPOSURE: No data available.

The protection of first-aiders: No special procedures or protection.

Notes to physicians:   No special notes to physicians.

5. Fire-fighting measures

Suitable fire extinguishing media: Product is not flammable or combustible. Use media appropriate to primary source of fire. Otherwise, use dry chemical, carbon dioxide, water spray or foam.

Specific hazards may be encountered during fire-fighting: No specific fire or explosion hazard.

Specific fire-fighting methods: Wear appropriate protective equipment; avoid breathing fumes or dust; keep upwind.

Special equipment for the protection of firefighters: None known.

6. Accidental release measures

Personal precautions: Ventilate enclosed spaces and use appropriate respiratory protection.

Environmental precautions: Prevent any spillage from entering drains or water courses

Methods for cleaning up: Sweep or vacuum spilled material in a manner to avoid generation of dust. Reclaim product for re-use, if possible, or collect in containers for disposal in an appropriate manner. Note: see Section 1 for emergency contact information and Section 13 for waste disposal.

7. Handling and storage

Handling: Keep container closed when not in use. Avoid contact with eyes. Avoid breathing dust and only use in a well-ventilated area. Consumption of food and beverages should be avoided in work area where product is being used. After handling product, always wash hands and face thoroughly with soap and water before eating, drinking or smoking.

Storage:

Keep under cover -- exposure to water may cause this product to slowly hydrate, during which heat may be generated (exothermic reaction). Otherwise, product is suitable for any general chemical storage area.

8. Exposure controls/personal protection

Specific engineering controls: Local and general mechanical dust collection and ventilation in accordance with good engineering practices should be provided to maintain dust levels below permissible exposure levels specified in Section VIII.

Personal protective equipment:

Respiratory protection: UP TO 100 MG/M3: Any dust, mist or fume respirator; any air supplied respirator; or, self-contained breathing apparatus.
UP TO 250 MG/M3: Any supplied air respirator operated in a continuous flow mode or any powered air purifying respirator with a dust/mist/fume filter.

UP TO 500 MG/M3: High efficiency particulate filter with full face piece; any powered air supplied respirator with a tight fitting face piece and a high efficiency particulate filter; any self contained breathing apparatus with a full face piece; any supplied air respirator with a full face piece.

UP TO 7500 MG/M3: Any air supplied respirator with full face piece and operated in a pressure demand or other positive pressure mode.

EMERGENCY or ENTRY INTO UNKNOWN CONCENTRATIONS: Self contained breathing apparatus with full face piece and operated in pressure demand mode or air supplied respirator with full face piece operated in a pressure demand or other positive pressure mode in combination with auxiliary self contained breathing apparatus operated in pressure demand or positive pressure mode.
