Section 3 - HAZARDS IDENTIFICATION
  EMERGENCY OVERVIEW
Not available.
Potential Health Effects
Eye:
Dust may cause mechanical irritation.
Skin:
May cause skin irritation. Low hazard for usual industrial handling.
Ingestion:
No hazard expected in normal industrial use. Used as antacid.
Inhalation:
May cause respiratory tract irritation.
Chronic:
Chronic, long-term exposure to dust may lead to "benign pneumoconiosis."

Section 4 - FIRST AID MEASURES
  Eyes: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical aid.
Skin:
In case of contact, flush skin with plenty of water. Remove contaminated clothing and shoes. Get medical aid if irritation develops and persists. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.

Section 5 - FIRE FIGHTING MEASURES
  General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to extinguish surrounding fire.

Section 6 - ACCIDENTAL RELEASE MEASURES
  General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, observing precautions in the Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.

Section 7 - HANDLING and STORAGE
  Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid breathing dust.
Storage:
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
  Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
Exposure Limits CAS# 546-93-0: United Kingdom, WEL - TWA: 10 mg/m3 TWA (inhalable dust); 4 mg/m3 (respirable dust) United Kingdom, WEL - STEL: 30 mg/m3 STEL (inhalable dust); 12 mg STEL (respirable dust) United States OSHA: 15 mg/m3 TWA (total dust); 5 mg/m3 TWA (respirable fraction) Belgium - TWA: 10 mg/m3 VLE France - VME: 10 mg/m3 VME Malaysia: 10 mg/m3 TWA (particulate matter containing no asbestos <1% crystalline sili Netherlands: 10 mg/m3 MAC Russia: 10 mg/m3 TWA Spain: 10 mg/m3 VLA-ED (this value is for the particulated matter that is free from asb Personal Protective Equipment Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize contact with skin.
Respirators:
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
