Health Hazards: May cause mild irritation to eyes, skin, and respiratory tract. Prolonged contact might lead to discomfort. Ingestion of large amounts can result in nausea, abdominal cramps, and diarrhea.
Environmental Hazards: Can contribute to increased magnesium and chloride content in soil and waterways, potentially affecting aquatic life at high concentrations.
Chemical Name: Magnesium Chloride Hexahydrate
Concentration: Typically greater than 98%
Impurities: Trace amounts of other magnesium salts, possible presence of iron or calcium depending on source
CAS Number: 7791-18-6
Inhalation: Move affected person to fresh air. Seek medical attention if symptoms develop.
Skin Contact: Remove contaminated clothing. Rinse skin under running water for several minutes.
Eye Contact: Rinse eyes immediately with plenty of water, separating eyelids occasionally, seek medical advice if irritation persists.
Ingestion: Rinse mouth, do not induce vomiting. Provide water to drink, seek medical help if large quantities are ingested or symptoms occur.
Suitable Extinguishing Media: Water spray, foam, dry chemical, or carbon dioxide
Unsuitable Extinguishing Media: None known; product itself is not flammable.
Hazardous Combustion Products: Hydrogen chloride gas may form at very high temperatures
Special Protective Equipment: Firefighters should use self-contained breathing apparatus and protective clothing.
Other Considerations: Prevent fire-fighting runoff from entering drains or waterways.
Personal Precautions: Use protective gloves, goggles, and suitable protective clothing.
Environmental Precautions: Prevent entry into watercourses and sewers, minimize environmental contamination.
Methods for Cleanup: Sweep up spillage, avoid generating dust. Place material in appropriate, labeled waste containers for disposal. Wash spill area with water, preventing runoff into drains.
Handling: Avoid inhaling dust, minimize direct contact with skin and eyes, use local exhaust ventilation in areas with dust generation.
Storage: Store in tightly closed containers, in a cool and dry place. Seal properly after each use to prevent moisture absorption. Avoid exposure to incompatible substances like strong oxidizing agents.
Special Considerations: Keep away from acids and bases, segregate from food and animal feed.
Exposure Limits: Not assigned a workplace exposure limit, but dust exposure should be controlled
Engineering Controls: Use local exhaust ventilation, especially during bulk handling.
Personal Protective Equipment (PPE): Gloves (nitrile or PVC), safety glasses with side-shields, protective clothing to minimize contact
Respiratory Protection: Dust mask or respirator if dust levels become significant.
Hygiene Measures: Wash hands after handling, do not eat, drink, or smoke while handling chemicals.
Appearance: White to colorless crystalline solid
Odor: Odorless
pH (5% solution): Approximate range between 7.0 and 9.0
Melting Point: 116°C (decomposes)
Boiling Point: Decomposes before boiling
Solubility: Freely soluble in water, slightly soluble in alcohol
Specific Gravity: Around 1.6 g/cm³
Vapor Pressure: Not applicable (non-volatile solid)
Other Properties: Hygroscopic, forms solution on exposure to air due to moisture absorption
Chemical Stability: Stable under ambient storage conditions, absorbs moisture from air
Reactivity: Reacts with strong acids, bases, and strong oxidizers
Decomposition Products: Hydrogen chloride, chlorine gas at very high temperatures
Conditions to Avoid: Exposure to moisture, high humidity, strong oxidizing agents, acids
Incompatibility: Calcium hypochlorite, bromine trifluoride, and other oxidizers
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Health Effects: May cause irritation of eyes, skin, and respiratory system; large quantities may lead to digestive discomfort
Chronic Health Effects: No evidence of chronic toxicity reported at occupational exposure levels
LD50 (oral, rat): Not well-established; typically considered low toxicity
Carcinogenicity: No indication of carcinogenic potential
Other Data: Not known to cause sensitization, mutagenicity, or reproductive toxicity at normal occupational exposure levels
Ecotoxicity: Large releases can increase chloride levels in aquatic and terrestrial environments, which may harm sensitive plants and aquatic organisms
Persistence and Degradability: Inorganic salt, fully dissociates in water
Bioaccumulation Potential: Does not bioaccumulate
Mobility in Soil: Highly mobile due to solubility, leaches readily through soils
Other Adverse Effects: Large spills may alter local water chemistry
Waste Disposal Methods: Dispose of in accordance with local, regional, and national regulations. Small quantities can be diluted with plenty of water and flushed to drain if local regulations permit.
Container Disposal: Completely empty containers can be recycled or disposed of as non-hazardous waste.
Special Instructions: Avoid discharge to surface water; seek proper treatment or disposal at approved facilities.
