Health Hazards: For accidental take, it may cause diarrhea and may cause magnesium poisoning to persons of renal dysfunction with symptoms including gastralgia, vomiting, watery diarrhea, weakness, prostration, hard breath and cyanosis. For long-term contact of the powder of this product, it may cause inflammation of eyes and upper respiratory tract.
Environmental Hazards: It may do harm to environment and may cause water pollution.
Fire & Explosion Hazards: This product is non-combustible.
4. First Aid Measures
Skin Contact: Remove contaminated clothes and flush with plenty of water.
Eyes Contact: Raise eyelids and flush with water flow or normal saline. Get medical care.
Inhalation: Remove to fresh air. Keep respiratory tract unblocked. Give oxygen if breathing is difficult; give artificial respiration if not breathing. Get medical care.
Ingestion: Drink plenty of water. Induce vomiting and get medical care.
5. Fire-Fighting Measures
Hazard Description: This product is not combustible. It may release toxic fume from thermal decomposition.
Hazardous Combustion Products: Chlorine hydride and magnesium oxide.
Fire-Fighting Methods: Try to remove containers from fire area to safety places. Do not use full water jet to avoid spill fire or splashing.
Appropriate Fire Extinguishing Agents: Frog water, foam, powder and sand.
6. Accidental Release Measures
Emergency Measure: Isolate contaminated area and restrict access. Persons dealing with emergency are recommended wearing dust-proof respirators and uniforms. Do not contact leakage directly. For small leakage, just sweep it up, but avoid generating dust. Place it in bags and remove to a safe place. For large leakage, collect it for recycle or transport to waste-deposal place for appropriate deposal.
7. Handling and Storage
Handling Precautions: Handle in a confined area, but good ventilation must be quarantined. Prevent dust or powder from releasing into the air of workshops. Handing personnel must attend professional training and operate strictly according to operating instructions. Recommend wearing self-contained dust-proof respirators, safety chemical goggles, acid and alkali-resistant rubber uniforms and chemical protective gloves. Avoid generating dust. Stay away from oxidants. The storage area should be equipped with emergency equipments for leakage. The emptied containers may contain hazardous substances.
Storage Precautions: Store in a cool, dry and well-ventilated store room. Stay away from fire and heat sources. Avoid direct sunlight. The containers should be tightly sealed. Do not store together with oxidants. The storage area should be equipped with emergency equipments for leakage.
8. Exposure Control/Personal Protection
Exposure Limits:
China MAC: Not regulated
FSU MAC: Not regulated
United State TLV-TWA: Not regulated
United State TLV-STEL: Not regulated
Monitoring Method: Flame Atomic Absorption Spectrometry (FAAS) and Titan Yellow Colorimetry.
